If you are looking for What Causes A Hole In The Engine Block, then you are on the right page. It contains sthe hole in engine block symptoms. Suppose you want the signs of a blown engine instead. Then this article is what you need.
The most catastrophic – and visual – is a broken connecting rod punching a hole in the block or crankcase. A hole in the block usually means a thrown connecting rod and a thrown rod is caused by excessive RPMs, excessively low oil level or no oil at all
A hole in the block usually means a piston/con rod broke and went out through the side. If the the block is damaged around the piston the block may need a sleeve. Cracks are much more difficult to repair and often have to have machine work done also, e.g. head cracking from a valve seat.

What Causes A Hole In The Engine Block
The holes in engine blocks do multiple things:
1: they are threaded and have the ability to screw bolts into them. This is done to hold things on like cylinder heads, water pumps, motor mounts, etc
2: they have oil flowing through them. The oil pump (most usually driven by the crankshaft) will push oil through a series of “galleys” that provide oil to other places in the engine. For example, there are often small holes in the crankshaft journals that allow oil to flow and lubricate the crank. When things that bolt to the engine require oil there are holes (for example at the cylinder head interface) that allow oil to flow into that part. you can see them on the top of the block
3: they have coolant flowing through them. Except for air-cooled engines, just like oil, the engine needs coolant. there are also other parts (again, cylinder head) that require coolant as well. There are passages that allow the coolant to flow from one to the other.
4: In addition on the coolant there are what are known as “freeze plugs” in various spots. These are usually metal discs about 2″ diameter (some smaller, some larger) that are made of a softer metal and pushed into the block. This is because when water freezes it expands, and if there is a freezing expansion inside a sealed block it can do a lot of damage. These freeze plugs are designed to be pushed out if the coolant freezes, and they can be easily replaced instead of replacing a cracked block from freezing.
5: and of course the cylinders themselves that have the pistons.
And sometimes you’ll find some holes that have no purpose at all, at least in the installation that you have. For example, you could have holes in a block that are not threaded and are used for attaching some accessory that did not come on the car that you have. Or a oil galley hole that has a plug in it.

Types of Crate Engines
Rebuilt or remanufactured engines are among the most widely available and affordable choices. All these terms mean is that the third-party seller took an existing engine with a good core and went through to ensure it’s back to factory specifications. Speaking of factory specifications, if you’re just looking for a direct replacement, this is probably the type of offering that’s available to you. It’s just as good as an engine that’s brand new.
The manufacturer of a vehicle may offer direct replacement crate engines for your car. For the most part, this is something that’s limited to performance or specialty engines, though. These engines are brand new, as though they were assembled to go with a car coming fresh off the assembly line. Because of this, you can generally expect the price point to be quite a bit higher than remanufactured engines.
Crate engines that are already worked over are also widely available. These engines can feature a list of custom parts such as pistons, rotating assemblies, camshafts, intake manifolds, and forced induction systems to meet a specific performance goal. As you can expect, these engines are often a lot more expensive than the previous types of crate engines that we visited. That said, they can be either brand new directly through the manufacturer or remanufactured by a third-party supplier.
Sometimes sanctioning bodies get involved and enforce a long list of rules for what parts engines used in certain events can or cannot use. Race car owners can either build an engine to match a specific list of rules or buy a crate engine approved by the sanctioning bodies for events. This is typical for something like circle-track racing. And yes, the tech inspectors might even go as far as looking at the engine internals on race day to ensure that the pistons and rotating assembly meet their standards, especially if it’s custom-built.
GM PERFORMANCE PARTS
Based out of Green Bay, Wis., GM Performance Parts builds and designs a number of products for vehicles. The company focuses on manufacturing transmissions, drivetrains, accessories, and both big-block and small-block crate engines. One of its most popular engines is the Genuine GM 350i / 5.7L Gen 0 Engine.
Formed in 1908, General Motors is one of the most popular and well-known names in the world of motorsports. The company’s central location is in Detroit, Mich., and it makes a number of vehicle accessories and parts, including the Chevrolet Performance 6.2L LS3 Engine Crate GM.
A company that has roots that go as deep as 1938 needs little introduction, especially when the founder has had as much of an influence on automotive culture as Vic Edelbrock did. This titan of a company works out of Torrance, Calif., and pumps out anything you’ll need to hop an engine up, even if it means replacing the engine with something like the Edelbrock Performer RPM 410 Crate Engine.
Despite Ford’s legendary triumphs in the world of racing that extend as far as LeMans, the Ford Racing division wasn’t introduced until 2014. Naturally, the headquarters is found in Dearborn, Mich., just outside of the Motor City. They produce pretty much anything you’d need to hop up your Ford, including the monstrous Ford Performance Parts M6007-572DR 572 Big Block Crate Engine.
Crate Engine Pricing
- $2,000 to $3,000: Remanufactured/refurbished engines typically fall in this range. It’s likely that the engines in this range require parts like the induction system and sensors for assembly.
- $3,000 to $1,0000: Complete engines and performance options can appear in this price range. For the most part, these are either high-performance factory offerings or custom assemblies.
- $10,000 to $20,000: High-performance factory engines and serious performance crate engines populate this price range. Performance and build-quality increase with the price.
- $20,000 and up: Exceptionally powerful engines are almost exclusive to this price range. Fuel injection, superior rotating assemblies, and even superchargers are typical for these crate engines.
Crate engine compatibility is something that has many meanings. For many, it might just mean ensuring the motor is a direct match for the application. For others, it can mean making sure that it’ll work with the parts they need for an engine swap. It can even suggest that the engine matches rules set forth by a particular event in some cases. In any situation, you need to do your homework to ensure that the engine reaches the criteria you need it to.
The amount of power that an engine puts out is something to pay close attention to. It’s easy to simply look at peak power, but you want to consider when it makes that power and how. Compression ratio, displacement, and power curves all tell you how that engine behaves. How and when it makes power ultimately tells you what kind of driving it’s good for.
USE OF APPROPRIATE PARTS
We can say that you want to make sure quality parts are used in the crate engine. However, that paints a broad stroke that doesn’t explain what you’re looking for. If it’s a factory-spec engine, “quality parts” is typically a descriptor telling you the engine uses factory equipment. That is fine for a direct-replacement engine, but those components may be risky for use on performance engines. If you’re looking for an engine that boosts performance, make sure to look at the types of pistons, connecting rods, and crankshaft used to ensure it’ll handle the power it produces.
INCLUSION OF PARTS YOU NEED
You’ll see that some engines don’t come with the induction system, sensors, and other parts necessary to their function. In the case that you can scrap these parts from your old engine, that’s not a big deal. If you don’t have an old engine to pull pieces from, you might want to consider a different crate engine. Sure, the long-block does make up for a significant portion of the expenses associated with engine building, but the small “nickel and dime” parts can quickly add up to a big price tag.
- Warranty Coverage. Just because a warranty is listed under “other considerations” doesn’t mean it’s not important. Crate engines often come with a warranty to protect the owners from any defects. Considering you can spend a massive amount of money on the engine, it is worth checking out the warranty to ensure your investment is protected.

BEST OVERALLChevrolet Performance 6.2L LS3 Engine Crate GM
Yep. We’re starting our list of crate engines with an LS. Don’t worry — there’s a lot to unpack here as it’s not just another LS. This is an LS3 6.2-liter engine that’s been suited up to perform. It’s turning a nodular crank that’s attached to hyper eutectic pistons via powdered connecting rods. While that is a pretty much factory rotating assembly, it’s capable of spinning out an impressive 525 horsepower at 6200 RPM and 486 pound-feet of torque at 5200 RPM. Most of that power output is due to an appropriate valvetrain, which just goes to show that you don’t need much to bring these engines to life.
As for those screaming, “just go to the junkyard,” we hear you. This price tag is quite a bit more than someone can use to turn out even more power with a used LS engine. However, the fact that this is a 500+ horsepower engine with a warranty makes it worth the consideration.BEST VALUEGenuine GM 350i / 5.7L Gen 0 Engine
Ever since the LS took the world by storm, everyone forgot about the “Mouse.” The Chevy 350 was once thought to be one of the most versatile engines in the world as it made its way into seemingly everything. That said, there comes a time when you need a basic 350 to keep your rig moving. That’s precisely what we’ve got here. It’s no monster performer, nor is it going to take your older Chevy car or truck into a whole new world of speed. That said, it’s every bit as reliable and compatible with any aftermarket parts that you could expect the classic 350 to be.
What’s the drawback? Considering this is the most affordable option on the list, you’d think we’d leave the price alone. But for nearly $3,000, you should expect a little more than the predicted 195 horsepower. Not only that, but there’s no induction system, which means you’ll be spending another couple hundred bucks to get it running.HONORABLE MENTIONFord FRDM6007-A52XS XS Aluminator Coyote 5.2L Crate Engine
This offering from Ford is a good example of the level of performance that’s available to you when you opt for a crate engine. Rather than having to sit down and figure out how to not only rebuild an engine, but make it more powerful, you simply pick the part number that gives you nearly 600 horsepower. This mighty Coyote 5.2-liter comes to your doorstep ready to make 580 horsepower at 7,800 RPM and 445 pound-feet of torque at 4,500 RPM. And don’t worry, the forged rotating assembly is more than capable of taking whatever you throw at it.
Of course, the drawback to this engine is that it costs nearly as much as a new car. We can groan about it all day long, but the reality of buying a crate engine often means you’re in for a considerable expense. Which is exactly why many opt to build rather than buy.BEST UPGRADEFord Performance Parts M6007-572DR 572 Big Block Crate Engine
Crate engines are known for supplying copious amounts of power and cutting down the amount of homework that builders need to do. That said, this 572 cubic-inch, or 9.4-liter, big block is a prime example of the kind of power that you can have delivered to your doorstep. This monster can wind up to put out an impressive 655 horsepower at 5500 RPM and an insane 710 pound-feet of torque at 4500 RPM. That’s more than enough to get any car or truck moving fast enough to rattle anyone’s cage. That said, the hydraulic-roller camshaft and beefy rotating assembly are more than capable of keeping things safe and manageable.
Of course, it’s no light expense. This is yet another engine assembly that costs nearly as much as an entire car. But, again, that’s something to expect when you want that kind of power.HONORABLE MENTIONEdelbrock Performer RPM 410 Crate Engine
Something like this really makes Ford and Mopar guys hate Chevy nuts. Why? Because it puts out a considerable 410 horsepower and 408 pound-feet of torque with a 9.5:1 compression ratio. So, not only is it producing 1.17 horsepower per cubic inch, but it’s doing it on pump gas. That may be possible for any engine with the right build, but the cost is about what you’ll invest in parts for those other platforms to get the job done — never mind machining and assembly. This thing even comes with the carburetor, water pump, and harmonic balancer. That makes it pretty much a true drop-in option.
There really aren’t too any drawbacks to this model. No, it’s not the most powerful option, but it really doesn’t need to be. About the only thing to complain about is the impossible standard this type of crate engine produces for folks outside of the GM world to look for.HONORABLE MENTIONFord Performance Parts M6007-M50C 2018-2019 Coyote 5.0L Crate Engine
Ford’s Coyote engines are notoriously expensive. As you can see from some of the options on the market, you can spend a serious amount of money to obtain one of these platforms. This particular engine is pretty much on the low side in terms of dollar value, making it a far more favorable option for many. That said, it’s a factory-spec 2018-2019 5.0-liter Coyote. That might seem a little lackluster, but remember that these engines are rather impressive in their natural configuration. It’s a great option for someone who needs to replace the worn engine they’re working with, or someone looking to Coyote swap whatever they’re working on.
The price is high, but it is what it is. It is high for a direct-replacement engine, but these Coyotes aren’t exactly the most affordable option from the get-go. You might be able to save money if you’re lucky enough to cop one from the scrap yard. But Ford nuts are hot on it, so your chances of doing so are slim unless you’re Johnny on the Spot.HONORABLE MENTIONPROFessional Powertrain DDH8 Chrysler 5.7L Hemi Engine
We admit that Mopar isn’t seeing much love throughout this entire piece, so it’s only appropriate to squeeze in an example. In this case, we’re looking at a remanufactured 5.7-liter Gen 3 Hemi. It’s a remanufactured bit, which gives us peace of mind knowing that a good engine wasn’t melted down and turned into a set of skillets. All joking aside, this is a great option for folks needing a replacement engine for their 04-08 V8 Mopar commuter that’s seen its day. It includes everything from the block and rotating assembly to the cylinder heads and valvetrain, effectively cutting down the number of parts you need to pull together to get your rig running again.
Being a long block, the lack of an induction system, a timing cover, and sensors means there’s still a fair bit of work ahead of its new owner. You’ll either need to pull what you can from your old engine or buy all new parts that could tally up to a considerable expense. We should also note that this is the truck Hemi, meaning Challenger and Charger owners would likely want to consider a different option.HONORABLE MENTIONGenuine GM (12568758) 5.7L Gen1 Truck Engine
Use this engine to replace a tired, worn engine. The engine allows you to start with this economical production motor, then you can add your choice of power-adding accessories.
It’s a 5.7 liter, 350 cubic inch engine that fits in 1987-1995 light GM trucks (under 8,500 pounds), but you can adjust it for use in many other small-block applications. It uses a late-style, one-piece rear main seal and the motor’s cylinder heads have center-style cover hold downs. Other details include a machined fuel pump (no hole for the fuel-pump push rod, though) and a gear-driven oil pump assembly. The motor develops 210 horsepower at 4,000 RPMs. Torque is 300 foot pounds at 2,800 RPMs. It has a cast-iron block, one-piece rear seal, two-bolt main caps, and a one-piece nodular crankshaft. Compression ratio is 9.4 to1.
Note that this engine cannot be used in marine applications.
- Don’t rule out short blocks. You might not find a crate engine that suits your needs, but that doesn’t mean you’re out of luck. You can purchase a high-performance short block to fit heads and a valve train that’ll meet your demands.
- Don’t go with more than you need. It’s tempting to invest in a more powerful engine. Keep in mind that more power is more wear and tear. The factory transmission and drivetrain might not be able to keep up with the power you’re introducing, leading to significant headaches and more expenses.
- There’s still plenty of work ahead of you. Crate engines don’t install themselves, and you’ll need plenty of time to “drop one in.” Not only does that mean that you’ll need the tools for the job, but enough time to do it right. Always remember that things never go the way they’re supposed to. Calculate that into the time you set aside to work on your car.
- Be conscientious of who you’re giving your money to. There are a shocking amount of suppliers offering crate engines. Be aware that not all are as respectable as they make it seem. Take the time to research the suppliers and find one that you know you can trust.
- Consider your machine shop. Just because an old motor is worn down doesn’t mean it’s junk. Your local machine shop can likely breathe new life into an engine by honing the cylinders, rebuilding the heads, and so on. It’s always a good idea to support local businesses, and the machine shop can even build an engine custom to your demands.
