Engine Parts and More at Partsology.com

At Partsology.com, we get it: an engine rebuild isn’t the kind of thing just anybody can do, and we think it’s not the kind of thing an experienced mechanic would entrust to just any old parts supplier. That’s why all of us at Partsology.com are experts when it comes to engine parts. We are your #1 online source for engine rebuild kits and much more.

Whether you’re a seasoned hobbyist or a professional installer, you need someone in your corner. What you don’t want — or need — is a vague, potentially week-long turnaround on your engine parts.

Wouldn’t it be a real difference-maker if you could get what you need as soon as possible? We think your time is important too, and that’s why we guarantee next-day delivery on every order.

Partsology.com has the most complete inventory of engine parts in the business — if you look for it here, you will find it.
Our online catalog is also super easy to use. At Partsology.com, you can quickly find and order high-quality parts at low prices, and you can get everything you need with free next-day delivery — for orders over $75 — right to your door.

Our Specialty: Engine Rebuild Kits
Modern cars are not immune to catastrophic engine failure. Believe it or not, there are still some cars that have trouble making it to the 100,000-mile mark. Most shops usually recommend swapping a burnt OE engine for a remanufactured unit when that happens because the cost of an engine rebuild can escalate quickly. To keep the bill for those kinds of repairs under control, whether you’re interested in keeping costs down for your own project or for your valuable customers, it makes sense to get the best low-cost parts shipped to you as quickly as possible.

A professional installer knows that sometimes it’s easier, quicker, and more cost effective to rebuild the engine instead of yanking the whole thing out of the car and dropping in a remanufactured unit.

There’s a lot of ancillary work associated with a complete engine replacement, from dealing with the accessory drive to all of the electrical work and the plumbing for cooling provisions — and that’s putting it mildly.

When you select one of Partsology’s engine rebuilding kits, you’ve got options. Our kits allow you to select the parts you need so that you don’t have to buy a single part you don’t.

If you’re a professional installer, that means passing the savings on to the customer, and if you’re doing the wrenching on your own project, we don’t need to tell you how awesome it is to pay only for what you need.

Engine Rebuild Parts
Let’s say you don’t need anything that comprehensive. Perhaps you’ve got just a few things on your list. We get that, too, and we’ve got you covered — for all makes and models — on valve cover gaskets, main bearings, and everything in between.

If you need parts to rebuild engines, Partsology.com is the automotive supply industry partner you’ve been looking for.

Whether it’s a preventative head gasket swap for that infamous horizontally opposed Subaru 2.5 or an after-the-disaster total rebuild for a 2013 BMW X3 with a failed oil pump, Partsology.com has what you need.

Parts for Engines
Partsology.com isn’t just your #1 online destination for engine rebuilding parts or kits to rebuild engines; we’re also your go-to for anything you need for just about any engine you can think of.

Head Gasket and Bolt Kits
Wrenching on an early 2000s Subaru? Those are great cars, but their weakest link is their rather infamous head gasket issue.
