What exactly does a rebuilt engine consist of?
If i were to moderately rebuild my 22RE motor, what would I have to look at replacing?

Usually how much does a rebuild cost in parts + labor if you have someone do it?

 

you don't really replace much of anything... if you wanted to replace stuff, you would simply buy a new casting (where possible) or get an engine from a salvage yard, such as the Toyota-specialized Yota Yard...

rebuilding an engine (I've seen the process) involves completely taking it apart outside of the vehicle and restoring the components to as new of a condition as possible. Any componenets that are either broken, nearly broken, or unable to be satisfactorily restored should be gotten rid of and you start over with fresh ones...

as far as cost goes, you could spend anywhere from $100-700 on up to $10k depending on tooling/labor requirements (i.e. whether or not you can/feel like doing it yourself) and the condition/life history of the engine itself.

I have to warn you though... rebuilding an engine is like consummating a marriage. You and your engine will never be the same if you decide to go through with it. If it still runs good, don't even bother.

 

Alright, thanks for the advice.

Absolutly nothing is wrong with it. I hear funny sounds now and then, but the truck is 16 years old. I can always rely on her to start every morning, its just the thought of things going South with a 197k under her hood.

You know?

Anyone else feel this way?

 

My first 4runner's engine went south at 177K and my second 4runner is still going strong at 199550.

A rebuilt engine is next on my list of things to do because I don't want to have a rod give out on the trail.

 

If it aint broke dont fix it....

 

Good morning,
I've been visiting this site for a year now & would like to ask further on this. I'm picking up an unassembled complete 95 22RE (w/ intake, exhaust manifold) today with an engine stand for $250. The guy told me it had 80k on it, but wondered why he tore it down. I have a 93 p/u (which I bought for $1200) w/ 131k in Sept and have put 30k on it in 9 months and only ran into a worn water pump and stripped exhaust stud. I'd like to try this rebuild as a project (for a spare) and would like some add'l tips of what to look fwd to. I have tools, but not too mechanically (financial mgr) inclined but can follow instructions. My bro says I'll need a torque wrench & the stand will help. My question is how will I know by looking at the cylinder walls if I can just purchase a gasket set and reassemble this puppy? Anything else I should look at? I appreciate any responses and look forward to the add'l wealth of knowledge that you Yotatechers provide. Thanks. DJ

 

by looking at it you will be able to tell a few things. The color and look of the piston tops and cylinder walls can tell you a lot. Check and replace the basics-- HG, Water Pump, and the seals

 

I would disagree and say that rebuilds are part of preventative maintenance/service.

 

If it truly has 80K miles on it I would be suspicious as well. Take the block, crankshaft, and head to a good machine shop and have them cleaned, inspected and measured. They will be able to tell you if you have serviceable parts or not. They should also be able to tell you what parts you need to replace and the sizes as well. At a minimum you will need a gasket set, piston rings, and a set of bearings. You would be wise to replace the oil pump, timing chain/gears, and possibly the camshaft if it is not pristeen. Most likely the head and possibly the block will need to be decked to ensure they are absolutely flat.

An engine in a box is always kind of a crapshoot. You hope the guy has not lost pieces, especially bolts and sensors. And as you say, you never know for sure why it ended up that way to begin with. On the positive side, you have your old engine to cannibalize for missing stuff. Get a good service manual or two. There is a '93 manual online (do a search) and you may want to pick up a Haynes manual at your local auto parts store. For parts, search here for sources. I got mine from Engnbldr - good prices, good quality and great service.

Thanks for your comments, as they will be greatly considered. The seller mentioned that he wanted to "pep" it up for his 4Runner, but realized the cost of it wasn't feasible and purchased a Landcruiser instead. I'll send pictures when I get it tonight. I wouldn't proceed with the purchase if I didn't have this knowledge base. Appreciate all your comments.

 

I agree with everything Badtz said and would also recommend reading a book on rebuilding an automotive engine. There are a lot of tricks and tips you will learn from someone who has done it before. If you know someone locally, get them to help you out. I've done about 5 complete rebuilds and at least as many top ends and there is no way someone could explain every nuance through an internet forum.

Finding a reputable and friendly engine shop would be my first move. They can be an invaluable reference as well as provide services that you might not be able to handle.

Good luck on a great project!
