Topic: 10 year old rebuild 22re

[12 valve]

I bought my 87 4runner from an old man that rebuilt the motor and let it sit for the next 10 years. Im not sure if i should just finish putting it back together or pull it and take to the machine shop to see what all it needs. when i say let it sit i mean no oil in engine intake is off of it header is off valve cover was bolted down and head and oil pan are bolted down but thats about it.

[toyotanner]

were the exhaust and intake ports plugged? or did he leave them open?... if they were plugged and he says he rebuilt it i dont see why you couldnt just finish putting everything back together... maybe check the timing marks just to be safe

[Snowtoy]

Where was the Runner stored, outside in the elements or in a garage?

[OOPS]

I would at least pull the head to check for rust. Hopefully he used a lot of assembly lube and oil when he put it together.

ports are open

x2 put it togather and see how it runs, if it's bad then just rebuild it your self

Pull the head and oil pan check for rust and check to see if the bearings still have assembly lube on them. you can pull a main cap or two for giggles to check them. if all of that is good poor a little motor oil in-between the pistons and cylinder walls, let it soak in for a few and turn it over by hand to make sure everything is free and the rings didn't rust to the cylinder walls. if every thing checks out slap a new head gasket on it and bolt it back together. That's what I'd do.

Ok so now I came across a 22re out of an 88 truck that has been sitting for two years. The engine was wrapped in plastic. It has 170,000 miles on it. He wants 500 for everything and will it work in my 87?

[83 Crawler]

Yup it should

[toyotanner]

yes it will

[Sparkplug]

The longblock will, the injectors will not, and I believe none of the plugs will match your 87, but I could be wrong. 88 is a b*std year as far as the efi part is concerned

[12 valve [OP]]

I can get the computer and wiring harness from the 88 too

[Snowtoy]

A used engine w/170k on it will be a bit of a crap shoot, if it was well maintained it might run trouble free for a few 100k, if it was abused it could crap out on you within a 100 miles. 

Have you inspected the engine that came with it yet?  What did the PO say was done during the rebuild?

[12 valve [OP]]

Just said it was a total rebuild bearings bored head water pump. Said his son didn't want to work on it anymore so It just sat for the next ten years until I seen it and pulled it out of his yard.

[crawlinrunner]

I  would remove spark plugs. Remove the oil pump and prime with vasoline and oil, put some oil in each spark plug hole and turn it over by hand. Making sure everything turns easy, even and quite. If so run it.

If you don't find any rust on the cam or the crank, and don't find any signs that something has been nesting in the head, your probably better off just completing the rebuild of the engine that came with the Runner over buying the used one. 

If you are concerned about the seals and gaskets, you can get a new gasket kit for under $200, and replace them yourself, or see what a machine shop will charge to tear it do it, if you don't have the tools/space/desire to do it yourself.

I will try to pull it apart on sat morning and post back what I find

[12 valve [OP]]

I think I'm going to run the bottom end and was thinking about going with an engnbldr head and cam and lc header

[79coyotefrg]

was the cam and valves rusty??   if not do like posted above and pull the sparkplugs and put some atf in the cylinders and let it sit over night.   if this works it will save you a butt load of $$

as soon as it sits over night spin it over by hand if you feel a spot has unusual resistance stop and pull the head if not.  hook the battery up and spin it over with the starter till you see oil pressure.  then run a compression test and post back.

[12 valve [OP]]

Pulled the oil pan and all looks good. Now do I pull the head and look at cylinders or now what ?

[79coyotefrg]

did you see any signs that a mouse or bugs had been in the ports??  if not then I would pull the spark plugs and squirt some atf in the cylinders and let it sit over night and then tomorrow roll the engine over by hand.  if nothing binds spin it with the starter but without plugs.

[12 valve [OP]]

I was going to pull the head and check for rust.

[79coyotefrg]

that is probably best.  be sure and use a Toyota (dealer) or D&J Rock  head gasket.

[12 valve [OP]]

Pulled the head and the front cylinder has a scar on one of the walls should I try to hone it or any help would be great

[Snowtoy]

Location and depth of the scar will be helpful, can you post a pic?

[12 valve [OP]]

I will try. It runs almost the length of the wall and my finger nail catches it

[79coyotefrg]

is the piston good and tight in the cylinder??  if it is then make sure whatever made the scratch isnt still there.  the previous owner probably just put new rings in and didnt have it bored

[12 valve [OP]]

All the pistons have a 2 on them and some have a 2 and a 3 or 4 also what does that mean

[79coyotefrg]

I cant remember off hand but its not important.   almost all stock pistons have those numbers on them and they never (at least I have never seen them) correlate to piston position in the block aka #1 piston etc

[12 valve [OP]]

Can I reuse my old rocker arms on a new cam
