so who knows the 22RE?

just picked up an 87(?) 4runner tonight, and I havent had a chance to look at it yet, but heres what I know so far....

a friend of mine just bought this from someone else, but then needed cash, so I bought it from him to help him out...and I have wanted one for a while anyway...the guy he bought it from told him it had a blown head gasket, but I'm not so sure about that (I only drove it a few miles, after letting it sit and idle for about 15 minutes)

it does seem to be a little low on power, but then again, I'm used to driving an F250 with a 460, so theres bit of a difference there...it does smoke out of the exhaust some, but doesnt seem to do it except at idle...it doesnt run hot, and does put decent heat out of the dash...it runs a bit rough, but that could be just ignition problems, or anything really...

when my friend first got it a couple weeks ago, he was driving it home (all he really did with it) and said it started to get hot (I dont kow what temp that actually means though) so he pulled over and let it cool down, then realized the coolant was low, so he filled it up and drove the rest of the way without any problems...it was still full when I drove it back here tonight, so I dont think its just leaking out, or at least not when its cold...I didnt see any hitting the ground when I got it home either...

I'll be checking it out this weekend, just wondering if there are any known problems to look for...


I dont intend to put much money or work into this engine, since I have a Blazer sitting here with a 4.3 Vortech that will probably be finding a new home in this Toyota later this summer...

Things to watch for:

overheating like that can warp the head and kill the head gasket pretty easy. So watch that.

The timing chain has plastic guides, it'll wear through those, they fall apart and down into the oil pan. The chain can also wear through the metai into a coolant passage.

Be carefull with spark plugs, its real easy to cross thread them in the aluminum head

many times the supposed "blown head gasket" is in fact the timing chain eating through the guides and into the timing cover.

Run a compression check to be sure it isn't the head gasket.

actually, I already knew about the timing chain guides...I think I actually have a new timing set here somewhere for a 22R, I'm assuming these didnt change with the EFI??

was kinda thinking it may be a timing issue, along with some other minor problems, and planning on doing a compression test on it sometime this weekend, if I get time....LOL...

all 4 cyls run 120-125 on the compression test, and plugs didnt look too bad....couldnt pressure test the cooling system because I dont have the adaptor for the small radiator opening...
but one thing did seem kind of weird, while doing the compression test, the cooling system seemed to be building quite a bit of pressure (but I dont know exactly how much pressure)...the oil looks and smells OK (just dark), so there isnt any coolant in it, and it doesnt appear to be getting any oil into the coolant either...
so my question now is, where the timing chain wears into the coolant passage, could that lead to crankcase pressure building up in the cooling system, without any cross contamination? that is, assuming there is a problem with the PCV system...

I also noticed that the dist is turned so that the bolt is to the furthest point in the slot, but there is a clean spot about the same size as the washer on the opposite side of the slot, so I think someone has changed the timing recently....hooked my timing light up and it looks like its set at about 8-10 BTDC without jumping the terminals at the test connector...this could be wrong since it was getting late, and I didnt clean off the crank pulley and paint the mark on it...the sticker on the hood says to set timing at 5BTDC with the terminals jumped....I'm going to check that again tomorrow, along with pressure testing the cooling system...

Get a combustion gas anylizer for the coolings system. I've found this to be the best tool for the smaller questionable head gasket leaks.

the cams wear down on those pretty bad too, which doesnt open the valves all the way killing power.

No on the cross contamination thing. IIRC it wears into a water jacket that is on the pressure side of the water pump and just dumps water into the pan. Pressure in the cooling system is an indicator of a blown HG. 120-125 PSI seems low I think 145 or so is stock. Did you perform a leak down test?

no, I didnt do a leak down test, but for all 4 cyls to be within 5psi of each other, I wouldnt be concerned with a loss of 20 psi compression over the last 21 years...

I have driven this, and it isnt too bad on power...I'm sure it can run alot better then it does, but it isnt terrible as is...

Nuggets, I actually meant to grab my combustion gas tester from work today, but completely forgot about it, along with the adaptor to pressure test the cooling system...


I'm not too concerned with it, since I'm pulling the entire drivetrain with auto trans/case/ECM/harness and putting a 4.3 Vortech in this 4Runner, just wanted to know the condition of this engine so that I can sell it after I get it out, or possible fix it before selling it...I'm not interested in trying to sell an engine unless I know the condition of it...

I ran into that once I started loosing coolent very slow then boom water in the oil and bad day for Bob.
