hey i posted this in 86 to 95 trucks and 4runners but i thought i would post it here too

ok here is the low down. buddys 4runner 3.crap. it has coffee oil under the oil cap but the rad fluid is clear? runs fine and has same power as always. it gets hot when going very slow or idleing for long periods of time in traffic, once it gets moving again it cools back down to normal. engine has 350k km's and had head gasket done 30k ago by PO. problem is he needs to have his runner to get to school and he is afraid it wont make it.

here is what we know is wrong with it - intake tube has a rip and PO duct taped it as a temp fix, thing eats rad fluid and has a leak somewhere. our thoughts were HG right? but wouldnt there be oil in rad too? anyways we need advice fast.

option 1. find a 3.4 and everything we will need and swap it during christmas break. we have the know how to do this swap as we have both been reading and reading of 3.4 swaps for months. problem is all the 3.4's around here are auto's we need 5spd! not so much worried about it being a auto because we would just need a 5spd ecu and wiring harness but we would rather a 5spd motor with harness and computer. basically if you guys could tell us everything we will need down to everything to get it up and running.

option 2. take heads off get them planed if worped, new HG's, new oil, fix intake tube, new rad, and check water pump. this is the easy way out but we were already planning for a 3.4 and dont want to put money into an engine that will come back out in 6 months haha.

like i said the engine runs fine rightnow and has not lost any power since we found this tasty coffee oil.

if you know of a cheap 3.4, 5spd ecu/ wiring harness, and can ship to us please give us a shout even if you know or have a cheap 3.4 just let us know what you want for it.

any input would be greatly appreciated! only thing dont tell us this will be hard and try and talk us out of it because we are fixing this thing balls to the wall lol. YT rocks and you guys are our only hope!! __________________

If there is a head gasket leak to the intake port then the coolant will be sucked into the cylinder. There will not be any oil in the coolant. If the oil under the cap looks like coffee, than I guess its just dark right, so change the oil. If you are talking milky coffee, is it thick like mayonnaise? If so then there is water in the oil.
Check how much steam is in the exhaust. Also if you cant see any steam, hold something over the top of the exhaust and let the exhaust condense on it. If there is any color to it (red or green - same color as your coolant) then there is a head gasket leak.

Fix the intake hose. Its 100% certain its leaking and the engine is running lean.

 

well it cant be the HG cuz the engine runs fine and there is no steam or anything out the exhaust. on the other thread we have narrowed it down to a water pump and intake tub. buddy ordered the parts so now we are just waiting.
