question on a 91 4runner
v6 4x4 5spd. i bought this 4runner and the guy i bought it off of re did the heads and gaskets. theres a tad of water getting into the oil. now he tells me the problem is the round part on the left side on the engine block he calls it there oil cooler thats getting water. the coolant suppose to cool down the oil. ok soits a round thing with a bolt in the middle. anyone know the name or heard of this problem? thanks

Possible solution........
Just a reminder to folks that there are o-rings and a gasket in the cooler that are needed to keep the coolant separate from the oil. This is a place where a worn seal will allow pressurized coolant to get into the oil, so it's important to replace these seals periodically.

i bought the gaskets for the oil cooler and just have it replaced for the heck of it. but right now its in the shop there gonna put the timing belt back on and run a compression test. hopefully it's good cause the guy i bought it from just had the heads re done and still was getting water in the oil. some im hopeing its the oil cooler seals.

air getting into the water.
update
ok so i got it back after putting it together then the new radiator blew it started leaking so i got a new one. but my mechanic told me there was air getting into the water. he told me it could be the intake, heads not torqed right, bad head gasket or cracked head.

yup the heads just got done too before i bought it less than 200 miles on the rebuilt heads. the guy still thought water was getting into the water. but i heard you have to change the oil a few times after doing a head job to get most of the water out. so he ripped the intake back off and just left it like that so i bought it had it put back together since the heads held compression still but when i had the intake put back on they didnt put all the bolts back in im alittle ticked since a second opinion shop pointed it out to me. the first mechanic told me there was air getting into the heads turns out he didnt put every bolt back in for the intake.
