22re antifreeze in oil
Hey all,
I usually don't just post up and ask a question but I want to know other people's knowledge/experiences.
I have a 85 4runner that was just dumping antifreeze in the oil. I did a compression test, 150 psi all across. I tore it apart, the head gasket was fine. I've been searching for cracks and haven't found any yet. The guides on the timing cover were both messed up but somehow she still ran decent.
My main question is.. How do I go about looking for internal cracks? And where would a crack commonly form on what component? I've just been looking at the timing cover, head, and block coolant passage ways and can't seem to find anything yet.

you can take your block/head to a machine shop they will you some chemical and lights to check it hold on let me search the name. so the thing i was thinking of is magnaflux but thats only for aluminum. im not sure if that will help so im going to post it but sorry in advance if it doesnt help

very carefully inspect the timing cover. Any gouges near the waterpump = leaky cover = coolant in your oil.
new covers are available from a few aftermarket sources.
you can always pull the valvecover, and pressurize your cooling system with a pressure tester (to 15-20psi) and look to see if there's coolant seeping into the chain area.
