The symptoms are really piling up here. 93 toyota pickup 22re, I've got--
1) burning coolant,
2) high/surging idle when warming up and
3) oil in coolant.

Could this be an intake manifold gasket problem or 100% head gasket?


Planning to rent a car (or buy a nissan) and fix it in my driveway. Once its above freezing maybe.


thanks for any help.

 

A leak-down test might tell details of exactly where your troubles lie.

If theres oil in the coolant, its very likely the head gasket, or maybe a cracked head.

I don't think there's any way to put oil into the coolant from the intake manifold.

Edit: I guess that it might be possible for a timing cover fault to put oil into the coolant, but it's unlikely.

 

Ok thanks! I'll just take it apart and try and find out. Should not keep driving it, but i have to....

 

Quick non technical test. Top off coolant and start engine with radiator cap off. A blown headgasket sometimes will cause the coolant to shoot out of the radiator from the extra pressure in the system. Works betteron a cold engine. Revving the engine can do this as well but revving to high will throw coolant out as well.
