My brother has a 94 4runner with 3.0 and auto trans and their is oil in the radator. I think its the head gaskets. It has a rebiult motor with 10,000 miles on it. What do you guys think would leak oil into the cooling system?

 

i don't no much about the 3 slow but oil in the water generally indicates a blown hg.

 

blown head gaskets

 

Thats what i thought but was hope it would be something else. Gess im doing a head gasket job on my brothers runner.

 

Check the head for cracks while its apart. Here in NZ we have a few of these crack heads, tho not nearly as many as the old 2LTs (2.4 turbo diesel).

 

Rael common problem,head gaskets.Toyota has a updated gasket.

 

Not common for a 10,000mile old engine.. Who did the rebuild? You sure its not tranny fluid?

 

Sorry,missed the 10,000 miles.

 

unless its been ran hot.

 

how would tranny fluid leak into the radator? The radator fliud looks mike pudding. Its white.
