Hi everyone. Ive been hiding behind the scenes reading things around here for a while, and finally realized I should just ask you guys instead of wondering and figuring things all out by myself.
I bought a 91 explorer that obviously had water leaking into the oil, and also into the combustion chambers because it was going out the exhaust.
I took the heads off, and the gaskets look horrible. Obviously they were leaking. However, then when looking at the heads, there are small (hairline) cracks between about 4 intake to exhaust valves. so 4 out of 6 cylinders DO have small cracks. 1 of them actually has very minute traces of rust around it.
Are these heads done for? Do they leak already? Will they leak soon? I hear these cast heads are different than the aluminum ohc heads im used to in my 280Z.
What do you guys think?
Buy aftermarket casts online? (both heads for $450 shipped), or put in nice new gaskets and take my chances?
thanks in advance
