Oil and coolant mixed

[65btk]

I have a a inline 6 230 in a 65 c10. Was sitting since the 80s in a barn I was told. I got the truck running with fresh fluids. After a while of messing with it, the truck started shooting (pulsating) water out of the radiator with out the cap off. So I figured it was a blown head gasket. There was no coolant in oil or oil in coolant at that time. So I decided since the engine had good compression and I'm doing a budget build I would pull engine, clean every thing up with fresh gaskets and paint. Got every thing back together and fire it up. my new thermostat stuck shut an the engine over heated it while I was adjusting carbertor and timing. That resulted in coolant in my oil and oil in my coolant. I took the engine apart and it dont seem that the head gasket is noticeably blown. Did not see no cracks in cylinder wall or head. Any suggestion on where the are mixing at?

Did you do a compression test before you tore it down?...that woulda told you where to start looking..
I'm gonna guess cracked head if head gasket looks good...but it's just a guess..
How hot did it get when it overheated?

No I already tore it apart. When I went to the cab to shut off engine the guage was coolant guage was pegged out on the H. Is there a common spot they crack?

Hard to say now....

Since it's apart... I'd have that head magnafluxed for cracks at a machine shop.

I would have the block checked as well. The term budget build to me is doing it right if you don't have the money for the machine shop put it back where you found it.

I will get some qoutes from the machine shops and wieght my options. Might be time to just invest in a 350.

It wouldnt take much machine shop cost on the 6 to justify going sb...
