Hi, I put a crate 350 in my s10 and it ran fine until the waterpump belt broke and I didn't see the temperature guage go up. The result was what I thought was a blown head gasket, lots of water in the oil. I replaced the head gaskets and it ran fine for an hour or so and once again there was water in the oil. I pulled the heads and check the gaskets, no sign of damage to the gaskets, nothing blown through. I pulled the valves out of the heads and I can't see any cracks anywhere. Cylinders 5 and 7 seem darker, there was crap on the underneath side of the intake valves but that is all I can see. I'm thinking the heads are cracked somewhere where I can't see them. What do you think? Should I pay to have these heads cleaned and magnafluxed or should I save the money and just get some new heads? Has anyone run across this before? Any help would be appreciated. Rick
