not the exhaust pressure tested them already..........


has anybody given thought to head bolts leaking into valve train........I am told that without proper sealant on the threads the water can walk up the thread and drip into the valve train.....

Leaks don't always show up with pressure testing. Unless you get the manufacturer to test them and certify them then they are still suspect. The best way to check yourself is as I prescribed.

The oil cooler is a good call too. Easy to check.

That would explain water in the oil, but when i run the motor with just the manifolds on (gen 111) why would it only mist out of some of the cylenders....mainly the back


no thoughts on the head bolts lofty

If sealant or silly cone wasn't used, that would definitely be a problem

has anybody thought about condesation from the eng. running to cool, not able to burn off the moisture in the eng, it got two of my eng. due to clogging my oil filter , because of all the idling i have to do ,and i even have oil thermostats.......and only the thicker merlin block does it.

I have thought of this......Amoung all the other things, cold water, early season testing....I might be overeacting but the money i have in this mill is almost more than i can handle...

Trying to be extra cautious.........Plus the help and insight i get here is better than anywhere else.......


Thanks guys keep brainstorming

If you're getting mist in the exhaust and you run dry pipes then you've narrowed this down a bit. Head bolts? Maybe but I've never seen that happen, the gasket should still seal the water away from the combustion chamber and you would only get water in the oil. And just a bit at that.

It's going to be in the intake, the head gasket, or the exhaust.

I had the same problem. I pressure checked everything, no help. Made adaptors for the exhaust, collers and block. No indication. I finally followed some advice from this forum (REPLACE THE INTAKE GASKET WITH I CANT REMBER) Look it up and you will see which one to get. I should also tell you that I had 3#s of procharger boost on a stock engine and that add on took out the stock gasket. It is a cheep fix, you may just want to do it to eliminate one thing.

I've seen problems with Gen 6 heads on Mark IV blocks. There is a big mismatch in water jacket passages.
