Had my 460 rebuilt at a reputable machine shop. After the 4 time out I found water in my oil so I called the machine shop. They told me to check the intake and heads bolts. I ask them if I have a blowen head or intake gasket hows it on NOT THEM he said I should have check them. So I checked heads good intake had 5 loose bolts, 2 on one side and 3 on the other. I retightened the intake and then pulled the plug and the one side with 3 loose bolts had a wet plug. Ran a compression test all cylinders were close. Will keep an eye on it hopefully the gasket didn't get messed up. My question is if very thing was toqued properly should I have to check them.
