Ok so we had the intake off recently and after we put things back together we found water in the oil. I'm not finding any in the cylinders and none is blowing out the exhaust so I'm guessing I didnt get the intake gaskets sealed up and its leaking into the oil valley.

Any other ideas or am I close on this one? I didnt have water in the oil until this change so I'm thinking this is the issue.

Thanks for everyones input

if it was sitting on top it probably happened when you pulled the intake.if it was mixed then id worry about it.

What I do when resetting an intake is take 4 long 3/8 bolts and cut the heads off to make guides for the gaskets and the intake, the gaskets like to slide around a bit when setting the intake without guide bolts.

I thought about the water in oil part from removing the intake but I've changed the oil and filter and its still milking up.

So I'm still holding to the thought that I must of missed on lining up the gasket/intake.

wrench, not a bad idea on the stud guides. I usually line up the gasket on the head then use some silicon to hold it in place. let it set up then bolt on the intake.

I'm guessing its just not sealed up in a spot or two and is feeding oil into the valley area.

We had water getting into the oil once and it was from a cracked rocker stud just above one of the water jackets.

same thing happened to me this weekend. the guy that built my engine used a bolt that was about 1/8th of an inch too long on the end of the intake and it didnt pull the intake down tight enough and leaked water into the valley and out of the end . I put a shorter bolt in and it stopped!!

make sure the intake gasket ports are not to big. I made that mistake, looked good
on the heads, but when I took it back
apart, the ports on gasket were to big for the intake and water was going in from the
back water pass.

I had this happen once. It was on a victor jr. intake manifold. Obviously you used silicone on the ends of the engine block instead of the cork or rubber gaskets, right? Sometimes these gaskets will hold up the intake if you have plained the heads excessivly. What I did on my motor was put a small bead of silicone around the water holes on the cylinder heads and it worked. Just my two cents.

redid the intake and gasket and everything sealed up fine. got a small squirter from one of the front bolt holes but it was fixed easily with silicone.

Thanks guys.

hey wrenchturner just coat gaskets and heads with brushtack or gaskasinch and lay gaskets on heads for a bit. the gaskets will stay in place but they wont be too stuck. i also use it on my rockr covers and i reuse same gaskets all season. it sure helps me
