Oil in intake manifold

[axmarque]

Removed the intake manifold and found a good amount of oil in two of four runners. Any suggestions on what a could be?

It could be your Valve stem seals.

Or accumlated oil from your PCV system

Was it like this?

You guys think maybe it's from the lower spark plug tube seals? And it's not like the picture it's looks like fresh oil not burned

change your pcv valve.

run a breather filter at the end of the vc where the hose goes to the intake. That will clean some of the oil from going into the manifold again.

Clean the manifold if you removed it with degreaser and brake cleaner. Then I used a baby's bottle cleaner to scrub the runners.

If your doing all that with the manifold off also clean out your egr ports.
