[V6-12v] Oil leak under intake manifold

Hi Jon --

You need to have a careful look around the valve cover, and head gasket
lines with a torch for the latter. Any leaks on the inside V of these would
tend to pool under the intake manifold. The other possibility is that there
is actually a pan valley cover which has a gasket, that sits right
underneath the intake manifold. If you don't see any leaks on the other
gaskets, that would be your most likely culprit. If it's this one, or the
head gasket, you need to strip off the intake manifold anyway, and it's good
practice to replace all the gaskets you disturb, of which there are quite a
few when you undertake that job. Best get back to the list when you've
decided exactly where the leak is coming from.
