Default where could my oil leak be coming from

Im confused...

So im replacing my intake manifold gasket as the shop i go to told me thats the reason for my oil leak yet i find the old gasket to be pretty well intact and and black rtv seems to be fine and i dont see where oil could be leaking from it...


Anyways the water ports seemed to be leaking so im going to replace it anyways but my question is where else could i be leaking oil from

This is not a drip drip oil leak it only leaks when driving the car as i have never ever seen a spot of oil under my car yet there is oil burns on the exhaust

i looked at the pan and that seems to be fine and the head gasket seems to be seeping a tiny tiny bit of oil through the cork like its soaking it up and letting some come out but where else could oil be coming from


the only places i see oil wanting to drip is under the oil pan bolts

p.s. the previous intake manifold gasket was the fel pro 90301-1 permatorque which is that hard matertial one which i believe edelbrock says not to use with their aluminum manifolds

i will be replacing it with a fel pro 1250 printoseal


lets say if i install this and i still have a leak will i be able to reinstall it using a fresh coat of black rtv incase i need to replace the head gaskets?

What indication do you have that you are leaking oil? Oil on the ground? Or are you just having to put oil in it every once in awhile?

You would definately notice a quart a month making a mess. You may be burning it. And, as for reusing the intake gasket, technically you should NEVER reuse an intake or head gasket. However, I have on my own cars. It's up to you but it does create the potential for one more thing to go wrong. I am confused about one thing. You said the head gasket seems to be leaking through the cork. Head gaskets aren't made from cork. Are you sure you aren't seeing a valve cover gasket leak?

no i meant the oil pan gasket has cork the head gasket i cannot see at all but some oil is under the head gasket as well but it might just be grime and what not from driving
