Resolved 2gNT Oil leak from lower intake mani bolts

[BLACK'98DSM]

Do I need to use sealant or gasket maker on the lower bolts for the intake manifold? Do they enter an oil passage? Oil is very slowly dripping from them.

I would be double checking everything. There aren't many places the engine could leak oil in that specific area.

Was anyone able to figure this out I may sound like a fools but iv replaced the headgasket and vc gasket and I swear it's leaking oil heavily from the intake manifold

Ya it's not leaking from the cover it's like it's pressurized I can also pour oil in and it'll come out the intake bolts

I'm confused. You add fresh oil and it runs out the head somewhere around the intake manifold? That doesn't make sense unless you have a hole in the head.

There are no intake mani bolts that enter an oil galley or the crank case (only the bottom middle exhaust mani stud does). So unless a longer bolt has been mistakenly pushed through the head, your manifold/bolts/studs are not the culprit.

Do you have the baffles on the inside of the valve cover? Is your PCV valve working properly? How's your oil cap seal? Any cracks on the valve cover?

Check for oil in your intake snorkel, pipes, and throttle body. If you find it there either you have a leaky turbo seal or are pushing oil out your crank case breather. That oil will accumulate at the intake mani gasket and eventually leak out.

Iv checked to see that all the exterior oil ports on the head are plugged and there good I swear it literally dumps out the head on the side it looks like idk I'm gonna get some oil dye and see if that'll help me narrow it down

Did you lose a BSPT plug?

I have a spare head and checked it to see where all the plugs on the head were and then looked at the head that's on the car and it has all the plugs it's a really weird one I'm gonna pull the valve cover and see if I can see where it's leaking from

Although unlikely, it is 100% worth checking. I circled them for you. Driver side of the head.
