Need an opinion from a pro

[Tropicalthunder]

Just picked up a spyder gst w/t3 for next to nothing has an oil leak on two of the exhaust manifold bolts though, think I'll need a new head but any suggestions for maybe fixing the leak or is it a lost cause?

Only way to tell is to pull the manifold and check it out really..

what i figured thanks

when I pulled my manifold I remember oil came out of one of the stud holes for sure.. I figured it intersected an oil pathway so I put some rtv on the threads of the stud.. not sure if this is a recommended fix but I see no oil a year later..

This is correct, one of the upper middle studs does have an oil massage through it. I would start by checking for a leak around there. Are you sure the valve cover gasket is not leaking?

Excuse me for sounding dumb, but why would an exhaust manifold stud "go through" an oil passageway? They are actually called oil galleries. How would oil get through a stud?
If you drive a stud in the threaded hole further than where it is supposed to stop, you could puncture an oil gallery. Nobody I know would design an oil gallery that was deliberately blocked by a manifold stud.

its the same idea on lots of water pumps mostly trucks or rwd cars you need to clean the bolts and coat the threads in pipe thread sealant, its just how it is not always enough room for everything to fit or a design flaw, its not that its blocking an oil gallery, the end of the stud just partially goes into it it could only enter the gallery by 1/8'' and still leak bolts aren't a perfectly machined oil will still find its way through

Only pipe thread has a profile that's meant to make a fluid-tight seal. Fastener threads have a void at both the peak of the internal and external thread peaks. Permatex #2 is the correct solution.

Hey you guys are seriously the best thanks i think that should do the trick im sure ill have lots more questions later
