I am having a pretty severe leak from here, I have tried putting oil resistant gasket maker on the threads and oil is still getting out. Can anyone give me any tips to stop this?

 

You sure it's not leaking out the intake itself? Teflon paste is the best for threads.

 

I prefer this, threads need to be clean, obviously. I use it on trans temp senders at the pressure test port with no leaks (90-100psi). Teflon pastes eventually harden and get crumbly, even the 'non-hardening' sort I used to use on head bolts.

Smoke test to make sure the intake isn't leaking like SS RRR said.
