Does fuel pressure come up on the aeroforce guage?? I have a pretty much brand new acdelco fuel pump that was installed several months before this happened.

Thanks for the link. I just found one like that on amazon for like $15

machinegunsquid suggested a bad PCV valve causing air coming out of the oil fill port. That would be the best case scenario. I just picked up a new one for $3 but haven't put it in yet.

What should 104s be gapped at with my setup?

What should they be gapped at? I forget... .045? .050?

Yep, the combination of blow by pressure and the conditions of the plugs do not look good. Chipped piston def seems to be the consensus

why do you think its going to misfire?

So what should be my next step? compression test? or scope? or replace spark plugs and pcv valve since I have new ones here???
