We were out all day saturday, and all was fine. On the way back to the marina, I looked down and was at like 5-8 psi. We made it back to the marina fine, no noises, smells, explosions(ha!), etc...
Sunday, I fired it up at my work to flush it out. I checked the guage, and I was back to 40 psi, nice! 15 minutes later, i was at 5-8 psi again(sh*t).
Oil level is right where it needs to be, no oil in the bilge either. Any clues?
Oh, it's an '86 Comp, PCM 350.
