Hey tearsbeers, great deal on that van! Anyway, I have an 03' H2 Hummer and I noticed something similar problem that you had, but mine you have to drive it for at least along time in order for the oil pressure to drop, but very slowly. Also, I recently replaced the oil sensor and it's doing the same thing. No engine knocking or any type noise. Hopefully you can help me out or anyone out there knows whats going on. Thanks.

well mine idles at 40 psi cold start then drops to 30 psi when at 205 deg. then after 30 minutes or so it will drop to 25 psi when idling but thats the lowest it will go

what ive read in my shop manual is that you need 6 psi per thousand rpm's minimum so if you have say, twice that much its not a problem you have to fix immediately.

need more info on your H2

how many miles does it have?

what what weight/what kind of oil do you use how long does it take for the oil pressure to drop,what psi does it drop to?

Wow. 327k miles. I have a 2005 Chevy Express cargo van 155 wb 4.8 engine with 167k miles. I guess it has a lot of life left. I have a lot of power options. But no rear air. Wish I had that in Florida.What engine do you have? 4.8 or 6.0? You stole that van for that price. Good Luck with it.

Nice score for under $1500! I would of probably yanked the engine out and made it into a donor for my Camaro lol. Good luck with it!
