Just Fishing's 09 Tahoe Build thread

I'm running the standard pressure (blue) spring.
Sprung for the high pressure and high volume version thinking it's just built better.

I used this one


CHEVROLET PERFORMANCE HIGH VOLUME OIL PUMP - 12696357

that's what my brother runs on all the engines he builds

Used that one on my 1st motor. It failed, and I think that's why it spun a cam bearing.

Melling pumps are supposed to have some improved design, i forget details but "Melling = good" so i ran with that.

Hmm, interesting.

What failed on it?

Not exactly sure, but I was told motor went from no oil flowing. My oil pressure gauge hadn't worked probably for 1 year before the motor went. I didn't think it was a big deal at the time. I know better now.
This is the parts list from my original motor.

I wonder if the oring failed or a total pump failure. Hopefully I don't have the same fate. Like I said, my brother does quite a few of these a year, that's what he always runs. Bad batch I suppose. With my luck, I'll have one from a bad batch
