Re: weird smell???????
Yeah, I'm pretty sure but could be wrong.
This is from comparisions betwixt my truck (98 s-10 4.3) and two ZR2's (Blazer, '99 and truck, 2002).
I would think that oil pressure running idle at 15 psi is not good!
But then again it would also depend on the viscosity you're running. I'm still working with 5w30. The weather doesn't change much here in San Diego so I don't need to make any drastic viscosity changes.
At cold the pressure is WAY up there, about 60-75 psi and goes down around 45 psi at idle, sometimes lower but never down to 15-20.
But if this is wrong for the 4.3's then I need to do some serious systems checks!
