Oil pressure

heavychevy85 · 09-05-2008, 07:48 PM

i was driving my truck for the first time in a while on the road atleast i just put a bunch of new parts on it and wanted to see how it rode well any way i got about two miles down the road and my oil pressure gauge droped to around 20psi when coasting and the same when sitting still the motor runs great the oil is at full cuz i just changed it about two months ago. the only thing i can see were there is oil leaking from is the oil pan gasket and the front and rear seal that goes with it so any help will be appreciated

Okay, in addition to the PM we just exchanged, if there is a small oil leak.. then odds are the oil pressure dropped because the oil level dropped. But like I said, those gauges do move around quite a bit...

mine jumps around too, but you mentioned that it is not running right either which indicates to me there is other issues

um... YES... IF you mean in the oil....LOL... and do not expect to go very far! LOL... but as for the coolant, not really this time of year, but you are going to wanna get that out before winter or you will freeze the block...

Is this carbed? Like I said before, are you getting gas or water in the oil?
