304 low oil pressure
We were on a family trail ride last week, 2 Jeeps and a Dodge pickup packed full of kids and food.
While climbing a fairly steep trail I heard some lifter racket, and saw oil pressure at 0. Dropping the rpm's to <1200 or so brought the pressure back.
Babied it back to camp and checked the oil. Right at the add mark. Put in a quart and went out to find a hill to check it out again.
It was better now but still when I got her really steep up or down pressure would drop clear to 0. It seems to me if the engine hasn't stalled out it should still have oil pressure.
The armchair mechanics at camp had ideas of a loose oil pump pickup tube or the dipstick wasn't the correct one for the 304...
I could see the pickup idea, but since it loses pressure going up AND down, that doesn't make sense to me.
As for the dipstick, I know I put in 5 qts plus a little at the last oil change. No leaks and she doesn't smoke.
Pressure at idle cold is around 50 and warm around 20.
I don't have a lot of history to tell, I've only had this one for 8 months or so.
I'm not familiar with 304's, both of my previous Jeeps had the Buick 225. So feel free to call me a ******* and point out the obvious (hopefully).
