Low oil pressure? 97 z28
Alright.. So I had a problem breaking valve springs, so I upgraded to some high lift springs from crower. Now, before I changed springs and valve stem seals, my oil pressure was around 20 at idle (950 in drive). I was using Mobil 1 sythetic, 10w-30 and a fram filter(i know.. bad bad).
Since I changed the springs, I used castrol syntec 10w-30, and an AC delco filter. Now my oil pressure is around 10, and drops down to 0 sometimes once the car is hot, and I come to a stop. Any RPM above 1200, and the OP is always above 20 psi.
I'm just wondering if the syntec oil might have caused my OP to drop, or if some metal from the broken spring got in my bearing =\ maybe a bad sending unit?
Any help would be appreciated =)
