Having problems with your 2000 Pontiac Firebird ?
1999 firebird 3.8L low oil pressure at idle only when hot
\015 My 99 firebird with just over 100,000 miles has a similar issue, when driven for maybe 30 minutes, the oil pressure at idle will drop to around 40 psi and be good, mid range above idle. I also see a slight fluxuation once the pressure is lower at idle. The needle jumps around maybe a 5 psi flux,(35-40). Anyone have any ideas what could be causing that? Also there is a noticable dent in the oil pan, but I would think if this was restricting the oil pick up it would cause problems when cold as well and at higher rpm. Any thoughts, ideas, suggestions please email me and or post here.\015\012Thanks,\015\012John\015
Your oil pump does that on purpose - more noticeable with a dented oilpan as pressure is slightly increased. nothing to do until it goes (if it goes) unless you want to throw parts at your car anyways.
