Oil pressure

Asked by Apr 25, 2016 at 03:02 PM about the 1998 GMC Sierra 1500 C1500 SLE Extended Cab SB

Question type: Maintenance & Repair

Ok so when driving the oil pressure is at 1
line above 60 and when I stop it drops
down to about 45 no noise or rattling but
after sitting for about a minute it drops to
40 then starts rattling and tapping  down
by the oil pan. I just changed the oil a day
ago and that's when it started

gm is nice because on most you can fill / prime the oil filter before installing it...i changed the oil on a 60s 289 ford years ago and before it primed / flowed it spun a rod bearing... anyway...go and get a bottle of lucas oil additive and add it to your oil...it cant hurt....ok !

OK thanks.........and also while sitting there in the park I give it a little gas to raise the oil pressure the noise will stop
