oil pressure!!! HELP!!!
in the 89 RS camaro im getting the oil pressure gauge reads 0 at idle, then when you get going it reads 15 to 30 "the needle fluctuates", engine runs smooth, no smoke... i check the oil it was down
1 qt of oil... also dirty...

whats wrong?

 

it's a possibility that ur oil passages may be wearing out, zero oil pressure though si definately never a good thing, and an engine should alwayz have oil pressure while running, if it doesn't you're gonna wind up with a very not working engine before long. If ur passages aren't wearing out, (becoming so large that it won't maintain propper pressure, and it'd require a lot of oil to fill the given area, it would also explain why it flucuates once the oil's warm, because the pressure isn't steady , instead it's bouncing because of inconsitences with the galleries, so that's a possibility) Another shot would be ur oil pump is failing, and won't provide much presssure untilthings have warmed up a bit, not sure which though...more likely than not the first . But the second is definately a possibility too, also...is your oil filter clogged up? it might be, with our airplane engines once we change the oil on a plane, we cut the filter open and inspect for pieces of alluminum that might have broken down in the engine bay, easy way to help maintain a proper running engine. But good oil filters will have a bypass valve, so if the filter is unfortunately clogged, it won't starve the engine of oil, instead it'll just not filter it...which isn't much better than the clog, (but a lil better) since apparently they're stuff in the oil that was able to clog the filter in the first place.


good luck bud.

 

possible that your oil pressure sensor is going bad or blocked.
