Wheelhop Posted September 26, 2006 Share Posted September 26, 2006 I've recently entered the world of retro scoobs. I picked up an 86 GL-10 wagon I plan to rallycross. I'm in the proccess of tuning it up and fixing leaks removing ac ect. I haven't driven the car at all accept to get it home after replacing the snapped timing belt in the previous owners driveway. It seems to run and sound alright. What has me worried is that at idle the oil pressure is hovering just over the 0 mark, at like 0.5 psi. If I rev it a little it slowly climbs to like 3 psi. Then it settles back to 0.5 again after about 15 seconds when you stop revving. Should I be replacing the oil pump? Little more info: the car has 208kms, sat for about a year, is an auto, 4x4, FI, turbo, air ride. The oil leaks it currently has appear to be the valve cover gaskets. I'm hoping its not the head gaskets. Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 26, 2006 Share Posted September 26, 2006 Replace the sender first - sounds like it's dead to me. But before you do anything, take a reading with a REAL mechanical guage to verify. GD Link to comment Share on other sites More sharing options...
Wheelhop Posted September 26, 2006 Author Share Posted September 26, 2006 Sender? Do you mean the sensor? If so I'll start with that. I'm trying to not spend to much on the car but oil pressure is sort of important. So I guess I better spring for the mechanical gauge. Thanks.

NorthWet Posted September 26, 2006 Share Posted September 26, 2006 Replace the sender first - sounds like it's dead to me. But before you do anything, take a reading with a REAL mechanical guage to verify. GD +1 Oil-pressure sender unit attached to the oil pump. Tends to die or get damaged. I can get one of mine to read negative pressure at idle. If your pressure was really that low, you woul like hear the hydraulic valve lash adjusters (HLAs) ticking/clattering/knocking.

daeron Posted September 26, 2006 Share Posted September 26, 2006 installing a mechanical gauge is a wise idea for any car youre going to race. may as well fail to trust the factory water temp gauge while youre at it, and hey why not add a boost gauge too.. theres a nice little bay below your ashtray where three gauges will fit quite nicely.......

kotty Posted September 12, 2007 Share Posted September 12, 2007 You probably need to take a reading with a mechanical guage to verify it. likewise, i can't get one of mine to read negative pressure at idle.But then my Subaru Oil Filter need to be replaced.I'm trying not spend on the my car but it's sort important.

dragonfire Posted September 12, 2007 Share Posted September 12, 2007 i had the same problem, replaced the stock unit with and aftermarket gauge. i think i spent a total of 30 bucks for the gauge and the extra line to feed inside the car. did not buy autometer or anything like that. just some wierd name i never heard of. hell it was 20 bucks and it changes 7 different colors. yes it is a little ricer fellas, but i change dash colors like yall change sock and shoes. would like to match some how. seems i can match my clothing colors but i can match dash colors:rolleyes: Link to comment Share on other sites More sharing options...
