Replaced the gasket around the oil pump, and the horrible clattering noise went away.
The oil pressure was GREAT until this morning. I removed the dipstick to check the level, the level was fine, but after replacing the dipstick the level on the guage dropped and got lower throughout the day...
Car's running great, except for that. Oh, it was about 10 degrees warmer today than it has been, ~64 F.
What wt oil are you running? Oil sort of turns to grease at really cold temperatures. Also been told a cheap oil filter, think Fram, can produce a drop in oil pressure.
Just curious but where in the world do you live?
Thirty year old car. I would guess the dipstick is worn out and he needs a new one ;)
10W30, IIRC.
As far as the Fram filter...er...I gotta go to AutoZone....
The Great Northeast, Leftern Massachusetts...
Ooops my math is bad.
Reminded today of old Chevy I kept around for the kids. In a 6 month period it only had 60 miles on it. Figured insurance was costing $10/mile. Got rid of it.
Winter beater. Comes out usually around November. Replaces this:
Hmmmm, maybe the screws came loose? checkout page 12 here;
I think what JiKy said about the Fram filters might have a bearing too, although I don't use the 'cheap' ones, but AutoZone was selling a 'special' with 5 qts oil and a Fram ToughGard thrown in free.
I noticed the oil p on my Supra was lower than usual, and I used the same combination on that car as well. Didn't have that issue with Bosch or OEM Toyota filters. I've been using Frams on the Suby since anything else is about 1/5 the cash value of the car! ;0
I guess I'll get a better filter next time...
And don't forget to check the "oil pisser switch" -a bad sender (leaking) is not at all uncommon.
I took a look at all that when I did the gasket. Looked OK.
I think the Fram filter is the culprit, but I just changed the oil before the 'season' started and have 2,000 more miles to go! ;)
Had to ask. 82, I think. 1.8L SOHC TBI.
oil, filter and switch is a lot cheaper than an engine.
EA81 or EA82?
That makes it an EA82. In your original post I thought the temperature was a minus 64 degrees. Had a hard time believing anywhere in the world is that cold at this time of year. Check the wire that runs to the pressure sender. Thinking it is secured to the oil dipstick tube. Maybe it broke or something when you checked the oil level. Yeah, a really long shot. But if the "lifters" aren't clattering this alone means you still have decent oil pressure.
