oil pressure low at idle?
 

only when its been running a while, on cold startup, its high and healthy? any thoughts? the sender is about a yr old, and goes down to halfway mark at idle, until i hit the gas, usually it was one notch above the halfway on the stock guage, now when warm its a lil lower, should i be worried?

Sounds normal for an engine with 75k+ on it. Still junk the factory sender and gauge.

Take care,

Mine does the same thing. My car has 100k miles. It goes up while im driving so i dont worry about it.

mine does the same thing it jumps up when I step on the gas it goes up but at idle it is very low my motor has 75k

Mine did that for years then someone suggested a heavier weight and it works like a charm to bring the pressure up a bit.
although my pressure was realllly low! :eek:

Thanx guys, but i figured it out, i changed oil today, (and went heavier weight) but noticed my oil cooler was loose, i mean the nut in the middle, that hold it on, was backed almost all the way out, i dont know how it didnt leak? but i tightened that, and now, even with a hot engine at idle, it stays above halfway on the factory crap guage, heh, im going for some aftermarket guages soon i hope.....thnx again, just getting worried with this many miles, and im still revving her pretty high, love these cars!!:p are real tough, as long as you stay uunder 350 hp, they last forever!

OH, and also, i changed back to a fl1a, from a pure one, so far this has been the best filter to use, motorcraft.

You know those pure one filters and the fram filters are the biggest piece of **** IMO. I put a fram on a plymouth acclaim with a 4 banger in it, and it had about 1/4 of the gauge less oil press less than it had before I changed the oil! And the same thing happened when I put a pure one on it. I put a Delco filter on it and it was fine. Them sob's have so much paper in them, that you lose oil pressure. So I would say that putting that FL1-A helped you a lot.

Before I started screwing the the engine, I took my car to have the oil changed. I was talked into 5w30 because it was supposed to give me better performance.. the pressure got soooo low at idle that I changed back to 10w40 a day or 2 later.
