oil pressure to low at idle??

jasons_98gt · June 27th, 2008, 02:17 AM

hey all hows it going?

Got a 98gt with almost 150k well the oil pressure specs 25-40psi at 1500rpm while the engines hot which is fine cause i get between that and 60lbs while driving the only thing that concerns me is after driving for a while especially in the city at idle the guage is showing only 10-15lbs til i get back on the move...does this sound normal to anyone? any input would be great thanks

sounds like you could have some problems... i was showing 10-15 at idle and this is what happened to my motor...

did u motor make a slight knocking or clacking like noises when you did a cold start and go away after about a minute matt?

MustangMatt96GT · June 27th, 2008, 02:40 AM

not before... it blew up. BUt it also didnt have low oil pressure but at the track one night.

well the mechanics arent diagnosing my oil pressure low because at a cold start its putting out almost 70lbs and when it under load the pressures all in specs only at 750 rpms its getting like 10-15 when its hot from like city driving and shit been that way for almost 2 years i figured he must be right or i woulda blown by now

oil pump on its last leg or a bad sensor some place tellin the comp it doesnt need that much oil at that certain time maybe

Oil could just be low... Have you checked the oil at least?

jasons_98gt · July 1st, 2008, 10:26 PM

yea i checked the oil and changed it as a matter of fact im not worried about it i had 3 mechs tell me today that its getting 12lbs at 750rpms which is good cause as a rule of thumb its like 10psi per thousand rpms like i said im not sweatin this lil shit anymore its been like that for 3 years if it was a problem the motor woulda burned up by now

low oill pressure will make your bearings go bad... starvation ya kno... If you corner hard while on the gas you'll hear the bearings grinding if the oil is low.
