newb OIL PRESSURE?!?

[efsi703]

whats going on newb here. ive got a 91 lx and the oil light has been flickering and flashing. well i kept driving the car...like a dumb@$$, and broke my camshaft in half..so i put a new cam,and head on it, ive replaced the pressure switch, cleaned the clogged pickup screen and tube out. did a oil pressure test, at cold startup had 65 psi slowly dropped as car warmned up, after about 15-20 min pressure dropped to 8psi at idle BUT had 55-60 PSI at 3k rpms. would this indicated a bad oil pump? or internal problem (main crankshaft bearings)? any help is appreciated

How did the cam break in half?
also definitely sounds like a bad oil pump

damm that sucks bro...how does your motor sound?

[CB7Jay1]

Best bet, is to change the pump and hope for the best...It was probally the culprit all along.

[efsi703]

motor sounds fine,i will prolly replace pump and like u said, hope for the best.
would removing balance belt give me any advantage/disadvantage?

Sounds like you half-a$$ed the fix without proper inspection of the failed setup. Make sure you inspect everything related.

It is obvious you did not inspect your engine bearings or oil pump. If you abused your engine the way you described in terms of oil light, I would honestly start with another engine, unless you want to do a complete rebuild. You're more than likely on borrowed time, as engine bearings are probably damaged.

If you were driving with a bad oil pump there obviously was very poor oil circulation so there is a very good chance.Just look at what happened to your head.Change your oil pump and use a heavy grade of oil like 10W40 or 20W50

cool thnx for advice will do oil pump on sunday

[PirateMcFred]

If you're lucky you will only have a bad oil pump. If you're not lucky your bearings are shot and likely have have to replace/rebuild the shortblock.

If the oil pump is not the problem then in the meantime you can regain some of your oil pressure by running a thicker oil. Try a 15w50 and refrain from bearing on it until you source the parts you need to rebuild/replace the block.

well ive got the oil pump gonna put new one on tomarrow. is there any addition checks i can do with everything apart ? wat would happen if i leave the balance shaft belt off? the pump runs off the timing belt right

maybe a few extra hp IF the motor is still good....
that and a little more vibration. no real disadvantages aside from the vibes...

update-finshed today runs good with 10w40 left balance belt off was gonna pull shafts out of block but nah, and was gonna put belt on but nah. very slight vibes at idle. idc tho . oil light flickered once after 2 hrs running ...will do a pressure test soon.
