Question about 1985 Nissan 300ZX

Open Question

My Nissan 300 zx ,1985 with 95000 miles has low oil pressure

My Nissan 300 zx ,1985 with 95000 miles has low oil pressure at operating temperature , about 10 psa, at 2500 psi it is about 28 to 30 psi. I have replaced the guage last summer and also changed oil to 20 - 50 weight. It helped slightly. As it is costly to remove oil pan, ie need to drop steering any other ideas other than worn cam bearings or oil pump?

SOURCE: Oil not circulating ? 1999 Nissan Altima DOHC,

Well, from the oil pump it goes into your oil filter so the lines going from the pump into the filter could be clogged. check that and see. Also on most imports I have found that they have to be primed after the oil pump has been replaced. Buy a oil pressure gauge and hook it up. Disconnect your fuel and spark delivery and then just crank over your motor to make sure you have good pressure. It takes up to 30 seconds to build on some cars. hope that helps.

No, should have enough room to slide it out ,if not disconnect the engine mounts and jack up or lift up the engine just enough to slide the pan.

SOURCE: Rear engine oil leak....

Oil leak can be attributed to several factors.
1. Gasket failure.
2. Uncontrolled Crank case pressure Failure.

Tighten both the valve cover and oil pan bolts.
Replace the Positive Crankcase Ventilation Valve and vacuum line.,

This is a valve causes a negative vacuum on the engine while its running, As to say if it had a leak in a valve cover it should not be leaking while its running, only when the engine it turned off.

Hope this tip guides you in the correct direction to solve this problem.

I have a 05 z71 and lately on cold start up's the oil pressure gauge and info center tell's me low oil pressure for 3-5 seconds then the pressure comes up but not all the way after about 8-10 miles it

Oil gets thicker overtime and the oil filter gets clogged up with debris between changes/ cold environments cause sluggish thicker oil which takes longer warm and to reach its ideal viscosity operating temperature.A change of oil and filter would improve oil pressure reading on startup.

I changed the oil pressure switch on my 2007 Chrysler 300 but the light keeps chiming?

The you really do have low oil pressure? have this checked asap with a manual test gauge. Do not drive it until the cause is found or risk destroying the engine.

My 1990 300 ZX (non turbo) often fails to shift into overdrive at the proper time (according to the engine sound) eventually it may engage OD in a mile or less and often it goes for 20 or more miles before...

the problem could be a faulty switch itself...perhaps the fluid level is low..check it out and make sure its full and is good in color as well...then try to flush it and see if its an automatic car..

You may have a clogged fuel filtr, try getting the car plugged into the OBD port and get a read out code,then look up the code number for the diagnostics.. Auto zone will loan you a plug in or rent to you for small coins
