    oops, I forgot to add that, the sending unit was replaced first and we still had low pressure, then the oil pump was replaced.

OIL LEAKAGE CAUSES


Where to begin? There are several things and areas that can leak oil or cause an oil leak. Super easy first, when changing the oil if it becomes overfilled it can seep from the seals, the dipstick, out the fill tube, through the gaskets, etc. This can be a permanent issue even if it only happened once or twice and the only repair is to replace the affected seals. Several other options for a variety of vehicles are as follows. Rear main, timing cover, crank seals, cam seals, valve covers, oil pan gasket or puncture, crank sensor, oil pressure gauge fittings, water pump mount (engine specific), head gasket, etc. Also transmission or transfer oil can push past bad seals or gaskets and bad transfer bearings can promote leakage in some models. The amount of oil leaked and location are key to identifying causes. If you are a "do it yourselfer" I recommend putting the vehicle up on ramps, wiping off excess oil with a cloth, then pressure washing (with degreaser for embedded road grime etc.) After the vehicle completely dries slide underneath with a very bright drop light and inspect thoroughly for drips or seepage. Always use proper safety precautions! If you cannot find the leak, start the engine and let it idle for a few minutes then shut it off, allow it to cool and re-inspect. There are several vacuum, gasket, valves, bent cam, and many other internal issues that can cause leaks as well. Hope you find this helpful, feel free to narrow it down for more focused help on this issue.

1997 chevy express van overheated now no oil pressure


sounds like possibly head gaskets, when you overheated probably warped heads causing coolant in oil and coolant in cylinders therefore partially hydrolocking...antifreeze does not compress like fuel vapors .check oil and see if looks like creme to light chocholate color. this means coolant in oil, this is very ******* bearings, eats them up and if thats the problem you loose oil pressure cause bearings are sloppy from being worn. Bottom Line.you might be looking for another enj.or rebuild

Alrighty. I've asked this a few times before, I have more info now. CHEVY 350 K1500. 1993. Replaced intake gaskets, (bad oil leak) dropped a small amount of coolant in with oil while doing so. Changed oil...


how did you clean the gasket off of the head? if you used a sanding disc the grit will eat up the bearings. are you reading pressure with a mechanical gauge? you have replaced all bearings??

6 psi @ 1000 RPM
18 psi @ 2000 RPM
24 psi @ 4000 RPM
this is chevrolet specs on oil pressure in your truck so you are within the range.

describe your idle problem more and i will try and help you with that

85 88 royale. Last summer replaced 1 of the valve


She should still have some life left in her. The water pump isn't too hard to replace, really no special tools needed. When motors get around that mileage, they will use some oil and have some leaks. As the engine wears, blow by developes and will cause gaskets to leak. I would also check the PCV valve.

What would cause a drop in oil pressure without any visible leak


the pressure bypass valve in the oil pump leaking by and not closing completely to make the pump build full pressure,or the pump is working and the sending unit is giving you a false reading,then you should have a mechanic put on a gauge to see actual pressure of the pump,don't wait cause if pressure is actually that low you will sustain engine damage soon

1992 Dynasty oil pressure drops at stops?


Hi I am Vortash sounds like you have one of four problems either the oil you are using is inferior and you need to upgrade to a better one synthetics are best ..
Your Oils pump is failing reducing the oil pressure ..
Leaky gaskets allowing pressure to ecape .
Or more drasticaly your main bearing shells are wearing giving the the oil more ways to escape under pressure . this is usually discernable by a knocking or rumbling noise especially on tick over .. hope it is just the oil for your sake regards Vortash

1996 DODGE RAM 1500 LOSES OIL PRESSURE AFTER WARMED UP FINE WHEN FIRST STARTED WHY?


There are several reasons. The oil viscosity can make a difference and if the oil is contaminated with fuel. Wear in the oil pump and all of your bearings starting with the main crankshaft bearings and the connecting rod bearings. The wrong or bad oil filter.
When cold oil flows it plugs leaking bearings and oil gears. When the oil warms, the wear in the bearings (gaps) can't hold back the thin oil and the pressure drops. If the bearings are replaced before the crank and cam are damaged, the pressure will be maintained.

1995 cherokee 2.5 td 150k miles will not start.


The oil pressure dropping to zero is common for cherokees. Replace the oil pressure sending unit and it will be good as new. Cracked exhaust manifolds are also common. Usually it will crack where the 2 pipes are welded into 1 pipe before it connects to the front pipe. There are lots of replacement headers out there to choose from. I just ordered one through quadratec.
