SOURCE: Oil leakage

You have an open hose from valve cover to no where which oil is coming out of....hmmmm, I would think yes..... If you still have a problem with oil blowing out of motor after those are fixed, sounds like you may have back pressure.

SOURCE: 2001 Grand cherokee 4.7 low oil pressure in cold weather.

I'd suggest using a good brand of synthetic oil (which was actually developed a really long time ago for the armed forces for use in polar reigions) Most flushes loosen too much material all at once, causing blockage of the oil pickup screen. You can get a bit more cleaning and lubrication protection by adding a bit of marvel oil to the synthetic. Change just the filter (and lost oil) about every 1500 miles, till the problem subsides.

SOURCE: oil leaks

clean off the area where you suspect the leak is then run and check. The only way to change rear main seal (and have it actually work) is by removing crankshaft. I have seen this attempted at least a hundred times and never seen one yet that didn't leak. Some of the new oils for "older engines" have a seal softener in them tha usually will help but don't expect results for months...it took years for seals to harden & wear.

SOURCE: Oil pressure problem on a 2001 tj wragler 4.0 sport

If you are using antifreeze, regardless of the mechanics test results, it cant just "disappear" it must be going somewhere!!! My guess is that it's getting into the engine and causing the oil pressure problem. Likely you either have a small head gasket leak or a small crack in the cylinder head that only opens when hot. Instead of a pressure test have a hydrocarbon test done on the radiator as well as a cylinder leakdown test. One of those tests as well as oil pressure test with a mechanical pressure gauge, should tell you more about what is going on.

I changed my oil pump on a Chevy Silverado HD and I don't have oil pressure Now


The relief valve in the pump is stuck open or missing the spring. Is the plastic coupling for the drive in place? Oil pressure should be 30 psi. or better. Also check the pick up tube for looseness in pump. Air leak will not prime the pump.

92 toyota cressida oil leak does the timing belt cover have upper and lower gaskets seperate? i bought gasket had it and front main seal gasket replaced still leaking though


Pressure inside the engine is the cause of most oil leaks. Imagine you having a mouthful of mashed potatoes. They probably won't leak out until something makes you laugh or sneeze, increasing the pressure. You don't have a gasket problem, you have a pressure relief problem.
Either you have worn cylinder rings and/or a blocked PCV valve or other emission system malfunction.

Location of Oil Pressure Sensor and Oil Pressure Relieve Valve


the oil pressure switch is on pssenger side, lower engine area,beside oil filter, mounted in engine block. The pressure relief valve is in the oil pump, in which case, you have to drop the oil pan,and take off the oil pump.
