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.

If cleaning the engine does not work, replace the oil press. sending unit. These senders on Jeeps have had a history of problems where they will work one day and not the next day.

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 took years for seals to harden & wear.

SOURCE: Valve cover leak oil

My suggestion would be to spend about $20 on a Haynes or Chilton manual and they will walk you through it. Most part stores have them.

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.

Will go in gear but car will not move

Does it actually go into gear? Look under the air cleaner housing at the top of the transmission and check the grommet that goes around the shift mechanism have someone in the car move it, then you will see the grommet is broken or missing. The fix here is basically buying a new cable just because the crappy grommet busted, if you can push the grommet out of the new cable you can install just the grommet without tearing the car apart.

2008 chevy aveo cover gasket

Replace the one fastener. Typically you don't have a torque sequence on a valve cover.

Keep an eye on the oil leaks. Problems like this one are why we mechanics don't make enough money. Everyone wants to fix it themselves and we go hungry because it looks easier that it really is. (Not being rude, just stating facts)
I hope you fixed your issue, and don't have any further problems. I would recommend taking it to a pro if you continue having issues. Something seemingly small like this can snowball quick.

Take it from a pro who has been there, done that, have too many teeshirts. :-)

Xterra 05 bypass valve in the oil pump stuck - oil valve goes up and down

sounds to me like your rear timing cover gasket is blown out, and your oil pressure varies due to the leak. you will have to remove front cover and check the oil passage covers for gasket missing or blown. pricy repair, time consuming. have done dozens of those.

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.

i bought a used 2004 mitsubishi lancer ls sportback with the same problem. a google search told me this was a known defect and was covered under a dealer recall--no cost to me. my local dealer did the job. it took at least a half day--the entire dash, they said, had to be removed. the fix isn't perfect, but it is light years above and beyond what it was b4. the new knobs aren't silky smooth, but the old ones needed tools to turn!
