2007 Yukon xl denali burning oil


If you smell burning oil, you may have a leak in the engine compartment reaching the exhaust manifold and burning on contact. The most common cause for that is leaking valve cover gaskets. If you are losing oil with NO signs of external leaks, the engine may be burning it internally. Valve stem oil seals, worn piston rings, blown/leaking head gasket are a few causes of that.

2004 gmc yukon lite came on low oil pressure just had oil change 5 days ago checked it was low about a qt. Has 157,000 miles what can be the cause


There can be alot of causes, such as valve covers leaking, oil pan gasket leaking, oil filter leaking, rear main seal leaking, front timing chain cover seal or gasket leaking even bad rings. Does it smoke out of the back? Your valve seals could be leaking. Best way to find out if you have a leak is to inspect the valve covers manually, or take newspapers and lay them under the entire engine on the ground, and it will leave the tell tale stain of a leak. Hope this helps.

I have a 2003 yukon Problem with the GMC Yukon XL


What size engine ? 4.3 L vortex P0300 random misfire code is usually associated with vacuum leaks , but could also be low fuel pressure , plugged fuel filter , fuel pump problem , clogged injectors etc... doing fuel pressure an flow testing would confirm or eliminate that as a problem . Fuel injector balance testing would confirm or eliminate clogged injectors .

Possible transmission oil leak


absorb the frluid into a white paper towell ... if it is red in color then its transmission fluid .... if its clear or brown then its likely engine oil ... if the transmission is leaking a little then there are additives that can be put in the transmission to soften the seals .. that will often fix small seal leaks ...if the leak is slight and not damaging driveways then its not likely to cause major trouble as long as you keep your eye on the transmission fluid level .. ... if its engine oil then you could have a leaking valve cover gasket, oil pressure sending unit (sensor) ... or it could be jjust from spills as oil is changed or added .

Master seal leak.


It's not usually called this, perhaps it was a "main seal leak"? Suffice it to say that it is not possible to replace this seal without removing the engine or the transmission as it resides behind the flywheel. Or perhaps they said "master cylinder leak", in which case it is a matter of replacing the brake master cylinder with a rebuilt unit or at the very least, the seals on top of the master cylinder that mate with the brake reservoir.

Rear main seal leak


Hi,

If somebody told you that you have a main seal leak what they meant was the round seal that is around the circumference of the output shaft of the crank. This same output shaft is basically hooked up to the transmission, or through to the transimission through a clutch. Well after some time, the round seal, it looks something like a flat donut, leaks. Imagine stretching a small spring around a shaft of steel and wrapping the spring in rubber. It will stop the oil from leaking along the shaft and out of the engine. After wear and tear, it needs to be replaced.

If this is the case, well, given that you have not said what type of vehicle you have, you would need to either pull the engine out or drop or pull out the transmission to get at the shaft and replace the $10 seal part. A lot of work for a small item but it will continue to leak until of course you run out of oil and ruin the motor.

I hope this helps somewhat.

1984 F150 302 Had oil pan gasket and both valve cover gaskets


you have several points to check!
the dip stick tube has a "O" ring seal at the bottom where it fits to tranny.
a reverse switch on tranny & the shifters selector shaft has a seal that may be leaking !
there are the cooler pipes from cooler to tranny [in & out] plus pump seal to the torque converter [leaks out between engine & tranny bellhousing] & then there are the drive shaft or shafts seals
so wipe it all clean & park it in a diffrent clean spot!
some will only leak when its runnung due to tranny,s internal pressure!

Loosing oil in 06 impala SS


First, do you see oil leaking on your driveway? Have you looked under the car and checked to see if any oil is dripping?A rear main seal will drip down the front cover plate of the transmission sometimes from the inside, appearing like a front seal leak on your transmission but the oil will not be red fluid you would expect if that were the case. I would not worry about rear main unless you see a leak there. Look your entire engine over and check for leaks everywhere. Several small leaks can add up to an overall large oil loss. Correct the larger ones first.
Generally all seals will last far longer if you change your oil frequently using a good quality lubricant. If you are loosing some oil, use one of the oils made for high mile engines. I suggest you use a mild additive like marvel oil 1pint with every oil change...it removes sludge, carbon and varnish buildup without the drawback of knocking it loose all at once, where it could plug up your oil pump screen. (it also smells good) Change oil every 3000 miles for the first three or four intervals, then consider using a good synthetic oil. Synthetics far outperform any other lubricant in every area! Avoid overheating your engine...overheating does more damage to seals than any single other item...When seals get very hot they harden up, crack and fail.
Good luck with your car!!!

Engine Rear Main Seal Leak


neither...rear main seal is broken do to the camshaft rubbing against it. Even fixing it with a new seal it will just leak again..best to just watch the oil lvl and add accordingly.
