well, ever since ive got the GL running.. it's made a noise of which im not sure its the TOD or a rod knock or a bearing problem... it seems to go away the higher the RPMs are and sounds like it's all over the place, not just in one cylinder. the car had sat for 2 years, prior to me buying it, and i changed the oil to 10/30 and substituted a quart with MMO.

 

Also... this may be related to the noises im getting... i changed the oil 150 miles ago, and had lost one quart already... and also, one day i drove it approx. 40 miles and came home, it was smoking badly from under the hood, in the back of the engine compartment, behind the cat converter all over the exhaust pipes causing the smoke. I havent lost any coolant, tranny fluid, gear oil, or anything else.

 

What's back that far that oil could get through? Or am I missing something? The oil does not leak out of the front whatsoever, and it doesnt burn oil at all. No puddles on the ground, either.

 

Feedback is appreciated... this will be one of the last things I need to diagnose before my Zion National Park trip..

Have you checked the power steering fluid? I know my loyale has a small leak underneath but a slightly faster one might be enough to spread the fluid to the exhaust.

i dont even think my power steering is connected... i filled it with ATF and it loses it like nothing. Plus when I do fill it, it doesnt even register with the steering. do the power steering hoses run by the exhaust?

 

plus that doesnt make up for the loss of a quart of oil in 150 miles...

Oil leaking from the engine can blow back on the exhaust like that. But then, you should see the oil on the bottom of the engine and/or on the ground....

try 5w/30 oil? wont fix leak but may help slow pump get rid of engine noise at lower rpms.

Mine turned out to be a hairline crack in a valve cover that was just about invisible -- except when the engine was hot and oil pressure was high, at which time it opened up enough to be dripping steadily, losing a quart in 300 miles.
