It's very possible that the gaskets weren't installed correctly. Unlinke other cars I've owned, my 99 A4's valve cover gaskets are actually somewhat longer than they need to be (about an inch or so), and you have to be very careful when installing them that they don't get pinched outside the "channel" that they're supposed to sit in. I'd be willing to bet that the installer bumped the gasket when replacing the valve cover and knocked it out just enough that it's allowing oil to leak past the gasket. I'd pull the valve covers again and verify that they're seated correctly. I would bet they aren't - there's really nowhere else on the 2.8 for the oil to leak where it could hit the manifold.

Oil leaking on exhaust manifold and smoking on 1998 nissan altima 2.4


You need to find out just were the oil is leaking from to start with .I have just done my Mercedes with the same problem valve cover gasket was leaking .Oil was leaking down the side and on the plugs that are hot ,, so it burns off the oil ,this is what you can smell. If other items are doing the same you will need to do that part as well..The breather system may be blocked up also if it is not breathing oil will build up . Good luck

When i turn on my 1983 buick regal it starts smoking from behind the motor some where and i cannot figure it out. what could it be?


Oil. if the smoke is coming from between the engine block and the firewall then its probably oil on the exhaust manifold. Make sure that your engine is not leaking oil from the seals and make sure the oil cap and dipstick are in place, start your car, with the hood up and observe the smoke if its bad then id take it to a mechanic but if its only mild then providing your engine isn't leaking oil it should burn off within a few minutes of the engine being started, i say watch the smoke because if it is leaking oil onto the exhaust in great amounts then it is possible it could catch fire.

Smoke coming from the left side of the engine


this may be due to an oil leak getting onto the manifold or the manifold is cracked and exhaust gas is building up in the engine.

if smoke is intence and black this indicates oil.
if it is mid and grey blue this indicates exhaust gas


get checked by a mechanic


i hope this was useful.

Since exhaust manifold covers engine block, I have


buy some engine oil dye at any auto parts store
a uv lamp will be needed to use to locate the leak
this works best with newer cars and so many things in the way

Burnt Oil Smell


Check carefully around the valve covers, this is the area that leaks most frequently occur, and being located next to the exhaust manifold can easily cause the burning smell. There is a very easy to replace gasket under the cover. Other possibilities, shop or you when changed or added oil spilled a bit and that has worked down to the exhaust manifold and is causing the burnt oil smell. Last possibility is that you do have a slow leak on the underside of the engine that is blowing back onto the exhaust system causing the smell.

Smoke comes from around engine


Probably a vavle cover gasket leak, small but enought to produce oil, in or on the surface of the motor doesnt take much to a lil smoke from aa hot engine...it could be collectiing in the canals ontop of the motor where the vlave covers sit on the head? or a head gasket problem....inspect it well after you run the car for a lil while, b4 it starts to smoke
