Grayish-white exhaust smoke...

Now that the oil is changed (finally), I fired ol Project Mayhem up for a couple of mins. after I turned her off there was this smoke slowly lingering out of the tailpipes for 5-6 mins. It had done this b4 the oil change. When running, she smells like a lawnmower. Pretty rank. The grayish-white smoke comes out during runtime as well... What do yall think Im dealing with here?
Worn rings? Engine runs smooth as silk and very quiet... Hmmmm

The pics show the pass. side tailpipe after engine is off... You can kinda see the smoke lingering out of there...

Re: Grayish-white exhaust smoke...

Have you noticed a loss of coolant? If so it could be coolant entering a cylinder and making it's way into the muffler. Take the radiator cap off and start the engine, if you notice bubbles in the coolant you probably have a blown head gasket or worse cracked head or block. These are worst case scenario, it may be nothing to worry about... When you say it "smells like a lawnmower" do you mean it smells like unburned fuel, sounds like it needs a tune up? Good luck.

Re: Grayish-white exhaust smoke...

If it is white it is water, if it is blue-ish it is oil. If you think it is the oil, you can run Lucas oil treatment. I had a friend with a diesel that was having blue smoke. I added the Lucas to his truck about 3 yrs ago and he has had no problems with it since.

Re: Grayish-white exhaust smoke...

if it's pumping out white smoke while you're driving down the road after it's all warmed up, you've got water entering one or more of your combustion chambers like the previous poster stated... check your dipstick for chocolate milk.

think of it as getting your exhaust system steam cleaned for free...

Re: Grayish-white exhaust smoke...

if you're only running for a few minutes chances are it's just the engine burning of the condensation inside the exhaust and cylinders fron sitting// also in some areas gas companies have additives that will cause this type of smoke// best is a long run over the road to get to operating temp
