    ok. i started driving my old 6.2 about 3 years ago. at that time it smoked just a little when it was cold. over the years it finnaly got to where it smoked nasty black/blue oil burning smoke that left soot everywhere and burned my eyes. so when i got my new motor and it was still in the donor truck it did not smoke at all. not even on cold starts. its been about 2000 miles now and she smokes a little when cold. then last night i noticed that ideling in a parking lot, at running temp, was smoking just a little. i got down on my knees and gave it a sniff and it was the same burning oil smell. what the hell am i doing wrong? did i mess up this motor too? please give mer some help. i am using chevron delo 400 oil. it has new oil and fuel filters.

    I think you're in a panic over nothing. They don't call diesel engines "oil burners" for no reason. Diesel fuel is more like oil and is nearly the same as fuel oil used for heating homes. Diesel engines will burn anything oily, like ATF, engine oil, vegetable oil, etc. The smell is normal. Your old engine may have been worn out, making the smell and smoke more noticable. Your new one is tighter, and of course you're going to get the smell if you're sniffing down at the exhaust pipe. Relax.

    All diesels smoke. It's normal. Mine puffs a little smoke when idling.

    I've had two 6.2's. I've heard that they don't take well to synthetic oil. I use Rotella T and have never had a problem. You need to change the oil every 3500 miles and you can notice the difference when you drive after a fresh oil change. These engines have character /forums/images/graemlins/tongue.gif
