I'm brand new to the forum and searched high and low for a post/thread with this issue. Have an '03 Silverado LB7 with 67K miles. Recently began noticing occasional white smoke from exhaust at random times...normally under moderate load. The other day I was dropping off my 5th wheel and the truck was idling for about 20 mins while I unhooked and secured the trailer. Took a slow idle out of the lot and on moderate acceleration out onto the road a fairly thick cloud of white emitted. I accelerated pretty close to full throttle and it cleared up after a very short 10 seconds or so under full load. Have a check engine light on now and a friend told me to check for fuel in the oil because he'd heard that from somebody else. To my surprise the dipstick is above full by about 1/4 to 1/2 inch...smells, but then, I don't know how strong it's supposed to smell. Not exactly like diesel fuel, but then I don't know what the regular oil normally smells like....just oil I thought...almost odorless. This is definitely stronger than just motor oil, but then it's been about 2K since my last change and I don't normally check the smell of the oil.
Sorry for not finding this if it's obvious to those who know....but now I don't want to drive the truck if I've got thinned oil and may be damaging bearings or something. Any thoughts/advice/experience would be HUGE for me.
