100K and a little smoke on startup

[rtbrick]

I just turned over 100K on my 2000 Z71. I have to say that at 6 years old, that many miles and the minor wear and tear...I still like my truck better than most others. It rides great, not had many problems and I really like the styling. That said, I recently noticed a little blue/black/gray smoke on startup. Oil issue. Haven't really noticed it once the truck has been driven or warmed up. I need some advice on what the problem may be and, of course, the solution. I'm thinking it could be valve seals, maybe worn piston rings, but I am no expert with todays engines. It's probably gizmo #4 located on the bottom of the top of the middle of the whatchamacallit. All advice is apprecited.

If it is on startup after the vehicle has sat a while, then it sounds like valve stem seals.

I would also suggest valve seals. Todays engines are no different than the older days. In the end it is still an internal combustion engine, all the same principles.

What kind of Oil are you running? 102,000 miles and no smoke on start up, but plenty of other problems. Engine seems fine, it's all the stupid electrical sensors and drive train crap thats going bad.

Dear sir,

 

You have no problem. enjoy your truck! Every engineering text book states that a certain oil consumption is normal.

 

ENJOY YOUR TRUCK AND STOP LOOKING AT TINY BITS OF START-UP SMOKE!!!

Just be glad your not driving a Chrysler product. Seems like they are the most prone to smoking at over 85,000 miles! I am seeing ALOT of Newer model Intrepids smoking, reminds me of the old 84-95 Dodge Caravans/Voyagers with the Mitsubishi 3.0 Litre engine, which would smoke like crazy after 90,000 miles.

Praise the lord and pass the ammunition!! Every engine known to man is going to burn a little oil here and there. I'm an aircraft mechanic and the turboprop motors we run have a burn limit of 1/3 gallon...not quart...per hour. Don't worry...be happy and enjoy the nice truck you have .

Gents,

Thanks for the advice and piece of mind. I' ve used Mobil 1 since about the second oil change and usually go through two oil change lights before I change the oil. The smoke is new, so I was worried. Other than a few usual irritations (lights out in the climate control and radio, a little engine rattle) the truck is great. I'm anal about keeping it clean and nice, so most folks don't believe the mileage or age when I tell them. I'm waiting to see what the 2007's look like. I really like the new Tahoes, so if the Silverado design follows suit I may look at trading in '08 (never trade for a first year design, right?). The only thing my current truck does not have that I really want is four full doors.
