I have a 94 3.4 A4. I noticed the other day, that when I turn it on, a cloud of blue smoke came out, then would stop. I would go in reverse up my driveway and I could see it coming out. Couldn't tell when I was driving if it was coming out or not. I had someone rev it up a good couple times and some came out around 3,000 rpm. But then today it didn't smoke at all. Do any of you know what that could have been from?

Blue smoke? Sounds like you're burning oil. Maybe your piston rings are worn down?--<b>David</b>--<br /><a href=\"http://bryant2.bryant.edu/~dsantore/index.htm\" target=\"_blank\">The <b>NEW</b> V6Bird Website!</a> <br /><a href=\"http://members.cardomain.com/thev6bird\" target=\"_blank\">Cardomain site</a><br />ΔX -
Well I only have 47,000 miles on it. Would they be worn that quickly?2003 Nissan 350Z Touring Coupe, Daytona Blue, Frost leather interior, navigation, 18 inch wheels, M6, fully loaded, intake, crank pulley.<br /><br />Previous cars:<br />1991 Mustang (347)<br />2002 RS Camaro<br />1985 IROC-Z (305)<br />1994 Camaro convertible V6Comment

It's oil, but probably not the rings. I vote for valve guides. First check the oil level, make sure it's not overfull. If all is well, go to the auto parts store and buy a bottle of Bardahl's No-Smoke. It basically just thickens up the oil viscosity, but it works really well. Either that or replace your valve guides. :rolleyes:\'94 Camaro 3.4<br />\"No, Starvin Marvin. That\'s my pot pie.\"Comment

Well I did check the oil to see if water was in it, but there wasn't. It was a little over full. Maybe that was it. But I had it changed this morning so maybe it will be ok now. It didn't do it since so maybe everything is ok.2003 Nissan 350Z Touring Coupe, Daytona Blue, Frost leather interior, navigation, 18 inch wheels, M6, fully loaded, intake, crank pulley.<br /><br />Previous cars:<br />1991 Mustang (347)<br />2002 RS Camaro<br />1985 IROC-Z (305)<br />1994 Camaro convertible V6Comment

<blockquote>quote:</font><hr>Originally posted by Red94Camaro:

If you were burning oil due to overfilling, it gets sucked into the throttle body from there.\'94 Camaro 3.4<br />\"No, Starvin Marvin. That\'s my pot pie.\"Comment

I would definatly vote for the valve seals. Your car is getting older, and has very few miles for how old it is and there may have been periods that the seals didn't have oil on them and may have weathered some. I have also heard of some oils a while back causing the seals to deteriorate. Try high milage oil. I have heard good comments on it so far, I am going to switch to it with my next oil change.1995 Firebird 3.8 A4, 140,000 miles and going strong<br />Basically Stock, college=poor <p>Junior Mechanical Engineering Student: Milwaukee School of Engineering; Cpl, MN Army National Guard...just got promoted :)Comment

There are various sealant products out there, but call me old fashion, when my 460 v-8 and 350 v-8 had a little blue smoke as they grew in age, I went from a 10w-40 to a 20w-50, and STP oil treatment which solved the problem.
For a v6, maybe a 10w-40 with STP oil treatment will help.
Anyways, that I what I used back in the day...
Just a suggestion...

I did the same with my old 350, and I guess for my 250,000 mile escort. I just jumped weight. 10w-40 and 20w-50 in that escort. Cold starts can be a ***** but that awful knocking sound it gets when I beat on it goes away.1995 Firebird 3.8 A4, 140,000 miles and going strong<br />Basically Stock, college=poor <p>Junior Mechanical Engineering Student: Milwaukee School of Engineering; Cpl, MN Army National Guard...just got promoted :)Comment
