my 2001 truck puffs smoke at start up or whenever i step on the gas hard. valve seals ? Plenum gasket? or rings ? what do you think ?
thank you

 

Just a puff at startup is usually valve seals. If you have oil consumption issues, that's gonna be the plenum, and possibly PCV valve. (along with rings, but, that's expensive, so we won't talk about that. compression test will tell there.)

Check out the Plenum thread in the 2nd gen section.

Welcome to DF!

 

If the smoke under hard acceleration is very pale blue like oil smoke, try changing the PCV valve with one from the dealership.

For the rest, pay attention to that HeyYou guy. He's pretty smart for a guy who drives a Dodge.

 

thanks guys going to change pvc this week after that ill try the plenum plate and gasket.

 

i just changed my pvc in a 5.9 2001 gas, i was using a quart to about 50 miles, and now it doesnt use oil or smoke. but the trans wont shift fron 2--3 by itself now, lol

 

Taking the throttle body off and not reinstalling the throttle kickdown cable correctly will cause this. been there done that!

 

Try the PDF in this thread. I had the same problem when I just reassembled my truck and this fixed it. * are "dodge talk" one word

changed the pcv vavle value cover gaskets and plenum gasket yesterday 80% back together , the pcv is on the driver side valve cover what is the one on the passenger side called . i dont think its a pcv valve jsut a elbow of sorts . i broke mine while uninstalling it . intake was full with oil .
thanks for all the advice guys .

 

Yep, it's just an elbow. NAPA calls it a "PCV System Elbow", P/N NOE 6301078, and it's less than five bucks. You should be able to find the official Chrysler nomenclature and part number in the appropriate parts manual, which is a handy thing to have on hand.

 

well, got it all back together, still smokes a little but. check oil after a long ride didn't seem like it was burning any . might just be whats left in the exhaust system etc, burning off. we will see.
