Hi Guys! <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />
I have a 2002 Silverado with 5.3 engine. My truck smokes if you let it idle two or three minutes and blip the throttle. <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

I have told you all about this before. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I decided to do some investigating. <img border="0" alt="[whiner]" title="" src="graemlins/gr_cry.gif" /> I put a clear inline filter in line with my PVC Valve and lots of oil is being sucked into my intake.

I have the Updated PVC Valve! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> QUESTION: How long would it take for the oil to dry out of my intake so my truck won't smoke. I have unhooked the PVC Valve to see if it will stop smoking.

CAN oil puddle in the intake and stay for a long time or what? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

If this doesn't stop the smoking then It must be valve stem seals or valve guides.

Thanks Lee! Please let me know! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

Lee, what has the dealer said about this? How much smoke? If you can see oil vivsably being sucked into tthe intake, then you have a larger problem than the PCV. The factory PCV is junk anyway. You may need to try a high performance one if you can find one and make it fit. The oil in the intake should not puddle. It could be the valve stem seals, but I just havent heard that one on the new trucks before. I know you have heard it before, but I would take it back to the dealer and insist that they fix this problem. Sorry, I'm not much help for you but unless you have taken the cats out, that just sounds like mechanical failer. I wonder if it could be blowby in the cylinders. Hope not. Didin't you say it was using 1qt every 3k? GM will say that is normal, but blue smoke certainly is not. Take it to an emmisions testing facility, let them test is and it shoud fail. Then go back to GM and let them see it. Then they will have to fix it.
