Yeah that's a good point.
Do the exhaust valve seals show the same symptoms as the intake valve seals.

Pedro, found this

Pull the tube off the turbo's outlet. Once you see that it's not caked in oil, you can put this "oh it must be the turbo" issue to rest.

Then continue on to change your valve stem seals.

Jesus, I go back to work and you guys went off lol



As stated I've replaced the PCV valve. However, I'll get one of those filters on there this weekend and see how the car reacts.



I shall keep this in mind after I try the filter, although Alex had a nice blue shiny one I might go for instead



Thanks Bryan, that's the same article I was reading on yesterday:)



you make it sound oh so easy. I'll take a look at the turbo once more before continuing on to change the valve seals.

yes take mine!!!

Not true at all.

Gonna need to pull off the O2 housing (and ideally the turbine housing) to put that to rest. My 14b was completely clean on the cold side but burned oil on the hotside. If I took off my O2 housing (and moreso, the actual turbine housing) I could see the remains of burnt oil and it was wet around the edges of the 'seal' on the hot side.

But change the valve seals first .. they should be changed anyway. It prolly is the problem. Also open your crank case vents to the atmosphere... your only saving the enviroment with them. But if the problem still exist.. look for another turbo. Dont even waste your time with the 25.. You should be upgrading anyway.And if that dosent fix the problem... Theres plenty of spare blocks kiking around for rebiulds.

"I'm blowing a bit of white/blue smoke when I move from a stop or when I idle for more than 5 minutes. The smoke is from burning oil. When I drive I do NOT see any smoke behind me while cruising or under boost"

You haven't seen sh!t enough valve stem seals NOT to leak at idle. I doubt it's a turbo from Pedro's description.

valve stems can leak at idle... but not bad enough to make clouds of smoke behind the car. He saysvit happens at 4000rpms aswell. which means that there is alot more air going thru the system the oil leaking thru the seals. Warn turbo seals... or even bad vetalation and high crank case pressure will push oil the turbo seals at acceleration and high rpms.

Ive seen sh!t lots of leaky valve seals. My dads jimmy fills the drive way with smoke when he starts it up... Cause the oil leaked into the cylinders and puddled on the pistons. Dosent smoke after that. Not enough to notice. As soon as I put the littlest amount of load on my trubo saturn it would smoke... bad turbo.. same as my last 16g.. wouldnt smoke unless I gave it some rpms.and when It was cranking over.

It WILL make a steady blue trail of smoke coming out of the exhaust at idle. Every engine is different and just cause your dad's jimmy didn't smoke at idle doesn't mean they don't... Also I've re-read the thread and never saw him saying anything about 4,000 rpm's?

But seriously.... wh are you challanging me??? He asked us what we think. This is what I think.... its not wrong. I agree that it could be the seals. but I added that it could be the turbo. As it very well could be. I dont know where my added advise needed to be ridiculed?? My dads jimmy is an example of realy worn seals not smoking during idle or light criuse. Ive been rebiulding motors for 20 years now. Ive delt with a few oil burners. Were trying to help the OP fix his car not argue with each other about simple opinions. Thats what Tuners is for. Are you drunk and in a bad mood? You sound like 2 people I know on here already..lol.

Woah. Don't take everything to heart lmao. Don't cry about me doubting you as I could be wrong as well. Just trying to save this guy extra work. 1+ for the internet How much smoke comes out at 4k+ and till what rpm Pedro?

Sorry.. guess I was a bit grumpy after taking a day off of work to rebiuld my TB and redo my coolant system ... just for a dissapointing drag night and the evasion being cancled.

It was one time. It was a puff and I was in 1st. I did the seafoam treatment and went for a rip and saw no smoke at all and I was doing over 4k in 2nd and 3rd. Terry came with me and was looking for smoke and saw none every time. Sorry posting that misleading part and not updating

Thanks for all the help guys
