You may remember that my car failed its MOT in May because of excessive smoke on idle and heavy acceleration. I changed the PCV valves and 34 of the pipes and all seemed OK and it passed its MOT.

 

Well over the last few weeks I have noticed a smoke again after idling for 5 minutes or more. After about 10 minutes of idling the smoke stops though.

 

When I installed the valves, I noticed that there was no spring pushing the ball bearing out, it moved freely when shaken. I though this odd until I looked at the pipes and their appeared to be something metal in two of the pipes, so assumed these were valves.

 

Have I installed the wrong valves or maybe put the pipes in the wrong way round?

Did you buy the full pcv set ?

 

My pcv valves rattle too, the small metal bits in the pipes

are just a restrictor as far as I know, but the hoses that

connect to the actual valves don't have a restrictor on mine!

 

Only the pcv pipes at the back have restrictors in them.

I did buy a full set. I thought I had matched the pipes (going on length and shape) but would have been easy to put the wrong pipes in the wrong places!

 

I keep seeing oil catchers on ebay. Are these any good / going to help stop the smoke ?

The pcv valve ball bearing should rattle,if its silent when shook then its no good.If the car still smokes then id say it was time to get your wallet out.You done many miles since you changed them? allow 500 to clear the oil residue out.Generally any idling smoke is Turbo related im afraid though.So brace yerself.

If that is the case Jimmer what are the cost implications? Not sure if it's just the colder weather/paranoia but think there is a slight chance mine are on the way out.

are you sure it's smoke and not steam? mine bellows steam out on cold days like these days...
