PCV VALVES??? :confused: :confused:

PCV VALVES??? :confused: :confused:

is that from cold start or all the time!

only cold engine and low idle greg

only cold engine and low idle greg

sounds like valve stem oil seals,if only from cold start,what happens is once engine warms up they seat better hence why it may only smoke from cold

 

if you have replaced all the pcvs and related hoses,then you can rule that out,for the cost of replacement its always worth to do that first!

 

do you get any/much smoke on boost ?once car is warm

no greg in wot nothing of smoke

if you have chaned the pcv systym,then do a comp test and make sure all cylinders are within spec,also check oil leves are ok,and your not burning or loosing oil

 

this isn't 100% accurate but these are general signs for differant problems

 

blue smoke with boost [pcv or turbo]

blue smoke from cold start[valve stem or rings]

continuous blue smoke,sometimes severe[damaged ring lands,rings,pistons]
