I changed the turbo inmy 2.3 saab a year ago I did not change my scan tech pcv valve, and I changed the pcv kit new that the dealer told me to upgrade with the new kit, I now have white smoke coming from pcv valve out from the valve cover and just changed the scan tech valve the rest of the pistons have 200% compression. Do I now have sludge build up and what do u think maybe damaged, or what may be the problem

Hi there, if you haver a low compression, do a wet compression test, add about 2 tea spoons of oil to the cyl and re test, this will temp seal the ring lands and if there is no reasonable improvement in comp you will have a vale problem, also get a heads check done this is a simple chemical test to check for exhaust gasses in the cooling system.
