Expert: Ron Wolff Date: 2/22/2007 Subject: Sludge in crank case
Question I changed oil today on my 97 jetta 2.o liter (175000 miles) and noticed a grey sludge around the inside top of the crank case and on the underside of the oil cap. I could run my finger along the underside by the fill cap and scoop this sludge off. What could be causing that?
Thanks
Todd
Answer Hi Todd,
Gray sludge is usually a sign of water. This could be caused by something as simple as a dirty PCV valve and infrequent oil changes.
The worst case scenario would be a leaking headgasket. This can usually be detected by white exhaust smoke while accelerating and oil residue in the antifreeze.
