VW 1.8T engine sludge
VW 1.8T engine sludge
(OP)
thread89-141793 Some engines are prone to making sludge. It is in the design. It seems to be in the PCV system design. What appears to happens the oil oxidizes, turns to sludge and can't be pumped, therefore failing the engine. Best solution is to use synthetic oil and change often. The important thing is to change often. I've known engines that missed a 3k mile oil change and failed.





RE: VW 1.8T engine sludge
My assumption was high head temp differentials, low overall volume and long change intervals combined to make the prob.
I had a 1.8T in a 2000 Passat and it developed sludge. I ran synth and did my own changes every 5,000 miles. (You would think I'd know better). At 70,000 miles I had to drop the oil pan and scrape the junk out because it was clogging the pump screen.
Strangely my German freinds have never had this problem on their 1.8Ts.
