[Vwdiesel] Signs of PD worn cam syndrome?

[Shawn Wright]

Interesting thought.

I just found out the '04 I'm looking at also has a suspected turbo seal
leak, which could explain the oil in the intake plumbing. It was documented
in Dec 09, but the dealer chose not to fix it, likely due to the 250 labour
+ 700-1400 for rebuilt turbo quoted. I assume it just needs a bearing & seal
kit (I've done two of these before on 1.6TDs), but again, it's more work I
don't really want to get into...

Time to move on I think.
