[Vwdiesel] PD cam failure & Guttless Jett

[brian gochnauer]

I have the electronic version of a bently called eBahn manuals for the Jetta
and Golf from 1999-2009 covering both gass and diesel engines. This means I
can "print-to-a-file" and send you information, but I'm not sure what your
looking for.

If the cam lobes and followers are smooth and there is no, what looks like
 'cracking'  of the contact surfaces.
The first stage is discoloring (some is normal) then has it gets darker gray
you'll see the cracking start to form as is breaks through surface hardening
of the camshaft lobes and followers (lifters). The cracking is actually not
cracks but small flakes of the surface coming off in an irregular pattern.
Once one side (camshaft lobe) or the other (follower/lifter) starts to fail
(crackling) the time to complete failure will not be very long, probably
less than 5k miles.

You'd have to carefully inspect the cam for surface crackling as well as the
followers, with both installed you can't really get a good look them. You
could probably check the camshaft, as it can be rotated and inspected by
hand turning the engine.

I guess I don't have your complete story but the '04 Jetta w/BEW engine is
not what you'd call 'quick' by most standards.
And the tranny ratios are different in gas and diesel engines.

Let me know if you need specific 'printed' info from the manual.
