[Vwdiesel] 120000 mile service on my Jetta/ Needs for my Scirocco turbodiesel swap

[paulr]

Hayden,

Thanks for replying.

What was the the purple degreaser ("purple
stuff") you used?   Is it an industrial
grade chemical?

I don't think I've ever seen  anything
like that in  local auto part stores.

I'll look and see if there's something like
it in McMaster-Carr.   They seem to have
a pretty good collection of industrial
supplies  (1000+ page catalog...)


Thanks again,
Paul
