So I am about to swap in my 'new' 2.0 liter inline gas block (93 Jetta
ABA) into my 84 with a diesel 5sp.  I am almost done gathering parts to try
to anticipate possible need and minimize down time during the change over.
I have a leak in my old 92 1.8liter inline gasser  set up...the rear main
seal, I guess, and my clutch seems to chatter a bit sometimes.  So I thought
I might consider installing a new pressure plate, at least, during my swap.
   Can I just order up a pressure plate to install after cleaning the other
parts up really well?  Probably replace the throw out bearing too?  Or
should I just leave it alone and avoid some unanticipated extra expense and
time.?  Am I talking a lot of work and time and possible "gottchas" with
this clutch change as I install the new motor?
   I am thinking my current clutch may be slightly contaminated from the
leaky rear main and it is probably a bit thin from me using 2nd gear (of my
5sp) to start from a stop most of the time...Since I am in there, I thought
the change might be a good thing.  It is still working OK, it only chatters
if I do a ham-footed Jackrabbit start so it 'ain't broke' really...just
tired...I don't want to have to surface the flywheel...nearest machine shop
(that I really would trust) is in Portland...a few hours away..

  anyone thoughts?
