Gearbox mounts

[Aleksander Mierzwa <alex@matrix.com.pl>]

Hi List!

Yesterday I decided to crawl under the car in an attempt to find the
cause of my idle vibration. First: two broken exhaust hangers. Second:
transmission mounts are not very bad, but the rubber shows signs of
cracking, so given they're not very expensive I'm gonna replace them.
There are two part numbers on each of them: one says SCHWARZ and the
other says BLAU. I'm confused here. What's the difference between
"black" and "blue" mounts and which ones should I get for my car? It's
and 87 5KT automatic. Also, although the engine mounts pass the "unbolt
them-try to push up" test, I get the impression that the engine is lower
than it should be. There's a rubber bush at the front of the engine that
isn't supported anywhere, there's a sign on the front crossmember
indicating that this bush used to touch it, but it's about half an inch
below now. Should it touch the crossmember or not? Any help will be
appreciated.
