My 90 200tdi needs attention again!!
I need to clean / de-grease my gearbox and transferbox (while in situ
with tunnel and seat bases removed for ease) because its smells after
a while on long runs. I figure once ive changed all offending gaskets
and seals this should stop the smell (and drips!).
Ive heard about "gunk" but never used it and also read about the
DIFFLOCK product. Which of these is best and are there any others I
should go for???
