Sorry. Gotta jump in here. The intermediate shaft on a '92 Jetta engine
does not get driven off the back side of the timing belt! If this were
the case the engine would never run, as the distributor is also driven
by this shaft. It is driven by a "toothed" pulley. The only thing
"driven" by the back side of the belt is the tension adjustment pulley.
I've just put mine back together so I am familiar with what is doing
what. Don't look for oil pressure problems here. The pump could be bad
but it isn't because of belt "slippage." Just trying to clarify a
misconception before it becomes a rumor.
Tiico project in progress.
