G'day Driv3r.
Your best bet may be to find someone familiar with the 5cyl motor, transporter or R5. My couplings were done at about 140k on my R5, but my alt coupling failed on my T5 a few years back. The coupling would spin. VW wanted to pull the motor till I got in touch with a guy in Nowra to change it.
Which oil and how much was it? My last oil was from VW. 10l for $80 because it was 'out of date'.
