Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
I have a 1994 VR with 290K on the clock. I agree with Danny. So far I have replaced:
-transmission ($1,300)
-front wheel hubs ($500)
- belt tensioner
- water pump
- fuel pump
- front engine mounts
- various rubber bushes (stabilizer bars, panhard rod etc)
- fuel pressure regulator
- radiator
- other wear & ter stuff (brake pads, exhaust pipes, filters, plugs. HT cables etc)
I've learn to live with oil leaks - too $$$ to fix.
this list is EXACTLY what ive had to spend on mine....and now im up for a new K-Frame...but thats not really a common fault
