So I'm leaning towards negotiating this car to buy it.
Question, the PPI revealed a possible stuck distributor advance. The symptoms are terrible high boost pinging and cutting in and out. Boost comes on fine but then bucks and pings (bit of smoke out the back on high boost)
How easy is it to rebuild or perhaps free up the distributor and the advance mechanism? Can I do this myself?
If I get the car I will do a full service, machine the rotors, flush out the brake fluid and put a heavier weight oil in 20W50. Drive it for a bit and see what happens.
The rear wheels bearing(s) are making noise. How big of a deal is it to change them? Why is it expensive? Can I do it myself? Only wheels bearing I did was on my Mercedes 300SD, I paid $20 for a machine shop to press in a new race and carefully following internet instructions of not over tightening the bearing hold down ended with a great result

. 25,000km later and still works a treat. $50 all in.
