For the record, this concludes (for now) like this: Got the work done by Dave Jeffrey at Auto Shop on Haas street in Toronto. I mention the name of the shop because I felt that Dave knew the work very well. Talked like Haynes, grumpy like Condelli — must be an experienced and learn’ed Vanagon mechanic. New: -flywheel seal -gearbox oring -clutch kit -machines flywheel -new slave cylinder (he broke it off during disassembly cuz the nut was seized) -robusticized my oil pressure gauge system by using brake line to move the Condelli “TEE” assembly to above the engine. (I know, my oil pressure will be pessimistic by a half psi. No biggie. ) -purged brake lines (back two only; fittings at the front were seized) -new (hole-free) tail pipe. 14.25 hours labour. I think that was about it. Comments? I still don’t have a Dennis Haynes hitch, but there is always next year.
