Is this the same place as www.vwdieselparts.com? Surprising, as I've perused his site several
times over the years, and he seems to know diesels well. I've heard the odd good comment about
him, but none bad until now.
Anyway, here's the specs from my 85-92 Jetta Bentley:
Exhaust manifold to cylinder head: 18 ft lb
Oil supply line to turbo/return line to oilpan/return line flange on turbo: 22 ft lb
(I mention these because I've had leaks at both return line junctions on mine before)
Exhaust pipe to turbo(nut): 18 ft lb
Turbo to exhaust manifold (12pt bolt with high temp anti-seize): 33 ft lb
Those turbos are more forgiving than you might think: when I did my headgasket a few years
back, I re-installed the oil supply line to the turbo but forgot to remove the rubber plug I had
installed, which somehow managed escape my notice. I drove the car several miles before the
turbo started to act and sound strange. I then remembered the plug, and in a panic reassembled it
all without the plug, and ran the engine, expected to find a seized turbo... but it ran fine, and has
ever since. It still amazes me that it survived such abuse! (now at ~280k km on this engine).
Good luck!
