M104 timing

[BrokenSockets]

Posted this on benzworld and got no response. They seem to be more interested in heated seat problems and discussing whether it's sacrilege to add a cup holder to 124's

Just did the head gasket on the E320 with M104.99. It's my first time doing a job this involved but everything is going well so far. Engine now seems to run OK with no oil leaks or coolant trouble but has a bit of what sounds like lifter noise.

With my 4 mm pins in and level, I am about 5 or 6 degrees past TDC according to the marks on the HB. Is this close enough or does it sound like it's 1 tooth off?

Should I pull the tensioner, top timing cover, lift the chain with the 4mm pins in position, turn the engine by hand to exactly TDC and re-lay it on the sprockets?

Just wondering here if 6 deg. at the crank sounds right for 1 tooth off and whether the variable valve timing is already capable of correcting for this amount of error. The cam adjuster was set to full retard before putting the chain on and re-installing the tensioner. Tension seems good

The marks I made on the chain and sprockets before disassembly are still lined up as are pre-exising marks that I see made by a previous person who must have been working on this engine. Could it have always been out a tooth and I didn't know it? It did run OK before the gasket failure, so I am wondering if I'm in about the right place already?
