I have read various posts regarding reseting timing etc but cant seem to find anything that specifically deals with this issue...
I have been told that as my engine is the early non vario cam type that I merely need to get the engine to TDC and lock it there. No need for the cams to be locked...
Firstly, can anyone confirm this? and secondly, when told to put engine at TDC does this need to be compression on bank 1-3 or do I simply turn crankshaft pulley until mark lines up and lock?
hoping some kind soul can start my new year of with a solution...

Even though your engine is an early 5 chain, you still need to manually rotate it to TDC (turning it clockwise only) and then insert the locking pin through the pulley and into the boss on the engine case. TDC is the only position where all of the cam lobes are unloaded, reducing the chance for timing jumps while working on the tensioners. I would also install a cam locking tool on bank 1 to eliminate any possibility of cam movement.
You can then remove the leaking tensioner and replace the crush washer.
