Reply to "VG33E V6 Timing Belt Replacement"

There are marks on the new belts that you line up with the dimples on the camshaft gears... that plus getting the correct number of teeth between the gears (40 between the camshaft gears as you said, and 43 between the RH camshaft gear and the crankshaft gear) takes care of it (so you don't need to really worry about those marks on the timing belt cover.

Everyone should replace the little bypass water hose while they are doing this job. It is nearly impossible to get to without tearing everything apart and removing the rear timing belt cover.

The hose (note: we had to put the upper clamp on the other way so the screw piece was back behind after taking this pic because it hit the rear timing belt cover):


How did you pry out the camshaft seals (do they just pop right off)? I had new seals - but I didn't want to get in a situation where I couldn't get the old ones off but I'd messed them up trying... and since the old ones weren't leaking I just left 'em.

Nice writeup!

Also - there are several different sizes of timing belt cover bolts and if you don't pay attention when taking them off (or look very carefully at the FSM) you'll have a hell of a time getting the right ones back in the right holes (And several people I know have messed up putting that bottom smallest one on and have had various problems because of it... Nissannut's motor threw sparks at his first startup after the change because the wrong bolt was in there and it was hitting the balancer).

I took the super-anal route and printed out the pic from the FSM - and then put each bolt on the pic as I took it off - so each bolt went back EXACTLY where it came from.
