This guitar string is just under 1mm and stops in both spots shown. It fits freely around the rest of the VVT gear.

The LH side runout is .009 in. The spec wants .006.

The same 1mm guitar string gets tight at the high spot, but will pass. Fits freely round the rest of it.

Both VVT gears have a date code of 11H28 which translates to Nov. 28, 2006. I guess they’re both original after all.

The LH side appears to lube better than the RH side. Manually rotating the crank picks up oil on the LH, but not so much on the RH. Might explain why it looks much better on the left.

I’ve decided to replace both VVT gears based on the runout. That’ll stall the job for a bit.

My cordless impact was enough to spin the crank bolt loose.

Had to take off the alternator and bracket to get to one cover bolt.

The primary chains and tensioners look ok.

Remove the crank sensor.


Rotate the crank until the special hole is inline, not the square holes.


It’s rounded on the in and out edges.


Insert the special crank locking tool. This was a pretty snug fit. The mounting hole is a bit off center so I couldn’t lock it down, but it won’t move. Cheap tools.

RH cams are locked.


LH cams are locked. Had to re-drill cam holder holes on one tool. The holes were a hair off and wouldn’t fit right. Didn’t take much. The bolts were too long also so I used some spacers. Cheap tools.
