VG30 Timing question

Thought u lot might be able to help. The following photos will explain a lot better, but with the timing on the crank at what I assume to be cyl1 TDC, the RH cam marking is where it should be, but the LH mark is almost a tooth off. I suspect this is due to taking around 10thou off both heads/block, but will this affect power at all? Should I redrill the cam drive pulley to line up?

Also the distributor when installed with the above markings lined up looks like this, look ok?

I think your cam sprockets might have gotten switched from the correct side. Switch them and see if it lines up better. Plus I remember after doing mine that they don't align dead on, they were very slightly off such as that.

Guys I thought I might add a followup to my question. I was quite worried about cam timing (justified or not) but either way nothing short of measuring it would satisfy me.

 

So, with my trusty dial gauge and a couple of extensions, I found that the final mark on the balancer is indeed exactly TDC of cylinder one, and then proceeded to fit and align a degree wheel to crank.

 

From there, I then fitted the dial gauge to the inlet and then exhaust lifters of cylinder one for the RHS cam, and cylinder four for the LHS cam.

This is due to the firing order of 1,2,3,4,5,6. Ie cylinder one and four are at TDC at exact same time.

 

You can just get the dial gauge onto each respective lifter barrel for true measurements.

 

Long story short, the measurements were pretty much dead on what they should be, with the lift on valve open/close on inlet/exhaust averaging .15mm when exactly on the factory specified crank degree for the VG30E camshafts.
