Exhaust valve - Number 1 - Number 2 - Number 3 - Number 4
Lash = _________0.23_______0.20_______0.22_______0.28
Shim = _________2.75_______2.72_______2.76_______2.66
Total = _________2.98______2.92_______2.98_______2.94
Intake valve - Number 5 - Number 6 - Number 7 - Number 8
Lash = _________0.21_______0.20_______0.18_______0.20
Shim = _________2.75_______2.74_______2.70_______2.80
Total = _________2.96______2.94_______2.88_______3.00
Exhaust valve - Number 1 - Number 2 - Number 3 - Number 4
_____________2.725_____2.665_____2.725______2.685
Intake valve - Number 5 - Number 6 - Number 7 - Number 8
_____________2.765_____2.745_____2.685______2.805
With rounding, I need:
Exhaust valve - Number 1 - Number 2 - Number 3 - Number 4
_____________2.725_____2.675_____2.725______2.675
Intake valve - Number 5 - Number 6 - Number 7 - Number 8
_____________2.775_____2.75_____2.675______2.80
Thus, the shim from valve 2 will go to valve 1, the shim from valve 4 will go to valve 2, valves 5, 6, and 8 will remain untouched. I need to order the shims for valves 3, 4, and 7.
Here is one small issue I have though. I'm about 90% confident in these measurements. However, I was able to read/infer some of the markings, and my shim measurements don't jive with the marks on some of the shims.
Is it possible for shims to suffer wear and become slightly thinner? The differences I saw were on the order of 0.1mm. I'm not entirely sure if this is due to some systemic error in my digital thickness gauge or due to wear. That said, I did verify its correct functionality against my feeler gauges. It is dependent on positioning/movement, but with the gauges, I was close to spot-on.
I would hate the order the shims, wait 2 days, install them, only to find my valve clearances are not what I intended to put.
