GRUMPY??
Is TDC of CYLINDER #1 = to BDC of #6 CYL?
btw when checking for TDC its usually best to pull all the plugs it makes spinning the engine by hand FAR easier
NO! YOUR NOT CORRECT!!
tdc on #1 on the compression stroke =TDC on #6 on the exhaust stroke
the #6 and #1 piston would be at TDC atTHE SAME TIME
keep in mind that the cylinder banks are 90 degrees apart so for #1 and #6 to reach TDC at the same time that requires the crank throws on those two to be separated by 90 degrees
I just went out to the shop and played with one of my engines, the more I thought the more confused I got even thought about it the more confused I seemed to get ,Id done this thousands of times, but TDC on #1 is the same on #6, simply turning the engine over and watching the pistons confirmed that , the confusion is that while #1 is at TDC on the power stroke #6 is at tdc on the exhaust stroke
firing order 1,8,4,3,6,5,7,2
if you care the order the pairs of cylinders reach TDC, at the same time in the block are.....
1-6
8-5
4-7
3-2
"remember the cylinder banks are 90 degrees apart and one of each pair is on the compression stroke while its partner is on the exhaust stroke"
TIME TO GET OUT THE DEGREE WHEEL
