Leak Down Test Question

Leak Down Test Question
Figured this is the best area for this cuz LDTs tend to be a FI Diagnostic tool.
Ok---Left Bank is 2-4-6 Right Bank is 1-3-5 Firing order is 1-2-3-4-5-6.
TDC (compression) is for #1. Are there any more that are at TDC at that time ???
Engine Pulley is rotated CW----How many degrees of rotation to get the next set up TDC? ETC ETC
Trying to save some time and I may just be brain locked
Thanks Guys

An easy way to determine when an individual piston is at top is to put a rod down the spark plug tube and rotate the engine then once you see it go to the highest point before it starts to descend again you have its top position, and just go as you mentioned 1, 2, 3.......

Thanks westpak ! Iv got a lot going and this was just in the back of my mind, preparing for Monday. I will just use my dial indicator with the spark plug adapter.
I take for granted then, that if you turn the crank pulley CW, since Fire order is 1-2-3-4-5-6 that as soon as #2 comes up TDC that it will be compression so long as #1 was compression and from there you just repeat 3-4-5-6

To do this right, it is really easier just to pull the valve covers. Not only does the piston need to be at TDC, but it needs to be on the compression stroke, with all the valves closed. It's easiest to do this with the valve covers off, although there are other ways as well.
As Gus suggestion, use a long screw driver inserted into the SP hole, to determine the moment it is TDC.
