Default question about tdc and leak down test

is there a better way to find tdc than using a long *** screw driver? my engine has the crank lock pin installed right now that mean 1,3,5 are at tdc right? if so rotating the crack over one time till the mark on the harmonic balancer meets the arrow again means 2,4,6 will be at tdc???

whats the firing order, is it :

FRONT
1 2
3 4
5 6

also what PSI should i use for the leak down test


thanks in advance

Default If your crank lock pin is in, it means that Cyl 1 is either at TDC or BDC.

Remember, it's a 4 stroke engine.

You'll then need to hand crank the engine in the firing order to get to each of the next TDC's per cylinder.

Default it can be 180 degrees off, you need to make sure the big holes on the cam sprockets

are facing inwards.
