How to set the piston TDC compression stroke for leakdown test?

[Spoolin4Ever]

I bought the leakdwon test from harbor freight. How do I know when it's at TDC, and on compression stroke?

You can also simply remove the upper timing belt cover and turn the crank until the dowels on the cam gears are both pointing up and the white mark on the gear teeth line up.

Wow the official unofficial DSM leakdown test! Totally rad! thanks I really appreciate that!

You can also simply remove the upper timing belt cover and turn the crank until the dowels on the cam gears are both pointing up and the white mark on the gear teeth line up.

That might work for the first cylinder, but I need to do it on each cylinder separately on the compression stroke per each cylinder So no that wouldn't be the solution! Thanks for chiming in though...I appreciate it anyhow.



It says:
"To do this, put a long phillips screwdriver or skinny 10" extender down
the spark plug hole and turn the crank until you find the point at which the skinny extender is neither rising nor going down. "

Is that also when the adapter (or a long scredriver, whichever you put in there), is up high?
