If you don't time the stroke correctly you could end up shoving all that oil into the exhaust or the intake...I have the fortune of having it happen
So basically you'll want to find TDC on #1 then go backwards about 1/8 stroke before filling...but totally at your own risk! I'd personally find another way.
PS My crx almost lifted itself off the jackstands and blocks using the starter motor/breaker bar method!
