Where should piston be when pressurizing Engine?
Bottom.
Your intake and exhaust ports must be exposed.
That's why you need a block off plate for exhaust and a plug for the intake.
I use the block off plate on the exhaust to hook up a gauge and to add air.
CAUTION: if you use more than 10 psi you WILL blow your seals out. Most use 7 psi. I use ten MAX.
