I need to just see if I boost the right amount of HP

Probably not a good idea. I've heard this can cause the front main seal to blow out.

There is a reason there is a breather for the crankcase. If you cap them off, the pressure will find somewhere to escape, and you'll find yourself spraying oil from somewhere.

That prospect doesn't sound like a lot of fun to me.

Im on like a search and destroy mission to find my boost leak and when doing so (pressurizing my engine) I took off my oil cap and and woooooooooooooosssshhhhhhh about 8 psi blew out of my crank case.......

Did you cap off the passenger side PCV hose? The PCV valve, if functioning properly should block the air on the driver's side.

Idont know what that is....All I did was cap the exhaust and intake and put the comppressor hose into the hose that goes into the point where the stock turbo pipes meet and turned it on.

There is a 1/2" hose running from the valve cover on the passenger side of the car to one of the intake pipes. (Pre-turbo) It is about 6 inches long. If you haven't blocked off this point you'd be forcing air into your crancase.
