Default Boost leak test DIY question

I purchased everything for the Boost Leak DIY on A4mods.com and I also put in a regulator like the one in this DIY from audigeeks hell, I even went out and purchased a portable air tank. I have everything together and ready to go but I have one question.

For the step in the 1st link that says,
In order to perform the pressure test, it is very important that you disconnect the PCV return hose from the TIP. This WAS NOT written in the writeup I was following.....
what happens is that after the system is pressurized, oil comes back down the pcv pipe into the TIP...and hence the turbo....you will end up with blue smoke in your exhaust.....in order to stop this you have to disconnect the check valve for the PCV return line and plug the hole
I used a rubber wine bottle cork and a hose clamp to plug the hole
well I'm not exactly a wine kinda guy - what did everyone else use to plug this line in the turbo inlet pipe?

In my AG write-up, I used an ABS dishwasher drain. You can use anything that hasthe appropriatediameter to plug the holereally. The only reason you need this is to plug the TIP so air doesn't leak out.
