Turbo testing...

[JMBT]

Thank you Rawze. So I have completely removed the crankcase breather system to check it and make sure it is open. I blew compressed air through the drain at the bottom of the breather case an all the breather hoses to make sure they are open. I am running the maintenance free insert and it has also been drilled at the top and I blew compressed air through it after I reassembled it to make sure the spring mechanism was working properly, and it is.

I know a bad air compressor can add pressure to the coolant system. Is there any chance it could add pressure to the crankcase as well?

Thanks
