vacuum pump to decrease blow by massive, crankcase.

[PFL]

Hi guys

I see some guys talking about ventilated catch can to decrease crankcase in high boost, but sometimes it is not enough. the crank's rear seal ends up being blown. What are you doing to avoid blowing your ass? I'm using 12an in valve cover with catch can open. which vacuum boost are you using?

thanks for the reply, i noticed on ls1tech the guys are using Gz, it is by belt engine, do you have a photo of your compilation? I was thinking about an electric pump, but I didn't find options.
