bad idea or terrible idea?

[iceminion]

the hole i drilled was in the balance shaft chamber, it was very thin, only about 3mm thick. the drips are weatherstripping adheasive.

On my buddy's turbo ford, there is a hole drilled in the aux shaft chamber similiar to where i drilled it on the 4g63. The turbo ford motor guy never has had a valve cover leak, and wonders why 4g63's dont have a crank case vent, only the head pressure relief vents.

should be installing the engine tonight!
