How do you put a catch can on a vt

[tayna17turbo]

hi guys
just wanting to know how to put a catch can on my vt commodore?

I'd like to do the same to the VY, anyone got step by step instructions and opinions on which type are the best? I just cleaned my plenum and would love to put a stop to the oil getting back in there again!

Remove plenum lid, remove plenum, tap hole, insert pipe, fit can, refit plenum, refit lid. Route the plumbing external to plenum, then fit can, then back into plenum, if you want and easy clean option. Refit new valve whilst plenum off, etc etc. But it shouldn't be much of a problem if you have good compression on all cylinders... if you've got a blow-by problem that's what you need to fix.

Run the engine with the oil filler off... if there's air/gas/oil blowing out through the open hole, you've got bigger fish to fry than a bit of oil getting into the plenum.
