Thanks for any positive help and sorry if this seems long but I have read way too much with out much clear info.

I am installing a V3 Vortech Tuner kit this weekend with Deatchwerk 600s and a walbro 225- Up Rev tune-one step colder plugs-new maf and have installed the transgo kit (way fun) already I have a 312 pulley and am concerned of belt slip and thought of sandblasting the pulley to pick up more grip?

Alright so far? Next problem I for see is crankcase venting I have read over 250 posts on z350 and with my knowledge of motors (40+ Years) I think many are lost on
CC venting so help me out Please as I do not want to replace my valve cover gaskets with the increase pressure from boost.

1st many want you too drill the PCV valve IMO wrong due to its metering of vacuum and for positive venting of unwanted vapors as well as keeping a better ring seal especially at low rpms. it also is there to prevent any backfire reaching your crankcase (a sure Seal blower)as well as effecting manifold vacuum that your power brake booster works from.

2nd when under boost you will pick up a positive pressure in the crankcase that needs venting and from what I can gather the PCV valve will push even more pressure into the crankcase and bleed off some boost as it is not a positive check-valve.

I hope you follow so far.

So here is where I need help as many have dealt with these problems see if this makes sense.As this is what I plan on to hope address these issues.

Install a brake boost check-valve between PCV and manifold vacuum to stop boosted charge returning to crankcase and install a tee in the hose between the valve covers with another Check valve only letting positive pressure out of crankcase when in boost mode and when off will close and let the manifold vacuum do it cleaning.

This seems much simpler and cost effective as well as addressing both problems when Boosted.

Running a catch can with a stainless scrub inside could be a plus as well as for the blow off line.

Well do you see any problems or missing something.

Thanks again for any positive help.
