I've been on this forum for 16 years now and still haven't done the CCV mod. I've done almost all the other typical PSD mods but for some reason I haven't done the cheapest and quickest mod out there. I started researching this one after finding the source of my valley oil leak coming from crankcase oil blowing out the end of the hose coming off the Y pipe going to the MAP. I would like to get this oil out of the intake but I started finding a number of posts about crankcase pressure increases causing oil seal leaks or smoke coming coming out of the hose when routed away from the engine. I assume if I put the CCV mod in with no cartridge at the end I won't increase crankcase pressure. Is there a vacuum component that I will lose by doing the mod that could increase crank case pressure? I don't want to put in a cartridge that will increase pressure but I also don't want to allow oil residue to drip onto the driveway. Do I route the end into an open container? Is there really a reduction in EGT with this mod too? Any other suggestions or comments?
