Installing my engine in winter weather has caused me to have a couple of possible "mods" on my car. The hoses for the oil blow-by (from the filler) and the fuel vapor that return to the metered air elbow were very brittle and snapped on me. I'm out of parts money and would like to use what's left of the breather hose and attach a catch of some kind, route the vapor safely to the atmosphere and just plug the hole in the intake elbow. While I feel mildy guilty about possibly asphyxiating some critters on the road, I'm more concerned whether these would be considered "illegal mods" or that I'm missing something about the purpose of those hoses and the car will run crappy. What do you guys think ? Thanks
Yes, I know I'm being cheap, and could buy straight hoses to replace them, but I just want to be done wrenching on the damn thing :oops: thanks
I think you need to keep the crankcase under negative pressure to keep the oil in place under the cylinder walls.
Problem is the crankcase vapor is bad for performance so... if you installed a extra catch can or vapor seperator that would be illegal. stock or same as stock hoses need to be installed between the stock vapor separator and the intake.
do I have it right Joe ?
