what routing for crankcase vent hoses w/webers?
 

I'm in the midst of replumbing/simplifying the hoses on my engine. have webers. can anyone tell me the simplest/easiest way to route crankcase ventilation hoses. have a port in the back of the fan housing which I plumbed to vent housing as pictured. where to go from here? run hose to oil tank opening next to filler? thru a filter to atmosphere? run hose thru 'y' to both carb rain hat holes? please help! emissions not a concern. thanks, Don.http://forums.pelicanparts.com/uploa...1172961718.jpg http://forums.pelicanparts.com/uploa...1172961748.jpg http://forums.pelicanparts.com/uploa...1172961790.jpg

Hi:

You REALLY REALLY don't want to connect that fitting on the fan shroud to the breather,...:) :) :)

That simply pressurizes the crankcase which will blow out out of every seal you have on there and make a huge mess. That curved tube is for MFI-equipped cars, only.

Connect the large spigot on the breather cover to your oil tank using a 901.107.394.00 (as factory) and cap that curved tube on the cover.

One last thing; those dial-type fuel pressure regulators are just junk. They are restrictive as well as do a poor job of regulation. Get a Holley Low-Pressue FPR (0-5psi).

That fuel reg is worse than junk, it's a fire waiting to happen. I use a dual diaphragm reg, although it's over kill for $90.

anyway, i fed the engine breather to the oil tank w/stock hose, attached a normally twisted washing machine drain hose to tank and a K&N breather. Many guys use a oil catch can instead of a straight breather. It works for me as i have a tight engine.


the pic is when new and filter still looks good. The final hose distance and rise is nice although some guys just put the K&N directly on the tank with predictable results.

thanks guys! I'm on the right track now. and I'll go in tomorrow and trade in the regulator for the holley, funny, I looked at that holley and then cheaped out. oh well, should really know better. thanks again, this forum has saved me a TON of grief. Don.
