PCV - intake stuff

[spook420]

so i ve been running my big 1.6 all around town now and been noticing a few things.

 

oil dripping form the air cleaner and down around the carb. on too the exhaust manifold. looks like its due too the the crankcase vent on the valve cover pushing air out instead of in?(the line thats connected to the air filter)

already ordered a new PCV valve. also look like the vapor vent line has been disconnected and capped. anybody have any thought on what direction i should go now?

 

 

weber DGAV 33b1 carb.

The PCV seems to be connected properly, even if home made. The PCV valve can only absorb a limited amount of vapors. It works on manifold vacuum and when the motor is floored the vacuum is low. When low, any extra blow-by past the rings is directed out the valve cover vent to the carb to be sucked in and burned. I would say your motor has plenty of blow-by, in fact too much.

 

The easy fix would be to connect the hose from the valve cover into a small container to collect the oil. I would lengthen the hose and run down the far side of the motor by the starter. There is going to be a lot of fumes and this will let most of them be drawn under the passenger side of the car so you won't smell them as much. Avoid heavy throttle and high revs. yeah, right... :lol:

no promises on heavy throttle or high revs...its an original motor and 3spd trans not sure if its been rebuild ever.

 

i was going to get a container like that, i saw them on eBay for cheap. good idea!

 

at some point soon im tearing it all down and put all new from the ground up. maybe once i find a L20B motor and a 5 spd.
