Crankcase Ventilation Perdicament

Post by 240nspec on Thu Apr 09, 2009 9:37 pm

Came home today to discover that the connector on the valve cover for the crankcase ventilation has some how come loose, thus small oil overflow plus loss of vacuum (and air intake). CEL came on and went poking around and Im guessing this might be the problem. The thing is the whole connector can be dislodged from the Valve Cover with ease, exactly what held it in there in the first place weld? One solid piece? non-the-less, temporarily blocking off the intake side of the hose will of course fix any vac leaks in the intake system, but what about the CCV? I can't efficiently block it off, as well I know it shouldn't be. Any idea's?

oh btw, 1 to 2 bolts on that damn thing (Valve Cover) is stripped, rather than taking it off running the risk of putting the 240 out of commission (My daily) any fixes not opening up the valve cover?

appreciate any and all of the help.

the thing is I posed a similar question way back when about adding a breather onto a N/A 240 and I rmeeber the overwhelming response was to not do it. I wish I could recall why but I had the same idea of just blocking it off for the sake I had a breather laying around in the garage. Not sure why again...

Your technically not supposed to run a breather on that but since its your daily you wont notice any affects by doin that. Unless your tracking your car and beating on it you should be fine

and Flick on that pic you posted i believe the only reason thats got a breather on it is because that piece isnt a PCV and if it was hooked up to the charge pipe you would pressurize the valve cover. I completely eliminated my PCV system when i went Ka-t
