Hi recently taken car to garage for gasket leak they are concerned about vapour from 2 breather hoses which has a v attachment into a bottle ..it fills quickly I have changed the carb to a weber 34ich which came with a pancake filter with no breather attachment ...if I changed to a different filter with a breather attachment (what filter to get?) would this help the prob also there is no pcv valve ...sorry to go on I am a novice completely at the mercy of the garage thanks

Hi Cassie,
I don't think I can help much, but I also have a 34ich on my Saab and have the original plastic (later type) airbox on the top. So the breathers plug into this.
I had to make up a small adaptor ring as the top of the Weber is smaller than the old FoMoCo carb. I can take photos tonight if it would help.
Steve.

If there is no PCV valve or closed crankcase ventilation system, the vapours have to come out somewhere else...
