We autox’d it last fall the weekend after we missed the Challenge. Blowby was so bad through the airbox that we thought it blew a head gasket. This was essentially the first time we’d had it running/driving since I’d owned it. Probably the first time it’d run in years. I looked into buying a catch can but that costs money so I happened to find a stainless steel soap dispenser on the shelf in the bathroom. I lopped off the threads for the pump and opened it up to 1”. Found a Mr Gasket breather at the parts store for $5 and popped it in. Used an old Nebraska liscense plate as a bracket. I’ve since found a clamp to hold it on instead of the ziptie.
