I found a reference to a filter that was meant to be plumbed into the oil overflow in the rocker arms of a Stovebolt Chevy in this book. Anyone ever seen one of these things before? It's just so odd I feel like I need to know more about it. Did the lid come off and there was a little cartridge filter inside or what? Anyone have any better pics of one or description of it's operation?
For anyone who stumbles upon this page in the future because they love all things related to the early Chevy inliners, I bought one of these NOS filters off of the auction site and here's what I found. The oil runs in thru the 90 degree br*** fitting just like the stock babbit pounder rocker ***embly does. The oil then dumps into the big cast br*** cup. There is a Purolator filter inside that looks like a big fuel filter with a large cardboard disc on one end. The filter has a coil spring in its inside diameter which seems to be meant to keep it from collapsing as it fills with particles and offers more flow resistance. In the event that the filter completely clogs, there is a byp*** spring on top of it that would allow oil pressure to push the entire filter up, causing the stiff cardboard disc to rise up off of its seat and put the filter into byp*** mode. The oil proceeds out of a small hole in the area with the byp*** spring into the rocker arm shafts where it dumps over and out thru the br*** tubing later. Pretty much what I expected. Does anyone know of any other weird accessories for early Chevy inliners?
How about that statement in the first article about using filters in general on stovebolts: "but by using the filter, oil never needs to be changed"
