Zigg and Will .....Since both of you have "C59A" blocks, they are both "Canadian" blocks which have THREE threaded oil holes at the rear, rather than only TWO holes on USA blocks. You've gotta be careful how you plumb these things. Will.....I was very surprised to see you using the "return" orifice for your "supply" to the filter can. Maybe both of you can garner a little more info on these Canadian oil systems by reading the thread in the link below. There is a LOT of info available with pics and diagrams if you use the "SEARCH" function above in the BLACK band. Type something like "Canadian oil filter", or "Canadian oil system" for your search.
