Inliners International Forums General Discussion Engines 235/261 oil filters

It would be a full flow engine 1956

Also, a full flow 261 had a steel pin in the side of the block near the galley port. This steel pin needs to be hammered into the block about 1/4" causing the oil to flow out of the galley
port, through the oil filter and back into the pan port from the oil filter.
I do not know if the 235 had a steel pin or not?

Please clarify this as well. I will write it down for future refereance.

Thanks a lot,
BH
