I just read a thread from another website,from a guy that is thinking about adding an aftermarket oil-filter to his 235. I had that same idea,when I first purchased my '55 2nd Series 6500. The answer that I received from my mechanic was:"DEFINITELY NOT!!" Our trucks were designed to operate efficiently with regular oil- change intervals. Adding an aftermarket filter only filters about 10%,anyway, plus you have to drill holes in a perfectly good block to do so. If you don't remove all of the shavings, it would cause pre-mature engine wear/failure,which would be the reason for adding a filter in the first place! PLEASE...Don't fix what ain't broke! | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | You are referring to two types of filters. The optional/accessory by-pass canister oil filter will filter about 10% of the flow, the other 90% does not get filtered. Over time, all the oil gets filtered. This works quite well. http://www.stovebolt.com/techtips/engines/oil%20filters/index.htmlThe block can be modified for a full-flow filter - that is the one that might cause wear if the shavings are not cleaned out. People who have done this seem to be able to clean out the shavings. http://www.stovebolt.com/techtips/full_pressure.htmThe by-pass filter is my choice. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | There's no need to drill any holes to add a filter to the 216/235/261. The factory optional filter connects using existing ports in the block, T-ing off the guage fitting at the rear, and returning at a port near the center of the block. Any filtration will extend the life of your engine.

It mounts where the oil distributor plate is located. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 |
The InnerLine filter only works on low-pressure 216/235 engines. One advantage of this type of filter is that it needs no hoses.
The 55-2nd series engine referred-to in the first post has no oil distributor. Nonetheless, a by-pass canister filter will work with any year 216/235 and 54-57 261 engines.

Also nothing wrong with the original type bypass filter.
If I were building an engine I'd for sure convert to full flow oil filter while I was at it.
