Re: [Amc-list] 195.6 full flow oil filter/pump

[Frank Swygert <farna@xxxxxxx>]

There were other seemingly odd and pointless (considering the engine was being phased out) modifications made in the last year or two. The cam bearing size changed in 64 or 65 also. Building a 195.6 made after mid 63 model year can be a real headache getting the right cam and bearings now. I think the changes were related to testing 232 items, but no way to verify that. Might have been changes to reduce inventory, but I don't know if the late 195.6 cam bearings are the same as the 232 or not -- of course the cam itself is different (195.6 is about 3" shorter than a 232). Who knows? 

I'm not sure the lack of an oil filter is a long term reliability factor in the old engine design. The first L-head I owned had 170K+ on it and had never been torn apart. The first OHV I rebuilt had 130-140K on it and was still running decent. It had been run hot one or two times to many and the rings were loosing tension. The relatively slow turning engines seemed to be fine with a partial flow filter. Solid lifters helped -- no small passages to stop up. That's one reason the aluminum engine required a full flow filter. I've never seen a hydraulic lifter engine without a full flow, but then by the time hydro lifters became common so had the full flow filter. More filtering never hurt, as long as there's plenty oil flow after the filtering.

Hell yeah! It looks like the weak point for long-term reliability with this 
motor could be solved. It's odd they bothered to add it to the last year's 
motors. It probably "fell out" of the 232 design/deploy phase; the aluminum 
195.6 apparently shares valve train components with the 232 (you can probably 
drop 4.0 lifters in it!)
