    I currently have my 235 torn apart for a rebuild. It will be back in the car soon, and I am debating on whether to install the accessory bypass oil filter or not. I have read lots of stuff saying it's not neccessary, and I've seen a lot of cars without them. I also see guys who swear you have to have them. I plan on changing the oil every 2k miles, and frankly, I don't like the way it looks and some ebay cash for it would really help me out right now. Plus i have a 292 that will go in the car eventually.

    So, not just on the Chevys, but for any car that had an optional oil filter, do you guys think they are absolutely necessary or not?

    No filter is 'absolutely necessary'. All they do is keep your oil cleaner. So, it's up to you.

    Any filter is better than no filter. A bypass will get the oil cleaner than a full flow. It just takes longer for all the oil to go through the filter.

    The old "filter or not" debate pretty much raged on in the 50' and 1960's , but by 1970's the predominant consensus of Society of Automotive Engineers (SAE-I) was that any filter was better than none. This conclusion was based on actual testing of reciprocating engines and bearings.
    {Mahle Clevite Corp still does significant testing on filtration, oils, and wear} .

    And, oil screens are "filters", and thus this is why they are described by particle mesh sizes.

    Then again, if you beat a dead horse enough it will not need any oil filter. :D
