The Stovebolt Site Forums The Shop Area Engine Shop 235 oil filters

Hey guys, Is there a way to mount the 235 oil filter can on the firewall? I'm running the clifford 4bbl and fentons, so no stock location for me. Is there a kit or something out there to mount the filter where the voltage regulator used to be on the firewall?

This oil pump mishap has me re-thinking the bypass oil filter.

thanks

You can mount it anywhere you want as long as it sits straight up and down and it's set out from the firewall to remove the lid. All that will take is a spacer, which you can make with a hacksaw, file and drill. Once you mount it, then you can measure and get some new hoses, either at a parts store or at a hose shop.

But, how about converting to a full flow filter? I can't recall how deep you are into the engine.

I don't think the 235 filter flows enough for a full flow conversion, though. The 261 oil filter takes bigger filters and has much bigger lines.

I welded a bracket and mounted mine off the frame. It has to be pretty solid though. The filters are pretty heavy when they are full of oil. I had thought about converting to new style but also heard that they are too restrictive for stock 235 oiling.

As stated above, the 235 full-pressure engine ('54-'62) has to be converted to a full-flow oil system before you can convert to a spin-on filter.

Check out the Tech Tips, Full Flow Conversion article on the Inliners site:

The 1958-1962 261 (Chevy truck) engine was a full-pressure, full-flow engine. It is ready for conversion from the (tall) canister oil filter to a spin-on oil filter. In would be interesting to hear from someone who has done this conversion.

A spin-on filter conversion kit can be purchased for about $25 (complete with fittings, lines, and filter head but no filter). This is easy to mount on the firewall (this is what I have done with my 1960 261) or low on the block (within the last month there was a posting in this forum with pictures - on a 261, as I recall).

SO WHAT I AM HEARING IS THAT ON MY 235 WHERE MY TO AND FROM LINES ON MY CANISTER FILTER ARE, I CANT JUST RUN THOSE LINES TO A REMOTE FILTER DUE TO NO ENOUGH PREASURE?

I've seen 235s converted to a full-flow filter with no apparent ill effect. Requires bushing down the filter head fittings to the small lines used with the bypass filter. Owners claim no loss of oil pressure, but any advantage would appear to be convenience, because the filtered oil still goes right back into the pan to mix with the dirty stuff. A true full flow conversion returns filtered oil to the the main oil galley, upstream of the bearings and rockers.

That's not what we're saying. Your current filter is probably set up as a bypass filter, only about 10% of the oil that is pumped goes through the filter, then is dumped back into the oil pan. There is another option when you have the engine apart for rebuild, which is to convert the engine to a full flow filter, where all of the oil pumped passes through the filter before going to the oil galleys to lube the engine. The full flow filter is better than the bypass, but the bypass is better than no filter. There is an article on the conversion int the tech tips section.

Codeman , you can indeed mount the filter to the firewall , that is how the dealer mounted it in my '49 . you'll need slightly longer lines .
