does anyone know the part number for the oil filter for a 235 chevy loadmaster engine the old one in my truck is a sears heavy duty filter .thanks in advance fred

I have a 235 in my '58. I bought a NAPA 1100 this past weekend, and it fit just fine. They have two filters for "heritage" engines- the 1100 is about 6" diameter. The smaller one (number unknown since it didn't apply to my engine) is about 3.5" diameter.
Bring your wallet. The filter was around 14 bucks.

Hope this helps.

Is that an external paper element? My 51, 235 is external. I use a Fram C4p. I get at Checker Auto(Mn). It runs $6.99 it think

Glenn,

the old timers i talked to said they just dropped a role of tp in the cannisters. i have never tried that. $14 seems fine.

I'd hate to fish out an oil-soaked wad of TP out of the cannister! But you are right- it probably would fit just fine.

I re-checked my receipt yesterday and saw the filter was $10+change.

Fred, my setup is an external metal "can" about 7 or 8" diameter, with two rubber hoses (~3/8" diameter) running to/from the engine. The can has a 7/8" bolt on top to hold on the cover. Under the cover is a little spring that the bolt threads through, and a gasket for where the lid attaches to the can. Inside is a riser tube (~1/2" diameter) that the filter assembly slides over. It reminds me of an old coffee percolator.

The filter assembly that was sold to me by NAPA looks like a coffee can, about 5" tall, with perforations all over the surface. Inside of this is what appears to be a paper element. There is a 1/2" hole top and bottom for that riser tube to feed through, and the top has a little bale that gives you something to grab to pull it off of the riser tube when it is time to change it out.

I haven't yet received my shop manuals ("they are in the mail") so I don't know if this is the stock set-up for '58. Judging by how period the rest of the engine appears, I think it either is stock, or was a typical after-market set-up from the early '60s, but that is just a guess. There are far wiser, more experienced, and older folks here that can give better information about this than me.

I,m 66 yrs young and keep hearing about TP for oil filtering I have been a GM mechanic for 30+ years of life and I think the idea of TP in the filter is the realm of wanting to trash the engine in the worst way,,beside that what would use extra soft,,large jumbo,,treated,sented,,,hahaha doc

I've seen thoes filters that use the TP.If the proper canister is used on the old oil it will clean the oil to it's new out of can color.As far as causing engine damage can't see why it would.Just soake in oil before it's installed.All filters should be filled with oil prior to installing so as to allow oil to flow as soon as possible.Insure that your mechanic does this when and always before the filter is installed.

If these TP filterscaused engine damage it's proably because the center cardboard roll was not removed,as specified by the manufactor.

The factory & dealer installed filters were A.C. They have a flanged bolt on top which uses a 5/8 wrench. It takes a 85100 cartridge (Carquest number). The aftermarket filters where Fram. It uses a 7/8 wrench. The part number for it is 85006. Napa part numbers are almost the same except the first 2 numbers may be different. I don,t think I would use TP for an oil filter. If it plugged up the return line would be one thing but if it got into the pan & clogged up the oil screen it would cause serious engine damage.

Fred,

Did you check out any of the filter numbers posted above? If one fit your Sears filter, please post that here. It might help someone in the future.

The NAPA 1100 oil filter recently cost me $9.38 plus tax. This filter fits the AC 1955-1962 canister. There was at least one other sized AC oil canisterr and it used a different filter.

Here is an old discussion on this topic.

The "toilet paper" filter was and still IS a bypass filter marketed by a company now known as WeFilterIt Inc. Its name is the Frantz Filter and has been available since 1962.

It does NOT replace a vehicle's standard filtration system, but is sold as an "oil cleaning" system that is installed at the motor's oil pressure sender location. You can read all about it on their web site:

Back in the 70s my next-door neighbor tried to get me to join his multi-level marketing pyramid, selling these things. Not too long afterward, he was arrested for polygamy, although I doubt those things had much to do with one another. However, I always regarded him AND the Frantz filter as crackpots.

Dont let this guy hear about the Toilet paper thing. The Man

The Frantz TP filter is not a crackpot idea. They really work, but the whole thing is designed differently than the AC or Fram filters. The oil passes thru a tiny hole, maybe only 1/16? Up through a tube in the center of the filter and then comes down through the length of the TP roll. There are screens top and bottom to keep the paper in place. Then it flows back into the motor. It is strictly a by-pass system. I wouldn't suggest anyone putting a roll of TP in there canister filter.

I used toilet paper as an oil filter in my old 57 3100 for five years. It was a daily driver. The tp worked great but is a little messy when changing. You have to use the old oil filter cannister and make sure that your remove the cardboard roller.

With these old partial flow filters, how do you know if they work or not? I run them on my 235 & 261, but I change my oil often. I don't trust those filters to do much at all.

I would say that this type of filter will work, but not very good. They only filter a small percentage of the oil. Better than nothing, but not really worth their weight and not something I would add unless restoring. A toilet paper filter I would never consider.

There's a really great article in the July/Aug. issue of Vintage Truck magazine by Bob Adler. In his 'Notes from the Corrosion Lab' he discusses the pros & cons of by-pass and full-flow filters. It might make you question the necessity
of having a by-pass filter.

Let me clarify my previous post. I changed my oil regularly. I was 21 years old, newly married, no money and without a pot to pee in.

If you have the money, buy the filter, skip the TP.
