After returning from a very pleasant stay in Southern California Feb.24 to March 13 (just before the Governor declared "Shelter in Place" (or whatever)), my wife and I had to go into 2 weeks of self-isolation. That wasn't necessarily a bad thing because I always have lots of projects that need doing. One of these was to finally install the spin-on oil filter adapter that I had purchased like 2 years ago from Hot Heads (sometimes called "Hot Hemi Heads"). I will use HH as the abbreviation.

The installation was not difficult but there were some minor issues that needed resolving along the way so I thought that I should write the process up in case someone would like some hints in the future.

The first "issue" was the logistic of knowing that in order to do this, the oil is likely need draining and once drained, if there was an issue along the way, i.e. can't get the old filter stuff off or the new filter stuff on, the car might have to be towed/flat-bedded to a shop. That was not the case but it was likely the reason that I never started this project before. So once I finally decided to do it, it was game on, hell or high water.

This might be easier done if you had a hoist or some kind of lift. I don't either (yet) so I had to remove the right front wheel and get the right side high enough to get jack-stands under the right side of the frame. That allowed some pretty awkward access to the OE filter components while sitting on the floor (on foam pad) with the area illuminated with an large LED trouble light and peering through a gap in the fender line rain shield into the engine bay (felt a bit like laproscopic surgery).

The first thing was to drain the oil from the oil pan (I was going to change the oil anyway). I had warmed the engine up a bit so the oil flowed better but not enough so I was going to get burned or anything.

The second thing was remove the filter canister and housing. The nut on the end of the housing is 5/8". I honestly don't remember if I loosened the canister from above before I jacked the car up or after but I did something and spun the filter housing off. This necessitated trying to catch the oil that was in the housing. I got most of it but some did get on the exhaust down pipe (and eventually wiped off with solvent before starting the engine after the oil change). This stuff:



With the canister off, the next thing was to remove the filter base. Well actually, I didn't figure that one out right away. I first tried to remove the canister from the engine bay and found that I could neither go up with it or down with it. That prompted me to post a question to the forum about why I couldn't get the canister out. I figured it out before I got the answer - I needed to remove the OE filter base first. Once that was out (four 9/16" head bolts), the canister could be removed easily.

This thread: http://www.forwardlook.net/forums/forums/thread-view.asp?tid=73507&...

Not all of the OE filter base gasket came off the block so I had to spend some time scraping that off so the HH adapter gasket would fit cleanly to the block. No biggy. Just a bit time consuming.

With the OE filter base gone and the old gasket remnants removed, I trial fitted the HH adapter with 3 of the four Allen head bolts that HH supplied. At that point I discovered that one of the bell housing/adapter bolts interfered with the HH adapter. I was going to remove the bolt and grind off the end of it outside the car but I could not get enough purchase on the bolt while sitting on the floor to get it loose. So I removed the HH adapter and ground the bolt end and the HH adapter with my Dremel and a grinding disc until there was enough clearance to make me confident that there wasn't going to be an issue with the full installation.

I then installed the HH adapter with the gasket and four Allen head bolts that HH supplied. Getting the bolts tight was tricky because of the angles and poor access resulting from the lack of hoist. I think at one point I was lying on the floor trying to get the bolts tight enough. I also used a 12" socket extension and a swivel at one point. Eventually I won.

After "rinsing" the "old" oil (<2000 miles on it) out with some solvent and new clean but not wanted oil (5W30 that someone gave me), I reinstalled the drain plug and spun the 4" tall WIX 51085 filter onto the new HH base. I filled the crankcase with Lucas oil High Zinc "Classic and Hot Rod" oil (I think it took a full jug after the engine was started and the new filter filled under pressure).

Next oil change, I will install a 5" tall WIX 51515 filter and a new oil drain plug gasket (this one is leaking a bit despite being very tight).

Hope this helps somebody at least a bit.

Yep the filter change on a hemi equiped vehicle is painful. I put remote adapters on the imperials I worked on and ran the lines to a spot easy to access with the filter
vertical to reduce spilled oil when spinning off.

One thing to note the way these cars were made. There is a ball valve inside the engine block that routes only a percentage of oil to the filter. There is a modern solution
to have 100% filtration with a little plunger type device. This is a job best left when you have the engine out and feel its a needed mod because it requires hammering
out the ball valve with the pan, pump, and rear main out of the way. Engines survived this long with partial filtration so its not a super important change.

Some, but probably not much, oil gets around the anti-drain back ball and they have done that since leaving the factory.

Thanks. I was fully aware of the ball check valve and how it only permitted partial flow to the oil filter, based on answers to some of my previous filter-related questions. *HOWEVER*, I am also fully aware that to get to the check valve, you have to remove the rear main cap. *AND* to remove the rear main cap you have to drop the oil pan (obviously). *BUT* to drop the oil pan in a 1956 Dodge V8, you can not do that with the engine mounted in the chassis.

So no go for me. Partial flow will have to suffice until such time that I have rebuild the engine and/or replace the rear main seal.

I did contact Bob Walker at Hot (Hemi) Heads and asked about the check ball and he said "Dave: There were two systems. The earliest had the cage and ball (backflow valve) but were already full flow. At some time Chrysler went to a combination of the backflow valve and a bypass valve. You can run the oil filter mount on either system. You'll just have a backflow in the block and the filter. Have fun, Bob"

Some diagrams regarding the ball check valve:

I put one of these HH adapters on my 1955 259 Plymouth. My car has an early dodge engine. The car was originally purchased in February 1955.

My car only had the check valve (non return valve) and it did not have the pressure relieving spring set up to bypass the filter in case it plugged up. There was a solid block (or the hole was never drilled all the way through). So I don't have any issue with bypassing the filter with the HH adapter. Some of the earlier hemi blocks didn't even have the non return valve I have heard. I don't know if this is right but I am certain my car did not have a filter over pressure bypass set up.

The original filter was really a bad design. My original filter block that bolted to the engine block, had a slot cut in the block from the filter inlet to the filter outlet. This slot constantly bypassed some of the oil around the filter. The slot was about 1/8 inch wide and 1/8 inch deep. I think in the early days, they put this slot in instead of putting the spring loaded bypass valve in order to somewhat protect against over pressuring the filter in the event the filter plugged off.

I don't think you will have any filter bypass the way you have it installed. The spring loaded bypass that is left in your car will be closed unless there is high differential pressure on the filter and it may be that the filter bypass on the spin on filter will open before this original spring loaded filter. Furthermore, it is better to leave this spring loaded bypass installed than it is to pull it and not put the correct plug in that prevents oil from bypassing the filter. Putting that plug in would be a little bit challenging I think.

You also have two anti drain valves installed now which is good. Less of a chance to drain the filter and have a dry start.

I installed the HH adapter when the engine was on the engine stand and I could really check out the oil passages real good so I'm sure how my car is set up. The HH adapter for me is massively better than the original filter. I use a PH8A filter because it is big and I think it may have more filter surface area.

All this is just to say that I think your installation is very good and there is no need to remove the original stuff and install a plug. You are at least 99% good in my opinion.

I also wanted to say that I don't think that ball in the ball check restricts any oil flow when the unit is installed correctly. There is some room in the cage that allows the ball to go higher than the hole going to the filter. So when oil is flowing, the ball is lifted up and out of the way.

I have studied this a lot because the guy that built my engine put this cage in upside down and lost the ball. The gage being in upside down covers about 75% of the hole going to the filter so I had low oil flow and wiped my main bearings. I don't know much about other cars but I really studied this a lot on my car. When the cage and ball is installed right, which I'm sure yours is, there is almost zero flow restriction related to the ball being in there so I don't think you have any thing at all to worry about on oil flow. I think you are 100% good. The spin on filter is a massive upgrade.

Hello 56D500.... If you need drain plug gaskets, let me know. I ordered one a few years back and got a whole box delivered. I have about 50 and can never use all of them.

Sam: When you get your new old stock 259 dual point set in the mail, use my return address and (please) pop a few drain plug gaskets in an envelope and mail them to me.

Thanks

Sorry to hear about your engine rebuilder and he/she screwing up on the ball check valve.

And thanks for the thoughts on the ball check valve and flow restriction, etc. I'm not worried. Next filter will either be a WIX 51515 or the Mopar-branded equivalent.

Seems small at only about 4" tall, similar to the WIX 51085 that I am running.

Yes, the NAPA 1085 (51085 Wix) is the direct cross reference.

I'm using the Fram PH8A, not the cheap version but the full synthetic version that filters out 99.9 percent of particulates. It's a lot heaver and had a better non return valve than the cheap Fram's. I'm not a real big fan of Fram but this high end filter is pretty good. I researched it a lot and watched the videos where the guys cut the filters up. I think it is a pretty good filter. It is a heck of a lot better than the original one I had.

Anyone want a C134PL cartridge for the original filter. I have one I will definitely never use. It's free.

I think in 1955 the industry was trying to decide if they were really going to use oil filters or not.

I did not realize that Fram made different grades of filter but apparently they all do.

The PH8A crosses to the 5" tall WIX 51515 series
