Relocating oil filter M104 320. How to?

[hismajestics]

I need to move the filter to make some more space on the intake side. Anybody with a clever idea what would the set-up look like and what is needed? Thanks.

Going to do the same thing shortly for my itb swap. The easiest way is to use the oil filter housing from the m103, then fit an adaptor plate on top of that with lines going to a remote filter.

To fully understand this...

The first pic is the M103 oil filter housing w/filter, right (?), but is the second pic a M104 featuring a relocated M103 oil filter housing (the blue one) or...is it featuring a set of nice ITB's?

Btw, really nice package, what is the motor set-up?

The first pic is the m103 filter housing and filter, you will only need the housing though. The second pic is the m103 filter housing bolted on to the m104 block, but still with the filter still in the same place. (the blue part is an adaptor plate for an oil cooler connection.)

Use the m103 housing but fit something like this: MOCAL REMOTE OIL FILTER KIT HONDA SUBARU MAZDA PORSCHE M20 3/4UNF M18 13/16 RFK6 | eBay instead of the oil filter. That way the oil filter can be mounted anywhere you like, giving plenty of room around the inlet manifold and it dosen't come any higher than the top of the block.

The m104 in the pic is a hagmann 3.4 running an itb setup, not sure of the power output as each engine is custom built.

I checked with Matt (the shop) and these will suit my engine as long as the housing has a M20 thread for the oil filter.

Do you mean that the M103 housing replaces the whole M104 assembly pictured here? Even the "thing" the arrow is pointing?

The arrow is pointing at the oil cooler, that is the later water to oil type in the picture. Earlier engines had a separate air to oil cooler mounted behind the front bumper instead, but they tend to get covered in dirt too easily.

Using the m103 oil filter housing gives you 2 options.

Option 1 is to use the water to oil cooler from the m103 engine, which can be joined to the existing coolant pipes.

Option 2 is to fit an "in line" air to oil cooler in front of the engine coolant radiator, and connect it to the remote oil filter pipes. You would need to block off the coolant pipes that used to go to the m104 oil cooler though (very easy to do).

Many thanks for this information

Now, knowing the above, I'm planning to use the radiator/oil cooler set-up from the W114. Thanks again, carat

No problem, let me know how you get on.

Was that a gearbox oil cooler or an engine oil cooler? If it was an engine oil cooler, half the job is done already.

I finally have my M103 oil filter housing. Some size differences...



and as said, fits perfect.

 

[hismajestics]

Some practical problems occurred. It seems very tricky to find proper adapters to fit this Mocal kit to my W114 original oil cooler.



Thread in the cooler is male M22 and Mocal fittings are 1/2 BSP. Also, a bolt on M22 female push lock fitting seems to be a scarce item

Does anybody have a solution for this?

Try a local company that repairs / makes hoses for JCBs and other hydraulic plant. They will normally make up any hose at any length at a reasonable price

Try these fitted between your cooler and the mocal fitting: Hydraulic Adaptor 1/2"BSP male - M22 female | S.11978 | Malpasonline.co.uk

Thanks, this is it!

Can I add that it's not the metric thread that's the problem converting Merc cooler ends it's the male ball end of the fitting that's not compatible. Here is a sulution I used.



^These are end fittings from a US model W123 which are then swaged into normal hydraulic pipes and mated to whatever you fancy from your adaptor using standard couplers. See post #14. The other option would be to have 'normal' fittings brazed onto short lengths of these pipes.



.

Be aware that the coupling ends of these coolers are ally welded to the tanks and are vunerable to overtighening ie, they can snap off if abused.

These are the (original?) hoses I pulled off the M114 oil filter housing.





Should I remove the original fittings from these hoses and use them rather than use a M22 female adaptor to 1/2 BSP male to plug in the Mocal fittings to be sealed with eg. Locktite ?

Shown here Mocal 1/2 BSP male-to-male, M22 original MB fitting to Argus 5/71 and Mocal 90 degree 1/2 BSP.

What fitting is on the other end of the merc pipes? Is it m22 as well or smaller?

It's smaller, unfortunately forgot to measure it while at the garage.
