Alternative oil filter and oil cooler system - PeachParts Mercedes-Benz Forum

MercedesRover · #1 03-07-2007, 07:14 PM

Hi all,

As some of you remember, I installed a 616 in my Land Rover about 6 years ago and since then have been building and selling adapter plates to mate the 616/617 engines to the Rover transmission. The size of the Benz oil filter housing has always been a problem that has been remedied in a number of different ways, none perfect.

To make it easy on everyone I’ve started to make an aluminum block that bolts in place of the original oil filter housing with ½” pipe-thread ports so you can plumb in any type of remote oil filter, oilstat and oil cooler system you prefer. You could also add an oil-bypass filter in the system if you’d like. The block is made from 6061-T6 aluminum.

I made these blocks to address a problem with space when these engines are installed in a Land Rover, but thought some of you here may like the opportunity to install your own type of oil filtration/cooling system and replace the antiquated Benz filter and the housing that contains it. I know how interested some of you are in oil analysis and having the option of upgrading to a modern oil filtration system may sound like a good idea.

If anyone’s interested in one, drop me an email.

Very interesting. Where do you hook up the oil pressure gauge with the new set up. Do you have to install a thermostat with the oil cooler since the thermostat is in the oil filter housing?

I can drill and tap a port if you want to retain the original mechanical system or you can put it in-line away from the block.

Yes, an "oilstat" should be plumbed in-line to bypass the oil cooler until the oil temperature reaches proper temp.

This will fit 617s too correct? If so it opens up the possibility of mating a turbo 617 engine and a W115 body. This will make you a very popular guy!

Yup, bolts to both a 616 and a 617.

I noticed on your webpage that you originally modified an oil filter housing partly because you wanted the oil pressure relief valve. Do you now consider that unnecessary?

MercedesRover · #7 03-07-2007, 08:11 PM

No, I still think it's neccessary but most modern spin-on oil filters have a high-pressure relief valve built in.

Good question though. Thank you.

You could also make one that fits the engines in 114/115 chassis to get the filter up top like where it ought to be

... so the oil can drain out after shutdown and starve the engine for that much longer during the next startup?

I'd mount it vertically (w/ the opening 'up') so that the filter couldnt drainback (even tho the fram allegedy has an antidrainback valve)

Of equal importance is the ability to fill it up w/ oil and screw it on when changing the oil.

What concerns me is the hoses, I know they can handle the pressure, but can they handle the vibrations @ idle from ol shakey under the hood?? I'd want some sort of intermediate bracket or stabilizer on the hoses.

I will never buy FRAM anything if I can help it. If you use a real oil filter the check valve will work just fine and keep it filled with oil.

The stock oil cooler hoses have done a good job... they do have a finite lifetime like all hoses though.

do you think you could make a female version to fit on the end of the existing filter? so it could be remote mounted and retain all MB's stuff...

Sure. It would just mean tapping the threads from the opposite side of the block. Long bolts with nuts on the back side of the block would keep things together. Add a home-made bracket and Bob's yer uncle.
