By-pass filter Installed - Rudolf_Diesel - 08-21-2009
I am engineering my own oil by-pass filter system. I am going to feed the filter by adpating a distribution block to the OEM oil pressure port. The block will have a port for the OEM oil pressure sending unit, a port for a pressure switch ( Electric fuel pump circuit ) and a port to feed the by-pass filter.
I am looking for a spot to dump the oil, I can drill and tap the upper pan, but I just changed the gasket on the lower pan a month ago.
I found a plug on the front of the engine above the vacuum pump and to the left of the power steering pump. What is it for? can I use it to dump the oil.
How many of you have a by-pass filter and how did you do it?

The injection pump has a fill port on the side (below the ALDA nose) that would be a very easy dump location.

So it would not hurt any thing to use this port...I would essentially be dumping onto the timing chain.

I thought about tapping the filter housing, but I like to keep everything in a state that one day it can be put back to original. Even with the mods I did to the turbo, everything can be back to OEM in a matter of hours. Obviosly the turbo drain cannot, but that is how they should have done it - silly Germans
I don't want to drill and tap my valve cover. I have a lot of hours smoothing and sanding as well as my pretty paint job

That may be a good spot to use, I could maintain a steady supply of oil feed to the pump. I know it is getting oil, but I want to ensure it is steady like the MW. I was going to make a billet bottom cover with fins and a port to supply oil, but this idea may work better.
How do you like the system?
Can you notice a difference in the look of the oil?
I was looking at the FS2500 system, but I imagine it is quite pricey. It looks great, but alas I am a skpetic and must see for myself and I also like to do my own fab work. I am going to use a 3 micron filter that is available at McMaster-Carr. The filter housing and filter is about $ 35.00 and replacement filters are about $15.oo.

Quote:How do you like the system?So-So. There is no visible difference in the oil but it does reduce soot content according to my oil tests. I added a neodymium magnet from a hard drive to the filter bottom for extra metal-catching ability. I also put one on the oil pan drain plug since I can't find a replacement plug with one in it.

After getting a cut in hours (temporay I hope), I decided to keep the project on the cheap. I remembered seeing a filter housing in the garage and dug it out. It turned out to be a Frantz Filter circa 1965 ( a TP filter for those that don't know). My dad bought it when he had his first Corvair and paid about $40.00 back in the day.
I needed a little cleaning and polish, but otherwise was complete. I had to extend the inner pipe - someone cut at one time.
Here are some pics of the install:

I ended up changing the dump location for the by-pass filter. The pump was filling up to fast and it ended up damaging the fuel cutoff vacuum actuator.
I decided to go with my original plan and use the plug on the front of the motor.
I drilled out the plug and tapped it for M12 x 1.5 threads. I did not machine the face as it looked as though it made contact with idler shaft - maybe for some additonal support?
I also added a couple of reliefs to make sure the oil had some place to go just in case the shaft did not allow it to flow freely, so far so good.

Nice work, looks good.
It would be interesting to get the results of an oil analysis as well.

Is there a reason you didn't use a sandwich adapter for pickup and drain?
RE: By-pass filter Installed - Rudolf_Diesel - 03-01-2011
Not available for this style of filter we have.
RE: By-pass filter Installed - dust - 03-01-2011
I just looked up the oil filters for the Merc, and noticed they were canister. Don't know why I keep thinking mercs are spin-ons
