I need help identifying the oil filter on my M38.
I've been through the on line manuals as well as Wes' photo pages, and
several vendors pages and can't find one with the ridged top like mine.
The orange would suggest a Fram, and I've seen one with the ridged area on the bottom, but not on the top, and certainly nothing with that weird stamped T-handle on top. Only two fittings, one on the side near the top, and one at center bottom.
This site shows a fram description of the F3 & F4. It mentions restrictors needed if oil pressure falls. This may be similar to the restriction orifice in your oil return line.
I have seen this type oil filter fitted on jeep engines when used in stationary applications.
With these element type filters, you need to always keep a filter in it--the oil being pushed through the filter creates the restriction needed to keep from bleeding off too much pressure and scoring a bearing. _________________ Harold W.
