I had the same problem on occasion with my I4 1800 digifant in my 82 westy. I tried different filters, but always used the same 15 50 Mobil 1 synthetic oil. Problem always went away with filter and oil change no matter what filter. Problem seemed to coincide with time to change oil, ie every 4 months ( yeah, I changed it that frequently. Figured the engine was working hard in hone van).
