Rotorhead Posted March 14, 2022 Report Share Posted March 14, 2022 Hello All, My crankcase filter keeps getting saturated with oil. When I took the cover off this time a little water came out with some sludge. The oil on the dip stick looks normal. I checked the drain line, it’s clear. As is the line coming from the top of the case. Why would it continue to get saturated with oil? There is a spring loaded disc on the left or front side. I checked that and it seems to be working, aka not stuck. Thanks. Quote Link to comment Share on other sites More sharing options...
spindrift Posted March 14, 2022 Report Share Posted March 14, 2022 How many miles on the engine? How much idle time has the engine seen? Both of these factors would contribute to blowby; hence the oily filter.

rickeieio Posted March 14, 2022 Report Share Posted March 14, 2022 Another contributor is not getting the engine hot. Short trips, light loads, bad on engines, diesels in particular. Are you driving the truck to work? Letting it idle to warm up before heading out? Bad, bad, bad.

I don't generally let it idle longer that required to build the air pressure. I was going to order one of the maintenance free cummins crankcase filters, which basically has the big filter removed and see how that goes, but it's about 150$.

Are those in the ECM as well? That's rebuild time if it was being used in a commercial application so I'd say don't worry about it since it's unlikely you'd spend the $30-40K for an engine rebuild. Yes, the ECM records idle time. Quote 2012 F350 KR CC DRW w/ some stuff 2019 Arctic Fox 32-5MCindy and Tom, Kasey and Maggie (our Newfie and Berner) Oh...I forgot the five kids.

GlennWest Posted March 15, 2022 Report Share Posted March 15, 2022 I made my own filter. Mine just has down draft tube. Detroit. I tied a gallon galvanized bucket under mine and stuffed it with steel wool. No more black spots on ground.

Rotorhead Posted March 15, 2022 Author Report Share Posted March 15, 2022 I remove the original drain for the crankcase filter because the plastic was brittle and broke. I put a rubber hose on as a replacement. Hope that is ok. Quote Link to comment Share on other sites More sharing options...

Just not worth it unless there's something very, very special about the truck. 4 minutes ago, Rotorhead said: I remove the original drain for the crankcase filter because the plastic was brittle and broke.
