Ray Cecil Posted October 21, 2019 Author Share Posted October 21, 2019 So, fired up little blue this morning....lifters are rattling like nuts. What the heck? Temps have cooled off, so maybe the oil is a little thick and not pumping up the lifters? I changed the oil Saturday night. I wonder if that has something to do with it? I drove the truck yesterday without any lifter noise. This morning it was obvious. Not an exhaust leak. For sure lifters. I used Rural King's oil and a motorcraft oil filter. I wonder if Rural King's oil is crap. It meets SAE SN GF-5. Harvest Kink is the brand. Never used it before, it was $9 for a 5 quart jug. I probably got what I paid for. Quick search online, no one seems to have issues with it. Maybe the 300 just doesn't like it. Link to comment Share on other sites More sharing options...

I use diesel oil, 15/40 summer and 5/40 winter, but we see a lot more cold weather up here. Link to comment Share on other sites More sharing options...

FuzzFace2 Posted October 21, 2019 Share Posted October 21, 2019 10w-30. If the filter has an anti-drain back valve it may not be working or They no longer install the anti-drain back valves in the filter to save money? Dave ---- Link to comment Share on other sites More sharing options...

I buy them at Rural King. I used 10w-30 Harvest King oil for the first time. I suspect this old engine doesnt like it. Going to get a better oil.

It may not be the filter but could be if QC was sleeping when that one came down the line Dave ---- Link to comment Share on other sites More sharing options...
