Wear metals are up again, so maybe there is something going on with the lifters. Very similar report to the last one with T6 5/40. I went with Motorcraft Super Duty 10/30 this interval because our local supplier messed up the pricing, and I got a 12 pack for 11.68! Seemed to hold up decent, but the metal is worrying me. Im wondering if the sooty oil is from the upgraded injectors, and this is causing the wear issues? The cam looked fine when I was in there over the summer, and lifters had no serious scoring, and which is probably where the silicone came from. The cam wear issue theyre mentioning is most likely the later Pumpe-Duse motors. I do get a longer lifter tap on cold mornings, probably 5 seconds on one cylinder, which could be adding to it as well. I refilled with T5 10/30 that was on sale with rebate from Amazon, Hengst filter.
P.S I dont know what Im doing wrong with the file upload.
