[QUOTE="DEEZUZ, post: 370076, member: 1508"] Yeap, its common... One truck JUST turned 102k and it came in for a contribution, the SFT was -18 so I knew I had a compression issue. Cold Compression test was awesome @ 430PSI, but thats only like 200 rpm. Idling it had a plain old miss. EVERY rocker, bridge, an dpushrod had damage. When I went to put the new pushrods in, I found a lifter that the circlip had come off and the top piece was loose, well, heads gotta come off at that point... This truck was run with synthetic every 5k. Ford is saying its because of fuel in the oil, wipes the already insufficient mist of oil off the rockers and causes this... If your not deleted, expect to do this 2-3 times in your motors life. [ATTACH=full]89574[/ATTACH] and here's #2 with the worn fulcrum [ATTACH=full]89575[/ATTACH] I dont like these 6.4s at all and I dont wish one upon my worst enemy. [/QUOTE]
