[QUOTE="Maryland dieselnick, post: 1272517, member: 22661"] Sorry, what was the question? Will dieting get rid of it? If so, it would need to involve a new PCM strategy that stopped the blast furnacing of those driver's side valves causing the thermal expansion. **** I do not endorse or recommend: tampering, removing or altering emmision control devises or strategies in any manner or form ****** That aside, it has to be kept in mind that it will not change the fact that the clearance is physically too tight on a some trucks and others ok. There are varying tolerance here between those two thresholds. How tight ones really are is the huge variable. If they are like these in the example Nchighcountry posts that they are so tight that at room temp on the bench, that might be a case where even if he had taken steps that eliminated this exhaust stroke injector firing with its accompanying thermal expansion with the resulting stiction, it would still be vulnernerable to stiction over time with that normal stem film building up a bit over time thru periodically seeing less than the best fuel, coupled with the engine living at relatively low rpms thru all those gears the 6.7 has. This would be a case wear wear in rate was lower than stem film build up rate. It really depends on how tight they are, the thermal expansion event, quality of fuel, ect. [/QUOTE]
