Message: [QUOTE="6.0 Tech, post: 1557791, member: 23001"] So, think the saga has finally ended with this piece of shit… has had me banging my head as hard as I can on the wall every time I’ve had a chance to work on it. So after throwing a used set of heads in it from our race truck, thing still ran the same. Swapped engine harnesses, FICM harnesses, cam and crank sensors, ficms again, pcms again, tried everything. Tan a manual compression test and my bank 1 all 4 cylinders were royally ****ed. Like 50ish psi… pulled the motor again, no cross hatching on bank 1, had several valves that were leaking, motor went from ok to ****ed in about half hour of idling, no idea why. Built another motor with a good core we had sitting on the shelf. Used as many parts off the core as I could. Pistons, cam, crank, new bearings and rings, new set of heads. Dropped it in, ran the same. Got fed up walked a few doors up and talked to a big truck shop. He recommended swapping the hpop as cat engines will do similar when the pump is taking a shit. Never seen an 05 pump fail like that, but **** it. Put the pump in, fired up and revved no issue. I had left a lot of stuff off/loose/half assed assuming it wasn’t gonna work. So buttoned it all up, and no issues aside from an exhaust leak at the egr cooler to up pipe gasket. Fixed that, and then the ****er won’t start… At this point I’m contemplating eating a 12 gauge for lunch… so start going back thru and unbolt the down pipe, still won’t run. Said **** it and pulled the up pipes loose at the manifolds, and **** me if it don’t run… so pulled the turbo off and apart. No issues in it aside from sootier than a chimney. So while it’s getting cleaned I figured I’ll pull the up pipes off, cause at this point why the **** not, to verify there ain’t a bird or something stuck in them. Lo and behold the damn egr scoop on the short rh pipe had come dislodged and was blocking the entire pipe, and with a welded cooler the exhaust had no where to go. Come to the conclusion this is probably what started this whole fiasco. That thing come loose, back pressure on that side blew the valves open and bent them, then excessive back pressure caused the motor issue after head swap. ****ed up thing is with it being on the rh side ebp wasn’t showing any issues, but for all we know it could’ve been over 200 psi or something… Sorry for the long post, but figured this weird shit may help someone in the future… Sent from my iPhone using Tapatalk [/QUOTE]
