Message: [QUOTE="Zeb, post: 1527984, member: 30304"] We bought our Excursion with 119,000 miles on it. At 115,000 miles they had rebuilt the front end, replaced the egr cooler, and a bunch if other stuff. At 175,000 miles I had it tuned. At 195,000 miles the ICP sensor started leaking, so while I had the turbo off I switched to an 06 intake, and did an egr ******. At 225,000 miles I put a FICM in it, and at 232,000 miles solenoids on 2 injectors failed. Built a set of 175/30’s, gutted the banjo bolts, put a blue spring in it, and had Jesse Warren write me a conservative tune for it. At 259,000 the head gaskets had finally had enough. Pulled the motor, put in a Straub cam, bumped the injectors up to 205/30’s, did a Marty’s fuel system, Irate T-4, and a 362/68/.83. Some time shortly after this I put on an ODawg S3R manifold and CNC Fab Stage 2 hpop. Also put in a CSF 6028 intercooler, Hellwig sway bars, Platinum wheels, Nitto 420’s, and Fox shocks. At 272,000 miles I decided to swap in an RCD Stage 1 cam so pulled the motor again. Found several cracked rocker arms, exhaust valve marks on a number of pistons, and 0.090” end play on the crank. Put in a DPC Heavy Duty Triple Disc converter, new bearings, another crank, ARP rod bolts, RCD Stage 1 cam, a fresh set of heads, and swapped the 362 for SXE63/68/.83. One of the heads had the valve recession too shallow (0.003-0.005” under minimum factory spec) and I decided to run it. Big mistake. At 282,000 when we were 7 hours from home I broke 2 rocker arms. Pulled the motor again, put in fresh factory rods, new 6.4 rocker arms, new pushrods, new lifters, Colt Stage 2 cam, delipped the pistons, fresh heads, powder coated a bunch of stuff, reworked the fuel system, wrapped the exhaust manifolds, and stuffed it back in. Recently pulled the injectors and bumped them up to 225/30’s. At 296,000 miles now and it’s running great! Next big project is 05 style suspension and front end conversion. [/QUOTE]
