AMCTech Posted August 7, 2005 Share Posted August 7, 2005 Folks, Not to long ago I inherited an 03 f450 with ambulance body from another dealer. The first engine had failed due to a defective injector, #8. At the time, the unit had about 25k miles. The previous dealership installed the "6006" Motorcraft engine, and that is reflected on OASIS, along with the diag and repair analysis narrative which stated "misfire condidtion, with WDS power-balance and relative compression indicating cyl# 8 down; confirmed with manual test." Curiously, no other service parts were on the report other than the engine. Well, 18k miles later and the unit rolls in to my bay with a misfire condition that I confirmed as #8 cyl compression down, with no apparent failure of sealing washer or physical injector itself. Sorry for being long-winded, but I've only ever installed the production 6007 engine and never had any feedback on the Motorcraft unit. Either way, it looks as if it will be an ESP job.

Keith Browning Posted August 7, 2005 Share Posted August 7, 2005 Boy, that story almost sounds suspicious. Two engines in one vehicle with the same major failure? Is it possible that there may be an underlying problem that is causing #8 to damage the cylinder? Anyway, be thankful it's not a van! /forums/images/%%GRAEMLIN_URL%%/smirk.gif Quote Link to comment Share on other sites More sharing options...
AMCTech Posted August 9, 2005 Author Share Posted August 9, 2005 I agree, as the symptoms would seem to point to a pattern. However, there has been 10k very hard miles since the prev engine rr, so who knows? The ambulance conversions seem to be more problematic, and I vouch that the many problems come from sloppy series connections with the heater hoses...air in the system, poor splice junctions, etc. That then becomes the weakest link. And yes, I hate the 6.0 van /forums/images/%%GRAEMLIN_URL%%/frown.gif . I have one now but it has a trans problem that wound up simply being a solenoid pack. I never thought I would hear myself type that..... Quote Link to comment Share on other sites More sharing options...
