IPD came out with some ISX pistons that they were testing at lower compression did some of those sneak in there? there are many different pistons designs for certain applications now. Is it the right piston and liner combo?

honestly you would be ok at 7-8 degrees BTDC under load and still not be quite where that spray pattern is, and you say your down in the 2-3's? Something aint right there.

It is in fact down in the 2's and 3's with no master offset.

What is the injector part# stamped on the side of the injector(s)?? -and where did they come from?

I would recommend that you bring that thing down here after it is back together so I can do some testing of the injection timing to see if its audible break-over points are at the right degrees offset(s) during idle. - That would tell me for sure if something was wacky or not. - I can only do that by sound unfortunately, as I know exactly what to listen for.


And your positive that the #4 wedge was in the injector cam, and the #6 was in the valve cam? -- AND that the crank pin position was absolutely correct? and it was not slipped into the wrong place when assembling that thing? - these things are critical, as any error mechanically results in a much larger (2x amplified) SOI error.


I know you were not expecting to see this, but did you happen to wedge it again before tear down to see if anything had slipped?

--- it just does not add up.

Also, still I think you should have taken me up on my offer to do it here. Maybe a second set of eyes would have found something more significant?.
