6.7L didn't quite make it across the lake bottom

3000 miles on the odometer, and this college kid takes his new truck out to Sardis Lake and proceeds to embarrass himself by ingesting water into his engine...

 

Low compression on 2 and 8, loses oil pressure once EOT rises above 180 degrees, ominous noises from crankcase area... Interestingly, it loses fuel pressure off idle. FRP_A rises from 4500 to 14000 without a hitch, but then it drops off. FRP_CMD drops too, and I can't pin down what is causing the low FRP command...

 

Anyway, quoted $15K to repair. His dad was surprisingly cool about it. He asked me to push the vehicle back out into the lot and give him a few days to calm down before he makes a decision..

 

should be interesting..

Finally got approval to perform the work. Swapping the long block on this bitch sucks - there is a lot to transfer over.

 

However, if anyone finds themselves in this position, do not forget the crank sensor tone ring. It is a little disc that goes between the crankshaft and the flywheel - looks almost like a seal protector.

 

Contrary to the PC/ED, the engine will start and run without the crank sensor tone ring. However, the high pressure fuel test and KOER test refuse to run because it doesn't think the engine is KOER. The tach on the dash shows an RPM, but datalogger shows 0RPM.

 

Pulling the transmission is not as bad as expected - there is a video link in the workshop manual showing how to remove the starter that was quite helpful.

I mated the tranny and set the engine into the mounts before I realized the tone ring was still on the old long block.

 

luckily I didn't get as far a you but I did have to figure out how to dig a convertor nut out of the bellhousing in the process

Ouch- learning the hard ways sucks......
