Great News!!!!!!

I hooked it up to the IDS which can run realtive compression tests, power balance tests, and lots of other stuff. I ran self tests on the motor with koeo and koer to pull cmdts. It only threw one which was an over boost condition. I also monitored pids to make sure everything was where it should be. Everything was normal so I decided to put an engine ear on it. The knock was the worst on the right bank. I kept listening and started canceling cylinders. I pulled #4 and the noise decreased a lot, which tell us that is the problem cylinder. Its hard to say whether it started with a rod which led to the piston slapping around creating a slight double knock or whether the wrist pin took a dump. My guess is the rod went first. We won't really know more until we pull it apart.

just make sure you bore a scope the hole first It sounds like a piston issue.
Good luck


if you need to borrow a bore a scope we have one we will lend you to verify the problem before you take it apart

It might stay together that way.

That would be why I suggested it. They are not that hard to do. unless you are implying something different

Either way it doesn't matter I am not going learn anything I don't already know. The motor has to come apart anyway whether its a piston or a rod.

the offer is on the table good luck

I might be, just figured Id be a smart ass dick like everyone else.

Just a hint
If under power, you pull a coil and the noise goes away, it's a piston, but if it just diminishes, it's bottom end.

[Dan]

Well that was not my intention. As i hope personal stabbs were not yours

[ASUSMC]

Im just saying the motor has to come all the way apart regardless of whether it is a piston or a rod. The truck isn't going anywhere but in the garage for a while. Will probably start tearing into it this weekend.

[Ethan@S3M]

This will fix it!!!!!

It's better to pull the injector instead. If you pull the cop It will keep dumping fuel...no bueno
