Not too much out of the normal. But number one was slightly scored up. Ant I found this. Plugged number 1 piston cooling jet. What gets me is I don't know what it is, or how it got there. I've done work/maintenance on the truck for the past 400k miles. Could it have really lasted that long plugged up? That is weird. Was the cooling jet plugged completely, or as you stated tubing, was there still some flow just reduced? I agree that I don't think it could have lasted for 400k miles with the cooling jet completely plugged, but I don't know. User's Signature: Why? Why do I always ask "why?" Because I can't learn or help teach others with "'cause I said so..." | |||
