I've got a 97 7.3 automatic with around 225k on it. I noticed that it's started to have a some what excessive amount of blow by coming from the crank crase vent. I was wondering if anyone has addressed this problem before or if anyone may know a common cause of this: broken piston rings, warn piston rod bearings, stuck valves, etc. Any info helps. Also if anyone knows of a good place to get a engine rebuild kit for a 97 7.3 that would be great.
