A few questions
 

Looking for some info on my truck. Its a 2000 7.3 reg cab auto with 137,000 on it. I am the second owner of the truck and it was bone stock when I bought it and has never towed a trailer or plowed snow. The truck is super clean and has never worked a day in its life. The only mods on the truck now as far as performence mods are a 4 inch down pipe, and a 5 inch straight pipe which exits into 6 inch dual stacks, I just recently installed a AEM intake and noticed some oil inside the intake piping and was wondering what this could be cuased by? Also when the truck is warm and you pull the oil filler cap, a small amount of smoke will come out, and lastly when you start the truck up, it will smoke a little and then clear up soon after. I also purchased a Ts 6 pos chip for the truck but have not installed it due to these disconcerning symptoms. The truck runs good however just recently over the past year begain to show some of these symptoms , just wondering if anyone would know what this is caused by? This statred soon after I switched oil brands from rotella to motocraft, any info is greatly appreicated.

Oil in the intake is normal for the factory CCV set up. Nothing to worry about...

Blow by is normal for a diesel truck, so long as you dont remove it and say "WOW" then its nothing to worry about.

The smoke at start up could be normal, could be a glow plug or three that are bad. Again, nothing to worry about.

Thank you for your imput, just making sure there isnt a problem which needs to be addressed with it, again thanks for your time.

All sounds normal for what info I have. :tu:
