6.4 Blue Smoke
I have a 6.4 with a spartan 250 tune, and all deletes. I have noticed that every 10 or so start ups there is blue smoke when truck engine temperature is around 120 or so degrees. It smokes for maybe 30 seconds or so and then clears up. Cold temperatures is not really a concern its about 50 degrees. Runs fine cant tell no power loss or nothing like that just blue smoke. Has any one else ever had this same problem. Any help or input would be greatly appreciated thanks. sorry for being so long this is my first post. Just need some help.
