Light, Grey smoke at Accel under a load
Hey guys, im driving my dads 01 F350 for right now. Unfortunately he is no longer here anymore and I am not familiar with diesels. I dont know if this is normal, but I just happened to notice the truck was doing a grey smoke at idle. Its was very light wasn't thick, and it only does it when stopped, and when I rev it, it puffs out light black smoke. I also noticed when I drove from lights it smoked a little. It has an exhaust, Edge Chip, and Intake. It still did it under normal operating temperature. I live in Arizona so it was around 106° today. I recently got my water pump replaced and the shop didnt say anything about knocking. When I floor it on extreme it billows dark grey but not full black smoke. Its not white from what I can tell. I want to make sure my dads truck is okay. Its my only connection I have with him. I never did notice the smoke at idle before and I was pulling a light trailor when it smoked more than ive seen it do today. I had it on tow. Also I am about 300 miles pass due for oil. If thats it I'm changing it right away. Also fuel filter isnt known when last changed. Hopefully nothing bbad.
