I was looking at 06 f250 with 6.0. It had aftermarket exhaust and air intake. I started it up and a little smoke came out exhaust. Is this normal?
There was a whistling noise coming from the exhaust. It would go away for a few seconds and then come back. What exactly is that noise and is it suppose to be constant?
My budget is 26k. Should I be looking at 6.0 with decent mileage or 6.4 with higher mileage?
That whistling noise is the turbo veins opening and closing. This is written into the program of the truck to keep the turbo veins from sticking on trucks that idle a lot. Not supposed to be constant! Normal.
I would stick with a good clean 6.0 personally, but do have a slight bias
As far as other things are concerned you will need some sort of monitor. As GAUGES ARE A MUST ON ALL 6.0s you are going to need one anyway so go ahead and get one and hook it up to the truck on the test drive. You will want to get the truck up to operating temp and then cruise on the highway at 65. The delta (difference) between the ECT (engine coolant temp) and EOT (engine oil temp) should be 5-10 degrees. If it is higher than 15 you are going to need a new oil cooler and EGR cooler/delete. If the truck proves to be good take car of it and it will take care of you.
Remember MAINTENANCE IS CRUCIAL!!!! Synthetic oil and regular fuel filter changes are a must! And I would go ahead and flush out whatever coolant is in there with a CAT EC-1 Rated ELC.
As you are new to all of this you have A LOT to learn. Just focus on getting a good solid platform to work with first and then we can talk all the details. If you have any questions please feel free to PM me!
