There is not really a oil consumption problem...it uses about a quart between changes. After the temp guage comes up, the truck runs fine but until then, just no power, and if you step on the gas, black smoke comes out. The fastes the truck will go until it warms up is about 30 mph. I have not noticed a whistle in the exhaust during this, but I will kill the butterfly when I get home and see if this works for in the morning.

Thanks for all yall's help!!
