Re: What is this Knock? (with video)
How many miles have you driven it with it making the noise?

Why is it that there's seldom time to fix it right the first time, but there's always time to fix it right the second time???
That's not an oil leak
That's SWEAT from all that HORSEPOWER!!

Re: What is this Knock? (with video)
I removed the fuel pump , some light noise went away but the deep one is still present. To answer 70F100 question , the truck has had the knock for about 4-5 years and I'm guessing at least 900+ miles. It was also has done some extreme use either through big loads or high speed. If it goes I guess I'll just have to put in the spare.
-Maybe an unrelated note , I ran sea foam through the truck and it knock bug enough chunks of carbon loose I could he it clatter through the exhaust. It also made really really good smokes rings while idling.
