Hello all, so I finally started my new engine today, first time ive ever swapped an engine and I was thrilled to see it start with minimal effort. I have a new long block, new injection pump, new injectors, and oil cooler. I also did the upgrade to the electric fuel pump, added a bypass oil filter and 3" downpipe with 4" straight exhaust.
It fires right up with just a flick of the key oil pressure comes up quick (oh yeah all new gauges also) I know I am a little off on my TPS sensor because its a little slow to shift but the more pressing issue right now is I am getting a pretty decent knock. the knock was not there when I first pulled the truck around the block. I then took it for a spin and got up to a bit higher speed. As soon as i did i heard a knock start and it has not gone away since. It doesnt knock at idle but starts around 1000 rpm and its speed changes with the rpm's.
I am just guessing but could this be timing related? I advanced the pump about one dime worth and it didn't seem to make any difference in the knock. A couple other things are it is smoking whitish grey smoke pretty consistently and it idles a little rough.
Any thoughts on what I should try next would be appreciated.
Thanks
