NG engine knock

[Bill Green]

Problem solved! I went and bought a remote starter this morning so that I
could get a better view and understanding of just where the noise was coming
from. Turns out the starter was only held in by one bolt! It was hopping
around and making that god-awful racket when trying to start the engine. If
I hadn't bought the remote I never would have seen it. Thank goodness I
don't have to pull the engine again! 

This is not the dumbest mistake I've ever made 'fixing' a car but its close!
Lol

Hmmm... I'll double check the plugs. Although its only when  two or more
plugs are installed the knocking appears.

By the way I should have mentioned that the head / valve assembly is all
brand new as well when describing what I meant by "new NG engine".

Wrong plugs perhaps?? Too long? Maybe slightly tapping piston
