Wilsons Sandbox

"""After purchase I was listening to the head knock and to avoid loosing position reference and perhaps banging my head on the bar, I placed one hand on the exhaust heat shield which changed the quality of the sound. I could hear a high pitched exhaust "spit" which was intriguing. Remove the shield and then not sure that the knock was a pronounced. Noticed that the exhaust flange was cocked at an angle, obviously someone tightened the right nut then put the left into place. Ratchet with extension, 1/4 turn and knock was gone!""" WHAT LUCK!! Good deal for you! BTW my oil at 3700 miles sheared from a 93 SUS to a 81.8 SUS viscosity, or a 50w SAE to a near 40w SAE viscosity. This was one of my main curiosities pursuing an analysis.
