The next step
Thanks for the info. Like I said the next step will be check the oil pressure both hot and cold. It only has 31000k but might have been riden hard and put away wet ? I did change filter when it was appart for the bypass spring but did not pay attention to the pleats (coolant in the oil).Still stumped about the noise going away with engine temp, you would think that as the oils becomes thinner things like the hydraulic assisted cct would leak worse and the noise would stick around to continue to irritate. Will keep you posted.
