| PECULIAR KNOCK TO ENGINE Posted by CHRISTOPHER GUSH on December 21, 2000 at 19:45:04:
I PRESENTLY OWN A 1995 LAND ROVER DISCOVERY WITH THE 3.9L ENGINE. I HAVE NOTICED AS OF LATE A LOW KNOCK WHICH APPEARS TO BE CENTRAL IN THE ENGINE ONLY AFTER OPERATING APPROXIMATELY 15 PLUS MINUTES. THE KNOCK DOES NOT INCREASE WITH ACCELERATION RPM AS IF IN THE BEARINGS AND I CANNOT ASSUME ITS A WRIST PIN DUE TO THE FACT THAT IT OCCURS ONLY WHEN FULLY WARMED UP. THE NOISE IS SUBTLE,YET CLEAR. I CONTACTED MY LOCAL DEALER INQUIRING IF THERE WERE ANY SYSTEMIC PROBLEMS AFFILIATED WITH THIS ENGINE AFTER 72K MILES WHICH I PRESENTLY HAD. THEY INDICATED NONE THEY WERE AWARE OF, ALTHOUGH THE SERVICE WRITER ASKED IF IT WAS A CAMSHAFT KNOCK???. I FOUND THIS PECULIAR. ANY THOUGHTS WOULD BE APPRECIATED. THANK YOU.
