Hello GS300 owners:

One of my customers brought his car in with an engine knock on #1 cylinder, on acceleration--it sounds like a rod bearing. The car has about 65 k on clock. Not sure all the oil changes have been done--he says yes, they have. Has anyone out there had any problems with this engine?

Thanks!
