Hi,
I have a four-cylinder chevy that I let sit for a year.
When I fired up the engine, there was this tremedous engine knock that sounded as if engine failure was happening. So I turned it off and cursed my bad luck
Six months later my land-lord tells me I have to move my li'l undriveable piece of junk because she has to tar the parking lot. This time I fire up the mutha and discover an engine knock that almost disappears when you throw it in gear. What happened to fiendish engine noise?
