I know these engines have valve noises sometimes after 100,000 miles, but mine is wierd.
Some times it makes a very loud tapping noise like the whole F'n engine is coming apart.
Other times it runs so quiet its like brand new. NS.
This vehicle has 128,500 miles on it.
Do you think I need a new engine? Is this engine likely to STB and leave me stranded? Or do they go like this forever with no problem other then the tapping noise?
thank you,
