What happens if Valve clearance is too big?
The valve clearance of diesel engine should be checked frequently. Too large or too small clearance will affect the correctness of valve timing and the tightness of the valve, and even cause the damage of the whole valve transmission mechanism.
Can I drive with bad valves?
Unfortunately, yes you can do more damage by continuing to drive with damaged valves. Damaging the catalyst can cause it to break apart internally, leading to plugging up the exhaust and causing an even more severe loss of power, which will make the car very difficult to drive.
