Your question is to general to give a definitive answer. Need more info. When does it knock? Does it knock if you rev the engine? Does it only knock under acceleration? Does the knock seem speed related? Does it knock when the engine is cold or hot? Generally knocking is not a good sign. But there are still variables.

no columbus ga will get it seen about but was just wondering if it was worth the time ? i mean if it is serious it is too old to fool with lol I am a female that knows nothing about cars lol ugh just have a feeling it is bad news


knocking in the motor cannot be good right ?


contact Dick Hussey at and ask him if he can recommend a mechanic in your area. Dick can give you an idea of possible costs and if they are justified or not. He eats, breathes and sleeps Allante's and has Many of them and a gob of parts. Aside from that - when these things are running good - they are a blast to drive around in.
