""I have an Acura integra with a 2000 GSR Vtec B18c engine in it, ('94 body), the car runs but had a "knock in the engine", i have no idea what it is.. great for someone who knows these motors. This car is two door, charcoal in color, lowered, original wing, original tail lights, the glass is all good, Custom blue speedometer lighting. Really this car is very clean, has 68XXX miles on the engine, approx 120XXX on the body. $3500obo""

I am thinking to purchase this gsr.

I just want to clear things up. so if you start the car cold and you get a knock, its probably valves. But if its a constant knock, its lower end. Am I on the right track? I have rebuilt a motor after misshift but not after knock.
