cold engine knock

RE: cold engine knock
Bearing knocks do not go away as the engine warms up. What you are probably hearing is either valve train noise because of a sticking lifter, or piston slap. These are not really bad problems, but you should let a knowledgeable mechanic check the engine out before spending money, as it could very well besome other more serious problem.As was said many times before, it is very difficult to diagnose problems from someones noise description. As was said above, look for one that has no problems to start with.
