Upper valve train on a Elantra (bought brand new) always seemed to have a minor tick, sounded a lot like a bit of dirt in a lifter. A tap that you would have to know what to listen for,but nothing scary. I have used this product before, & its been good for cleaning some dirt or cam lube out of lifters,and lubricating the upper valve train. I gave it a try,and after draining out a quart of oil and adding Rislone the noise is gone. Keep in mind that its a good lube and cleaner but it can only be a stop gap (at best) for real problems.
