Consult, what are the divers?

Hello friends, I have an Hyundai Accent 2002 and it turns out that this makes a noise in its engine when it raises its temperature (not overheat) I compare that noise with which they made the steam trains. I have consulted with a mechanic and told me that this noise disappears when changing the "divers" in the engine, but I have no idea what they will be and I would like to know their technical name.

Friend The divers are the taquets or raises valves are located on the valves in the camera I recommend you first that you will dare the oil and what time and mileage has since you changed it you have to measure the preservation of the oil to the engine which must be greater than 20 psi. hot, what kind of oil are you using?

Thank you friend for your answer, then look that the oil I do not have it in mind but is recommended by a mechanic, but since you mention that I think in the manual to ensure that it is recommended by the manufacturer. And with respect to the divers, also thanks ... I have taken me out of a great doubt.

Hey, do you know what is the technical name of the "divers"?

His problem is economically difficult because Nissan divers walk for $ 500.
