Motor sound looks like an engine (diesel)

Good, I have a 1997 Suzuki Sidekick, I sent you to make a repair or rather change of the chain kit, and then the mechanic tells me that it has wear on the axis of Eleva that I found above, I need to know that I originate that, and if it has any solution. Note, now the chain kit and Eleva axes sound like a diesel engine, which can tell me

With the theme of the cams, check the oil light with a green plastigei sheet so you will know if the cams are spent if the measure is greater than 0.058 they are bad ... the chain changed the hydraulic tensioners and the guides of the chain .... Any Suzuki consultation helps you work with is brand
