Consult, what are the divers?

Hi everyone, I have a 2002 Hyundai Accent and it makes a noise in its engine when it gets warm (it doesn't overheat). I compare the noise to the sound of a steam train. I consulted a mechanic and he said that the noise disappears when the engine lifters are replaced, but I have no idea what those are and I'd like to know their technical name.

Friend, the tappets or valve lifters are located above the valves in the cylinder head. I recommend you first check the oil and how long and how many kilometers have passed since you changed it. You have to measure the engine oil pressure, which should be above 20 psi when hot. What type of oil are you using?

Thanks for your reply, friend. I hadn't thought about the oil, but a mechanic recommended it. Since you mentioned it, I think I'll check the manual to make sure it's the manufacturer's recommended oil. And thanks again about the lifters... you've cleared up a big doubt for me.

Hey, do you know the technical name for "divers"?

Your problem is difficult financially because Nissan lifters cost around $500 USD. I checked some and saw that the fuel inlet was clogged with scale. The best thing would be to disassemble and clean them; it would be worth a try. Good luck if they work well. Sometimes it takes time to help the customer
