Hyundai Other

My son has a 2000 Elantra and the valves are clacking like crazy. Are they adjustable or hydraulic? If so, what are the clearances and procedure. I will make a donation as soon as I get paid. Please trust me on this. I am on Social Security Disability and I am broke at the moment.

Don't give what you ain't got!

The valves are hydrolic. This is an interfernece engine : shock:
