1997 chevy lumina 3.1L valvetrain rattle/noise?
I have a 1997 chevy lumina with a 3.1L OHV engine with 103,000 miles on it. For about the last 20,000 miles or maybe a little more i have been noticing a rattling sound and it sounds like it is coming from the valvetrain. I have taken it to several trusted and reliable mechanics that say this is normal and i do not think it is especially since it is an OHV engine and should run quieter. What could be wrong and how could i fix it. I would like to do it myself as i am pretty mechanically inclined.
Thank you
