Which are the intake and which are the exhaust valves on a Mazda 6 RF7J diesel engine?

On the Mazda 6 RF7J diesel engine, the intake valves are typically located on the side of the engine where the air enters, while the exhaust valves are positioned on the side where the exhaust gases exit. The intake valves allow air to enter the combustion chamber, whereas the exhaust valves enable the expulsion of combustion gases after the fuel has been burned. It's important to consult the specific engine manual for precise valve identification and configurations.
