I drive over 20k miles a year so I appreciate the time and advice as I'm sure you're helping a lot more novices than just me. I'll reply back with results.
Brakes work fine and will be replaced next month with ceramics, plus new rotors. Do you recommend any other?
As for the PCV valve. I have a breather filter in place. Is this the same or are you referring to something else? Would Sea Foam alleviate anything or is it a temporary fix?
