Hi, I have a 2005 Auto FWD Pontiac Vibe with 214,000 miles on it. I've only had it since 180k miles or roughly 2.5 years ago. I've done transmission filter and fluid replacement, coolant flush with thermostat, multiple engine oil changes, fixed tensioner leak. Car runs great, I get up to 33 mpg when I do almost all highway driving, engine sounds good as far as I can tell. The owner's manual said to check valve clearances at 120,000 miles, if someone followed the manual I assume that was done then, hopefully.
If the engine seems to be running fine, no engine light, no misfiring, do I need to really check the valve clearances or is the VVTI system good enough to keep that in check? Is there anything else I should do to keep this thing running besides oil changes and checking fluids?
