So it seems like the Protege 2.0 engines are pretty noisy little beasts... is it just mine or are your guys' pretty noisy too? Mine almost sounds like a diesel... I mean its not loud but just not a constant smooth engine purr... weird. I wonder if its the valves. Do they ever need adjusting or are they self adjusting?
Thanks...

 

The 2.0's are nice and smooth. Now the 1.6 are almost exactly like a diesel.

And there all very loud.

 

I see. My car has 150k miles by the way. Runs great, good power, just noisy when idling...

 

Mine runs smoothly, but it only has 46K miles on it. I don't know if the valves ever need adjusting, but I have never heard anyone advising to adjust them.

 

Yea mine purrs like a kitten after it warms up for a few minutes.
