The biggest problem with lean burn is that the oxygen sensors are prone to failing. I have probably had dozens of CELs in the three years I have owned Chorizo. I replaced the oxygen sensor and still have the light come on, just two days ago, in fact. It is $400 from Honda, $173.97
here and $140
on Amazon, but prices fluctuate.
The next weak spot is the aluminum oil pan. Non-DIY people insist I stripped mine by not taking it to a teenager with an impact wrench, but I never had a chance to over-tighten it, it never got tight!
For the aluminum pan (and perhaps even steel ones), please consider
http://www.qwikvalve.com/. I can remove the oil filter from above the engine and can flip the Quikvalve without raising the car, so I can change the oil without tools!
