the car is a piece of junk. 200K + miles, and a rebuilt wrecked salvage title from another buddy. hes not looking to fix it up. In fact its probably "totaled" for anyone who isnt a mechanic. Its just to get him through until
he purchases a real car.

I understand the misfire detection process at work in modern engines. Im not ,however, familiar with adjusting the valves on a Honda engine. Is it similar to the procedure of adjusting valves on, say, older chevy engines-tightening/loosening rockers?

Here in atlanta, actual tailpipe emissions are not tested on OBD2 cars.
Only the computer is read for problems, hence check engine light on= no tag.

And a more general question. How would tight valves leak compression? I've always heard that, but could never wrap my head around it. Seems like tight valves would = higher compression.
What am I missing?

Thanks LATECH!
