sorry, i should speak more clearly. not a valve job, just a valve adjustment.

as for what caused the plug in the 1st place, i dunno. cheap gas and time coupled with a plugged egr system im guessing helped get it to the point of plugging. im assuming of course. but the egr system was clogged beyond belief, every runner from top to bottom and the intake runners had alot of garbage in there as well that i cleaned up, particularly on number 2 runner. besides, dont cats typically need replacing in the 100-150,000 mile range on these cars? they pretty much always do on the mustangs i deal with and my insight just hit 130,000 miles. so im chalking it up to age unless anyone else has some theories.

On modern engine, Cat life will be dependent mostly on the condition of the engine and drivers choice of driving style.
Mine has the original #2 cat after 300K miles and no problems.
Heavy lugging of the engine, as lots of throttle action with min. rpm, and a retarded ignition, which the Insight does all by it'self can lead to unspent or un ignited gases to accumulate in the cat. (EGR get clogged and the gases have nowhere to go, they can't be recycled back through the engine)
This has to occur over a large number of miles.
My opinion.
Need more history on your vehicle to give a valid definitive conclusion.

Only the OEM Honda ones. They are indexed. Check your head stampings.

BTW, if you are a student on limited income, I suggest staying away from turboing. forced induction gets expensive fast.

well, going turbo wont cost me anything actually, i have everything i need for the most part except the tiny 2" pipe that i would use. i usually cut out my own flanges and i have a meth kit laying around as well as a few fmu's and blow-offs as well as a tig and mig and consumables. the only thing i would need is the turbo and a buddy of mine will trade me a gt15 he has for one of my modded IHI's, so cost isnt really a factor as far as going turbo anyway. i didn't realize the cvt didn't actually achieve lean burn though, im new to the cvt as well as the insight. i guess that plateau i hit all of a sudden at 45 cruising when my mileage jumps way up is the tranny doing its magic. im no longer certain that a turbo will help the fuel economy any more even at low boost unless i tune with meth, but then gotta factor in the cost of meth which i know is way cheaper than gas considering the significantly less consumption rate that occurs only when achieving 2+ lbs of boost. i just dunno if its worth it any longer, in a MT sure, CVT???????

I don't feel like reading all the posts about emissions and how horrible you are for killing the environment (laugh) so I'm just going to post my suggestion.

On vehicles that I build and turbo for customers that live in emissions states I use Spark plug non-foulers on the o2 sensors to remove them from the direct stream of exhaust and keeps from codes popping up.

Autozone or any other parts store: Spark plug non-foulers, 18mm thread. 1 on each o2 sensor should be enough but you might need 2. I would start with 1 on the rear o2 sensor first, clear the code and drive to check if it stays away.

as a student on two different occasions i supercharged one car and turbocharged another, no money issues at all because it was planned and executed according to the plan laid out
