I failed the emission test on my truck w/ 22r-e. The engine is completely rebuilt with new piston and rings and honed/scratched cylinders. I put only 300 miles on it before doing the emission test and the HC value reached 300 ppm (200 ppm is the limit in Sweden). What can I do?


>>>*One thing to remember is high hydrocarbons simply means unburned fuel. A 300 PPM reading is actually very low, that is the limit in our State of Oregon for older vehicles.

Then consider that you have only 300 miles on her, a good long brisk run to fully seat the rings is helpful. Bores that are simply honed often take a thousand miles and sometimes more to seat fully due to minor imperfections.

So before you do too much, I would run the engine more and see if it doesn't just cure itself....*EB
