I recently failed for emissions, 3% carbon monoxide instead of 1%

I know my car runs rich and I know an air/fuel guage is pretty worthless.

After running a second slower at the track than I should be, I did a compression test.

180-230-235-240

Theory: Because of bad compression, the leftover fuel that should be burning in Cylinder #1 is going out the exhaust, therefore spiking my carbon monoxide and failing me.

Any thoughts? Ideas? I gotta swap in a clean sohc in my crx before the end of the month and I'm hoping this will solve my problem.

 

It could also be burning some oil, which is also a hydrocarbon, causing emmisions to go up. But you're right.

 

yea it def burnt some oil too, pretty weird for a low mileage Y7 block, but i beat the **** outta it. So im hoping an a6 block with my y8 head should work out good.
