    How much blow by ?

    I noticed my catch can had 1.5-2 oz of oil and gas it didn't used to have any. Checked compression 150psi on all 3 did a leak down looked excellent. I have been getting p0111 code faulty iat sensor I pulled it out and it had a tiny drop of oil on it ? Ski runs hard and afrs are dead on minus quick pulls on the throttle afrs drop to 10 for a split second ?

    yeah been doing a lot of dig runs bouncing the limiter a couple times out of the hole and doing some long wot runs @ 8600. i think slamming that limiter could be doing it ? i use to never check it because it wouldnt have but a couple drops

    Depends on air temps too and if your running open loop as well but ride on like eric said..... Its normal.... I drain after every ride in my catch can and I have a table spoon maybe a bit more.. All depends how clean your afrs are as well

    Air was 100+ and I'm running riva 158 thermo, I did another leak down but notice I had to set #3 tdc for the valves to be shut is this right ? I thought when the 4tec stops all the valves should be closed ?
