Help! I have adjusted the valves several times on my m20 at the eccentric and the cam. My valve noise is still super loud and it has quite a prominent misfire at idle. I have tried 0.010 and 0.008 clearances and nothing really helps. I have 20w-50 oil and the car has about 212k miles. Not sure if the head has been rebuilt before. I don’t want to drive it the way it is but I really don’t want to throw parts at it if it can be fixed without any. Any ideas? Also has a knocking sound when you rev the engine. I wish I could post a video but I’m not sure how lol

With that mileage and an unknown history you could easily have worn eccentrics, cam and or rocker faces any or all of which could cause clearance issues.Seat Shocks....I have passed the baton to John Christy from Ninestitch. Email John or Garrett at ninestitch1@gmail.com
