long story short I bought an 01 24v with 300+ miles had a bad misfire it had a month old vp44 hot rod pump and air dog it seemed like injectors out a brand new set in ran a lot better but still a lot of blow by and white smoke and misfire but not near as bad, when I pulled valve cover and ran it blowby was coming out of the 3.4,5 ex valves, so I pulled the head didn't see nothing obvious wrong rings looked fine only noticeable thing was that yhe 5,6 pistons looked dry compared to the others here's some videos any advice will be appreciated
