So I finally got my truck back together after tearing it apart and putting remanufactured cylinder heads on it... The truck seems to have some hesitstion/studder when accelerating and burns oil on startup & higher rpms (blue-ish smoke). I'd guess valve seals are bad, but the heads were just cleaned up and they were supposedly replaced... (The company messing up is always a possibility). I compression tested every cylinder and the rings seem to be fine. The sparkplugs had a light coat of oil around the tips and I'm definitely down a good amount of oil after test driving it a little. Anyone have any thoughts or adivce? I also performed the turkey pan mod & installed a catch can, and trick flow valve covers (I read somewhere that these have some issues with PCV for some). I also hooked up my Modis to monitor the cylinder contribution when driving, and every once in a while there seems to be a small misfire, but not very often and it's not throwing a code.
