Could this old "timesert" thing be the source of low compression if it was incorrect? A couple of compression tests several months ago showed this cylinder low (can't recall the number, the rear one on the driver's side).
hello Roland there are a bunch of different plug inserts out there. They all work about the same. no compresion loss if installed correctly and head has no cracks. hole is not tappered and I don't know what you are calling a square seal? Plugs do have sealing rings on them and should be left on later mark d |
