Valve train is all tight (hyd lifters). Plugs on this bank (5-8) are all
oil fouled, 1-4 are not. Took headers off to inspect exh valves, could not see seat or valve heads, only end of guide, stem. Chambers coked up too much for 600 mi. #'s 5&6 have a very obvious
oil path comming out the port, actually dripping from # 6. Also cold cranking comp test is lower than previous on those two cyl.
Guess I'll pull intake and head.
