[Chrysler300] Re: valve train oiling on my 392

["Chrysler 300" <chrysler300@xxxxxxxxxxxxx>]

Hopefully just caused by that gunk you found.  

Worst case guesses, Sloppy crank bearings -- and/or an improperly installed "oil restrictor". Thing was an inch or two in length, and the diameter of a drinking straw.

Not sure why they'd be necessary on a street motor, but some folks install these restrictor tubes in the oil passage leading up to the rockers. This restrictor thingy has two O-rings. The upper ring may bind during dry install -- then pushes back into the center area to seriously impede oil flow. The builder never noticed it, until we started over and pulled it all out. 

My '56 DeS had valvetrain racket and little oiling up top on a brand-new rebuild. Cam bearings and scuff marks looked normal, so we tore-down the motor and saw improper-sized crank bearings (ugggly wear) and the wrecked restrictor. These teamed-up to starve the hyd. lifters and keep things a bit too dry. Ran terrible.   With solid lifters, I never would have noticed 'til things really got trashed...

fingers crossed for you.  vath

  ever since i first fired my hemi ive had trouble with getting oil to the 
  rockers. sent it back to the motor shop to re-clean the rockers. found crap in 
  the oil passages not blown out after the hot tank. the dino went without a 
  hitch but after pulling the valve covers found valves sparcely oiled. going to 
  have it torn down tomorow first to see if the holes in the cam bearing is lined 
  up in the block and possibly sending the cam out to be turned so the heads 
  will get oil on the whole rotation of the cam. has anyone had this problem and 
  what was the remedy?
