Hello, I tried asking this earlier, but I chose poor vocabulary for the subject, so I will try again. I read in a thread on here somewhere that if someone does all the oil mods to their 455, including the line from the block sender-hole (don't know tech. name) to the rear galley, crank clearances should be different. I am not talking about the little line that people used to use to just connect the 2 rear lifter gallies. I will assembling a new short block soon. If I do run the line (rather abusive street use vehicle and daily driver), should the clearances be different than the .0015-.0020 for the rod/main journals? Thanx.
