Speaking first to the oil problem.......
Overfilling is the likely cause, either from too much oil or fuel in the crankcase.
Severe blow-back from bad/improperly installed rings is also a possibility.
The absence of a baffle is also a possibility.
Now to address the troll issue.......
I was correct: as I predicted, "8N1949" did show up here again, most recently on Dec 13, 2013, this time w/ a new handle of "Pecan Okie". (see the link below)
He stayed away over a year and a half after he was outed here on April 19, 2012 as a military "poser", i.e., he was claiming to be a Navy fighter pilot w/ the Navy Cross.
We had put up w/ his incompetence, BS & rants long enough. We know exactly who he is.
This is my post from April 19, 2012 that caused his disappearance:
Are you the same Fred J Barner of Coffeyville KS, aka “skeeter” & “skeeterman” that got busted by the POW Network website for falsely representing yourself as a retired US Navy captain & pilot w/ the Navy Cross?
