Quote: I'd just run another breather like you have on the other valve cover. That it has that much oil around the grommet makes me wonder if the one breather is enough. Does it seem to have a lot of oil residue around the breather and other areas? Reason I'm asking is I've seen some motors glaze the cylinders from improper break-in, but the leak down test kinda rules that out. Where was the piston when you did the leak down? TDC or BDC? Not that it matters, just thinking maybe the rings are sealing where it was tested and not elsewhere. Does it seem to have excessive blowby?
pistons were at TDC. haven't really looked for excessive blowby, although you would think that would have occurred to me me by now
