In my case yes I have a windage tray ,yes I may have overfilled the
oil pan, I do have a high voluum
oil pump with the optional shim installed. I haven't noticed any blow by before this incident. I think the proper
oil level and the Mobil 1 having an antifoam additive will take care of the foam problem . The valve covers filling up may be a fact . Probably did so when it foamed.
