[DML] Re: front main seal leak

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

Possible causes of excess pressure in the crankcase:
Cracked, stuck, worn, or missing piston rings
Exessively worn valve guides.
Improperly adjusted valves
Plugged up or not connected vacuum hoses to create the negative pressure.
Pull the oil filler. Take a small piece of stiff card stock like a 3x5
index card and place it over the fill on the motor as the motor is
idling. It should stay in place. If it does not, you have problems.
