Ford Lehman

All you Ford Lehman owners I need your help. I have a FL 120 and have developed a oil leak and for the life of me I can't figure out where it's coming from. The oil leaks out of the bottom of the starter solenoid. I've inspected the upper part of the engine and she is dry. I did find a piece of foam stuck between the starter and the solenoid. It leaks more with the removal of the foam. The leak is about 1 pint every 70 hrs. Any suggestions. Thanks for all your help.

Greetings,
Mr. Gb. Haven't got a clue BUT could it be your main seal is leaking and the oil is being flung about by the flywheel and the starter motor is the easiest leak? Is there any oil on the bottom of the bell housing?

I've not see the back of the engine under the bell housing, yet. But maybe there's a oil gallery plug that's leaking?

Lehmans have two starter solenoids usually.

My Lehman has the normal one attached to the top of the starter like 99% of all states and a second one maybe 6 inches in front of the starter, mounted to the lower engine block.

There are Lehman starters with the second solenoid also attached to the starter If I recall.

Can't speak for oil leaks on the last I described, but with my engine...the oil pressure sender is right next to the stand alone solenoid and oil drips from it sometimes, though the actual oil seepage is from the sender area.

Without pics, really hard to help.

Could be oil pressure switch. When they get old, they leak at the top where the wire connector come in.

Why do Lehmans have two starter solenoids anyway?

Oil leak

This is the area in question. The black rubber was inserted into the slot.

Oil leak

Sorry for the additional post. I thought I submitted both pictures. I'm a newbie to uploading pictures.

So far, IMHO, Firefly submitted the more logical cause. I had this same issue though not through the starter area, but a rear main leaking. The oil is slung with great intensity, makes sense that a path of least resistance as the main seal being the culprit. Keep us advise when you do have a actuate determination. We all can use results of inquiry such as yours.

My Lehman SP135 oil leak was associated with a lightly leaking valve cover gasket. Leaked oil was first noted in the area of the aft port engine mount. The leaked oil from the valve cover followed a hard to detect path which passed in proximity to the starter. Just a thought. Good luck.
Cheers,

Check your lift pump gasket. Amazing where the oil gets to and it's very common.

Yup. Had the same issue. I replaced the gasket and started all over. Try not to over tighten though. It will leak. The book says 12-18 ft. lbs. torque.

Well, they solved my issue. I was using the dipstick factory Mark for oil levels. No one warned me upfront that since the engine sits in a tail down angle the original factory Mark is no good. I was overfilling. Appears the common sense gene was dormant, so Bryan had to tell me.

I did as he suggested. Emptied All the oil in the engine..bone dry. Then I put in the factory reccomended 14 quarts (as I recall). Then pulled the stick and filed a new Mark on the stick.....there, problem solved....... Thanks Bryan.
