Man... what an oily gunk mess. I didn’t have any problem getting the engine pulled, seeing that 5 of the 6 bolts were only finger tight. This is not the first time I’ve found loose bolts there. Is this something that happens or am I just lucky.
A29B5706-AB9D-4EF8-B8DF-D9CE20B8789F.jpg I’m finally in to the flywheel side seal. I’m not completely convinced it’s the seal leaking. I’m thinking it looks more like the timing cover gasket, or the crankcase breather vent. The seal is pretty dry except for the oil soaked grass gunk you see in the pictures. Look at the left side when looking at it from the flywheel end it looks wetter. See photo evidence: 8A198160-085B-4141-94B2-930968168728.jpg 4A272722-5263-4ACB-81F7-F89B0008C4D4.jpg D484D380-84F3-4AB6-989B-71A837764284.jpg 35D876A1-8C04-4DEF-83E6-630D023FFF96.jpg 5139B357-8A11-4A12-A617-5B5BC3CD1A5A.jpg 9EFB8D90-85AA-4B16-9487-7256B3D69FB0.jpg Last thing, I see in the manual that the condenser is under the points cover, mine is external and attached near the coil. Does this matter? 8CC723D2-B4D3-4DE2-83F7-0318838C669E.jpg

Regardless of how the seal looks it would be foolish not to replace it.

I’m planning on it while I’m there. I just am trying to figure out where the leak is from. I don’t want to replace only the seal and still have a leak either.

Possible Solution!
I think I have figured it out... I took the crankcase vent apart and found some dirt inside, and the gasket was cracked and brittle. I am pretty sure this dirt blocking the drain hole in the vent is why the PO blocked the tube and removed the vent tube from the intake because it was allowing oil to back up in there and get forced up the vent tube, and where the oil was leaking from. So, I am going to go over both valve covers and replace the gaskets, and replace the seals while I have it apart, and we will see what happens. Also, I noticed I am missing the tube that goes from the fan shroud up to the intake, is that an issue?

Sounds like you're getting the problem solved. I'm pretty sure you need that tube because the fan blows a good bit of air up into the air cleaner and without it the engine will run too rich. There was a guy on another forum that was missing that tube and he couldn't get it to run properly until he installed one.

they are also known to suck air through the split intake manifolds...Replace that gasket and use sealer.... It will surge if you have a leak....

The tube running to the air cleaner is there to supply cool air to the carb, without it the engine will be sucking in hot air from the top of the engine.

$50+ for a new air intake tube...
 Hopefully I can find a decent used one...

The more I think about it the tube probably isn't a necessity, the Kohler KT and magnum's don't have them.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
