Default 169 leaking oil

Good evening all. Seems that the 169 has developed an oil leak as of recent and I'm not sure how it came to be or what is causing it.

In the first pic it is welling or weeping out of circle in the block that my finger is pointing to.

In the second pic it seems theres an additional leak at the gov/throttle linkage. You can see a drip at the bottom of the linkage. Its a steady leak and it's leaking onto the points cover.

Please help!

Ps I forgot to add the only thing I have done was remove the OEM breather and guts and install the Kirk breather with a new gasket....were some of the guts supposed to remain?

You did something wrong. Either you installed it wrong, or something. I am certain that changing the breather is the source of the leak. Your crankcase is pressurizing.


I don't know why you need a different breather anyway. The original style is fine. Just put it back on.

My mechanic put it on when he installed the new cork gasket for the hydro but that's what I am thinking. I know the breather is getting the pressure out as I feel the pressure at the end of the hose but yeah it sure is weeping alot. I'll have to take it off myself and reexamine. I bought the breather along with the points saver, ignition coil and wire from Kirk

Point Savers are a waste of money too.....

Points very seldom wear out. Plus, setting timing is easy and only needs to be done if you A.) Filed the points. Or B.) Replaced the points, or otherwise removed them to work on the motor.

So your "mechanic" recommended these aftermarket parts, or you had him install them at your request?
Either way, the original factory breather and points were proven for many years as working fine as is/was. Waist of money to me, but it's your money, your tractor.

Since the guts include a reed valve and a filter, the guts should have remained when the cover was replaced. The Kirk cover just redirects the breather gasses down below the engine so any oil that is in the gasses does not collect on the side of the engine and then collect dirt and debris on the side. Just the cover should have been replaced, and all the guts should have been left in place as they all have a purpose. Without the guts, the engine will suck some dirt and debris into the engine during the compression stroke when there is a slight vacuum created in the crank case. The reed valve should prevent this. The filter will collect some of the oil in the gasses and redirect it back into the engine. I am no expert in these engines, so I am sure someone will chime in and set both of us straight.

Maybe the new cover restricts the airflow from the crank case enough that it forces the engine to find worn parts to breath through. Putting the old cover back on should confirm this.

Well, the logical question is...(drum roll please)....(pause for dramatic effect).....

Did the oil leak start immediately after the repair work or has it been like 6 months and then starts leaking? Your opening statement alludes that the leak appeared and increased over a period of time.

How long would an INCORRECT breather installation take to start pushing oil out?
I don't know either, but I would tend to think that it would be sooner rather than later.

I would attribute this to the breather. I just had the breather installed and this was the first time running it since installation. Something isn't right and causing blow by

The guts need to remain. Kirk site (www.kirkengines.com ) calls this a breather cover.....not a breather replacement.

Try installing the breather guts first. Make sure the drain hole in the OEM breather assembly is towards the bottom. While you have the breather assembly open it would be a good time to check tappet clearance.

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.
