Oil coming from dipstick bulb

Postby dmellingson » Tue May 15, 2012 5:43 pm

I am curious about a recent development with my 154.

It has been sitting for over a year since I had purchased a new mower and now that I am finally back to showing the old Cub some love, she has begun smoking a little from the oil dipstick bulb abd the metal mesh in the bulb is fairly wet.

What is happening and how do I make it stop?

Air filter is clear and tractor seems to be running okay other than the blow back. More oil and blowback happen to more load there is on the tractor. Tractor is not over heating, radiator is clear and level is proper.

What am I over looking?

Please respond quickly, am a frist time user and am anxious to put the forum to use!!

Blowby, is caused by worn piston rings, where combustion pressure is blowing by the piston rings, and pressurizing the crank case, theryby blowing oil out the dipstick tube.

If the tractor sat for a year, there's a chance that the rings are rusted, and not wearing evenly, or a cylinder wall is rusted and not letting the rings seal, thus letting the combustion air by.

First step, go buy some Sea Foam, add it to the crank case oil, and to the gasoline (according to directions on the bottle), and run her hard for a couple of days.

Go mow with it, and put her to work. MAKE SURE THERE's THE CORRECT AMOUNT OF OIL IN THE CRANK CASE, and check it often. Sometimes this will help break up carbon and crud in the combustion chamber. If it does not clear up, you can keep running it, but eventually you will need new piston rings and an engine rebuild.

+1 as said above by gitractorman. Also . . . don't mistake condensation for blow-by. As mentioned, you have to get them out and work them for a bit. This gets them good and warm and purges the condensation out through the dipstick bulb but obviously will carry oil with it as it does.

I appreciate the rapid response! I have already purchased teh Seafoam and will add this evening. First chance to run the tractor good is Saturday but I intend to do just that. I will re-post the results and let you guys know how she is responding to the Seafoam. First time on a forum and am glad for this great tool!
