stevebo-(Moderator) 8,059 #1 Posted April 28, 2014 All- I recently picked up a really nice Lawn Ranger for my son at my meet and greet. It runs awesome but when mowing on uneven ground oil pushes out of the breather tube. At first I thought it was due to overfilling the oil since I just replaced the oil today. The oil level is correct. Can anyone shed light on this besides the fact it is a tecky?? lol Share this post Link to post Share on other sites
Martin 2,130 #2 Posted April 28, 2014 Steve, does it have some sort of filter or baffle that should be on or in the breather tube? most engines have some sort of oil control or drain to stop oil exhaling with crankcase pressure..... not familiar with teckys........

groundhog47 347 #3 Posted April 28, 2014 (edited) Check page 87 of this manual: I got one in for maintenance one time almost sme prob, some one had mounted crankcase breather upside down and oil would not drain out once entered. Don't know which engine (6hp?) it is but prob near alike on all, even B&S has an upside down. It's even tougher to determine with inattention on multi piece breathers. Also:from manual.. BREATHER PASSING OIL 1. Check the oil level, make sure the engine is not overfilled. Also verify that the viscosity rating on the container of the oil being used is to specification. 2. Check the angle of operation. Avoid prolonged use at a severe angle. 3. Check the engine R.P.M. setting for excessive R.P.M. using a vibratach or other tachometer and compare it to the R.P.M. settings found on microfiche card # 30 according to the engine model and specification number. Adjust the high and low R.P.M. as necessary. 4. Check for leaking or damaged gaskets, seals, or "O"-rings. External leaks may not be evident; however, the leak may prevent the engine from achieving a partial crankcase vacuum. 5. Check the breather for damage, dirty condition, or improper installation. The oil return hole(s) must face down. 6. Check the engine compression using a compression tester. If the engine has weak compression, determine the cause of weak compression: worn rings, leaking head gasket, or leaking valves. Follow the compression tester's procedure Edited April 28, 2014 by groundhog47 Share this post Link to post Share on other sites

stevebo-(Moderator) 8,059 #5 Posted April 29, 2014 The only thing I can see is the tube is a little loose but facing down. Not sure if it should be tight or not. Share this post Link to post Share on other sites
groundhog47 347 #6 Posted April 29, 2014 The only thing I can see is the tube is a little loose but facing down. Not sure if it should be tight or not. Not that tube is upside down, but holes in back of breather assembly facing crankcase. They should face down. Rubber tube loose has no bearing unless so badly hardened won't seal The only thing I can see is the tube is a little loose but facing down. Not sure if it should be tight or not.

buckrancher 2,678 #7 Posted April 29, 2014 (edited) steve check the tube to besure a mud wasp has not plugged the inside of the tube I had that happen once Edited April 29, 2014 by buckrancher 1 Share this post Link to post Share on other sites
groundhog47 347 #8 Posted April 29, 2014 I have two teckys that do the same thing Check to see if inside of breather is upside down. It has bleed off holes, that if not facing down will allow breather to collect oil enough to blow out tube, doesn't matter if tube twists around or not or upside down except would fill with dirt and poss water.
