Question about Troy Garden

Open Question

Troybilt tb4SC I'm working on one of these for a friend and his blower is blowing oil out the breather tube. What needs to be done to correct this problem? Do you have to tear the engine down and replace the breather tube? When I look on parts lists for this blower, I don't see a "breather tube"

SOURCE: Blowing oil on an 8HP craftsman snowblower

That is a breather tube, I can't picture the motor off the top of my head but that tube is either connected to the valve cover or if the tube seems to go up over the motor then that tube goes down into the motor. If it's the one thats connected to the valve cover then it's possible there is to much oil in the valve box. If it's the one that seems to go up over the top and in then if your just alittle to much over full you'll get oil out of that tube cause that tube sits alittle above the oil level.If your oil level is right on the line then I would run it for a bit then check the oil level. If the level is still good then you should be ok but keep an eye on it if it continues to blow oil out I would take it in to get looked at futher.

SOURCE: What type and grade of oil is required. I have

Any 2 cycle oil will work. Then mix 1 gallon of gas to 1 container of 2 cycle engine, shake well and pour into your blower.

SOURCE: What type oil do I

Your user manual would tell you exactly what to use, if you have it. If you need a manual you can download a free one here, but you will need the serial number of the machine in addition to the model number.

SOURCE: valve breather shots out oil when engine is running

I do not think this is a gasket issue, if the machine has beed tipped up oil will travel up the breather tube and enter the air filter case, over filling will also cause this, if its been tipped it will clear if you run it for a time with the filter off.

Oil leaking from breather tube on my 1991 harley davison heritage soft tail on first start after four year storage


The engine "sumped", meaning the oil in the oil tank leaked past the check ball in the oil pump and is now in the bottom of the crankcase. Place a pan under the breather tube and run the bike until no more oil comes from the breather. keep an eye on the level in the oil tank. You don't want to run it dry. If you added oil, chances are the dipstick will fly out due to too much oil pressure. When you're done, either change the oil and filter, or add oil to the tank.

Your oil breather (on the side of the engine opposite the carb) may be malfunctioning/defective allowing the carb to **** oil from it. There is a breather tube that crosses over the top of the cylinder connecting the crankcase( oil) breather to the air filter housing. Check the oil level and the condition of the air filter and esp. the oil breather. It serves the same function as a PCV on a car engine.

I had the same problem! I found that the needle valve in the carb was not shutting off the fuel flow when not running. Either replace needle valve or put a shut off valve in the fule line. Should take care of the problem

Oil blows out of tube


You either have a head gasket going bad or your piston rings are shot which causes air to go down into the crankcase building up pressure which exits through the breather tube.
