Why is there blue and white smoke everytime I turn it on?

I will be mowing my lawn and turn it off so I can empty out the bag and when I go to turn it back on there are big clouds of blue and white smoke that come from it. Also it will spray out hot oil....

I went to try and find out what the problem was today and I had read something about the fact that it could be the bottom is filled with too much debris so I tipped it onto its side to inspect it and then I tipped it back oil was leaking thorough the filter on the side.....

Chosen Solution

When you turned it on its side you allowed oil into the cylinder.

Blue or white smoke coming from your engine usually indicates burning oil, which can be caused by:

Overfilling the crankcase with oil

Incorrect oil grades

Operating engine at greater than a 15 degree angle

Inoperative crankcase breather

Crankcase air leak

Blown head gasket

Worn cylinder and/or rings

Turning/tilting the engine on its side for storage, oil change or any other reason.

Note: If the engine has to be tilted, ensure the spark plug is facing upwards to help prevent oil from escaping the crankcase.

Other reasons for blue or white smoke from engines include going over the engine’s oil capacity, an obstruction in the breather tube (located behind the air filter), damages to the cylinder/piston rings, and more.

Engine oil capacity is dependent on your specific engine model and can be determined by checking the Oil Recommendation FAQ. You can also learn how to check the oil level and change intervals to ensure the engine is running at the correct oil capacity.

How to Troubleshoot Engine Smoking

If you wish to troubleshoot and repair the small engine yourself,

Step 1: Are you tilting the engine or using it at more than a 15 degree angle? Tilting your mower or equipment can cause leaks. Right the machine before moving forward.

Step 2: Checking and changing the oil is an easy troubleshooting technique for this problem. Check to see if the oil is overflowing or you’re using the wrong grade/type.

Step 3: Check the crankcase for leaks.

Step 4: Is the head gasket blown?

Step 5: Are the rings and/or cylinder worn?
