White smoke and spitting oil?

I shouldn't be allowed to operate power tools anymore, but whatever... I was mowing my yard when I hit a piece of hidden wood. A piece of wood jammed against the side of the lawnmower and the blade, which required me to flip it on its side and dislodge the chunk of wood. After I removed the wood, I put the mower back into its right position and took a break (It's hot out..). After my 45-minute break, I went to start it to finish cutting and it was belching out white smoke, and leaking and spitting oil out of the muffler. My father and I took a look at it finding nothing, but I took off the air filter cover and there was also an oily residue in there, more than normal. What could be wrong with it?

P.S: Comment if you want pictures.

I had a whole tank of gas drain out of my timemaster while sitting in the garage for 2 days. I added gas and it barely started, then cut off after 20 seconds. It started a few other times for a short period, then blew out white smoke and drips of oil from the exhaust. What could be the problem here?

I have a craftsman Lt 1000 with a 16.5 hp briggs and stratton engine. I adjusted the valves and now the engine is smoking (white smoke) and blowing a little oil out of the exhaust.

Carburetor shut off not working. Drain the oil, pull the spark plug and let the gas evaporate. Put an inline shutoff on the gas line

I bought used craftsman LT 1000. Fixed carb and adjusted valves adjust ignition coil but when inStarted it , it started to smoke blueish and whitish smoke out of exhast burning oil. I thought valve seals but i opened air cleaner cover and saw oil in the air duct housing of carb i started again and saw that oil is being pushed out of pvc breather , crankcase breather . Its just at the top of carb under the flywheel housing. The pressure its spraying with is like a high pressure tap . I pulled off the rubber pipe from both sides carb and engine side and see oul layong in that long path. What causes that and what is a the quick or proper fix for it. If i routed that cranckcase breather pipe back to shoot back in engine oil housing oil pan side from dipstick or from oul drain plug side Will that cause some major problems? Also is it normal for the engine to blow outwards the oil if dipstic is pulled from the engine? I never had riding mower before never worked on them but i was an auto mechanic.

Skippy, when you flipped it over, you drained engine oil into the cylinder. If you let it run long enough, the oil will burn itself off.

Or, you can remove the muffler, drip the excess oil out of the engine, clean it up a little with WD-40 and a rag, reassemble it, and start it up again.

It may be a good idea to remove the spark plug and either clean or replace it. If you can clean the air filter, do that also—or replace it with a new one.

Good luck. Let us know how it goes.

Thanks dude, it's not spitting oil anymore and no more smoke

by

Cool. Next time you have to tip it up again, put the carb side in the air and you will avoid the smoking again.

by

Uumm, do you mean the muffler side? I had the carb side up in the air when I did this (the muffler was pointed down towards the ground).

by

Ok so same thing has happened to me. Brand new mower, used only for 2 Yrs. white smoke is coming out of it big time!!! Now it doesn't want to start.

by

If it's 2 years old, it was brand new 2 years ago. Now it's 2 years old, which is quite far from brand new.

by

He mean to say that it is only 2 years old since he bought. Though a lawn mower may not last a life time it should definitely last more than 2 years. The issue is that the lawn mower may have tilted while you were mowing and too much oil may have come out to the filter. Open the filter and clean it up or replace it and also replace the spark plug and you should be good to go.

I have oil pumping out of the crankcase vent tube into the carb which makes a big plume of smoke. I had tipped the engine over to get the oil out to change it.

I bought a use mower from a guy and the mower did not have but a little oil in it. I put oil in it and started the mower and the mower started blowing white smoke and I have oil pouring out of the mower, can anyone tell me what just happen. What do I need to do to stop the oil leak and the smoke.

by

The oil is leaking by rings on piston or you added to much oil.

I have been noticing puffs of white smoke and obvious distress of the power of the Briggs and Stratton on my Toro engine as the oil is sucked into the engine on a bend or slope, it lasts for a couple of seconds and clears up. I did a check on the oil level and found it to be too high. Odd that, as it was okay in the summer. Just tried again today (the grass needs a cut despite being January) after not using the mower for a couple of months ( did not drain out the fuel for the winter) and could not start the thing. Huge puffs of white oil filled smoke from the exhaust, but not quite starting. Checked the oil and found it was no longer oil but mostly petrol / oil mix and way too full. Drained out the oil and replaced it and ride on mower started first time with oodles of white smoke burning off for a while. Trip round the garden and all well as far as the engine is concerned. Just need to solve how petrol can transfer directly into the oil sump. There is no stop $!^& on the fuel side so perhaps the float valve has stuck open and petrol has been dripping into the engine and passing the rings. Any ideas?

All well with the engine. A new float valve assembly in the carb and seems to have cured the fuel leak. The fuel does go down into the crankcase ( weird design issue) when the float seal fails with wear. Added a stopper on the fuel line as well to be extra certain. New head gasket and cleaned out the very carboned head and piston top and replaced the spark plug. Set the tappets and all runs sweetly now.

And Does a lawnmower take the same kinda oil a car does

by

the kind of oil you need should be in your owners manual and the type of oil needed is based on the outside temperature.

If your blade hit a big/heavy rock and stalled it is possible that you have a bend crank.
