Oil leak engine

Recently, I started the tractor and smoke was coming from the front of the engine. After looking around, I noticed that oil was seeping out from one of the welds on the muffler. I pulled the dipstick and there is definitely gas in the oil. Before this issue, we were having problems with the engine dying for no reason after it had been running for a while. I found out it was flooding because it would start again after it sat for a while. I'm guessing this is a carburetor problem, but how do I fix it?

the engine is not getting enough gas. when you hold down the primer you are bypassing this problem. to fix this simply adjust the carb's fuel screw, located on the side of carb, a little at a time until runs smoothly.

Sounds like you have dirt in your float bowl or your float needle and seat are worn out. Pull off the float bowl and look for contamination, remove the float and see if it is full of gas (it should NOT be) and check the float needle to see if it is grooved, cracked or badly worn. Be sure you change your oil as it has gas in it!!!

SOURCE: I have a 7 year

I have a Craftsman mower. Last year I had a similar problem with the mower stopping after running awhile. I noticed that the plastic gas tank was collapsing. The next time it began to stall, I immediately loosened the gas cap and it didn't stall. The vent holes in the cap had plugged up. Check this out.
I can't help you locate the fuel leak, although it sounds like the carburetor float is not stopping gas from flowing into the carburetor.

First you need resolve the carburetor issue. With it leaking fuel it can flooding the engine causing it to smoke. The leaking can dilute the engine oil by overfilling the crankcase causing smoking and other damage, Once carburetor issue is resolve and it still smokes the initial 10 minute start-up after the rebuild then a compression and leak down will need to done to determine if you have blown head gasket, bad rings, or other problems.

Oil will be drawn into the engine under heavy acceleration, irrespective of load. Check this before you worry! You might also check for any external leaks of oil or hydraulic fluids around the exhaust area which could cause white smoke at odd intervals.
Good luck

2003 lincoln aviator/how do you know if there's motor damage


Your car shouldn't have just suddenly started burning oil. Its possible it's leaking in the engine compartment and the leak is dripping onto the hot exhaust manifold and the. The smoke is blowing out the back as you drive. I would think it's unlikely that the engine has been damaged since the check-engine light should have come on if the oil level was low enough to cause damage.

If hii find that bluish smoke is coming from the exhaust pipes, then the next thing to check is whether it smokes on acceleration or deceleration. If the latter, it may be just a valve issue. If it smokes a lot on startup, then it may be rings.

Using oil...no leakage...no smoking


by recently, do you mean, since it got hot outside? if you're using a multi-vis oil, it gets too thin in hot weather and will "vaporize" and burn, not enough to cause smoking. use a good 30 weight oil. other than that, can't think of anything else that would cause it with no leaking or smoking

Oil leaking from air filter area of push mower and mower smoking


You have overfilled the oil tank. White smoke is only a hassle, not a serious problem. You have to empty some of the oil and change the gas. Clean the air filter if it is the spongy type with Dawn Dishwashing Liquid, rinsing and drying it well before reinstalling. The white smoke will stop soon as it is still in the gas that is in the carb. If the case is that you haven't filled it with oil prior to this smoke then you must be mowing on a hillside and the gas tank was on the lower side allowing oil to leak into the gas. Same solution.

Audi engine oil leak?


Sounds like a leaking valve cover gasket. The parts are around $50 to do both cylinder heads from www.ecstuning.com. It's not a major issue, but it may be a sore point to a potential buyer.
