Too much oil in engine, white smoke?
I excessively overfilled my engine with oil (more than 5 quarts) in my 2001 Honda Civic EX. I drained the excess oil out after the car would not allow me to acclerate. After draining the excess oil and refilling it to its correct levels, smoke keeps coming out from the exhaust when the car is idle and when I drive it around the block for several minutes. The smoke is rather light in color (almost white or light grey). What could possibly be wrong with my car and how should I go about this?
I had the same problem
Rev the engine at idle for 10 seconds, back off for 10 secs until the smoke clears.
Water is white smoke.oil is always blue
Take it for a blast up freeway one exit and back
A long trip should clear out any residual oil which is what it is.
Clean the throttle body and MAF sensor with brake cleaner and blow dry them. Then again if you can't even change your oil with out Fing things up you might want to let a mechanic do it for you!
Since you know you overfilled the oil and the smoke is something you've only noticed since then, it's almost certainly oil smoke you're seeing. It will burn off over time.
If you think the smoke is due to coolant (which I doubt), check your coolant reservoir level every day for a week or so. If the level remains constant you don't have a leak and the smoke isn't a result of coolant.
The PCV and/or breather hose may have oil in them. I recommend removing them (and the PCV valve), cleaning them up with carb cleaner or similar, and reinstalling. Give it a day or so for the residual oil to work it's way out of the throttle body, too.
Oil has worked its way into the combustion system and out through the exhaust.Too much oil will cause excess pressure by the oil pump and crankcase and therefore placing strain on the seal on the rear main bearing. If the pressure is not relieved the seal will rupture and it will increase the oil that leaks out.Once the oil begins to leak out from the ruptured seal, the oil passes into the clutch and causes more damage to the vehicle. If the problem still is not corrected the front seal bursts and causes the engine to gush oil.Overfilling the oil also causes the rotating crank to churn the excess oil into a froth. The aerated oil is pushed into the bearings and afterwards into the pistons where the piston rings will begin to break down from trying to overcome the excess oil and pressure. If the oil has worked its way into the exhaust you may have caused irreversible damage to the engine.
You gave got oil into all sorts of places.
Take it for a fast 100 mile run then see him it is.
- Spark plugs covered with oil plus exhaust smoke? Just got the carbs cleaned and working perfectly on my 82 Honda Nighthawk 450. I started the bike and just a moment later there's a white smoke coming from the engine and exhaust. I took the spark plugs off to aid in addressing the issue and I have found that there's a black oil on them. Anybody have an idea as to what's going on here?
- Mechanic said he rebuilt the engine, smoke coming out of engine, could it be the grease burning off? The mechanic said he rebuilt the engine to my 1974 Honda CB550 I bought from him. Said he rebuilt the engine and is in perfect running condition. He has many bikes lying around and seems as if he is a hobbyist for bikes. He told me that he basically greased up a lot of parts of the motor and it is burning the grease off. The next oil change I do should remove the excess grease.
- I replaced my engine in my car and white smoke comes out? I have a1997 honda civic ex and I had to replace the engine and it's blowing out white smoke from the exhaust
- Oil Change: Honda Motor Oil Vs Generic oil, does it make a difference? I have been getting oil changes with Honda motor oil for 15 years on my 2002 civic that now has 132K miles. If I switch to a generic $10 oil change garage shop will it still be ok? I know the Honda filters are better then the cheapest generic ones but how about the actual motor oil?
