It depends how much is to much, if its about one half a quart there should be no problem most cases even up to a full quart too much wont cause harm. But if you have a quart or more too much i would sudjest locating the drain plug on the bottom of the oil pan and draining some. Worst case senerio you could blow the seals front or rear main, or simply cause a gasket to leak.
Draining the excess will solve the problem.
It will float.
If your husband poured barsleak in the crankcase, it probably stopped up the oil pickup screen. It is supposed to be poured in the radiator. The engine is probably ruined if you have driven it with the oil light on.
u will blow your engine oil seals, causing an oil leak and damage to the engine.
The oil floats to the top.
too much oil in the engine will cause of airation and will create too much pressure to your engine and will damage the headgasket.
You need to change the oil before driving the car. The Wiper fluid will dilute the oil causing it to foam up and not lubricate the engine.
It can cause engine damage.
when the engine is run the oil and water will make a thick pudding like mixture that will not lubricate the engine, you will need to change the oil and filter again. ( this mixture can clog the filter ) You may also need to do an engine cleaning procedure as well, that mixture will stick to everything and be there after several oil changes.
putting too much oil in any engine is not good... the oil can over flow to your spark plug... that can cause stall..
not much. it would change the viscosity of the oil. the diesel oil is much thicker than regular engine oil.
when you put too much oil: engine will lose much power oil push out and make damage your catalic converter
