Yes, too much engine oil can cause blow-by. When the oil level exceeds the recommended amount, it can create excessive pressure in the crankcase, forcing oil past the piston rings and into the combustion chamber. This can lead to increased oil consumption, reduced engine efficiency, and potential damage to engine components. Maintaining the correct oil level is essential for optimal engine performance.

Can to much oil cause vehicle to blow white smoke out the tailpipe?

Yes, too much oil in a vehicle can cause white smoke to blow out of the tailpipe. When the oil level is excessively high, it can lead to oil being forced into the combustion chamber, where it burns along with the fuel. This improper combustion results in white smoke, which indicates that oil is being consumed in the engine. It's important to maintain the correct oil level to prevent engine damage and ensure optimal performance.

Will too much oil in your car cause it to throw a rod?

Too much oil in your car will not cause it to throw a rod. Too much oil in the engine will create a higher than normal engine pressure and can cause the engine seals to fail.
