A new crankshaft oil seal may blow due to improper installation, such as misalignment or over-tightening, which can lead to excessive stress on the seal. Additionally, high engine pressure from issues like a clogged PCV system or excessive blow-by can cause the seal to fail. Using the wrong type of seal or incompatible oils can also contribute to premature failure. Lastly, engine overheating can deteriorate the seal material, resulting in leaks.
You won't necessarily blow any seal. You will however destroy the engine if you overfill it enough as to allow the crankshaft to make contact with the oil. This will create a froth of oil mixed with air. And as you probably can guess air is a very poor lubricant. This mixture will cause engine wear and overheating.
how do i replace a front crankshaft seal on a 99 mitsubishi mirage

Need to know what seal you are talking about. Front crankshaft seal, wheel seal, etc?
Yes and No. Blow by is caused by an inproper seal between the compresion ring's and cylinder's. And yes a broken choke pin can result in flooding the cylinder's with fuel which will result in scoring of the cylinder's and a poor seal. Did this help?
