It will work for only so long, and the result would be even worse, IMHO.
Here is what will happen: If the N62 engine will start smoking, and you fix the problem soon enough, you probably cured it. For good.
If you leave it like that, you might induce another problem. Look at the pic below, where you have the O.E seal with a few months, very little mileage smoking issue, and Elring Klinger seals. The difference is self explanatory
The opening where the valve stem travels is growing bigger and bigger. The next thing will happen, is the valve stem will rub against the guide, and will wear it down. There are quite a few N62 long time smoking engines, where the owner finally decided to fix the problem, and once the engine was taken apart, this issue was obvious. So what happens next, is you need to change the valve stem guides, and pray that the rocker arms are not affected by this. Tolerances are very tiny here.
