no not at all... the issue isn't the bearing , the issue is the dirt passing thru the bearing into the engine.....
The vacuum port theory is easy to test....just do a brake cleaner test at the nose of the engine when its running..a engine will a open vacuum port will stalll instantly when it sees nitro spray...However a engine with the vacuum port blocked will nearly be unaffected by nitro spray.....it makes a big difference.......

So what you are saying is that all engines with open vacuum port, in theory should all be done in about 2 gallons of fuel? Based on your theory there is no way they can last more than that under dusty conditions.I think the bearing will die early, like I said before,I dont think that much dirt can go thru the engine to make it fail early.Are you saying that all that dirt goes in through the open vacuum port or the front of the crank.If that was the case the oil and dirt would've plugged that hole very fast.If it was the front of the crank,you would see scratched marks on the front part of the crank like you see in a crank window when a filter fails.
