dipstick coming out

The cause of the spring popping out is crankcase pressure. The rubber seal on the dipstick over time gets smaller and more brittle from the heat of the engine. When this happens it pops out easier and easier. Compounding the problem is the ring seal getting worse with mileage and generally higher boost pressures.
The spring fixes it, obviously we don't get rich selling them and CBRD doesn't get rich from o-rings.
The spring we make, should not fall off though as was said earlier. It is bent in such a way that when you put it on the dipstick bracket it should not fall off. I also can't understand having to use a set of pliers on it, it's not a brake spring and isn't really that stiff. Maybe my hands have just toughened from punching walls and my desk over the years! haha
Anyway, either will work but there's why it happens.

come on dave, you know im funding my time attack car with o-ring sales LOL!!
I know your spring money goes directly into the black car lol

Amazingly enough, you can make a very good knockoff of the Buschur spring kit at Home Depot, Lowes, or your local hardware store. But shhhhh...... don't tell anyone

I don't understand how boost can cause this on a normally operating engine. Normal, I mean the following isn't happening:
Shouldn't sump pressure stay the same regardless of boost?
- Pvc check valve sticking open
- blocked MAF pipe outlet on rocker cover
- blowby

I could be wrong, but I want to say these are the reasons this can happen while nothing inherently is wrong:
a) more boost and more power = more cylinder pressure
b) longer stroke engines might disturb the crankcase more
c) forged engines made with looser tolerances than stock motors
d) o-ring on dipstick becomes loose over the years
Now I'm quite unsure about point A. In a perfectly setup stock motor... is there ANY blowby across the rings? I'd have to think there is _some_.
