A clogged PCV system will cause a buildup of pressure. Much worse when the engine is old and worn with lots of blow-by. ---

The crankcase vent has become a popular topic lately. ---

Someone neglected to install the oil cap after adding oil and the guilty party is telling you that it must have just blown off. ---

I’ve seen it happen. I was driving a 4 cylinder Ford Fairmont, a company car, and it broke down and the oil cap blew off. ---

One would think that the oil dip stick would blow out before the oil cap? Tester ---

I’ve seen more dipsticks blown out compared to oil caps myself. Most caps these days twist and lock don’t they? ---

A faulty PCV valve (cheap) or the engine has a lot of blowby due to being worn out. (expensive) If the oil cap; was tight it should not blow off and in most cases the oil dipstick will get blown out of the tube first. ---

> [@Rod\_Knox](#): > > I’ve seen more dipsticks blown out compared to oil caps myself. Most caps these days twist and lock don’t they? +1 Yes, that has been my experience for several decades. However, the OP’s question had to do with an oil **field** cap, rather than an oil fill cap, so perhaps this issue is best left to the companies that perform oil field exploration. 🤔 ---
