noise on removal of oil filler cap LZ

[puta 1]

Hi,
I have a LZ Focus 2015, i was wondering if it was normal when you remove the oil cap to hear a lot of banging coming from the engine when running. I know i shouldn't remove it when the engine is running

Thanks for any info in advance.

If you know you shouldn't remove the oil cap when the engine is running.
Why did you do it?

stupid is as stupid does
It's all good, checked with a local mechanic turns out it was nothing.
