oil cap pressure

[ibiza owner]

I had my engine idle running on the drive the other day and just decided to remove the oil filler cap on top of the engine whilst the engine was idling and there was this tremendous sucking of the cap (like a vacuum) as I was pulling the cap off and I was quite surprised at this.

Should the engine be sucking like this wen I am trying to remove the filler cap or could there be something wrong with the breather system on the engine.

I have never noticed this on any of my other cars, when I have removed the oil filler cap on my other cars there has never been a vacuum pressure like this.

Does it happen on your Ibiza?

Cheers,

Andy.

Bit dangerous doing that,mate. the oil is presurised in there.

Thanks, but why dangerous?

So it is working right then, it should be pressurised like that then is that right?
