2015 tdi crankcase pressure

[fpchief]

Hi, I am not really finding an answer to what I am looking for. I have had a 2013, 2009, and have an older Jetta tdi. I am looking at a 2015 with 87k miles. It is a gem. I took cap off and there is ample pressure coming out of the crankcase. I have not seen that in my others. I have had many Cummins diesels and I would 100% call this blowbye. But on these, I am beginning to think it is almost or is normal. It is much more than just oozing vapor. Can someone give me some insight on this?

Thank you in advance.

some pressure out an open oil fill cap is normal for proper PCV system to work.

Can't say how much is too much though.

Any leaking around the oil fill cap?

Mine may be a little more than this, but not much more and I am at 402k miles..
