How much blow by is normal?

[Ericshere03]

question, how much blowby is normal for a diesel? I took a video of how much I am seeing on a totally warm engine with 2500 miles. If I saw this with a gas motor, I’d flip. I don’t see any chugging, just a smooth stream of oil vapor. It’s consistent and steady, no chugging as if a single cylinder has excessive blowby.

I cannot say what is normal, but rest the fill cap on it and see if it dances around as a better indicator of blowby. That could just be normal vapor.

Did that, there wasn’t enough pressure to blow it off or anything … so that’s good ?
