How much blown by is too much. I have some coming out the oil dipstick tube. I was on the road, and decided to check it, while engine running, and there was smoke coming out of it as soon as I took the dip stick out. So I unscrewed the oil filler cap, and there was a lot more from there. I know some amount is ok, but the amount of smoke from both places has me concerned.

How do you measure how much is too much? How do you measure it?

 

Unscrew your oil cap and then just set it over the hole with motor running. If it blows it off the hole its too much blowby. My has a bit of smoke out the whole but doesn't blow the cap off.

How many miles on the truck?

 

It's currently at 95000

 

How much oil do you have to add between oil changes?

 

Added new video of cap on fill hole, unscrewed

No oil added between oil changes. Most of time if a tiny bit higher than the max line
