BLOWBY!? :rod: :banging: Someone please make me feel better.

AAAARRRGGGG UGGGGHHHH mmmmmmffffffffff

ANYONE EXPERIENCING BLOWBY?!?!?! Did an EGR Delete, and boom, blowby. Never had it before. Not excessive, doesn't blow off cap...I've researched and according to everyone on here and other diesel sites, I'm OK...but it still makes me paranoid as fffffffffffffffff...

SOMEONE TELL ME HOW THIS IS COMPLETELY "NORMAL" WHEN NOT ALL OF OUR 6.4'S AND OTHER DIESELS DO IT?!? My 6.0 NEVER did this. Is it my synthetic oil, bad orings, pistons, what???

Just so you don't think I'm a moron, I've done my research and have read everything I can read. I'm still not convinced. And it doesn't help I'm an engineer so I'm naturally paranoid!!!

Mine does it when it's warm, also told it was normal. That was 15k miles ago and my truck still runs just fine.

I was just like you and I was told that it does it bc the engines were built so that when it gets heated up to running temps while driving(under load) that parts expand and seal like they are suppose to.

Don't know if that is exactly correct but I believe its close.

And I also didn't notice mine till after my egr delete.

Thanks for the reassurance fellas.

Y&R0864--how many miles on your rig since you noticed? Do you think it's coincidence that we noticed after EGR delete? I mean i hate to sound ignorant but that just doesn't make sense...and to see so many fellas with the same thing. How often do guys check their oil while the motor is running? My neighbor has an 08. I'm about to walk over to his truck while he's sleeping and start it up to see if he's got some blowby to ease my mind. haha

All diesels will do it. Mine has done it sense day one and it now has 40k on it. I vented mine so that is dosent fill the intercooler with oil, and it has a good amount of blowby. The reasone you don't see it normally is because its plumbed into the intake for the turbos.

thanks for the reassuring note brother.

do you burn oil? notice any oil loss between oil changes?

I read on another site that the crank case actually needs the vacuum from the turbo/CAI to help the motor's CCV efficiency? is this incorrect?
