Excessive blow by?

bigastrk · Feb 23, 2013

I am wondering if this is excessive? I don't have a video but I found one on youtube that has just a bit more than mine. Here is the link. What do you guys think? Is this to much or does it look ok? I only have 60k on the truck but its an f450 with 4.30's I have a feeling the high rpm's are starting to get to it. I usually only run 65 but that is still 2300-2500 rpm's.

its really hard to tell by a video.

Basic rule of thumb, if it blows the cap off once you unscrew it and just let it sit on top, its usually on the high side for blowby.
