Dave-
What you said about the blowby makes sense, and I'll pop off the filler cap and have a good listen next time I start her up. The engine seems to run pretty strong, so I'll be really surprised if I hear any huffing and puffing. Although my engine has only 40K miles on it, I'm sure the seals are probably in need or replacement. Plus it should make for a fun evening or two out in the garage.
I have small kids and I have a hard time blocking out time to work on the truck, but this seal business is something I should be able to do without asking my wife to watch the kids for too long..
Thanks!
