6600 blow-by

[zh4020]

6600 combine with rebuilt 404 - no turbo. Ran fine last year. This year has a lot of blow-by. Uses 3 quarts in a day. Only 60 hrs on rebuild. Any ideas what is going on. No oil or smoke out of exhaust. All out of the blow-by tube. Thanks for any help.

Was it O/H'd with Deere piston liner kits ? it sounds like you have a broken ring or 2 Darn it..
