Time to Inframe?

[Rawze]

(just my own thoughts) its time to inframe when...

* (no dpf in exhaust) - oil consumption is more than 1 gallon every 3000 miles or so, and it is established as excess blo-by.

* (with dpf in exhaust) - oil consumption is more than 1 gallon every 8000 miles or so, and it is established as excess blo-by. The DPf can no longer keep up at this point.

* rod and main bearings were not done at 800k miles, and it has more than 1.1 million on the enigne.

* If the head has to come off for any reason (worn out head, dropped liner, head gasket, spun cam bearing, etc.) and the engine has more than 450k miles on it... Its time to inframe it.
