2011 and 2012 motor differences

[steeldiesel]

Were there any motor changes to the 6.7 from 2011 to 2012 model year??

I know they changed the oil pan to metal!

Yes mine is metal, also the fuel canister on top of the engine is a twist on and off, no tools need it, no side screw, that's as far as I know what's different

Thanks guys

Hey dlsbrnr. Do you like your 3.31's ?

[dslbrnr]

Yeah steeldiesel, I was hesitant when I got the 3.31's but since I won't be lifting ect it's great. I see 20 MPG on the Hwy and with 800 Ft Lbs of torque at 1600 RPM 331's are fine. The tow rating is the same with 3.55 vs 3.31's. At 70 MPH I'm tacking about 1600 RPM.
If I was lifting I would have chosen the 3.55's though.

My build date was 06/12 and the fuel filter under the hood is the plastic one, no twist off!

Actually it looks like it won't , but in Oder to pull it out you have to twist towards the cab and then pull up, to replace repeat the same steps, I have the same built on my 12 and I just replace both filters, the filter has two nobs one on the side and the other in the bottom of the filter, both nobs have to be align to lock in place.

And I was taking about the oil pan been metal not plastic, the 2011 have a plastic pan with a yellow 1/4 turn plastic plug

[dslbrnr]

Oh ok, gotcha! So no screw or bolt to attach, just twist and pull out. I wonder if the older style filter will work.
