New 6.7 owner...

Posted

Ok guys...Here goes my first post. I have been a viewer for several years and greatly appreciate all of you that have shared your knowledge here. I just purchased the 2010 for my wife to drive and I have a question regarding the 2 cycle oil diet. I use it religously in my 2001 after replacing three VP44's and 2 lift pumps (I know, I am a little slow catching on ). But with all of the emissions stuff, I am unsure if it will help or hurt. We just retired and moved to Wyoming in November and are loving it. Just need to keep these two "children" happy and fed well. Thanks in advance...

Actually with the Emission junk on you can't run the 2 cycle oil because of the DPF and EGR problems... But if you mod it later in life and yank that stuff out I know of a small handful of guy using 2 cycle in 6.7L that are moded... But the biggest problem is the filter... You need to add a 2 micron filter... The electronic injector are a weird duck but the fact is there is a very small BB that seats in the head of the to control the injector firing well the debris will hone the seat out where the BB seats and then it bleeds pressure causing the injector to bleed constantly... Hence hard starting and whit smoke issues.

Thanks for the response... So any recommendations for the filter? I use Fleetguard filters in my FASS pump on my '01...I will scour their catalog.

I hear unplugging the EGR is very important on the 6.7? I have owned a few EGR diesels, and to stop the gunk, you got to disable the EGR. Just wondering, are the feeding the CCV into the intake on these 6.7 engines as well, or do they still have the draft tube?
