Living with the duramax vs the 6.0L?

The LB7 is a good simple (relatively speaking) design with the least amount of emissions BS. The injectors are the only real problem they have but at this point I’d think it’s safe to say that 90% or more of them left on the road have had the injectors done- that was a not if but when they fail problem. I’ve done them personally on a few LB7’s now and generally if you put good injectors back in them you won’t have any more issues for a long, long time. Bosch has upgraded and refined these injectors a few times and they are a lot better than they were 15+ years ago. At least that is my experience. The big downside to the L5P is all the expensive, trouble prone, emissions junk on it, it can be deleted but that is a whole other topic depending on where you live, emissions testing etc.

Could the emissions be "capped off" until it was time for the test? Then once you get your sticker, you simply undo the emissions connections again. Would it be easy enough to do this on the L5P?

And if you did, would you need to make any extra arrangements to protect certain things, since all the soot will now just flow into the exhaust system?

For L5P deletes, sure, I guess you can do and undo every year for emissions but that’s crazy talk. Nothing is cutout for deletes, but rather removed, so it’s doable. I would be concerned with your mental health if you did this

I will just say that I have “placed” but not hooked up emissions equipment to give the appearance everything is good to go. But when 2007+ duramaxes rolled out, “placing” things in its place becomes more difficult because of the amount of equipment you’re removing.

There are ways of doing deletes and dealing with emissions, but for obvious reasons, I won’t elaborate on them in a public forum.
