CCV Delete?

[Cummins20126.7]

Can you delete the CCV before you tune? Or tune first?

It didn't throw any codes on my 12. But I think I heard that it did on 13+. I don't think it would throw the truck into limp mode but you'd get a cel

Same in my 2012 but like you said, ‘13+ May be different!

After reading this thread, I checked my crankcase pressure on my MM3 and when I am on the throttle it jumps to around 37 psi, when light throttle, idle or maintaining speed it is around 0 psi. Does anyone know what the stock pressure is or if this is normal. 37 PSI seems pretty high. I read through the service manual and it does not give normal pressure ranges (If anyone is interested, I can post the service manual information)

Mine does the same thing. Seems normal to me!

My 17 is deleted, but haven’t removed any of the EGR stuff quite yet and when I pulled up the pressure on the MM3, it was at either 0 or 37... seemed to jump to 37 around 1800ish RPMs.

That rubber cover is what I'm trying to find, but don't know what to call it.

There's almost no chance you've done any damage. I've read that if your filter is clean and changed regularly it doesn't matter. But once there's some oil saturation in the filter, the vacuum is needed. I'm gutting mine because vent to atmosphere worked fine for a lot of years and that filter is just an afterthought to appease the EPA/emissions nonsense.

I made things easy on myself and just bought a boat plug at Ace. You can get the same thing at Walmart

Just turn it a few times to tighten it up then push the little handle over to lock it down

That's clever. Didn't even think of that. Should have updated, but I did order 3/4 heater hose cap. Thanks though!

For less than $1 can't complain

I deleted my CCV filter this afternoon. Gutting the filter was definitely not easy, but maybe mine was just baked on. Filter media was completely soaked with oil so I'm betting I was close to changing anyway with 66k miles. I vented it to a hole in the frame just behind the passenger side spring. If oil drips in there it has a drain hole back by the transmission cross member and I don't smell it. Anybody see an issue with that? My cc pressure is noticibly lower, idling around 0-0.03 where is was around 0.15.

I'm curious what I would call the piece that plugs the barb off my S&B intake? I could make something up, but the piece in that kit looks pretty slick. Noticed lots of oil in the tube when I deleted my EGR, so I'm going to be gutting the CCV filter soon.

I will be doing mine soon as well I think I will be looking at these various sizes not sure what size is needed 1/2 inch or 3/4 but they have many sizes
