quick questions

-how many bolts secure the passenger motor mount bracket to the engine block?

-do I need to remove the motor mount also to remove the dpf?

-do the O2 sensors need to come off before removal?

There are 4 bolts holding it to the engine. One of these is through the middle of the thicker part down in a hole.

I did remove the mount as well. More room is better pulling the DPF. There is a bolt holding the mount against the body from inside the fender well side.

I didn't remove the sensors until it was out

Here is what the promised land looks like

Not saying other guy is wrong here. I preferred to take loose all sensors from DPF body. I didn't want a spaghetti of wires moving with DPF when it came out. Otherwise the opposite end of harnesses that are part of sensors has to be disconnected. I'm not real good at not damaging the connectors so I minimize messing with them. The only issue this brings about is when replacing the front EGT. You have to "back spin" it to where you don't get a bunch of twists in cable after spinning it to tighten. Don't get the EGT mixed up when replacing. I have done the other mount both ways. Last time, I only removed top nut to disconnect bracket from mount. This was when I was pulling aftermarket down pipe though so I didn't need as much room. Pull the mount if you want. Good luck.

The front sensor is O2 and back is a NOx

thanks for you guys giving me inputs.

You have to go "through" the motor mount to get to 1 of the 4 bolts. The rest are easily accessible.

I pulled the sensors I needed to keep for the downpipe and left the rest in there and it dropped no problem.

Mount definitely needs to be spun out of the way. I didnt pull it all the way out but I did spin it away.

The through the mount bolt was easy for me from above, a small extension on a 3/8 ratchet got it not problem, at least until I got the mount back on and my buddy put a second bolt in that hole. It proved to be extremely difficult to tighten one bolt onto the head of the other . It was one of the other bolts that gave me trouble.

where do I disconnect the nox sensor, end of the covered harness or the black box next to the trans?

[BB_cuda]

The box next to the trans. It's on a bracket right by the fuel filter.

gotcha just remove the box or just unplug the otherside.

[BB_cuda]

unplug other side. I went a different route. I got an M20 bolt from store. I think it was an M20X1.5 but I need to double check the pitch so don't quote me (yet). I removed the NOx sensor and all of the orange cable connected to it all the way through the box on the other end. I then plugged the hole with stated bolt above. I wrote in another thread so I will go look for it. There is a section in auto parts store called help. They had an assortment of large bolts M18, M20, and washers to go with it. The M20 was the right pitch and I corked the NOx hole in my down pipe.

I only got to bungs up top on my down pipe...

[BB_cuda]

That sounds like the very front EGT and the Ox sensor.

[32valves]

this the two I need for the down pipe right?

and what should I be doing with those two 7mm hoses just let them hang or plug up with bolts, or connect the together?

[BB_cuda]

You need to talk to your tuner to make sure that he uses the front most EGT and Ox sensor. I'm betting this is the case. I know these are the bungs on Bohldiesel's pipe. Not sure which pipe you're using though.

I left the two black hoses just hanging there and nothing plugged to them. A couple guys have found good experimental things to measure differential pressure on using those hoses. Example: TDI measured back pressure on the SCR as it was starting to clog up after DPF removal. You don't have to do anything with the hoses though. You do need to have a plan for either gutting the SCR or removing it though. You likely know this hopefully. How about some pictures of your DP install. Good luck wrenching.

I have a bpc pipe.
I will take some pics too.
