PTC Nipple removal and cleaning

[swimNdrive]

I have done a search on PTC Nipple. Apparently this is not a separate part. If I damage it while pulling it off, I will have to replace the whole pipe at about $100. Does anyone know who sells it as a separate part?

On the same topic, I saw a youtube video about Snabb's Intake pipe. Does anyone here have it installed on your car? How do you like it? Besides of the look, does it actually make any other positive difference?

I am thinking about taking the whole hose out and clean the PTC nipple. This video does show a good way of separating the intake hose and the intake filter box. But I was not able to see how the other end was taken apart from the turbo, nor I could see how it was installed back on the turbo. From the top of the engine, I am having difficulty to see how the hose was connected in my XC70. Will that be easier if I take them apart and re-attach them from the bottom of the car?

That's something you'd get from a junkyard or as a used part.

Just twist and pull at an angle and it'll pop right out of the pipe with no damage.

I removed the whole pipe to take the thing out, and I would strongly suggest doing that as it's harder to get the PTC nipple shoved back into the larger pipe than it is to get the intake pipe back into the car. There's a pain in the butt hard-to-see clamp on the hose there. Get a bright flashlight and hold it in your mouth, or get a helper with a huge light to focus it down in the area so you can see.

Lay or sit across the top of the engine to get to it.

Thanks for the reply and info. I was able to get the fresh air pipe of the turbo. However, I am not sure how to disconnect the PTC heater cable connector, too afraid of damaging it. The connector is locked by a metal wire lock. Do I suppose to pull it out or move it to one side, which side? It is tied and very hard to move it around down there.

I have been searching this on the net but could not find any information specific to this connector. It seems to me it must be an easy thing so people did not even think it is worth it to mention it. But I am stuck with this thing right now. If there are some pictures will be very helpful.

I have been taking pictures as I go. I will post some of them that I think it may help others here once I am done with the job.

Well, I was able to remove the wire lock by force. Did not damage it, but afterwards, I learned this lock should be move up or move to the right to unlock the connector. Either way it was difficult because there is no much room to work with down in there.

After I took out the fresh air pip, while removing the nipple, I broke the robber grommet. The rubber grommet was too brittle. Lack of comparison with a new one, still I think this is due to its age. This rubber grommet seems an integral part of nipple for my car. I could not separate them. For the time being, I think I am going to just find way to hard glue it.

By the way, I found the part number for the nipple, it!s on the nipple. It is 9445831, some place online sells it for about $59. Next time I have a chance to work on this part, I will try to order and replace it then.

Now I need to clean it up, put it back and glue the rubber grommet, then install the new PCV system.

Bummer. I wonder if mine had been replaced at some point perhaps when a PCV system had been done before (not sure that it ever was, judging by the condition of the hoses)...but it was still pretty pliable.

The job is done! It took tons of patience and as well as lots of strength. I was very tired at the end.

I have done PCV and PTC all together on my 2001 XC70. It was a biggest job I have ever done on cars. The car was leaking oil and all other signs that indicating the problem was PCV and PTC related. After the job, I took the car for a ride, the engine was a lot more responsive and the strange sound from the engine went away along with the check engine light. I am very please with the end results. I would like thank all the people who have posted their work and thoughts on this forum, which enable me to do this job myself.

I ran into a lot of difficulties while doing this job. I was unable to see how the turbo was connected to the fresh air pipe. I ended up laid over the engine and extended my arms as far as I could to reach the bad boy down below and located the claim head screw. I had to feel it! I used a 7mm socket to loosed it. I waggled the fresh air pipe very hard to disconnect the pipe. I was also unable to disconnect the heater connector due the space and did not know how to unlock the wire lock. I ended up pulling the wire lock very hard to get it out. While reconnecting the heater connector, I just left out the wire lock. I think the connector is secure enough without it. While separating the nipple from the pipe, the rubber grommet was damaged. It is very hard and brittle due to age. Since I am not planning to take it out again. I just supper glued it. It worked. Next time if I need to do PTC again. I will buy a new pipe which comes with the new nipple.

Here are some PTC related pictures I took while doing this job. I am convinced if the PTC is leaking, PCV job is due and vise verse. I replaced everything for PCV. Now I wish I bought a new fresh air pipe so it would save me some time and effort, and I won't need to replace it again in the future. I will share my PCV experience and thoughts on PCV related threads.

There is drop of fluid under the turbo.
After spending an hour or so looking, I was certain it was not from the two coolant lines.

My next suspect was PTC. Familiar site swimNdrive!
I took off the torque rod above the engine, then, with a flashlight and moving hoses, I found the trail at the nipple. It is a vapor leak, no major buildup on surface, not yet.
Could I go like this for few months?

a leak at turbo...

Yes. You might see a P0422 if it burns during driving and sets off this front O2 sensor code.

It takes off little pressure this graduation season.

Dr. Matt.
The CEL checkup at Advance Auto Parts today is indeed P0422. What'd ya know.
Can't wait to go to a steelership and get ripped off.
