Where to hook up smoke machine?

[BlackBart]

On mine I removed some things for room and did a lot of cleaning back there, then replaced all those hoses with the bright-colored silicone set from ipd. Easier to keep track of the routing, and so much easier to see than black.

To replace the CBV, I just removed the airbox top and snorkel tube. That gives plenty of room to see and work on the turbo. Maybe the heat shield. Only three or four bolts for that. The CBV can be installed in place, but I found it helpful to install the vacuum hose first, and then hold on to that hose to hang and move the CBV around while you use your other hand to thread in the three bolts.

Just placed an order for the IPD CBV kit (#124917) and the silicone multicolor hose kit (#122041). My turbocharger is original, has never been off the car, and the CBV may be fine, but the diaphragm and spring are getting old, so while I'm in there it's getting replaced.

Back at it again today, got the heat shield off and the turbo air inlet tube (snorkel) out, now much easier to see things, but first I need to clean the grime away. I'd like to clean that area of the turbo, thinking of using carb cleaner. Also the snorkel can use a good cleaning, I plan to seal it up while it's off the car and smoke or vacuum test it. I'm looking for a safe way to clean the snorkel, would it be safe to use carb cleaner. Also, I see the PTC is installed in the tube, and from what I've read there is a periodic cleaning advisory, but I've never cleaned it. Can't find a write up on cleaning the PTC, would carb cleaner be okay for that too?

Carb cleaner fine. Just dampen paper towels and wipe. Nitrile gloves for your hands. It doesn’t have to be surgically clean

The PTC nipplevalve is just a hole heated by electricity. Clean off the grunge and make it shiny. It’s a 50k service item.

Today, I removed the air/turbo inlet tube, aka: "snorkel" (#9186200), cleaned it with carb cleaner, and noticed the lip that fastens at the turbo was very thin with a slight deformity which was made by the hose clamp over the years. However, the deformity did not look like it would cause a leak. I sealed the snorkel with rubber gloves at each end, taped the nipples closed, and introduced smoke through the PTC. The leak was readily apparent where I noted the deformity. I tried to use a hose clamp on the rubber glove, but it still leaked. I think this was the source of the P0455.

I thought it would be an easy fix to simply replace it, called around and found it's no longer available, now out of production. I called a Volvo-Saab dismantler that I frequently use, but they're closed today. Due to time issues, I decided to order a new silicone part from IPDUSA, $286.99 plus tax, which will be delivered next week.

Once I put everything back together, under the hood, I'm thinking of smoke testing at the charcoal canister to see if the lines that go back to the gas tank, including the tank and filler neck are leak free. I don't think the smoke test I did in the engine compartment tested that part of the system.

Glad you found the source of the leak. Yea, those plastic snorkels do deform/crack over time. I installed one of those IPD silicone turbo inlet hoses last year. Do make sure it's clamped on tight to the turbo, or else it will come off over time, and cause your call to stall. Ask me how I know. : )

Shout out to abscate, who said I had a loose induction hose creating the stall in this thread: viewtopic.php?t=101157

I just tightened it up, smoke tested, and now no leaks. The hose looks a little weird clamped on the turbo, because the hose is a bit wider than my stock turbo. So the hose kind of "bows out" between the clamp and the turbo.

I'll be curious to see how yours works out. Post some photos if you can.

Hopefully it stays on now.

One more tip, now that I think of it. I had a bit of a time getting the IPD hose around my MAF. A heat gun softened it up nicely, so as to help me get the hose on.

Also, you'll have to dremel off part of your PTC to fit it into the IPD hose, but you perhaps already knew that.

Ouch....

What brand is your smoke machine? Seems way more usable than burning rags.

99 TurboBrick, I ordered the black silicone tube, they did not have the blue in stock which would take two weeks to get, and I need to get the car back on the road as soon as possible. I have a smog check coming up in January and need to get rid of the P0455.

I didn't know about using a Dremel on the PTC, IPD told me there is a video on installation, and that I would need to cut the Volvo grommet to remove the PTC from the old tube, the grommet is not needed on the new tube. Thank you for the tips on securing the hose and the fitting the PTC.
