Help Installing do88 Intake Hose!


NWBen

Recommended Posts

I am in the process of installing the do88 silicone intake hose but I am totally stuck. There is a sensor that looks like it connects the PCV system to the intake hose. The sensor seems to have a flanged plastic piece on both the inside and the outside of the hose holding it in place, and I have no idea how to remove it from the old intake hose.

If anyone can let me know the trick to removing the sensor from the old hose, I would greatly appreciate it.

The PTC valve on the intake hose is just sorta held in by rubbe?r, you can firmly pull it out or butcher the existing hose. I had to grind down the edges of the ptc to fit into the do88 intake hose (it will still be plenty snug, it just has a lip that makes it near impossible to get into the hole)

As for the line/hose connecting to the PTC, handle it with care if you are intending on removing it. It is a bugger and has different sized ends if you were to botch it, making finding a quick replacement difficult possibly.

Sorry it took so long to get to this. I did get it installed, and I am really happy with it. Evolv, I would highly recommend picking one of these up if you need to replace your stock hose. They are not only smoother but way cheaper than the stock hose. The PTC element isn’t hard to deal with if you know what to do. TEKAY and 1clean00 gave me some advice. I popped the clamp holding the PTC element in and was able to remove the old tube. I cut a slit in the hose to remove the PTC element. I used a Dremel to grind down the lip. You will need to grind the lip off completely, because it won’t fit otherwise. I wasted quite a bit of time trying to fit the PTC element in with some of the lip intact. It fits tight enough that the lip is not needed anyway. Even when it was completely inserted, my PTC element did not fit like in TEKAY’s picture. My PTC element was recessed and did not protrude into the main part of the hose, so the lip would have been useless. I have the MoToTec intake and I was still able to use this hose. It took a bit of work and an extra hand, but that may have been because I had the intake completely removed and just eyeballed it and then tightened it onto the turbo so it didn’t line up exactly. It wasn’t exactly easy, but I feel like if I had to do it again it would be a much smoother process. I have much less skill and experience than most of the members here so if I can do it than I am sure anyone can.
