    • @porscheDIY
      @porscheDIY  4 หลายเดือนก่อน

      I didn’t know the Cayenne GTS shared same engine as the Macan, but looking at it, they in fact look identical. When you search for coolant vent parts on your Cayenne (I just did), you’ll find that your engine uses exactly the same tubing PN 94610602660. So, I would think you’d have the same issues. Hey, thanks for letting us know!

    Hello gentlemen, please excuse me. I would like to ask a question after watching your interesting video .becausei have the same issue witth my macan S 2014... my question is... does this hose have a specific function behind the engine? or the gearbox back there conduct water??? It's strange to me why the hose has to go so long to the engine and back again... i wish you can explain to me ... thank you... 🙏🏼

    • @porscheDIY
      @porscheDIY  4 หลายเดือนก่อน +1

      This is a vent line. Its function is not to transport coolant to parts of the engine or transmission, but vent excess pressure/coolant back into the vent valve and coolant reservoir. I inspected this line with a borescope and it goes from the front of the engine to the rear… it makes a left turn, goes to the left side of the engine, makes another left turn and then connects into the vent valve.
      As far as a good explanation, I don’t have any. I have been driving my car for the past 1000 miles with no issues. Others that have done this have not had any issues either. If you are concerned, you can get a borescope (they are cheap in Amazon) and inspect the full line for yourself.
      The Macan Forum member that discovered this and develop this repair method had disassembled the engine parts necessary to get full access (including removal of intake plenum). When he was about to replace the tubing, he inspected the full line and realized that it made this strange loop without connecting to anything else.

    The OE coolant vent pipe lasts on average 50-60K miles in my experience, maybe longer. I just replaced mine and it took about 2 hours all said and done. I like your DIYs but not sure if I like this one. Every 50-60K miles its not a bad idea to clean the intake manifold and inspect valves for carbon deposits anyways so I think I will keep with the factory design and replacement. But nice video!

      Just curious, how bad was the carbon build up on your valves at 50k?

    • @porscheDIY
      @porscheDIY  5 หลายเดือนก่อน +1

      Mine looked OK at 140K miles. But it is a bad design and I didn’t want to continue to take the risk. Why keep replacing it when you can solve it for good. That won’t prevent you from taking the intake plenum out to clean the valves. As a matter of fact, there are less components you will need to take out just for valve cleaning. But, I totally respect your decision… Are you seeing a lot of carbon deposits at 60K miles? A solution for your carbon deposits is installing a meth injection system, to not only gain performance, but also to keep the valves clean. I’m planning on taking out the intake plenum over the summer to clean valves and potentially install a meth injection system. Thanks for watching and for your support!

      It doesn't have to. come out. I would recommend that you cut the hose/tubing as much as you can get to, and secure the rest with a tie wrap. I just removed it so that it wasn't dangling and making sounds when hitting stuff. As long as you secure it, you will be fine.

    I dont get it. You bought the part and spent exact same time with clamping hoses you would spend with removing the manifold?!
    This plastic tubes are almost in every engine and last at least 10 years. So you dont want to do this job in ten years again?!

    • @porscheDIY
      @porscheDIY  5 หลายเดือนก่อน +3

      The life of this tubing is determined by several factors… it lasted 10 years, probably more, in my specific case, but others were seeing very premature failures. Which leads me to believe that this follows more of a random failure pattern/model.
      Since it is random, failure can’t be predicted, and hence we can’t say with any certainty that the expected life of this component is 10 years.
      As far as the time it took to do this, there is no comparison. It takes a few hours to take everything you need to take out to replace this tubing per OEM and put everything back… as opposed to about 1 hour to fabricate and install the hose. Obviously I took longer because I was recording, repositioning the camera, explaining, etc… but with focus, this is less than 1 hour.
      For both, you need to remove the air hose and throttle valve… just that with this mod that’s the only thing you need to remove… for OEM install you need to remove and reinstall a hundred other things…. It was worth it to me…

      ​@@porscheDIYMine is also a 2015 and I am on 183k km. The factory pipe lasted at least 4 years as the year of manufacture is 2019. It broke last week so average lifespan based on my car is 4-5 years. Right side exploded in the bend. I chopped out the remnants and replaced with rubber hose to get it home. Left side cracked in the same area the next day so I replaced all of the plastic pipe with rubber hose and brass fittings. I didn't want to disturb the vac tank or high pressure fuel pipe so I cut the remaining plastic pipe in sections and fished it out. I then fed the rubber hose in via the rear and put some padding where the factory clip is on the metal bracket and ran the hose along the same route. Plenty of room under the secondary air pump. I used constant tension spring clamps to avoid twisting the fragile plastic fittings still in the cylinder heads and for simplicity of assembly in the cramped space
