painful to watch removal of cap!

@IAmDistracted 4 года назад

It's stronger than I thought... I could have just forced it off.

@stevew914 3 года назад

Looks to me like you may have ripped the diaphragm with your screwdriver.

@IAmDistracted 3 года назад

I think I did, but it was cut a bit before... I just opened up the wound with the screwdriver. :)

Hi bro....thanks again my porsche cayenne turbo V8 4.8L Already changed pcv part after fix it Around 1 week then check it again & removed air speartor hose still oil coming out what is the reason..what do u think

@IAmDistracted 2 года назад

Hmmmm.... there could be a little in there even when it's fixed, but if there's a lot, then maybe you're getting too much pressure in the system somewhere that is blowing past the diaphragm. Hard to know without tearing it down...

@MattHessen 4 года назад

Sooooo... just to verify; did this work for your problem? My twin turbo has been hesitating under heavy acceleration as well (for a little while now) and just threw a P0492 insufficient air flow code at me yesterday for the first time. But i will be stoked if this fixes the hesitation problem!

@IAmDistracted 4 года назад

I found out that the breather hose was cracked too (amzn.to/31RDJJt), so I changed that out (and this one to be sure: amzn.to/35a8FXk) and it works great now. Except when it's really hot and the engine has been running for a while. Then it still hesitates under full throttle...

Matt Hessen it could be knock sensor. Its common problem to every cayenne

@next_do0r 4 года назад

need to change the title, how to open the cap... This video is very helpful.

@IAmDistracted 3 года назад

lol Yep!

@kawalt Год назад

You stuck the screwdriver through the diaphragm. That wasn’t an issue before you did the damage. Lol

@IAmDistracted Год назад

Yes, I made it worse with the screwdriver... but it was already leaking because the diaphragm was old.

@BkNy06 4 месяца назад

I think I have a similar issue on my 04 cayenne S. There’s a lot of white smoke coming out of the exhaust. Should I give this a try?

@IAmDistracted 4 месяца назад

You can try it... it might be cylinder scoring if you are in a cold climate. The S engines had this problem - the Turbos don't because they have extra oil passages inside.

@OverlandUnderBudget 3 года назад

So did this fix your issue?

@IAmDistracted 3 года назад

This ddi fix it a bit, but it still hesitated a bit on real hard acceleration , so changing the spark plugs out fixed it 100%.

@andyfox1979 Год назад

Should my AOS be making a sound? I can hear suction or air coming out or something.

@IAmDistracted Год назад

I think a little noise is fine, but if it starts to whistle, then you probably need to replace it.

@mazent8084 4 года назад

Hi thank you for the video & if not change it what will happen,,, thanks Again

@IAmDistracted 4 года назад

This can fix the hesitation issues that a lot of these Turbos have.

@mazent8084 2 года назад

Thank you Again...

@GoFast4Me Год назад

Wish it was the same for a 2009... cant find the part!

@IAmDistracted Год назад

Dang! I'll see if I can find something...

Sorry, I don't have a head gasket video ... yet.

did separator make noise? like bbbbbbiiiiiiipppppp!! my cayenee 4.8s seperator make noise at spot where fix in your video.

@IAmDistracted 3 года назад

That sounds like the diaphragm in there is broken and leaking, so yes, I would say this would fix that.

@user-ls1fl9kd3o 3 года назад

@@IAmDistracted should i replace separtor assembly? or replace only that parts?

@IAmDistracted 3 года назад

@@user-ls1fl9kd3o If the sound is coming from the black cap area, then you can just change the parts. If it is coming from the joint between the assembly and the motor, then maybe change the whole thing.

@gdunn2059 4 года назад

took half the video to remove the cap LOL

@IAmDistracted 4 года назад

lol Tell me about it! I was paranoid to break it, but it's actually pretty solid.

@DumbCarGuy 3 года назад

should have been a 2.5 minute video. that first 3 minutes was worthless unless you like watching stress

@IAmDistracted 3 года назад

Well to be fair, I did speed it up a bit, so it was faster than if you watched me do it in real time... but ya, some people like watching stress.. :)

@stephenmcdowell9210 3 года назад

Every video I watch on Porsche cayenne there is something wrong 'are these vehicles a bundle of crap 'I never see anyone fixing my vehicle the Lexus rx 'so what does that tell you 'it means Porsche can't compete with Lexus ''Lexus is miles in front in cases of realibility and owner satisfaction 'why would anyone buy these junker vehicle s 'you would be spending most of your time fixing the bloody thing 'a just think of the expenditure as well 'not for me thanks I'll just stick to my Lexus rx thanks

@IAmDistracted 3 года назад

Hey there,

@bostonbikebits6539 2 года назад

It might just be that there is little point putting up a video of how to fix something when there is nothing wrong. Very few people have Lexus rx's because they are Lexus rx's and nobody wants them. Personally I would rather have my thoroughbred 4.5 litre v8 twin turbo 450 bhp Cayenne than any soul less boring Lexus. Each to their own and all that.
