HOW TO: CCV valve replacement BMW 7 series (e38)
HTML-код
- Опубликовано: 27 сен 2024
- My car has been blowing blue smoke upon startup and one of the likely causes is the CCV valve. There is a diaphragm at the back of the intake manifold that will eventually fail, and when it does, it allows oil to go places it shouldn't, mainly your combustion chamber.
So in this video, I will be showing you how to replace this part WITHOUT removing the intake manifold. Also, I show you how to deal with a stripped bolt because I love you all so much.
Roll up your sleeves, and let's get ready to do WORK.

Well made video! By the way, the bolts for the CCV aren't torx bit, they are RIBE R8 bits. If you look on the face of the bolt it says RIBE, which is very similar to torx, but not the same. That is one of the reasons that these bolts are commonly stripped out on removal is because the torx T30 has sharper lobes that are easier to strip in the RIBE bolt.
Also, sometimes you can spray a silicone spray on the joint between the hose and the plastic bits and use a screw driver to lift up the edges and let the silicone seep in a bit and sometimes they'll come off a bit easier. :)
Yeah those hoses were petrified! Thanks for the info on the RIBE bolt.
This video is the best because it helps us deal with the emotional part of the repair as much as the actual steps for the repair. We all are in it together lol.
Yep, being a YT mechanic is a rollercoaster of emotions
A man has to do what he has to do. Perseverance prevailed and the part came off mission accomplished.
Yepppp, thanks for the support!
yes man, I stripped torx BS too, I will have to do what you have done, this is a great video you have done, I owe you thumbs UP !!!!!
Thanks for the kind words and thanks for subscribing!!!
Bro I like the solutions you provided. You gotta do what you gotta survival mode on this beauty. Great video 👍🏽👍🏽👍🏽

Hey, thanks for the video... I did the same thing this weekend, 6 hours yesterday, 3 hours today. The only difference was I used a power drill to distroy the plastic tunnel to clear the way to that bolt. The CCV on my car I believed was the original. I owned the car since 2004. The bolts are pretty siezed up and took larger force to get loose. All the smaller special tools were too weak. It took a T30 on a 3/8 wrench to loosen the first 6 and strip this last one... wish I had paid attention to the reply below about the RIBE R8 bits... I guess it's all a part of the cost of owning an older BMW... lol
Drill would have worked for me if I wasn’t ham fisted. I didnt want to hit anything else by accident. Every job is 1 stripped bolt away from being a nightmare
Has anyone of you ever tried to replace the lone membrane only? It's doable and all you need is new CCV valve in your hands. You just open the round cover that holds new diaphragm by gently unlashing knobs. Carefully.
You have to do simmilar on engine. No need to tackle with screws in the back. I have a M62B44 in E39 so maybe there is a bit more space there, but both engines/cars are perfectly doable.
I read about it but decided against it since BMW plastic on a 200k car is about as robust as the economy right now
@@ARPerez 50/50 agreed
Nice Job
Thanks
PCV / CCV . I've always known them as PCV valves.
Good instructions! What was your symptoms for replacing it? I think mines the original?
You had arrows to exhaust! Was it smoking?
Yeah the car was blowing smoke on startup after sitting for a few hours. So far it’s fixed!

Just take the manifold off bro
Thanks! I have a 2001 BMW 740iL and had the same issues covered in your video. I even had the exact same bolt stripped out and had to follow your tips for removing it! 7 hex head bolts later, mission accomplished! Thanks for the great videos - challenges included!
Hell yeah! I'm glad it worked out! Thanks for supporting the channel!!!
I find this DIY one of the best I have seen, very clear illustration, good luck
I thank the lord for mechanics like you Mr.Perez, not just anyone can work on these cars. Most of all, your attitude is above & beyond, & ur a true mechanic. I thoroughly enjoy your videos. I’m a trained & certified Porsch Audi BMW tech that spent well over 10 years at the dealership, you are the real deal man. I’m way older now, but I”ll always turn to you for knowledge. My 740i’s name is Dora, means gift in Greek, another story, lol. God bless you AR, & THANK YOU!
Oh man that is the coolest/nicest comment I’ve had in a while. Appreciate your support and I hope yo bring more e38 content soon!
Thanks for the video this is exactly what was my issue I thought my engine was bad. Only have had my 01 740i for 4 months.
🙏🏽 glad you found some value! Share it with a friend!
i would say glue the new tork scews into the new piece only a touch of glue refit breack the glue when tightening . all 7 back in .
True
Holy shit my mechanic took nearly all my engine out becouse he couldnt get to the bottom screws ,so he took everything out to get to it Inlet manifold bits all over . cost me£ 357 pounds uk, about 500 dollars all day work 7 hours . i wish he would have seen this .
Yeah but it’s a PITA doing it the way I did it
mate labour is so cheap there! i'm a mech, after doing this on a customer's car, i'm looking for someone else to do it for me!
