This has to be one of THE BEST how-to videos I’ve ever seen. I’ve worked on Chevys, Porsche’s, Miata’s, Trumphs, Isuzu’s, motorcycles and mountain bikes of all kinds. This is a VERY complex project for the home mechanic - but NOT impossible, if you’re deliberate, prepared, and organized. Your video is well-lit, great camera angles, and EXTREMELY well narrated. You took the time to edit over a couple of spots for clarification, and you took the time to show multiple approaches. You used the RIGHT tools, and took the time to demonstrate alternate methods, and danger areas. I’m sorry that this is such a niche repair, because you serve HUGE numbers of views for what you’ve done. For all of us who like to do our own work, all I can do is say thank you for taking on the additional challenge of filming this complex project. Mad props, my brother!

It wasn't easy, it took a long time but one more car saved from the scrapheap! Thanks!

i have an 05 545 and had the valve cover gasket issue first then coolant and alternator bracket but looking back it might have made more economical sense to to just have someone take the engine off and do every single seal plus valve seals and adress carbon build up cuz 40k miles later i have issues with they secondary air system too , just my 2 cents

So i changed the abs module out, first one no difference, second abs module had a reconditioned tag on it. This one seemed to fix a lot of electrical issues. The three warning lights are still on tho. So i replaced the abs rings on hubs and brake discs. Still no speedometer and three lights. My scanner still says wrong gap driver side and wrong abs sensor on passenger side. Since i have tried three sets of abs sensors, i was wondering if perhaps the sensor that goes into the hubs, could be on wrong sides? Any thoughts?

[@helmutvorlaufer6647]

I have dun this job on my 08 e62 550i with cams in place with a similar tool as the AGA tools however it would have been very usefully if I had seen this video before I started the job . I think the guy has made a very informative how to video ,it sounds like he is a fellow South African

[@christophersweet4898]

This guy rules I could listen to him all day

[@rcodepaul]

Top rate job Eco. A thousand thanks from California. Our E60 N62 had quite a few differences until we got to the cam covers, but from there in, super similar. We had the smoking after idling deal and held off this repair with Oil Saver for a couple of years but it got to be too bad even with that. All the great detail, the tool sizes, the torque call outs the detailed explanations made it much easier than had you not done this. Plus the confidence to tear into it was hugely boosted after my son and I watched this. I did watch ShopLife KZbinr's E60 N62 cam cover gasket replacement video as well to help with the E60 nuances. Neither he nor you pointed out a problem we encountered. The dreaded spark plug tube reinstallation. Made the mistake of fully seating them in the head first and never could get the cam covers seated. Went online and found a tip - only partially seat them in the head, so they fully seat in the cam cover as you work them in. Magic. I agree with Kuehne, it's a very complex project but with your video, some organization and a boatload of determination, it's doable. Our 300,000 kilometer 07 550i now purrs like a kitten and roars like a lion. Thanks so much.

[@ecologicaltime]

thanks for your comment and tip, wow thats a great mileage! well done

[@rex7486]

The time you have taken to film this is amazing, and appreciated! The "tips" you provide a really handy. The only comment I would make is that the Valvetronic motor should have the tension on it released before unscrewing. The "Clack" you hear on the first one is the spring unwinding very fast, and it can damage the gear that it sits on... (speaking from experience). To release the pressure, you use a Allen Key (4mm) to insert in the top and wind clockwise until you feel a bit of resistance.

[@ecologicaltime]

thank you, thanks for the great tip!

[@sumeetkakroo]

Best DIY video, wish I could bring my car to you..

[@Nisipd]

You can do it without removing top timing covers if you just losen the chain tensioners and slip off the chains. If you initially put the engine on time and mark all cams and crank, it can be put back without timing tools but requires some skill and understanding about how engine timing works. If you use compressed air method the engine might turn on you so be careful Safest method is the rope one. I used the exact same spring compressor tool and used non magnetic screwdriver and grease to put the keepers back. I found out that the keepers are easy to mount from the same side of the valve and just rotate the first one around the valve stem to the opposite side.

Seems like you can use the other studs to rig/screw the lever in place to hold tension on the springs & let you keep both hands free.

Anybody can make a decent video on how to do something simple like replacing a PCV valve, but simplifying the complex is the hallmark of a true expert. Philip Baron has provided us all with fantastic resource to repair an issue that every owner of BMW with the N62 will be faced with sooner or later! I have two cars with N62's that need this repair (2006 750Li and a 2007 550i both with over 150k miles).

Also what is the name of the gasket in the solenoid housing - not the circular one on the solenoid itself but on the front of the valve casing? Thank you so much this video was fantastic.

[@onesikm3]

Hey so it loooks like it is not necessary to have the timing lock tool during disassembly ? Mine is still in the post and I’m ready to remove the valve covers. It’s my understanding when opening any engine the timing specific tools are not required for the tear down…. Great video man thanks it’s going to help me a ton !!!
