This is most useful video I've seen to remove the N62 valve cover, and I hope it was there last summer! It looks 100 times easier after removing the cables to the ECU.
I did this with less efforts than what you did. I used the same tool for valves springs compressor. I didn't lift the engine, i didn't remove the cam shaft chain gear, nor the front covers. I just removed the chain tensioners, removed it from cam shaft gear, and took all the cam shaft as one assembly. I just marked the chain position on the cam shaft. And used rope inside the cylinder and rotate the engine to compress it against the valves to hold it up. The last cylinder PIA to replace but it's doable.
Faris, that's genius if it really works! How did you get the Bank 1 tensioner out? So all you did was to mark the chain and sprocket tooth locations and then removed the tensioners and pulled the chain off the sprokets?
Update I just completed my N63 valve seals it was pain but well worth it. Hat off to you sir not using keeper tool to put back valve keepers. If I was doing this job I would invest money again to use AGA tools. They work very well 👍🏻 This is great video.
Excellent, no BS video, thank you Chris !!!! I like your idea of jacking up the side of the engine you're working on. Does anyone think jacking the side might also make it a bit easier to get the valve covers off? I'm getting ready to start the valve stem seal job on my 2007 550i this weekend.
Merci pour ce tuto, je suis entrain de faire cette opération sur ma BMW 650I V8 N62. J'ai pour ma part sorti le moteur sinon les valves sont inaccessibles. Bonne chance à moi pour ne pas faire tomber de petite pièce dans le moteur :)
That’s exactly like how I did the passenger side timing. I just kept tensioner in bc you can’t even get special tool in on that side. But for valve seals I didn’t have air so I used a rope down the spark plug holes to hold valves up. Worked like a charm
I gotta do this on my 04 645 this summer. Any suggestions as to the best parts kit to make this job the easiest? I'm a diy mechanic and never did an internal engine job like this before, but i am capable. I can't afford to hire it out. It's not worth it.
1. How many PSI for the air line? 2. Remove only one spark plug and plugin the airline, the rest of spark plugs are still in, or doesn't matter, right?
There is a way to verify the stem seal had been replaced? I bought my 07 4.8i last summer. Don't see any blue smoke, need to add 1L oil for the whole year. Once I open the valve cover, is there a way to verify?
Hello, I replaced the stem seal valve on my 2009 BMW 4.8 engine, I put the engine on time, I checked it with the timing tool kit, I turned it twice and I checked again and it was fine, then I put everything back together and tried to start it but it only stayed as if there was no gas and it gave me the code 2E6F
@@nathanielhuntley7875 I already solved the code 2E6F, after searching and searching, the scanner marked something from bank 2, I disassembled everything again, I checked the time with the tool to synchronize the time and I realized that from bank 1 the tool entered correctly on (exhaust and intake) but I put the tool on bench 2 and if it came in but only sat on one side and the other was about 1/16 to go down, I released the CAM phases again and adjusted until I had the tool that would sit on the block well without having to push it to sit, arm it back and it turned on the first time
@@ibrahimdelic8958 I needed to disassemble the head covers again and check the time of bank 1, the time tools entered by themselves without having to hit (bank one fine) but bank two the time tool, they entered but from one side if left flush with it I blocked the head as it should be but the other side was slightly raised, and I corrected that the tools of time have to enter and remain flush on their own without having to hit for them to enter, (then I armed myself back and turned on the first time) correct that and it will work (these were the codes that it gave me, 2E6F and P3497 cylinder system deactivation (bank 2) only one code but each one with a different scanner
