This is a link to download a short .mov movie file from my iPhone in a dark garage at work as engine is warming up. last part of video sound is oil fill cap being removed and then put back on. Sounds like timing chains/guides worn out and hopefully not an intermediate lever also.
Any advice is most appreciated. thanks

Need help please, and Thanks in advance. My 2007 FE83, E70 4.8i is at 154K miles, timing chains and guides at their maximum wear point (serious rattling when warmed up). Blue smoke from exhaust after long idle, Valve Stem Seals. I live in northern Virginia. . Should I replace engine with salvage yard version and fix the VSS and VCGs/Chains or fix original engine in the vehicle. Local shops not much interested either way. Any recommendations/referrals is most appreciated. Thanks.

I seem to recall at least one or two guys offering VSS replacements as a service...check out bimmerfest. Might be "bmwoem1" or something??? dont remember. He was near you I think.

Any interest in doing it yourself? I haven’t had to do the chain but I’m about to do the VSS myself. I can connect you to a guy that rents the AGA tools. I figure you might as well try it yourself if you have the time. If you mess something up then you can always go the replacement engine route. If you do get a replacement engine you will still want to reseal it before installing it. I do know a guy that does VSS in North Carolina at the private mechanic going rate.

Try some at-205 to stop the smoking. If the seals aren’t torn, it will fix it up to make it a few more months or years without smoke. At this point you don’t have anything to loose. It stopped my batMobile from smoking when I had a 100k 4.8i.

I also had luck with Lucas calming the smoke. Do not use brake fluid. All of these seal softeners are a band aid, but a cheap way to keep it going a while. I also use it on my f450 powerstroke, with 326k miles. It was leaking oil from the oil pan and cooler, constantly dripping, some at205later and it’s dry.

If you can DIY then above suggestions are good. If you cannot DIY then the economics are against you. For the type of work you need, I have never found any shop in the DMV area that could do any useful work at a reasonable price......

thanks all for replying. I have sent a few emails to knightmaster in New York and a video, hoping he can help, unsure what will come of that. If anyone knows of an indy or person within 2/300 miles of Virginia who can do timing chains and guides and valve stem seals on a 2007 X5 4.8i, 144K miles, I am sure in the need. I have heard and seen some posts that only M62 engines have this problem, but also seen posts of some of the N62TUs do have timing chains and guides issues. I know mine does for sure. You can hear it clearly when you open the oil fill cap on passenger valve cover. I just can not find a person or indy shop who wants to do the work. Hoping some one at this forum can assist. Desperately trying to figure out a solution to my e70 4.8 typical engine problems dilemma. thanks

TriX5. I can do this as DIY, but not the right timing for me currently. No garage at my condo complex, cold weather upon us in Virginia, etc., Willing to pay for an Indy shop or somewhat nearby person to do this work. thanks

What are you hearing to diagnose your timing chains and guide? Have you had your valve covers off to inspect? You can see through the oil cap a bit. I know a master tech that does work in NY, MI, and SC. Come to the warmer weather down south and have it done quickly. VSS can be done in 12 hours or less with an experienced person.
