Replaced the valve stem seals on the the 06 750 this weekend. It was a job and a half the hardest part was the keepers. I attempted to do it alone but quickly found you need a helper on it.
But you could see the old seals were in poor shape the rubber was really hard. Shame on BMW for this.

Keif had one in the DIY section that helped greatly. I got instruction from alldata as well. Got a print out from a buddy. It took 2 of us to do mine and it was 12hrs easy.

Keif,
I have to do valve cover gaskets at some point, how much more work would it be to do the valve stem seals?

Yeah it was around 12hr. Now I couldn't have done it in that time alone. It helped my buddy had just done one a few days before. We had air and lift. One thing we have found you can remove the cams with out taking the vanos off. Keif I assume you had as much fun with the keepers as we did. Did you figure out anything other than a small screw driver?

I cussed up a storm dealing with those stupid little spring keeper things. A small magnetized flathead screwdriver and plugging all oil drain holes, with an extendable magnet on standby was what worked best for me, I'm definitely interested to hear about other ideas though! To keep the VANOS adjusters on the cams did you just de-tension the chain a lot to get it to hop over the teeth on the gears? That could possibly prevent having to remove the timing covers, and make you have to mess with the cam timings a little less, which would be great...do you recall if there was enough clearance to avoid removing those upper timing covers? Did you check the timing using the cam timing jigs when you were done? If so, do you know if you slipped any teeth on the crank, or did the chain stay in place pretty well?

It's really a good bit more work; it's not a small job, although if you can avoid removing the upper timing covers, I suppose it would be a little smaller job, but still a pretty flippin big headache.

Yep they are a pain my buddy actually had to take over on that. We used the magnetized pocket screw driver with trans jelly on it. Yes if you back the adjuster out you should be able to walk the chain off the vanos make use you paint mark those cams and chain. Not still have to get the covers off or you dont have room in my opinion but I think I would try to do it with out taking off the covers next time. We are going to do a 5 sometime soon and we will try then. I did use the timing jigs and double checked both cams with them. The chain will stay in place on the crank but you dont want to drop it in the head so we zip tied it off to hold it up while working.

I have been trying to come up with a better idea than the screwdriver for the keepers. I am thinking tweezers modified on the end to cup the keeper that way you can load it and snap it on the valve. I might order a valve retainer next time and try to cut in and make this tool.

Sorry I didnt take pictures of the job but was under the gun since it is the wife's daily driver.

Did you check timing or simply put the chains back where they were? I'll need to do this, possibly this summer.

EDIT: never mind, looks like you addressed my concerns above - paint marking the chain to the gears and zip ties. I presume TIS will give me specs on re-tensioning.

You will lock the crank down with the timing pin and lock the cams on the head you are not working on with the alignment tool while working on the other head.
The tensioner has no adjustment it is hydraulic you have one on the left side and one on the left. The drivers side is in the intake and the other pass is below the cam covers. You only need to remove the one on the side you are working at at the time.
I also put the cam tool on to check the head, i just worked on after i put the tensioner back in.
This job can be a complete pain in the rear.

Ah I see - where did you acquire the timing tool? generic or specific to BMW? I've just bumped up my viscosity a tad since I noticed the oil at long idle issue. Not looking forward to the job but it needs to be done, and I have other cars I can drive while this is down in the garage.

You are lucky to have other cars to drive if I was in that boat I would have taking longer.

That is a good tool i have the snap on version but it will not work on these valves since it multi groove keepers.

Wow not a cheap tool either. Still a DIY savings, but not like you'll use the tool again anytime soon.
