AGA valve seal tool

I'll be performing the repair over the next week in my spare time, so here is a journal.

Day 1 - drivers valve cover removed, oil feed line removed. Yellow tips are the brushes that come with the kit to prevent debris from entering the oil system. About 3 hours to get to this point - spark plug tubes were stuck to valve covers slowing down progress.

Step 2 - tool installed on bank 2, first rocker removed. Next step is to rotate to tdc, apply air pressure, remove keepers and change seals. To say this tool is awesome is an understatement - it's an absolute joy. Below is the intake with pressure on the spring, post rocker removal...absolutely brilliant tool.

Better shot of the "short" foot on #5 intake; fits like a glove.

Spring, retainer, keepers, and rocker installed. Doesn't get much easier. Now to do it 31 more times.

Amazing post. Please keep it coming. One question...Does this kit come with instructions?

Yes - in PDF form and via YouTube. Martin (the owner) did a fantastic job documenting the procedure. No one else out there has such good documentation for the cost of the kit.

I have seen his video for the secondary air kit, but not the valve stem kit. Will have to look it up in YouTube. I need my valve stem seals replaced. Did the valve cover gaskets, but not stem seals. Will be doing those soon.

Finishing up the exhaust on cylinder 5. The tool is great but progress slow. Intake are much harder to reach than exhaust. The effort saved by not removing cams is somewhat lost on the time spent working the intake valves.

Day 2 synopsis - I've put a bout 5 to 6 hours in today, and completed the number 5 and 6 cylinders. Keep in mind this includes a learning curve for the toolset, and the best way to do things, and recover dropped parts. Additionally in a few places I found using a screwdriver with a dab of grease easier to install the valve keepers than using the supplied tool. Note that I am not a professional mechanic, however have been turning wrenches since I was 15. If you are a home mechanic, this job may be too much for you.

The alternative is to spend $2500 with bmwoem1 if you are on the east coast, and have it done the old fashioned way - I can tell you this, after this much work into it thus far, you are much better off paying a professional mechanic to do the job rather than tackle it yourself, unless time is no issue and you have a spare vehicle to drive (or you are just a stubborn German like me). If you are on the west coast, DON"T EVEN HESITATE to go see Martin and gladly pay him to do this for you...trust me on this one.

If you are dead set on doing this yourself, get to harbor freight and pick up the fuel line pliers, and some long straight needle nose, along with 45 and 90 angled - well worth the $25 you'll spend, and a necessity for the job.

All in all I am making progress however this is a big job. I'll post updates as I make more progress. Overall, the kit really is well done and very well thought out, I give Martin tons of credit here, the guy really knows his stuff.

Looks like you are well under way. What is your best guess on hour many hours the complete job will take. I think my guess of 24 hours, might be way off? I am also curious on how many miles the engine has on it?

Good Luck!

Not sure on the hours, I've been working on it off and on as I have time. Going to try and complete the last two cylinders on the drivers side bank tonight. Car is just over 107k however the problem starts to develop early - there is a huge difference in valve seal construction from old to new. I can only presume an incorrect grade of rubber was used in the initial design, leading to them becoming brittle over time from the engine heating cycles.

Working 7 & 8 tonight - MAJOR time saving tip - remove the hood struts and stand the hood straight up. I'm an idiot for not doing this earlier, night and day clearance access.

Going the realoem1 route on this one. He's less than 2 hrs away and I will feel confident its done right the first time. If I absolutely had to do it myself, I'm very confident I'd pull it off though. I looked at the instructions on the aga site and its still looks very involved, despite the tool kit. Hats off to you for rolling up your sleeves and digging in. I admire all these contributions with pics and everyone on here who makes it happen. Thats loving your ride.

The worst part of it, in my opinion, is the removal of the valve covers. Mine did not want to come off, and you have to be careful not to break anything in the process. Otherwise it's not such a terrible ordeal - good lighting and standing the hood straight up are simple, yet key factors in making this easier, and saving hours of time.

Martins tool set is really fantastic, I can't stress that enough, it's obvious he thoroughly thought out the design and fit and finish. That said, at this point, I'd still rather do it this way then remove the cams. I can see how someone using this tool on a regular basis can get into a rhythm and really shave time on the job, making it more profitable while being less intrusive to the engine. Less things you have to take apart, less chance for error, period.

I will be spending this weekend finishing up. I don't know that it would be worth my time to do this on the side for what is charged...if you miss something there is huge liability if you suck a valve into a cylinder or even accidentally break a sensor.

Are you noticing any difference between the exhaust seals and the ones on the intake side? Many other cars I've done this job on (haven't done any E65/66's yet) only needed exhaust seals as they got much hotter not being constantly cooled with fuel and air? Would like to only have to change 16 when the time comes if I can get away with it.

They are all fairly equally shot. The rubber hardens and expands. Considering how much effort there is into getting to the point of changing them, it would be foolish IMO not to do them all.
