The shop that did it for me used air applied to cylinders, and they have that AGA tool set. As for the warranty, i have Alpha Warranty Services alphawarranty.com , purchased it with the car 2 years ago, and it did paid off now with those valve stem seal replaced., good that i got it as if not i had to do it myself. Thanks for those videos.

https://www.homedepot.com/p/HDX-48-i...8OPB/206802336. Standard ones fit into the spark plug hole with ample space around it. You just cut off one tip end of the bungee cord and burn it with a lighter so that there're no frills. Here're the specifications of a standard bungee cord. Cord length (in.) 48 Cord thickness (mm) 8 Cord width (in.) .315 If the shop used the AGA or BST tool, clearly they didn't remove the cams. The purpose of these tools is to change the valve stem seals without disassembling the engine further than the removal of the valve covers. No cams removal and such. Shops therefore make more money as they do more valve stem seals jobs in a much shorter time. For this reason it doesn't make sense not to do the valve stem seals if you're going to remove the valve covers - you've already done 80% of the valve stem seals process. They're right there staring at you and all you need to replace them is the $350 BST tool and a $2 bungee cord So if you're chasing vacuum leaks and going to change the valve covers and other seals, why stop there if you know about this process? I didn't know when I did my valve covers twice chasing vacuum leaks, and what a waste of time, money and energy as my X5 still smoked on extended idle of 10+ minutes! And it's not like the valve stem seals last the life of the engine.

No Rope (or Bungy) needed

No rope (or bungy cord) needed is needed. I learned this from one of the mechanics at AGA; I mentioned this earlier in this thread (quoted above). It isn't really necessary to use compressed air, insert rope or a bungy cord. As long as the piston is brought to TDC, the valves will rest quite nicely on top of the piston, only dropping a little bit more. Without compressed air in the combustion chamber, there's no chance the engine will turn over, so no need for the Timing Chain Lock Tool either. |

Valve stem seals done! Engine timing perfect. Buttoning up the engine now after replacing all other seals and gaskets.

Elring 199440 made in Germany, from Europarts. They're the improved version in design and material over the original factory ones that I replaced.

No Rope (or Bungy) needed, continued

You raised the issue of the camshaft balancing lobe on cyl #2. I did the valve stem seals on an 2008 X5 with N62TU engine; #2 had no balancing lobe as described in the AGA Kit (manual manual in error), but did have a balancing weight lobe on #6 (not described in the manual) that I had to work around. I've not seen anyone else describe this anomaly, but did confirm it with AGA tech support. AGA's kit instruction manual is in need of some updates and revisions.

I understand the OEM ones are also improved. Some folks use the ones from the N63 engine as they're deemed more robust. I chose Elring 199440 since that's what I see being used in the AGA video and almost in every DIY videos I've seen.
