N62 Valve Stems Seals - What was your cost

[sbarsap]

Damn I paid approx $5700 to have mine replaced a couple of months back that included sending the head to the machine shop.

For $350 a head

This includes:
A thorough chemical cleaning, resurfacing the gasket face of the head, cutting the valve seats with the renowned 3-angle valve job, installing new valve stem seals, cutting valves to ensure optimum valve sitting, precision polishing both intake and exhaust valves (a procedure only we perform), pressure testing, vacuum testing the ports to ensure seats are sealed and double checking to ensure everything is within BMW specs.

Of course this is the price for just the head work no R&R and gaskets ect. But for those tearing down the top of the engine to the heads themselves this an excellent option.

Any idea what the cost would be for 4.6 heads?

Updated seals are red in color

Awesome, can I ask do they remove the springs? If so is that a separate tool or does the one tool (set) do everything. I have a mechanical engineering brain and I can't think of any way that this is feasible so absolute kudos to them and I'm very excited to see this tool in action.

Yes, the springs are removed - All the same tool set. When you see it you'll wonder why you didn't think of it.

Any updates for the kit?

I'm assuming you mean the tool kit? It's only been a week, they need a month or so for tooling.

I know - it sounds too good to be true - but All German Auto (Escondido,CA) claims they will soon have a tool kit available to the public (within a month or 2) that will allow you to replace your N62 valve stem seals without removing the cams/timing.
** I'll keep you posted **

I saw his video (in amazing low-def 240p!) online. I had heard of using a leak down tester to hold the valves in place while you remove the valve springs, etc. as a quick way to change out valve springs from some racers. Never thought of it for this application but it makes sense. Very clever.

Still a whole lotta parts gotta come out to get access to the valves! For me, I'm likely to just drive down to Escondido, drop the X5 off and spend the day with friends! Better way to spend the day for me!
