Dr. Counts,

FSM does not state anything about the use of a spring compressor for these valve springs. Have you done this on an om 617? Is this a suggestion to simplify the process?

Doctor? I'm no Doctor - and I don't play one on TV either. No PHDs here - just a basic B.S. in engineering.

um, nope. not needed, the valve springs are held down by threaded adjuster nuts. two 14mm wrenches and maybe a crecent wrench if you have trouble with the spring turning (there is a hex shaped spring cap to hold onto with the crecent, or your hands...that's all I needed to pull the springs off!)

Are you guys saying that by the time you have the lock nuts and caps off of the valve stems that the springs aren't under any compression, hence no need for the overhead spring compressor? Are the valve stems really that long?

I admit never having used the spring compressor on an MB - though I've used it on a BMW, a Porsche, a few Japanese engines, and a couple of American engines. I just assumed that the springs would be under enough compression to require the tool.

But then I've never disassembled a setup quite like the one on these MBs before. Weirdest looking setup I've ever seen...

Good to know the compressor isn't needed - that definitely simplifies things. In that case I'd definitely replace the seals and check the guides while the engine is out on the stand.

Yea, that's right. You just need a little pressure on top to get the nuts back on, IIRC.

Has anyone done valve stem seals lately? I have removed old ones from dead engine and they are very hard /plastic. Seals I have done before were much softer. Are the seals soft when new and can they be put on the guides without any special tools?

Now.. where the HE11 am I gonna do this!?

anyone with creative insight on where to find shopspace?

valve stem seals, oil lines, and oil pump housing AT LEAST! those are SO EASY TO DO OUT OF THE CAR! a total BI@$ inside the car.
