1971 280SE (W108)

I bought a 1971 280SE (W108) with a straight six fuel injected engine with auto tranny about 2 years ago from a junk yard. Amazingly, the car is complete but had a blown head gasket. I am finally getting ready to replace the headgasket but really needed some thoughts / feedback from anyone who has done this before.

I would like to replace the headgasket, install new valve seals, new water pump and replace all the manifold gaskets.

I will post my questions to you in phases as I move along this process and would be very Greatful for any help or advise you could provide. I don't have a lot of experience, and am limited in funds but I am patient and willing to learn. I will complete rebuilding a Datsun 280Z (L28) engine in a few weeks and I think the Mercedes 280SE engine rebuild will be somewhat similar.

So that being said, here are my questions:
  • Does anyone know if there is an online service manual that I can download?
  • Are there other special tools other than the 10mm to take the head bolts out?
  • Besides the headbolts, I have to set timing at TDC? , mark the cam sprocket where it aligns with the timing mark on the chain? ,
  • Is there a trick that you use to wedge the timing chain?
  • What else do I have to loosen besides the headbolts?
  • Should I leave the intake manifold attached to the head and remove later?

Is there anything else I need to know as I get ready to pull the head out?

I am in Hawthorne, CA. If someone is nearby, feel free to contact me. Maybe you can come by and give me some advise. You don't have to get your hands dirty.
Thanks In Advance!
