New 450SL Owner question on oil pressure gauge

[pdalporto]

I just recently bought a 1979 450SL which I am totally in love with. I have done minor repairs on my Aerostar van (starters, alternators, power steering pump, radiators, etc.) so I am pretty sure I can work on this vehicle myself.

The oil pressure gauge does not work at present. The previous owner said there was a leak at the instrument cluster, so he took it in and the MB mechanic just capped off the hose, instead of fixing the leak. I would like very much to have this working. So my question is, do I have to pull the whole dash out to get to the connection or just the instrument cluster?

Any help would be appreciated.

The steering wheel needs to be removed and then the instrument cluster can be pulled on - pressure fit - need to disconnect oil gauge, speedo etc to have complete access - good time to replace bulbs and maybe get instruments refurbished. Good luck. There are a number of good manuals: Chiltons, Haynes and MB Chassis & Body manuals plus MB Service manual for V-8 engines: M116 & M117 (I got my MB manuals on eBay).

Thanks for the input. I got my Haynes Manual today, and I must say it certainly enhances the MB Service Manuals. I will be working on this tomorrow morning, and hope that I can get it done in a day....

Well, in perusing all the manuals I have (both MB and Haynes) I can't for the life of me figure out where the line from the gauge to the engine goes. Is there a diagram in the MB manuals that shows this line? I really don't want to start pulling the car apart until I figure out where the line is and where the mechanic actually capped off the line.
