Good afternoon,
I am about to buy a 1987 300 sdl. What should I look for? I am having the shop perform a compression test and a car fax. The car has about 154K on it. Is there a website dedicated just for the sdl? I have looked but most w126 websites deal with 420 or 500 with very little mention of the sdl specifically. I searched these forums but the information is general at best and I am VERY new to the diesel thing. I have also checked out the mercedessshop but they also have limited pre-buyer information for the 300 sdl, at least when I searched they did :D
How should the transmission shift, any funny noises I should be aware of when I test drive the car? Any leaks I should look for? I know about the trap oxidizer, but I have not seen a pic of what a trap oxidizer looks like and what the replacement should look like.
Any assistance you can provide would be of GREAT help.

re: Oil pressure. AFAIK, on all Mercedes diesels, the gauge should be pegged ( high) at all speeds above idle. At idle, with a hot engine, the pressure may drop to a little below "2", but return the high as soon as you give the engine any speed.
Welcome to the club!
The "diesel forum" over at Mercedesshop.com is a great place for all your diesel specific questions.
