Good repair in south LA?
 

Hello.
I would like to find a good repair shop here in southern LA (Palos Verdes) for my 1987 300TD. I have been having several small issues with the car such as an aux fan issue as well as the car, I think, needs a tuneup with some of the valves. I think one is called a "Diesel Valve" that I was told to get retuned. Does anyone know any shops around soutern LA (Rehdondo, Torrance, Long Beach ect...) that know a lot about working on these old diesels?

Thanks for your time.
