Does anyone know how much I should pay for a valve adjustment in an 85 300td ?

Not sure but I also need one and I have the same car as you!

I would guess around two hundred dollars. That's for labor, parts, and tax.

Depends on the indy. When Joe M was in buisness it was $100.00 out the door and included the valve cover gasget.
It was a sad day when he went out.

I was one of his regulars and then he moved south and I cannot reach him at all. Anyone have contact info?

Appreciate it.
