I just read the thread on the late 80's (1987, 1988) 300D's with the weak head. Are these the ones with the 6 cylinder engine? What year did they improve upon it? I was considering getting one, now I'm concerned. Does anyone know what was the last year of the 5 cylinders? Did they have a 5 cylinder in the newer (non-126) body style.
