I just checked them and they are all there. My thinking is that, barring a bad injector, if one failed, it would be due to fatigue after 30 years of heat cycles and harmonic vibrations and that the others would not be far behind. Mine are ok as per looking through the hole and poking the balls with a stick so I guess it is a moot point.

I would be curious what Mauri H. bases his opinion on. NOT THAT I AM SAYING HE IS WRONG!!! He may be very correct, so I can learn something, how dose he know? I am not familiar with the name so please pardon my ignorance.

He is a major modder and racer in Finland's "Superturbo" hobby.

The Mersu forum has many great threads, you should spend a few hours looking through it. Even if you can't read Finnish (who can), there are some very good pictures scattered around the forum.

One of his creations. A ~400hp 300TD.
