keep a tracker valve diaphragm handy, and a compressor belt. Its a weekend saver

Yep, put a new belt on when I installed the motor. What is a tracker valve diaphragm?

[Stevebbc]

I found out about the tracker valve. Hadn't heard about it b4. Thanks for the info.

Heard a lot of good things about the latter opti s. Cousin had one he messed up running cheap oil in it, so make sure u get the good stuff.

run good opti oil, and run Merc carbon guard/yamaha ring free. Keeping teh carbon buildup out of an opti is the key to making them live.

Yep, the compressor, injectors, and everything else on these motors need the good stuff. It burns so little oil, total cost of opti oil vs black max is probably about the same or less.

According to my research, it was the early 3.0 motors that had issues that were eventually resolved but the 2.5 litre motors never had those problems.
