The silicone around the tension bolts is mandatory.
I hope all you RX8 engine guys are aware of that.
You don't need to tear down the engine. Just take one out
at a time and apply the silicone and replace it.

Hi Paul,
why do the silicone bit? Do Mazda do this?
BR, Dave McC

Unlike in the car we run the engine at a steady high RPM at high power.
Sometimes this coincides with the resonant frequency of the tension
bolt vibrating in the violin string mode. That has led to fractured
bolts and an internal leak in the cooling system. The silicone
spiral around the bolt solidifies and dampens these destructive
vibrations. Standard practice for race engines around the world.
No Mazda does not do it.
