[TR] TR3/4 Liner Height Protrusion

[TERRY SMITH]

I might suggest using the copper gasket, but putting a variety of spacers (a profusion of old sockets) on the studs, then cinching down until you get the right measure consistently all around the cylinder.  It's really important to get this exactly right to avoid blowing head gaskets "down the road."  When you take off the sockets, the crush on the figure 8 will stay pretty much the way you made it.


Good luck!

With the steel figure 8 gasket supplied, the protrusion is 0.003, which is the minimum. If we change the gasket to a copper one then the protrusion becomes 0.007, which would be too high by 0.002. Obviously the copper gasket is thicker by 0.004.
