I'm still curious to know if the builder knew the engine was going in a
Tiger... and that the Tiger uses an electrical fuel pump. In my first post
I eluded to this. I mean if the builder thinks gas leaked in to the block at
the mechanical fuel pump then he's caught right there.
I think Allan needs to ask questions of the builder in a ordered way so as
not to tip him off, but see the builders "logic" or lack of. In situations
like this people often say, "something smells fishy." It this case
something doesn't smell "gassy."

Hello all,
A crankcase full of gasoline seems odd. How does a carb of any type
overflowing for any reason not produce hydrostatic lock in a cylinder with
the quantity of fuel described? What path to the oil pan is open to gasoline
through the carb? In a properly built system; there is no such path. I think
gasoline in the oil is not the problem leading to cam bearing destruction.

Allan,
There are just too many red flags to pin the cam bearing damage on a crank
case full of gasoline diluted oil. Is it a small possibility (?) - yes, but
very, very small.
As it has been pointed out the gas would have likely leaked out the
carburetor and been noticeable on the ground. If per chance fuel had
actually leaked into the engine it likely would not have started either
because it was hydro-locked or been ridiculously rich. In any of the cases
the smell of gas would have been noticeable.
If the cam bearing was noticeable bad, what was the condition of the other
bearing and for that matter the cam itself? To find that out the engine had
to be opened up. If only the cam bearing is bad it seems to indicate
improper installation. That being either the bearing was misaligned (though
getting the cam in would have made that noticeable) OR more likely the oil
hole was not aligned with the galley. I would press the matter before
accepting it as "your" problem.
