Bob,
I'm running the same plumbing arrangement. I built an over ride to the
electric valve that controls the sump
so I can manually control the oil sump when I want to. It's really odd that #
3 was the only cylinder affected.
Whatever it was took out the piston too, maybe the liner as well.
I may try my spare crank this time. I just wonder if there is something in the
crank oil passages that
just won't flush out.

Do you have the accusump plumbing routed properly? Could the pressure be
bumping up against the pump flow, an inline check valve or a remote filter? I
have it plumbed to dump into the center of the oil galley. I drilled out the
plug to take an AN8 or AN10/pipe thread adapter. Between that and normal oil
passageway problems it should be fine. I've been running wet liners since 1996
and haven't struggled with oiling issues.

Jim: Are we talking a TR2-4 motor, Spit motor, or TR6 motor?

I'm not sureB what caused it. IB was on my secondB race on the engine. It only
affected # 3.
I can only surmise a contaminant lodged in an oil passage. The oil was changed
after an hour
of break in and again after 3 hours and again right after the first race. New
filters every time.
This isn't the first time Iv'e toasted a low end because of oiling problems.
Ran perfectly during and after the first race, through practice and quali. on
the second race.
Three laps into the second race it gave up.
I have a new oil pump and blew the crank out real good before assembly.
I took great care in keeping things clean.
Since using the Castrol my oil pressure starts out at 80 plus psi but by the
end of the race drops
below 50. Goes right back up after it cools. I also have an oil sump that
kicks in at 25 psi.
IBB B welded in a windage tray after the last time.
These little tractor motors are a bit of a puzzle.

Jim,
What caused the bearing failure? Oil pressure drop? Misalignment?

Betreff: [Fot] Spun a d#@n bearing
Greetings FoT
I spun my # 3 rod bearing last weekend and my crank is already at .040
under.
It turned the rod blue so it's toast. I know it's been discussed before but
I think
it may be time to weld the crank and go to Chevy rods.
Any advice for the conversion ?
Again, thankfull for your advice,
Jim G.
