Hi, Chip. Although not the greatest situation, I believe this is a function
of the canister oil filter system on Triumphs. I believe the Spitfire set-up
is the same for the TR6: when shut off, all the oil drains away from the
filter and back into the sump; on start-up, the oil pump must first refill
the canister & filter before the oil pressurizes and works its way back
'upstairs', hence the 2 second delay. A spin-on adapter helps solve that
because the oil remains in the filter element, thus providing more
instantaneous feed to where the oil needs to be --the valve head. After a
few days, there is still enough surface oil to protect on initial start-up;
after a few weeks or months, not so much - removing the rocker cover and
oiling down the assembly has been recommended in various 'tips' for winter
storage, etc. Cheers, JD

Subject: Spit Oil Pan Question
Listees and Listettes:
There is a short pause in oil pressure build up when I start the
Spit after
it sets for a few days. Some slight bearing noise but all is well
after
about 2 seconds and oil pressure stays good throughout all temps
(10W-40 -
with 20W-50 it's more like 3 to 4 seconds).
The oil pan has been crushed by POs supporting the engine
incorrectly whilst
replacing/removing the transmission. Is the oil pan pickup close
enough to
the bottom of the sump that it might be partially restricted by the
crunched
pan metal? I thought about dropping the pan, cleaning the pump
screen and
perhaps buying a new pan but it seems that Spit Oil Pans aren't
catalog items
with the regular suppliers....Moss, Spibits, etc.
If my theory is no good, I can live with the "bearing noise" and
I'll leave
the pan in place....
Thanks,
Chip Krout
