Valve Springs
We are assembling a cylinder
head for a customer with a TR-4 engined Morgan +4. We had to replace
the valve springs. The new springs which we got from Moss Motors
only give 60# of pressure with valves on the seat at the correct
installed height. If you don't have 80 to 85# on the seat, I know
from experience that the exhaust valves will burn in about 12,000
miles. TRF is out of stock. I don't know about Victoria British,
I suppose we will try them next. Racing springs are 50% stronger
and will work, but I feel that they will accelerated wear because
of the added loading. Every time we complain to Moss their reaction
is always that "we don't get complaints from anyone but you" or
people don't drive their cars enough miles for it to make any
difference" The only way we are going to start getting consistently
go quality parts is to complain loud, clear and often, whenever
it is warranted.
