I had responded to a recent request from Rolando Benitez, who had
asked me about some problems with low oil pressure on this TR6 after
the car is warmed up. I had asked him for more information.
After receiving this additional info from Rolando (rbenitez@c.net.gt),
I'm stumped, so I'm forwarding the message on to the triumphs list
(triumphs@autox.team.net) in hopes that some of those that have
engine rebuild experience may have some suggestions.
Please include Rolando in responses, as he may not yet be on the
Triumphs mailing list.
