it. Every time I started the car the engine let out a
cloud of smoke. During each gear change, same thing.
Thinking the problem was with the valve guides and
wear in the engine I rebuilt the whole thing. Now, I'm
convinced the problem was with the external oil feed.
I removed it. A machine shop owner told me that the
amount of oil flowing to the head was too much.
Again, one man's opinion.

Hi Jim,
(I was just thinking about you!, that's too wierd).
In answer to the above question:
I have three of those oil feed hoses lying at the back of my garage.
Guess why?
A) too much oil in tappet cover,
B) noticable drop in oil pressure after fitting,
C) Smoke from previously clean exhaust.
and yes, I even had a restrictor made to cut down the oil flow to some degree.
It didn't help a great deal.
In my experience, they are a total waste of money.
In the words of the song:
"So you've got an oil feed hose, that don't impress me much!"
And yes I have tried them on both four and six cylinder engines, both new and
old.
Never had an oil leak as described by Jonmac though!
And as for the TRX's and the Fury for sale...
I work in the building which faces Olympia across the street.
I read today (Tuesday 7th December) in Triumph World magazine that they were
being auctioned, yesterday (Monday 6th December)!
Heck, and there I was wondering what to do with all that excess money and car
storage space!!!
Ah well.
(note the Bristol car showroom is almost next door!, hmmm...nah, too ugly!)
