G'day Magnus
Many years back I had exactly the same problem with a freshly restored 100
engine.
I changed the pressure release valve and spring - Fixed.

Subject: [Healeys] Oil pressure
I have a problem with an engine that I just restored completely. The oil
ressure gets too high when revved over 2500. The pressure reaches all the
way p too 80 psi, which of course is way too much. The strange thing is when
the ngine is cold and you rev it, the pressure will not rise above 60 psi.
Quite ontrary to the normal behavior. The oil pump is a new Denis Welch
unit, the il pressure release valve and spring are new, all bearings in the
engine are ew, all parts have been machined to the right tolerances. I4ve
tried with a sed release valve and spring that is quite softer than the new
one. Resulting n the same high pressure.
This has got me quite puzzled and I ran out of ideas on how to solve this.
Has
nyone experienced the same symptoms and did you find a working solution? I4m
esperate for good advise!
