[Healeys] Bn2 excessive oil pressure

[Oudesluys]

The main cause is probably the earlier FRAM oil filter being of poor 
quality and having a rather high resistance.
That said, 90 psi is very high so is this K&N filter OK and did you try 
another?
However I do not think it will cause any harm. For normal use ca. 
50-60psi at 2500rpm and a hot engine should be fine in most UK engines, 
in race applications it could be higher.
Also, check the accuracy of the oil gauge!
