[Healeys] Pressure relief valve

[Oudesluys]

If in good condition I would not worry about is. Failure of this kind is 
mainly caused by lack of servicing i.e. old and dirty oil, blocked oil 
filter, not enough oil supply because of blocked passages etc. in fact 
when it is already (partly) worn.
If you are worried it is a simple job to reduce the pressure to 50-60 psi.
