[Healeys] Oil Pressure

[Michael Salter]

Good question Roger.
Amazingly the crank journals had some oil residue burned onto them which
easily polished off. This was a nitrided crank.
The shells themselves definitely were also in "do not reuse" condition with
burned oil on the surfaces but when checked with "Plastigage" were still
within spec.
Sure blew me away!!
