KLINGERIT CYLINDER HEAD GASKET

Owing to a sticking exhaust valve, we recently had to remove the Cylinder head from 27.G.VI. after a mileage of 10,160.

We experienced considerable difficulty in doing so, due to adhesion of the Klingerit gasket. We make no provision for levering a "stuck" cylinder head.

We have not experienced this trouble before, but have not run more than 5,000 miles at a time before removing the cylinder head.

A copper asbestos gasket was used when replacing the head, as a Klingerit gasket was not available.

We will take an early opportunity of fitting a new Klingerit washer with the joint faces oiled. This material makes an excellent joint, and is considerably cheaper than the C & A type.

No difficulty experienced in the Garage. we should take hold of the exhaust & inlet manifolds for leverage
Guy's Self changes the head several times in France on R-13-5 without difficulty using Klingerit gasket.
S.P.O was still running like this when Prof/FD{Frank Dodd - Bodies} was left.
