Calling me a liar is simply no answer at all.
The operator involved is well known on the central coast and has been known to use auto brake fluid, auto start solenoids and such like.
A shining example of owner/operator maintenance.
An exhaust valve leak on a compression test is investigated further prior to the cylinder being condemned. Staking the valve and even a further ground run is part ov the process. Once the cylinder is removed a check with kero is carried out. Once confirmed the valve is removed and inspected.
Commercial imperatives of the operator are not high on the list of considerations for commercial operations.
God Bless on this holy weekend
