Getting towards fire danger season, a couple of weeks ago, I started working on our firebreaks. A nasty noisy and a nasty smell from ‘Fergus’ the tractor told me that something was amiss. Symptoms pointed towards a blown head gasket; all prepared to replace this, I removed the rocker box cover and was disturbed to find a valve missing. A spring had failed, the valve had dropped, smashed the rising piston and fractured the cylinder liner. That’s as far as I know at the moment – Fergus went on an ambulance today and was admitted to the G & J East Hospital for Sick Tractors.
For those who aren’t squeamish and don’t mind the sight of oil, I have taken pictures.
Fergus taken away by ambulance.
