I drove the Dog from berden to Gedney this morning. Left at 03:30 to dodge the traffic. 8 miles in and the headlights went dim, the cab filled with smoke - looking at the engine cowling I could see a bright orange Glow THE DOG WAS ON FIRE.
Now I know why we carry fire extinguishers!
I lifted the cowling an inch and gave it a blast - fire extinguished.
Now to assess the damage
My brand new alternator positive lead was charred and burned out, I couldn't work out why. There was also a puddle of oil, but it was under the fuel pump side which never leaks oil. But directly under the fire damage
Grabbing my fettling kit and head torch I rewired the alternator and went for a start.
The engine started immediately, good volts so the alternator was fine.
I looked back in the engine bay and to my horror could see a jet of oil spraying out all over my new wiring.
There was a pinhole in the capillary tube that goes from the engine block to the oil pressure gauge.
It looks like this jet of oil was the cause of the fire, igniting off the exhaust. Luckily I had something in the toy box to blank it
I went for it and continued my journey. Managed to complete the rest of the journey without incident ( cherry bomb makes a definite difference) having no oil pressure gauge gave me one less thing to worry about but I did stil get the oil warning light at very low revs
But the dog is re-homed - now to clean up the dry powder I which incidently is brilliant for highlighting weeps and leaks
The Dog is home....
