I have driven in the last 36 hours 360 miles in my 1973 Transit V4 1.7 Cologne 130 ex German Fire Engine.
This is the first great adventure in my fire truck after 2 years of ownership, mostly driving no more than 14 miles in one time.
I left my wife at home, as I knew this would be an adventure and did not want a scary wife when something goes wrong. I stayed at 50 MPH using backroads across Minnesota.
I stopped every 2 hours to check the oil and coolant levels, to sure make everything was good.
At the 361st mile, just 40 miles from home, all of the sudden, I head a pop, the oil pressure warning light came on, and so I pulled over immediately.
I checked the oil and the oil level was good, I checked the coolant and had to put 2 pints of coolant in after letting it cool down. I had been keeping an eye on the temperature gauge for the whole journey, but cannot remember looking in the minutes up to oil warning light coming on.
I started it again, and oil pressure light was still on, it was running 3 out 4 cylinders, moved the vehicle to a more safer position on the road about 300 yards.
There is no knocking or worrying sounds coming from the engine.
Let it cool down again, checked the coolant and another 2 pints of coolant.
I checked radiator, coolant hoses, oil etc and it looks like coolant had been coming out of the overflow.
I realized no point moving any further and called a tow truck for the last 40 miles home, so not to cause any more damage.
I am hoping it could be a head gasket failure, radiator cap failure, but suspect is could be a lot worse....
Any recommendations on how to determine what is wrong or what common problems to look for?
Any thoughts or recommendation based on experience would be appreciated.
