I recently pumped 10 gallons of diesel into my truck which has a 14 gallon tank. It had 4 gallons of gas at the time. The fault lies with the distributor who accidently filled the store's unleaded tank with diesel. A large number of customers were affected.
Anyway, I was able to drive my truck about 100 miles making it home in the middle of the night.
The next morning, my truck wouldn't start. Thinking the problem was with the fuel pump, I began removing it. On my truck, the fuel pump extends into the crankcase. After removing the top of the crankcase, I found two rocker arms completely broken off from where they were supposed to be attached. I don't know engine terminology so I dont know the name of the part that they are supposed to be attached to.
The point is something happened when I drove my truck home that night. I heard some clanking noises as I drove and should have stopped but I wanted to get home since it was late at night and I live out in the middle of nowhere.
I've asked a few mechanics if the damage I found was a result of the diesel. Some have said "no" and some have said "yes". What do you alll think?
Did the diesel cause the damage to the rocker arms or is it pure coincidence that they broke the night I put diesel in my tank?
My truck is a 4 cylinder engine. It has 323,000 plus miles on it.
Any comments or questions would be appreciated.
