What a bunch of idiots! Not like me. Well......ok.
#1.Rebuilt engine in Ford Falcon after hearing a big rap. Reinstalled engine and "rap, rap,rap". Put in the clutch and gone. It was the tranny.
#2. Had dealer rebuild engine in old motorcycle (I won't bother you with the details and heartaches of that) only to find out it was the choke on.
#3. Today, overtightened valve adjustment on my 300tdt thinking I was going the right way and broke the valve stem. Dropped valve into engine.
Grrrrrrrrrrr
