[DeTomaso] BBORR engine failure

[Will Kooiman]

Trust me.  MF has bad gas.

For what it's worth, I didn't hear a single bang when my car came apart last
year.  The piston (cast original) was demolished, there were 3 large windows
in the #3 cylinder, the cam was in 4 pieces, the intake valve head was
jammed into the camshaft, and 2 lifters were in the oil pan.

It was running great, but I suddenly lost power.  I looked in the mirror and
saw clear liquid spraying all over the place.  I thought I lost a fuel line.
When we stopped, I could see it was water, so I figured I lost a radiator
hose.  It wasn't until I saw piston bits that I realized what happened.

My hearing isn't that bad.

My point is that just because MF didn't hear an explosion, that doesn't mean
there isn't internal damage.  Hopefully it's something pretty easy to fix,
though.

With all due seriousness... if Will is correct, consider this.  If the  
rear cam plug came out, where does it go?  Between the block and the  
flywheel, it turns, gets caught and BANG, gets twisted into a pretzel,  
gets caught again and BANG, eventually falling to the bottom of the  
bell housing.

The whole timing thing still has me bugged though.  I think you may  
have got some bad gas as you were suspecting, but I'm anxious to see  
the forensic results.  Take lots of pictures.
