MGA MGA---KaBoom!

The blue 1600 MGA (below) belongs to my friend and fellow racer, John F.
It suffered one of the most catastrophic engione failures I've ever seen. This was at our Watkins Glen event last weekend. When the engine seized (due to one of the front rods failing) the crank bent in the middle, blowing out both front sides of the block in the process. After they towed it in, I noticed the dipstick was hanging at a funny angle. When we pulled up on it, a piece of the block weighing about 5 lbs came with it.

The second and third picture show some of the block damage.

I actually caught the engine failure on camera (he had just passed me when it failed). If you click on the video (at bottom), and slide to about 1:20 and watch, you'll see it.....followed by a view from his in-car camera of the failure.

John just sent me a note in which he says:

"The centre main is still attached to the crank but no longer to the engine. Part of the torque reaction of the sudden stoppage was absorbed by the bell housing which reacted by cracking all the way around!"

John's a good-natuerd Brit and he simply laughed it off. He'll have it put right by next race season.

Um......not an engine expert or anything but I'm PRETTY sure THAT is NOT going to buff out.... :smile:

Sounds like he has a sense of humor. If you see him during the off season, make up a small box and write "Illudium Q-38 Space Modulator" on the cover and hand it to him, saying, "They fixed the Ka-BOOM problem after the Q-36 model." :smile:
 
Follows right along with the old adage about your first indication of a blown engine at speed is when you spin in your own oil, nearly simultaneously to the sound.
 
That's why you never use the weak 1500/1600 crankshaft! I have also done that!
