Wrong way to end a track day

Jul 7, 2009 update on robench's 1992 Ford Mustang LX 5.0

Broke some sort of internal engine component during the last session of a PIR track day.

When down shifting from 4th to 3rd at the end of the back straight, a strange rattling noise started and there was a huge loss of power. I conveniently coasted out the pit exit and the engine immediately died when I pushed in the clutch.

It still cranks over, but it won’t start. The compression sounds wrong when cranking, and the distributor still turns, but doesn’t point anywhere near #1 cylilnder at TDC, so it’s something serious with the timing system. It’s really not clear exactly what happened. I’ll be tearing into it tonight to see what sorts of expensive damage I can find.

There goes my budget for this season. The towing bill from Portland to Seattle was bad enough. We’ll see what repairs cost with 16 potentially bent valves and whatever other damage there is.

I’ll add the juicy broken part pics once I have some.

On a good note, the car was running/handling phenomenally well for a old Mustang up until disaster struck. It really is a fun track car when it runs.
