[Supras] Interesting problem...

[Rich Peacock]

I was toying with a motorcycle a few weeks back with my 87T and after 
shifting to 2nd gear I smelled coolant so I shut the engine down and 
coasted to a parking spot, and had the car flatbed to my work.  I 
inspected the car today and instead of just having a hose pop off / 
break like I expected, I've actually popped a freeze plug!!!  It's the 
front most DS plug.  I run a 13lbs. coolant cap and have had no cooling 
problems with the car in terms of overheating.  The motor has 20,000 
miles on it and is running 425+RWHP.  Luckly, I don't have an AC 
compressor, so it'll be relatively easy to replace. 

Why would a freeze plug "just come out"?  I've never seen such a thing.
