Re: Mayhems 71 Nova
No problems found. We think the bolts on the intake were not torqued correctly and they vibrated loose, allowing coolant to leak around into the valves/cylinder. This likely occurred during or after a weekend of running it down the track 8-9 times. There was no signs or sounds of trouble, until it fowled the plug while filling that cylinder with coolant.
Putting it back together now, flushing the oil, etc.
Will find out for sure over the weekend.
