Odd Timing Chain Slack

Last time at the track, the race car blew the head gasket. It's a 240Z with a 280ZX turbo motor.

 

Today I finally had a chance to start taking it apart to replace the gasket. Went to put the chain tensioner tool in to prevent the tensioner from popping out and it would not go in at all. When I looked closer, the spark plug side has got good tension, which you would expect with the tensioner on that side. The chain on the manifold side is very loose.

 

The last time I pulled a head (different car)the tensioner tool slid in easily. Now I can't even force it in between the chain. Anyone have ideas on what would have caused this? Any suggestion on what to do next? I really don't want to pull the front cover if I don't have to.

 

Thanks,

 

Marty
