I recently was racing and missed a gear and redlined pretty good. good enough to make my car idle like its about to stall and my valves are clicking louder than usual. So i took it in to a local repair shop to get my valves adjusted and timing and idle set. . . first they said the problem was a failed #3 injector then replacing the injector wasnt the problem so they did a leakdown test on the #3 piston and found out it only had 135 psi of compression. now they are leaning towards a crack in my head. . .anyone have any input on what i did to my motor? any input would be helpful.

 

bent valves. did they do a leakdown ot just compression test?

my guess is a bent valve.
