hello guys, Like tittle say a crankshaft woodruff can bend.

The car was running perfect and suddenly start to act like the time was retard. Put the crank pulley to TDC and the EX. cam was 1/2 tooth retard, if I put the cams to line the marks the crank is off, but not one tooth.

This happen after solve my problem with the AEM FPR (this thing is S***). I hook my laptop and went to clean the program, after few pulls the car start to sound like time retarded and found this in the time.

Any help will be appreciated.

 

solved, why check the middle cam timing marks but not the cam pulleys, the exhaust pulley slip a few degrees.
