A local body shop called and asked for an estimate to have a timing belt replaced on a 2005 Elantra, that was six weeks ago. They claimed that the car was hard to start unless they unplugged the VCT solenoid. The PCM would constantly set a P0016 code for crankshaft / camshaft correlation error.

The owner reported that "he had talked to this person, and to that person" and they all said the belt was out of time. That's why he wanted a price on resetting it a while ago. He also pointed out the fact that the dealer had done the belt less than 5000 miles ago. So all he wanted was for it to be re-timed, if it needed more than that he was just going to send it to the auction.

Now a couple years ago, pulling this apart and going for the check of the belt timing and subsequent adjustment would have seemed routine. Today, there's no way that I'm not going to pull a waveform off of this before I pull it apart.

So, here it is...

Lets add some cursors to see exhaust BDC and TDC.

Yep, that's out of time. Let's tear it apart.

Hmmm.
