Timing belt skipped 5 teeth - how?
 

First time posting - hope I'm doing it right.
A couple of weeks ago I started my '95 Accord EX with vtec engine. It always fires right up and this time was no exception, except that it also immediately died and would not even try to restart. After troubleshooting the fuel system that didn't seem like the problem and I had good clean spark. So.... I thought exhaust obstruction or mechanical timing. Started with mechanical timing and sure enough after pulling the valve cover and setting the belt pulley to tdc on the #1 piston it was very obvious that the mechanical timing was way off. I decided to take it to my mechanic (who's great) who had installed a timing belt kit 10,000 miles ago. He dug into it and sure enough the belt had skipped 5 teeth. The weird thing is that there was no clear cause for the belt to slip. Everything was intact, functional and operating as it should. The belt had no damage and was in great shape. He reset the belt and it runs as it always has.
Bottom line is my mechanic, his partner and me are completely stumped as to how this could happen.
Anyone have any ideas? Thanks.

Did they put a new tensioner and spring on when they did the belt 10K ago?

It is possible to install the tensioner incorrectly. See following DIY post.

This leads to a loose belt which increases chances of slippage of belt.

good luck

Thanks for the replies everybody, much appreciated. And much thanks for the link Texas Honda, great info there.

I agree that it's likely tensioner related and will dig into it when I get a chance. Thanks again.
