I've seen this happen once before on a friend's car. The guides were chewed up pretty good. If I were you, I'd make sure to take off the chain case cover and inspect all the guides & sprockets the chain rides on.
we thought the same as well^ that sounds the MOST logical. since the tensioner holds that guide into place, i can imagine it slacked perhaps aenough to allow it to slip off the guide. No disassembly yet, but hopefully it wil be an obvious failure
My buddy and I recently got an 04 k24a4 from someone b/c it "lost oil pressure". When we took it apart, the chain was so loose around the sprockets that we could take it off without touching the tensioner. Motor was 100% bone stock.
Just prior to this happening the original owner of the engine took his car to the Honda dealership to fix the timing cover which was apparently leaking oil. My theory is that they tried to install the timing chain on the k24 like they would have on a k20 and messed everything up.
That's strange though. Other than the fact that the guides were fine on our motor, our chain looked almost exactly that loose when we took it apart.
