"What's that sound"!?

[AlCan]

Hi Guys,

Asking this question reminded me of an old song. It's actually called "For What It's Worth" - it's a truly timeless classic. All the old timers will remember it, and it seems to me just as relevant now as then. When they knew how to create great music (if not such great cars.)

Anyway, FWIW, I recorded the (overnight) cold start sound of the troubled (almost) teenager - the 2013 I've discussed here at great length. I'm sure the experienced mechanics here will recognise this sound immediately. I suspect it's Big Ends, but would love a more experienced ear's take.

As you'll hear, there are four distinct sounds: Starter Motor, a couple or so deep, well-fueled diesel combustions, followed by a few sharp rattling sounds which quickly go away. Those are the sounds I'm interested in.

Then, for most of the rest of the recording, at a much lower volume, you'll hear the notorious Cam Chain Rattle which also fades away near the end.

I'd love your comments on this, as my Oil Pressure fittings apparently caught the slow boat from China.

Assuming this is big ends, question is, How Bad?
