You usually get a bit of a rattle on start up but hold the revs around the 3-3.5k mark with the bonnet open and you will hear a constant knock knock as if one of the rods are loose on the crank side this is usually bearing faliure

I find it's most noticeable at 2500 RPM. If you film the noise & post it someone will tell you if it's big end failure.

Start it let It warm a little then sit in car and start to rev very slightly and let foot right off you'll hear a knock just as revs drop. Get oil pressure guage fitted as that will tell you alot

That one above is well and truly borked. But a more minor one maybe more intermittant and only do it when revving or at certain revs

Another one ready to shoot a rod out the block:

Oops !

And the moral is: Don't rag it or it'll die. Engine probably saved his gearbox and diffs from dieing though
