Rod knock on a (brand new Crawford built) Subaru motor. I had never actually heard it before but here's a pretty good clip revealing it.

A while back my brother had a 99 2.5 RS throw a rod that thing sounded way worse than that:mrgreen:

Ouch, that sounds awful. I can't believe that's on a brand new Crawford block, if I were the owner I'd be fuming.

Here's another example: http://www.zippyvideos.com/3386998586271116/dscn1138/
That happened on a Stage 2 WRX, over-rev apparently. Someone said the first bit of clicking is when the oil isn't getting to the bearings right after startup. Not as good of an example as that Crawford engine but still.

My first car threw a rod (87 sentra) and I drove it like that for a week because I had just filled the tank before the rod went lol.

This is why you build engines yourself.

Had rod knock due to oil loss and spun bearings before, but then I have also threw a rod.

sounds like my dads old 95 RHD Legacy with 195k on it. Thats not how they're supposed to sounds? lol

Im toying with the notion of a RHD 95 legacy STi swap. But cant make up my mind.
