My engine might be on it's last leg...

A few days ago I noticed an odd metal on metal noise when shutting off the engine. It only lasts the short time it takes the engine to wind down to a full stop.

The sound is not present (or at the very least not audible) when the engine is on. It's a very quiet exhaust, stock internals and exhaust with RB cat-back.

I suppose the only three possible culprits are: engine, clutch mechanism or the transmission.

I will do a compression check ASAP but the engine is behaving just fine. I say this knowing if it turns out to be the engine, it will get worse quickly.

Thoughts?

 

Spun bearing? You are at 250k, maybe someone forgot a couple of oil changes.

 

I'll do my research on that.

Anything else come to mind? Anyone?

 

You could also check your flywheel, though I doubt that's the problem. My Brother-in-Laws flywheel had turned itself loose somehow.

Cheers,
Cody
