So my engine noise is more or less the crank pulley slipping so needs changed.

 

What does everyone recomend ?

 

Stick with the oem and get a new crank damper pulley or get an alluminum pulley from the likes of japseed

I'd prefer not to hear any excess noise and also avoid having to buy new belts too.

Oem: same belts and can adjust timing with a timing light

 

Lightened: new belts as different size and no timing marks, but unless everything else in the crank line or belts is lightened, then any gain wont be noticeable

ok,

 

So need to find a new or excellent condition oem crank pulley.

Any idea on costs for a new one ?

They look to be about $300 new mate

A good second hand one would work well as most engines have not done a lot of miles.

Is it the actual crank pulley at fault or the woodruff key that holds it in?

Ditto...

No idea to be honest.

 

Whatever is making the banging noise on high revs i guess.
