Crank pully sanity check...

[21TonyK]

"My" common sense says this is knackered. The cracking means the pully has slight movement when you press it and it rattles a bit.

If I'm wrong and its cosmetic tell me before I order a new pully and belt....

I'm not familiar with that engine, but that would concern me too.

I'd be changing that.

Another pulley for comparison, also well used but nowhere near the amount of crackage, https://www.ebay.co.uk/itm/135318227597

Yep that’s fooked, at some point it will depart the car. Change the belt, pulley and crank bolt. Corteco do a kit.

Yep very common repair on that engine and that needs doing now before it totally de laminates if the dealer part too expensive Corteco are an OEM quality brand and cheaper than dealer parts , probably pop in a new front seal while your in there no special tools required to change either
