Hi,

I replaced the engine casing section that houses the clutch cable and cannot stop a coolant leak. It's coming from a small hole right beside the coolant drain bolt.
It's a minor leak but still a leak.
Has any one had this issues and how did you fix it?

Cheers

I think your waterpump seal is gone

Agreed. Remove the primary drive cover after draining the cooling system and strip the water pump, thoroughly inspect the ceramic ring in the impeller and the carbon ring in the stationary part of the seal. There's probably either a crack in the ceramic ring or the carbon ring is damaged, more likely the latter, meaning the seal assembly will have to be replaced.

Thank you for the advise folks, side of the engine off again this weekend lol

Ah the joys!

Thanks.
