KV6 Oil pickup O-Ring ?

[Mgaz]

My ZT190 always sounds noisy when first started from cold. Its an 02 plate and I've seen from reading threads on here that I might need a new oil pick up O-ring in the sump.

ITEM: O Ring - LYX000210L https://rimmerbros.com/Item--i-LYX000210L

I don't know for certain if this will cure the problem but I'm willing to give it a shot.

Is it easy enough to remove the sump and replace the O-ring?

Also, it looks as though there isn't a sump gasket on the KV6, rather some sealant instead? .

Looking at rimmers prices, that seems excessively expensive https://rimmerbros.com/Item--i-LVV005188

Is there an inexpensive alternative?
