My engine has done 56k genuine miles, now here's the question...
Do I get the 998cc engine block changed from leaded to unleaded or buy a 'new' refurbished engine which has already had the conversion/painting/ fault finding(?) already done?
Price for the latter on Ebay is about the same as the former

Another question, does a refurbished engine reset the clock or does it carry it's existing mileage pre-refurbishment?

Be very careful buying off eBay. Do a search on here; there are a lot of horror stories.

Is there anything wrong with the engine as it is? 

 

It's the head that is leaded or unleaded.

Nothing wrong with the current engine whatsoever to be honest, it's just not been converted yet.
It really runs well on unleaded (and additive)

Edit: to clarify, when I said 'block' I meant engine as a whole unit x

If by some chance you consider buying off eBay put the details on here because quite a few of the rip off merchants are known to the members.

If it ain't broke, don't fix it.

I would say if the engine is in good heath then leave it as it is and use additive if you want. Personally I don't use the stuff in any of my classics as they don't get thrashed (often) and don't do a lot of miles.

Good point well made! 😀
I'll stick with the original plan rather than try and cut corners *thumbs up*

Exactly, and they keep changing identities as well.

It's only the head that needs hardened exhaust valve seats fitted, no need to replace the engine if there's nothing wrong with it.
Alternatively just use an unleaded fuel additive like castrol valve master or similar.
As mentioned above, beware of some of the ebay rebuilt engine scams.

They're all out there waiting to take your money from you, you're doing the right thing by asking on here first.
