Car Forum / MINI / August 2005Conversion for unleaded
Can I convert a 1986 Mayfair from LRP to unleaded, The car has No Cat 998cc and if so....How? Unfortunatly the only real way to do this is have the valve seats replaced, any good machine shop should be able to quote for the work on the head, alternativly buy a lead free head from one of the many shops in Mini World or Mini Magazine. Thanks Karl > Can I convert a 1986 Mayfair from LRP to unleaded, The car has No Cat > 998cc and if so....How?

You are going to get the valve seats replaced or buy a head which is known to be an unleaded head (seats replaced) and thats either new or second hand. You can not tell by sight if they are unleaded seats. > Is there any way to tell from the colour of the heat outside if it has been > converted [quoted text clipped - 8 lines] >>>Can I convert a 1986 Mayfair from LRP to unleaded, The car has No Cat >>>998cc and if so....How? Have you tryed Castrol's octane booster and valve seat protection product? You might want to give that a go, I know people who have used it with no problem with super plus for MGB's. Having the valve seats replaced can if you have it done properly by people who actually know what they are doing be rather expensive. This product only costs about 12 quid. > Have you tryed Castrol's octane booster and valve seat protection product? > You might want to give that a go, I know people who have used it with no > problem with super plus for MGB's.

Sticking oily type stuff into the tank is for days of old! It's like two stroke pre mix - dont forget to shake the tank! Getting the valve seats done is the way to go. Why should you have to pay the premium of super unleaded and however much the bottled gear is just to run an old car? Getting the valves done would pay for itself the more miles you do - so do it and get out there!

I agree. Or even better, don't change a thing and only get a new head or fit new valve seats IF you start having worn valve seats. If the engine is old enough to not not have hardened valve seats, it's probably old enough to die of old age before you even have to worry about worn valve seats. I think that may well be a better option. Certainly with Rover SD1's people worried an enourmous amount about wear, only to remember that the car was designed to be exported to the U.S, thus it was designed to run on unleaded anyway. This may well be the case with your engine. > Can I convert a 1986 Mayfair from LRP to unleaded, The car has No Cat > 998cc and if so....How? I have just swapped out an unleaded 998auto for a 1275 VP auto. You can have the 998cc unleaded cyl head for £30, I would advise that it's skimmed though as the head gasket had gone. karen DOT christiaan AT btinternet DOT com |
