Have not had any problems with unleaded on my car, and it's now on 193,000miles. Save your money for something else. |

I thought later A series were always fine with unleaded anyway as unleaded was common before the end of production? I certainly haven't worried about it. |

Ally heads need valve seat inserts. Cast iron heads often didn't have valve seat inserts, because the lead provided the protection. Remove the lead, and you're left with a relatively soft seat, which suffers from recession. The official line from Citroen was that all engines from number <whatever> were OK - but AIUI the suspicion's always been that that was just the number of the engine they tested, since the part number for the head didn't change. |

Hi Reason for asking was, in this warmer weather, my engine won’t fire up straight away when the engine is hot – takes a couple of goes. A friend suggested that it might be because the exhaust valves aren’t quite doing what they’re supposed to, so a teaspoon of Castrol Valvemaster into a full tank would “make all the difference”……not sure it’s made any, to be honest…..but – will it harm the valves??? Seats???? And is the hot starting problem just one of those twin pot nuances??? Thanks all Will |

I've also been told it depends how you give it throttle on startup - foot to the floor, then turn the key and back off the throttle when it kicks in is a tip I've been told. |
