hi andy .well done great result ,,,, I had same problem 18 months ago ,,I have exact same car, same year with lpg zavoli multipoint.... sent engine off to wards of rugby ,complete rebuild with top hat liners ,, no problems but not cheap !!!!!! but that's the joy of owning a p38 ????? ,,now all good ,, just wondering about what you said about cleaning reducer / vapouriser on lpg system ,,,, although I have the lpg system serviced every year as of the engine serviced separately . would the service of the lpg include the cleaning and checking of said reducer/ vapouriser ????? if not where is this so I can clean it myself ,,,,as I never actually got to bottom of my problem as to why my engine went in first place !!!!!!!! all know was that one of the liners no 6 I think had gone due to overheat ,,, would welcome your answer re reducer/ vapourisor or a photo would be great if possible ,,,,kind regards and best of luck with the future ,,,Mozz
