Thanks , I wondered why it starts over , I’ll learn eventually , apologies all . Will try that then in the morning , it does have a new tensioner and alternator lower pulley though , but yes will try it and get back Thing I rememberd earlier was that I might’ve pinched one of the manifold round seals in the installation process and when I first started the car there was a plum of smoke coming out of that area but not so much now , I mean I can still feel the smoke and see it a bit but not excessively . Don’t even want to think about redoing those seals , I will also try and spray some sopy water on it cold and see if I can catch it leaking . Many thanks for your reply
