i think they have, would this have allowed the car to start originally though because it was running with no problems for 10 mins, thanks for replying. the engine was taken out and then refitted, no mods have been done this time apart from a new clutch, this has been a 2 year project and i want the car on the road for feb if poss. the mechanic does all the work on my company vans so he is not a specialised rs mechanic but he knows his stuff
