Hi there I've completely converted a 3i to a rs and now I've got the engine running cylinder 1 sounds like it's tapping also if you hold the ht for cylinder 1 you can feel it tapping yet all the others are smooth, do you think it could be a dry tappet ? Also now the car is running it won't start from cold and takes about 6 turns of the key then it's a little lumpy for bout 10 secs then it's fine, I've unplugged the cold start and no change, would be greatfull for any help cheers Ryan
