Hello, ive recently fitted another head on my clio. I timed it up using the special tools require for the cams and crank. The car runs ok but it misfires on tick over. Sometimes the car is slow but most of the time it pulls well and you can feel the vvt coming in at around 4k. Also recently after using it a while its developed a whine (like a supercharger noise) through all the rev range. upon start up you have to rev it to get it whining but then it stays. Ive checked for air leaks and there is none. i believe it must be the dephaser pully not being set correctly. I didnt set it as i could see how to (should of found out!!) Can anyone tell me how to do this please or have an idea whats causing the problems?Thankyou
