so another update if anyone is watching, i fixed the vacuum leak at the pcv, started the car rattle was there but faint, loads of white smoke but not caused by coolant its at the maximum, car at standstill will not hold rpm between 2000 and 3000 rpm if i just stab the throttle it reve up freely. from 3000 rpm on the rattle is not there at stand still. it is there up to about 4-5000 rpm and dissapears after that.
under load its there but sound different. tried un plugging the iacv but the car ran like a pig. there still seems to b a vacuum leak someware in the fpr throttle body area. if i disconnect the vac pipe to the fuel pressure reg it makes no difference should it? iv also put injector cleaner into the fuel
