Message: <blockquote data-quote="upontheriversky" data-source="post: 1063656317" data-attributes="member: 59480">hi all,i have recently full overhauled 1.0 kelisa engine and couple of problems rose:- rough idling, almost rougher than before overhaul but idling rpm is normal. i did full engine balancing with new oversized piston- whistling noise coming from throttle body/manifold area or belt pulleys area- louder tappet noise even with fully syn oil with torco mpz- white smoke on cold startup in morning, disappear after warm up but ive replaced valve seals, head gasket, almost every seals and piston rings- popping noise sometimes still occur when accel/ decel- some light oil vapor condensed on new valve cover vent tube going to manifold here is video ive recorded, please note the sound of blowing through a bottle is actually my air filter, whsitling noise is higher pitch:<a href="http://www.youtube.com/watch?v=lOIphFNDrJA" target="_blank">whistling and tappet noise - YouTube</a>here is the thing, the mechanic installed an extra fuel filter before the fuel rail, he convinced me it would filter the carbon produced by the pump as ori filter is located underneath so it filters whats in the tank but not carbon from the pump itself. im not sure this would temper with fuel pressureive had injectors ultrasonically cleaned during overhaul. TB was cleaned 5k before overhauli suspected:whistling noise, rough idling,popping noise - vacuum leaks, lean FC on idletappet noise - shim not marked when head is removedoil vapor - improper valve adjustment after grind valvewhite smoke - valve not adjusted properly causing leakscan someone diagnose these noises further in details and advise me?</blockquote>
