i have just joined the forum so 1st things first, HELLO to you all. Right i have a 2006 focus st3, had the engine rebuilt with RS pistons and con rods i have a full Mongoose decat RS injectors and a 330 jamsport remap. Now like others i have developed a whirring kinda bearing noise from the engine, its worse at about 2000 revs and stops when the engine stops its almost like it runs out of puff when the engine shuts down if that makes sense, its qiute loud especially on idle, sounds as if something is really dry again if that makes sense, any help would be appreciated. All levels would appear to be good. Thanks guy's.
