boosting24/7 Posted June 18, 2013 Posted June 18, 2013 (edited) I've just bought a freshly build forged engine and there is a noise rattle form the cam area, its not bottom end tho, it is very loud when I start it up in the mornings or after work, when I've let the engine warm up you can heardly hear it, and when your driving you cant hear it what so ever, any info or idears would be great, Edited June 18, 2013 by boosting24/7 Quote
akyakapotter Posted June 18, 2013 Posted June 18, 2013 Forged engine sound like that till there warm mate sure some one will put me right if I'm wrong Quote
boosting24/7 Posted June 18, 2013 Author Posted June 18, 2013 Forged engine sound like that till there warm mate sure some one will put me right if I'm wrong Really just sounds odd, its doing my head in lol, sounds like a fiesta with bad tappets pmsl, Quote
akyakapotter Posted June 18, 2013 Posted June 18, 2013 (edited) Hmm maybe the cam gear isn't tensioned properly but id have thought it would do it all the time Edited June 18, 2013 by akyakapotter Quote
turbo Grant Posted June 18, 2013 Posted June 18, 2013 Sounds like valve clearences to me. A couple might be on the big side. But if its ok when warm I wouldn't really worry about it. A tappy tapper is a happy tappet as they say. The only down side is you might be loosing .2 of a mm lift on the valve/s Quote
MARC MOSS Posted June 18, 2013 Posted June 18, 2013 My Dave burwash forged engine did exactly this when cold it sounded awful, as soon as it warmed up it was quiet as a mouse Quote

boosting24/7 Posted June 18, 2013 Author Posted June 18, 2013 The head is meant to be polished and ported, and new valve seats and stems, would this be anything to do with it Quote
Danza V Posted June 21, 2013 Posted June 21, 2013 Could be valve clearances. If incorrectly set they can cause poor performance. Quote
