I Recently Had My Engine Rebuilt By A1 Rally Sport (previsely A Havey Gibbs Engine) Ran The Car In 1000 Miles Slowly Starting To Give It A Bit Towards The End Of Running It In. And The Engine Sounded Like It Was Pinking The Car Was Booked In To Msd For A Live Map And Thought They Would Be Able To Cure The Problem, But They Have Tryed There Hardest And Carnt Get The Noise To Go, The Nosie Only Comes On When Its On Boost At About 5000 Revs It Sounds Like Being In A Rally Car With Stones Hitting The Underneath Of The Car Thats The Sort Of Noise It Makes. They Have Done Everything They Can And Its Not Pinking They Have Checked Everything On The Car To Make Sure Theres No Rattles, The Only Sollition Seems To Be Something Intrnal On The Engine Was Just Wondering If Any One Could Help Please Cheers James

 

If stu and the guys dont know then maybe try contact A1 or harvey, unless someone on here has had similar thing.
Good luck.

 

yeah picking car up sat from msd then taking it to a1 was just wondering if anyone had had any probs like this be for cheers
