I have a Factory Five roadster with a 5.0 HO equipped with a trick flow topend kit installed two years ago. Experiencing what I think is a vacuum leak thats making a high pitched noise similar to a slipping fan belt thats not the fanbelt but coming from the top of the motor.
Anyone ever experienced such, or has an idea on how to identify leak. It's a leak that I can't readily identify the source.
Appreciate any advise.
Thanks
Jay
