Engine knock - ZR-1 Net Registry Forums

Perry Mitchell · 10-23-2023

I have been doing research on this subject, but have not come up with anything definitive. This motor came from a wrecked 91 ZR1 with only 17,000 miles on the odometer. It has been transplanted into my 67 Camaro that has been an ongoing project since 2010. I?ve been able to start it for the last several years but have yet been able to take it on the road. It starts, idles, and revs well. However, it has this very annoying Knock that I am worried about. To me, it sounds like a rod knock. All my research says it is probably the dual mass clutch fly wheel assembly but this motor is connected to a 700 R4 transmission. Does the camshaft chain assembly make that kind of noise? Any and all help will be appreciated. Thank you.

I tried downloading a video so you could hear it but I guess I don?t know how.
