New RX7 project

[andrewb70]

Just curious if it's back on the road yet?

Thanks for asking!



I was out of town and actually sort of lost interest for a short time. Rather frustrating. However in the past few days I have approached it again with more enthusiasm. I pulled the driver's side head and indeed found the #7 intake valve kissed the intake. So in the end the #6 and #7 pistons made contact with the intake valves. I am not really sure why just those two. Why not all 8? Perhaps its just inconsistencies in the cam profile or in the valve springs. The valves in question could have has slightly less open valve spring pressure than the other valves and thus floated more easily.

I will replace the two bent valves and all the valve springs. I may also take the time and shim the springs to the exact installed heights that was recommended by Comp. I am using the 918 springs.
