Advise neede

Just tearing down my 66' 2.0. After removing the rockers and cam on the right side, I found this: The rocker looks ok, but this is my first re-build on a 911, and I would sure appreciate any advise. Thank you in advance! Aloha, Jon

Clogged cam spray bars? Why the rebuild? Just routine or did something break?

spray bars seemed ok. I found broken rings on #4 & #5. I guess that solves the smoke problem, although I haven't yet taken the heads apart, so I'm not sure about the guides.

Hard to tell just what it looks like from your pic, but some pitting on SC cams if not unheard of. I would send them to camgrinder and have him give you your options on them.

Cheers

When you say: "seemed ok", did you actually remove the plugs in the cam housings and clean the spray bars? What's the history on the engine? How many miles? Was the oil changed at regular intervals?

Is that an SC cam? I thought this was for the '66.

Thats unusual for a 66 camshaft. But easily repaired.

John, Thanks for the reply. How do I contact you for repair?
Unfortunately, I don't have any history on the motor. I have not pullled the plugs on the spray bars. When I shot air and carb cleaner through them, they seemed ok.
