The machine shop I sent the head to told me that the head was already rebuilt and decked before from what they could see...I am getting the pinging noise and I believe I have an exhaust leak at the manifold. Will getting an adjustable cam gear help my case if I can retard or advance it by a few degrees? The leak wouldn't affect the pinging at all, correct? Also, where would be my best bet for a good cam gear that isn't too high priced, I'm not looking for performance, just something to stop the pinging!! thanks in advance!
I'm sorry if there's a thread that talks about this, if there is I can't seem to find one that talks exactly about this type of situation.
