Have you got a short 3/8"unc bolt in the hole at front of block that goes thru to the mechanical fuel pump pushrod, that could be your oil leak. Try a bit more or less toe in at front to see if it kills the vibration.Ran COTA again last Sunday. The car ran generally well without any real problems. That's a first. I still have a vibration in the steering wheel under hard braking but it is better. I think I will need to turn the rotors and see if that makes it go away. I also have a minor oil leak from the front of the engine. Maybe a couple of ounces over the whole day. I still want to fix it and maybe I will pull the motor and have a good look.
But all in all a good full day without any real problems.
I tried a different pad material this time. Wilwood A pads were replaced with their B pad. Not much difference really. I am going to take the rotors off again and have them turned this time, maybe surface ground if I can get it done locally.
