Hello, here is my second uoa on the car. I've been using it a lot more recently. Silicone is high at 162. Could it be because I had the valve covers changed? Lead went up from 20 to 71 when comparing it to the first uoa. Below are the results and the thread to the first uoa of this car to compare results.
