I have a 91 GST with a refurbished head with less than 5k miles on it. When it is revved to about 6k RPM it makes a noise and the middle of the timing belt raises. The timing is supposedly off according to the local dealership, but my pop thinks it may be valve float in addition to our timing problem. We are going to check the timing this weekend and figure that out, but it does make a bad noise around the 6k mark. Its hard to describe, but it sounds bad, almost like a grind. Any ideas?
