My engines(95 RA) started knocking,mostley at lower reves.It comes and goes,but is there more often than not. It's louder under the car,and sounds like it's from the passenger front head.
I was wondering what the difference in sound was like between head and block knock? Is it possible the water pump's knocking(it was making a dry bearing noise the other day)
Does anyone know a good garage near luton?

Thanks,Tim
