I have a knocking issue that I need help with. I will provide as much detail as possible.
It is a 90 XR7 that is mostly stock except the air silencer has been removed and the previous owner changed the SC pulley to a smaller one (not sure of the size)
Symptoms
it not really a tapping sound, more like the "knuckles on a wood door" sound
Knock is loudest when car is cold and goes away as the car warms up.
it is louder when car is driven before reaching operating temp.
there is a mild loss of power and gas mileage.
the knock is rapid, rhythmic and in time with RPMs
What I know
The snout seal is starting to leak just a bit but I maintain the oil until I can change it.
The oil was just changed
No codes are reported in memory or after clearing memory
replaced the water pump and power steering pump about two weeks ago. the sound was there already.
Any help or suggestions would be greatly appreciated
