New water pump fitting: In the instructions I'm following (thanks Dwayne) he doesn't use RTV. There appeared to be quite a bit on the original WP. I was wondering if I should use it? How much to use? And how to apply it?
No goop, just the gasket.
That pump's not original if it has goop on the
gasket. The factory installed it dry.
I doubt it's original if there is goop on the
gasket. Low mileage would not be a good indicator. It is common practice (except
by Porsche), advocated by many 928 experts here over many years, to replace
pumps with timing belts at 5 year intervals (of which your car has had 6)
regardless of mileage, and one of the most well known 928 specialty shops always
gooped the gasket. Porsche wouldn't have. Only if the car was always Porsche
dealer serviced with the odo showing less than 60K miles could it have the
original belt and pump.
