I've seen more Audi's with sized water pumps than 928's (the ones shipped from the factory with the tensioner used in the Porkensioner).

Thats because them Audi waterpumps are rubbish, thank goodness ken did not make a pwaterpump based on those :-))))

I've used the Kempf tool for about 8 years on several of the 928's I've had. Never any issues, or failed components. I found (all '87 and later cars) that the Kempf tool needs to be ~90% of the "full tightness window" in order to match the Porsche specs (The first 5-6 times I did this with the Kempf tool, I cross checked tensions with a friends Porsche 9201 tool).

I'm also almost speechless. "Yea, though I walk through the valley of death, I will fear no belt ten light." While we reek of paranoia, you are a man who obviously goes about his world in cool passivity while others are shuddering under the chaos. Cheers to you.

Just put electrical tape over it and motor on as you have been.
Now, you know I'm kidding and mean no disrespect.

You base both of your comments on what eveidence? You are assuming a $hit loads of stuff here dude!

rexpontius

You should not take all my comments so serious, relax :-)

Imo000

Why shouldn't I? The entire thread is a technical discussion. Wouldn't it be easier to admit that you were wrong than trying to pull the old "It was just a joke" routine?

This is not a joke, I have seen 2-3 times as many WP failures on the VW 1.8-2.0L as any other brand, far in second place on the failure list is the inline 6 BMW's, the difference in these and the 928 is that it seldom does any other damage as long as they do not run them until they stop from overheating.

VW waterpumps are junk... Reman'd units are even worse... Including their t-stat housings... cheap plastic isht...

Not had any experience with the bmw pumps failing...

Gears are fine. Engine RPM rarely over 2000. I gave up playing the fool with cops a long time ago.

I am one of the ones that likes to have the warning light in case of a water pump failure. However, sometimes I wish I went with the Porken tensioner, simply because its simple to install and you don't have to worry about the belt tension. My warning light did come on during a high RPM run on the highway(about 5000). Turned out that the pump was failing, impeller was grinding against the pump body, it was machining the pump. That was a brand new Laso pump too, with only 20,000 miles on it. I retensioned the belt since new at about 4 or 5000 miles since the install, because the warning light came on. Tension was in the middle of the window. I missed the initial 1500 mile retension.

What model 928 do you have?

Bjbpe

If you are constantly revving up to 5000 rpm, you probably would have toasted gears. My engine is rarely over 3000 and then only when accelerating. If your "toasted" gears are because you are constantly way up on the speed scale, well, you probably deserve the traffic tickets and the roasted gears. And, while I'm probably old enough to be your grandfather, greg, I've learned to keep the speed reasonable.

Somehow this got out of order but my car is a 1987 S4 with 5 speed, puchased new in Germany in January 1987.
