I don't disagree with you Doc but we need a much larger sample to get a more accurate number. With only one failure it could have just as easily happened on the first pump sold or the 100th or even 1000th.

I have one of Ed's Guardian pumps on my 89. I'm in Baytown, Texas, at the moment dealing with the current 40 days and nights. If memory serves, I've had my pump on my car for about 4 years, and maybe between 14 to 18 thousand miles. It's recorded on the tag I got with the new Gates Timing Belt, I installed. I'll have to wait till I get home to provide the exact mileage.

I bought Ed's pump, cause it's hands down the best solution available. At $450.00 it's a bargain!

1 here. @ 20K miles. Other factors have prevented me from driving more, but I plan to have those things all rectified very soon. Would I buy another Guardian water pump? Yes, but since I replaced every other water pump in my 928 fleet just before I bought from Ed, it may be a while.

good to have some positive feedback on Ed's pump

There have been more Guardian pump failures than PKT failures.

I've installed a 1/2-dozen or so. No issues have been reported to me. I've no estimate of total mileage.

Mark Anderson

to be fair can we give Ed some allowance for teething pains?

worf928

You appear to be misinformed about Ed's pump.

It also fixes the problem of impeller migration.

And, it has a metal impeller. Certainly the last one I installed did.

worf928

I am aware of two Guardian 'failures', both on the same car using a non-Porsche casting. In both cases the block wasn't chewed-up, the belt didn't break: there was no damage.

I am aware of one PKT failure and that failure resulted in a destroyed engine.

worf928 - good to know but I am still wary of selling anything with a metal impeller.
I assume he pins them to the shaft which is fine - but what about the seal cartridge migrating along with the shaft and metal impeller.
I personally feel that the rubber clutch is a waste of time and money in the grand scheme of things but very willing to be persuaded - as I keep saying I have nothing bad to say about Ed's pump just looking for a cost effective solution like Mark.

It did not destroy the engine at all. The engine continues to run with a PKT fitted.

Statistical data point 1, I had a WP seize on the way to 3rd coast 2 years ago.

But - some relevant background is in order. The car had been sitting for 5 years when I got it. A new belt was installed and tensioned, then checked for tension just before the trip. On the way down there I was - ahem, moving rather well(3 digits often), the water temp rose, the warning came on, and I turned the key off(just in time).

I should have done the WP when I did the belt, but it was solid on the shaft, not a leak, squeak, or rumble from the bearing. It just decided to take the day off under duress.

In hind sight(20-20) I am doing the front of my black 88 soon, and this time - learned the lesson. I have a belt, and a water pump. mdrnf,k...

When Bertrand's water pump coupler took a dump, I contacted Ed, and asked if I should order a spare for just in case to put in the glove box. He told me it wouldn't hurt to have one but I decided it wasn't necessary. Ed also told me that Bertrand's pump casting was one of the Laso castings he experimented with in the beginning. He no longer uses anything but a Porsche WP casting. My pump was modified from a Porsche WP casting and the core I sent back to Ed was a Porsche WP casting.

My pump also has the metal impeller that is pined to the shaft. The way Ed machines the casting for his bearing cartridge, it can't move once it's in place.

I don't scrimp on parts for my car. I buy what it needs regardless of the cost. If I don't have the extra cash, I wait till I do, and the car sits. It's the only sensible approach.

CHEAP PARTS ARE NEVER CHEAP!!!!!!!!!!!!!!!!!

That's the case with other items in this thread.

Maybe there should be a kit that just grounds the warning light lead to the block.

I bought one of Ed's pumps last year, but I've only put a couple thousand miles on it or thereabouts. No problems to speak of yet.

His pump has upgrades on it compared to the stock pump and it costs half the price, and I had no intention of putting in a Geba pump with the metal impeller so it was a pretty easy decision for me. Sure, if Ed had a version that didn't have the clutch and cost way less then that might be even more tempting, but I'm cool with paying what I did while at the same time removing one more potential failure option from the mix.
