The WP shown in the picture features an impeller that is far too far from the pump casting. The impeller on the pump has moved towards the block.

Did you ever stop and think the attorney told him NOT to tell all??? Apparently not.

I HAVE ALL THE PAPER WORK!
None of the work was done, every piece of a WP/TB job was Not replaced.
I have spend 2 hrs min. on the phone with them.
They would like me to drive the car to them (3086 mi) NFW
The water pump people suck too..... I need a paper work for the WP.
and getting that is a paIn from RUSNAK. What more do people need to prove that IT WAS NOT DONE!

(One thing is for certain, though - that WP did NOT bore out that block)

We will put that WP in your car and then we will see!

It sure looks like that impeller has moved back, and some water pump did that damage, no other way around that.

Exactly what did you pay to have replaced and what do you think was not replaced?

I have seen brand new water pumps do EXACTLY what has happened to your block.

The Reason Greg Brown spent the time, money and effort to come up with a repair fixture was because of just that type of damage on a BRAND NEW water pump on a very high dollar work of art.

A water pump can fail and cause that in no time at all. What is there that suggests they did not do the TB/WP work?

Not sure exactly what you're trying to accomplish here?

If you have an issue about a Porsche dealer's service department and their work, and the dealership won't give you the answer or action you want, take it up with Porsche USA. If they don't give you an answer you like, seek legal advice, or just drop the matter and move on.

If you're trying to incite anti-dealer sentiment or gauge opinion on the situation using the people of this community, tell the full details, and the community will decide who the winners/losers are in the story.

If you're looking for sympathy on a purchase you made that turned out less than ideally, or than expected, you probably shouldn't be buying 20 year old supercars.

For those not intimately familiar with 928's, or happy to take their chances, never buy a 928 without a thorough expert PPI, which in this case would presumably have noted a high temperature gauge when running, and provided a basis for price negotiations.

I don't think anyone should assume anything at this point. I know the situation but I won't post anything about it since I do not know the legal implications. I do know that the dealer is in the wrong.

Give Greg some time to explain when he can.

+1 That pump [Edit: doesn't appear to have] routed the block but without details of what actually happend it's hard to read between the intimated lines here. The impeller sits flush with the WP so it's 3-4mm off I am guessing.

The pump pulley is strangely corroded looking. Even if OLD, it usually is pretty shiny from belt contact. The tensioner arm pulleys look more normal and pretty newish.

So, you hare saying they charged for work but did not do it. What's the evidence for that?

svp928

He said in a previous post that the car has 3500+ miles and one year of use since the TB/WP job....I don't see what makes him think the work was NOT done....when the impeller moves on the shaft and hits the block, it causes the belt to slip and, eventually, fail. The belt leaves a black deposit Bill mentioned on the pulley- so that is what appears to have happened. I can't see the face of the impeller, so can't tell if it is the one that did the block damage. As mentioned by Greg N, this can and does happen on brand-new pumps---if this car went 3500 miles, none of the parts would still look "new", and I don't see evidence of the job NOT being done, but charged for, a year ago...

I think we need more detail of exactly what happened.....

Sorry to hear about your WP issues - having just experienced the same failure on Virginia ('87).

Here's a pic of the rebuilt WP that failed and drilled into the Virginia's block - you can see the gap between the impeller base and the WP casting.


Here's the new WP. As you can see, very little gap between impeller base and WP casting.


Good luck with the repair - fortunately, there is a solution to repair the block!

Hate to derail this fail thread..but has anyone quantified the effect of the ground down block? I suppose either cars that run hotter than normal..or maybe documented decrease in coolant flow? Be nice to see some hard data before people spend lots of moola repairing something that may or may not be an issue..

worf928

I've dealt with three examples of the "impeller machined block" syndrome. In one case the machining was light - about 1 to 2 mm - and the car ran normally. In the other two cases the damage was on the order of 3 to 4 mm and the cars ran measurably - by 6 to 10 degrees F - warmer than normal.

With a impeller migration the block is no longer like Porsche meant it to be, and to me that means it is not right, but that is just me.
Mine runs hotter than most 928's do and I am in the process of doing a "Greg Brown" repair, I will post the results.

IIRC mine had .030-.040 gone, I will know more in a day or two.
