Listen to what Greg Brown has to say. Even if your block was contacted by the water pump all is not lost.
You'll know when you open it up and see or don't see score marks where the impeller contacted the block. If they are there, get the tool from this group and repair your block. It used to be if this happened your block was junk. Now it is an "opportunity" to get to know your car even more intimately. Look at the detailed write ups on water pump replacement. You'll get through it no problem.

i ordered the flywheel lock tool , the timingbelt tool, all the rollers, the lasso pump ,,in fact ,the whole kit.

the sound it makes is not so bad , it sounds like a bad rollerbearing. i think if the propeller hits the block ,,the sound would be louder and different.more scraping like.
i drove 25 km with the sound, i think everyboduy would have driven this car with the sound i hear.

how can this happen that the propeller hits the block, first i was thinkng it was the airpump, so i drove home.
at home i listned wit a stick and also a tube,and it came from the wp or somewhere around for sure. difficult to locate, but it sure isnt the other belt driven accesoires.

than,
something strange with the numbers, it seems its not a us-car , but it was imported from the states ten years ago?????

i ordered and send the shop my vin and engine numbers,
and the engine numbers ,,i dont know all details about vins and matching numbers, but something isnt right i think.he shop mailed me its not a us car.
this is my vin and engine number
wpozzzs2zes862597
engine
m28/20
s1eo7122

if it was a row the engine should be a m28/22 ?

strange,,,

Does it have a VIN in the windshield?

Can you show a good engine picture, showing distributor?

The waterpump contact may not make appreciable noise due to lubrication with water as the impellor does its machining of the aluminum. Hopefully it will be ok. The advice to not run it was not given lightly by chicken-little.

It is definitely a US car. The last 6 digits confirm that (86xxxx is US VIN range).

The VIN stampings on US cars are all "zzz" except for the correct one on the edge of the windscreen, and the VIN plate.

That is very interesting....a German made car made for the U.S. reimported back to Europe. In this case, ignore everything I said about it being an interference engine.

Amen!

Bart - One other thing just for fun, you can look down the top holes of your timing belt covers and watch how your timing belt tracks as your engine is running. When my pump was making that noise, when it rattled, I could see the belt go a little off center. But since your parts are on the way, you could just take the passenger side cover off and watch it.

So with your car being shipped back and forth, back and forth shouldn't you get some sort of carbon credit for the distance covered with no emissions (from YOUR car) Like a PZEV almost! Think of all the KMs traveled with the engine off. You'd have saved way more fuel than those silly cars that shut off at stoplights!

strange, someone at 928 specialists, told me "this(bold)" in an email, so i was thinking i have an european car
Actually, the VIN is a European VIN (ZZZ in the middle instead of 92?. There were basically two designations - Rest of world or US versions.

there are a lot us cars imported , the most i have seen for sale overhere are us cars, they come back because once 25 years old all taxes drop to almost zero. that is why i bought a 84.
taxes for a 92 are 2000 euro and more,,,every year.

i have seen dwayne's topic about the waterpumpdamage. that scares me of, really.... i hope my pump didnt dammaged the block.

Your can is unequivocably a US model.

There is only one single 928 in the world with the VIN ending in "ES862597" - that's how I looked up your complete VIN, I just ran a database query on VIN's ending in that.

US models have the "ZZZ" VIN on the various parts except the official tags.

The last 6 digits also identify yours as a US model - the range "86xxxx" is for North America. Rest of World would be "84xxxx" in '86.

hey , thanks for the vin check,

i have removed the pasenger side tb cover, belt seems ok, does not walk. does not look verry old
the tensioner roller spins free, but does not spin when the engine runs.
it does not touch the belt. dont know if it should touch. maby the belt is to hard tensioned. camgears show some wear at the top of the teeth.
the sound can be the pump or some roller, i cant locate that sound for sure. it deffenitly needs attention.with a stick on my ear it sounds like a ballbearing that missing some ***** and turns with cracking grinding sound, the sound travels trough the waterhose.(the metal corner on top of the engine.)

my parts are shipped, maby they arrive before next weekend.

i have two options,
first,
repair the car on my driveway where it is now in open air. it stands on gravel . the driveway goes slightly up hill.
second
drive it to my wintergarage 4 miles away and do the repair. towing is not possible into that underground garage.dont drive it seems the safest.
on the other hand,,,i drove it 30 miles with that sound. i noticed the sound and drove home to investigate,,i hope its not a dammaged block,
the temp was like normal , in the midle.

i think ill go for the first ,repair it where it is right now, i think its way more simple on my 84 than on the S4. i think if i can lift only the front of the car i can get everywhere.
i am scared to drive it, i wish i could remove the whole tb cover and feel those rolers. i wish i could start right now.


my riviera has realy bad water pump house dammage,realy bad scores in there , i didnt replace that , i just replaced the pump long time ago when it made bad sound (it was not that pump that damaged the block) ,the engine does not overheat with the damage.

is the 928 realy running hot if some scores are in the pump house?

I think you have it backwards. The dirty sex part is like when you're exiting a turn and trying to keep the nose pointed ahead as you modulate into full throttle, maybe with some flying bits of rubber and grass, then overcook it just enough to spin out and the dust and smoke blows through the open windows. Then you put it in 1st and blast off again.

The repairs are more like making the bed afterward, with a big smile on your face.

riviera455

at last,i have all the parts, the car is allready jacked up, ready to start on the tb tomorrow in the morning. the parts where kept in foreign customs for more than 12 days
i hope i dont find something bad under the covers,,i didnt started on the job yet ,,i wanted to have all the parts first.
the new laso pump looks great, i hope i dont have any block damage. otherwise ,,,,
the sad thing, i have to repair the car outside because i dont want to drive it to my workspace ,,,an it will be a rainy day tomorrow i hope i have some dry hours),,also saturday will be rainy.


i also have the replacement ac headunit , and allready replaced the shutoff valve. the old valve was not closing , i know that for sure now. the vacuum check valve was also broken, had to suck realy hard to get air trough it.
with some luck i have a car with everything working this weekend.

never did a timingbelt job before on any car, but i think with all the help and links, it will be an easy thing to do.
i will go slow on this. and a 84 looks way more easy.
