I got a really good deal from Euro Car Parts for a genuine water pump for a 928 S4 - well under half price. Avoid the cheap non-originals, because I had to return one once that was rubbing badly it's impeller to it's body from new! I get the water pump changed when I get the cam belts renewed, and I especially would recommend changing all these and the water & fuel hoses while the engine is out.
Another great episode .... Water pump is a regular service replacement item , bin and replace... - Oh i presume you are living on Rennlist 928 forum amazing knowledge base..... and well done for completing the first 928 right of passage, the undoing of the 4000 sump bolts 😀👍
Thanks GF04RCE, yes, Im on Rennlist and the relevant Facebook groups - such amazing resources. Water pump is now a wall hanging (I'm slowly building up a collection of memorabilia from cars - I'll try to remember to show in next video). And wow, yes those sump bolts...
Hi Todd! Great work on your 928. I’ve been through this journey with my 1980 928 AUTO (which is also in Grand Prix White). I’d recommend a water pump with a plastic impeller rather than a metal one, as it won’t damage the engine block if the impeller ever became loose on its shaft through wear. I fitted a LASO one (cost a couple of hundred pounds). It’s worth joining Porsche Club GB too, as you can get advice from their 928 technical lead on anything you’re not sure about. 😊
I have the water pump on order from Design911 (so hopefully good). PK tensioner - I was planning to rebuild the existing one to avoid the heavy cost. I don't know how long I will eventually keep the car once complete so figured this is the best route. Being a non-interference engine also reduces the timing belt risk.. What do you think?
@@MrToddgibbs I'd double check with Design911 on what make of water pump it is - if it was a choice between rebuilding the original tensioner and foregoing the PK OR putting extra £ into the correct water pump, correct water pump wins everytime IMHO
Hi! Thanks for sharing your journey of restoring your 928. I was the guy restoring a GTS. I have purchased several QWP waterpumps from the US on eBay. They are super cheap and worked on my 944, 968 and 928. Best wishes
Hey Palatina, Yes I remember :) GTS is beautiful. Thanks for the water pump tip, I'll have a look - I think the consensus is to bin this old pump. Thanks for watching and have a good weekend!
@@MrToddgibbs Hi, yes, consensus is to change and replace everything you can. Seals, bearings, bolts... woodruff keys... I repaired the alternator and servo pump... just for information. Does your car have an AC? You probably need as well a radiator. I ordered mine from China on Alibaba... however it still hasn't arrived in Taiwan. Looking forward to your next moves.
Hey again! Im about to order the gasket kit, which I think has all gaskets (so those will be replaced). I need to inspect the alternator and servo pump, but from what I can see these are easy to access items when the engine is fitted, so no big deal if they fail later (but I will probably replace if not too expensive). Mine has A/C but it looks like it hasn't worked for a few years (no belt for a starter!). Im assuming I will need to replace both radiators. What Im starting to think about is the fuel lines and vacuum pipes. Vacuum I can source from _anywhere_ but the fuel lines are a bit more specialised and I may have to go OEM. Its going to get interesting when the engine is back together and focus changes to the rest of the car!
@@MrToddgibbs Do you have an external and in-tank fuel pump? I haven't addressed this yet. Fuel lines aren't that much of a worry to my car at the moment. But on mine the inner plastic fenders are completely brittle and need to be replaced. I assume that they are special on a GTS as the car is wider. I don't know if I mentioned it before. I am a German expat in Taiwan and the GTS needs to get road legal for Germany. I am not allowed to register it anymore in Taiwan as a scrapping incentive has been paid for this car
That is a difficult question - my car doesn't even have a fuel tank cradle (I think in the first video you can see that its held in place with a bicycle inner tube!. I have actually just bought a cradle on Ebay so once that arrives I can start at the back and review/rebuild/fix the fuelling. Short answer, no, there is only a fuel pump in the rear wheel arch at the moment (but there should be 2 - no idea if the tank has one inside...will find out soon!). Yeah I assume your GTS will have quite specific body parts, I wonder how available those are? Does that mean you aren't allowed to drive not at all in Taiwan? That would be a shame :(
I know I'm coming to this late but...that's a wet sleeve cylinder block...you can change individual sleeves...obviously I've missed something from a future video ! 😅
Hey Adnan, To be honest its not that bad - its pretty much just a straight swap when you have it stripped down as much as I did. Cost was £900. It's a low mileage engine and just needs cleaning up (probably in the next video). I can probably sell the old block/bits for a few hundred. Thanks for watching :)
Hi Pedro! It's not too bad with the matching numbers - with these older car Porsche don't record the exact numbers per vehicle. The best you can trace is that the engine is built around the same time, expected size, etc. My replacement engine is very similar build sequence (900 later) and exactly the same specification; so its all good :) Thanks and stay tuned!
Hi Todd, Enjoying your rebuilding process and your doing a great job✅ I had a feeling your engine would be toast😩 They are nice cars and I have a 1981, manual Platinum on cup rims,with mild upgrades But they are typical European car Your always “Tinkering “ with them Cheers Todd Frank
Hi Frank, yes its just my luck. At least I don't need to get those broken studs out now :) Shame you can't post photos here, would love to see your car!
Hello Todd, Yes I’ll get some pics of my car to you It’s funny with 928’s as they all have stories as they change owners over time Mine is a 2 owner 110 miles from new,and it was garaged stored from 11yrs,but still very nice Currently it has been playing “Russian Roulette “ (Stopping) in all the wrong places)😩 So I’m going through the electrics to find the problem About 9 yrs ago I had a 1979 manual and seriously considered making a resto mod with a 6.2 LS engine and 6 speed The perfect engine weight wise is the Cadillac Escalade iron block,alloy heads,as they are strong internally But with having a business I don’t have the time to devote to a project Your in the right country for getting spare parts etc Todd,as here in Vancouver BC replacement parts have to come from the U S Cheers Frank😷
Another great video and progress,as others have said the water pump is a consumable so replace and get a plastic impeller. Did you think of getting the new block sent direct to the Engineering company first to check bearings and install new piston rings. You could put a lot of effort into building this back up only to find an issue with it later?
Hi Gary, thanks and thank you for watching! No, I didn't actually think of that... would have been smart! This might be one of my classic fingers-crossed moments. Hmmm, now you have me wondering; I wasn't planning on doing any bottom-end work...
Too bad about your block. Replacement sure looks better inside. Any broken bolts on that one? I hope the crank is fine. I have always heard they are very strong and reliable. I have always wanted a 928. They are really an incredible car.
Yeah, I had hoped it could be saved, but it is what it is... The new one seems good - no snapped studs, crank doesn't wobble or anything. There is less on the short block that I realised, oil pump, etc are all missing - so I have a few days of moving stuff across from the old - but thats fine. Lets see what happens next.... we should run a sweep-stake :)
i went down that road before, just rotate the crankshaft so the piston you gonna clean is on botom dead center, aply grease arround the edge of the piston, then rotate back to top dead center, this is to catch any residue that may fall between the piston and the cylinder, then with green scotch brite pads and wd40 clean the cylinders, is tedious to do but that way you don't risk scratching the pistons, when you find a particular hard spot of carbon with a head gasket scraper you can brake it but mind always not to scratch the cylinders or the pistons, check out this video, it helped me alot th-cam.com/video/ZlGgkJQJM90/w-d-xo.html&ab_channel=HumbleMechanic
Todd, let that water pump go brother it's not worth trying to refurbish it. Keep up the fight!
lol, ok :). I'll trying to pick a plastic impeller one now. Thanks for watching!

Good quality water pump and PK Tensioner
I have the water pump on order from Design911 (so hopefully good).
PK tensioner - I was planning to rebuild the existing one to avoid the heavy cost. I don't know how long I will eventually keep the car once complete so figured this is the best route. Being a non-interference engine also reduces the timing belt risk..
What do you think?
@@MrToddgibbs I'd double check with Design911 on what make of water pump it is - if it was a choice between rebuilding the original tensioner and foregoing the PK OR putting extra £ into the correct water pump, correct water pump wins everytime IMHO

Hi Matt, yes I believe you can - but I was advised that it will cost more than a replacement block.
Dam that would be my worst nightmare if my engine had to be changed. Out of curiosity how much did it cost
Hey Adnan, To be honest its not that bad - its pretty much just a straight swap when you have it stripped down as much as I did.
Cost was £900. It's a low mileage engine and just needs cleaning up (probably in the next video). I can probably sell the old block/bits for a few hundred.

Thanks Tood for another excellent vídeo. I M sorry y could t sabe your block to keep original match Numbers but it isnt the end of the word. Regards

Hi Todd,

I had a feeling your engine would be toast😩
They are nice cars and I have a 1981, manual Platinum on cup rims,with mild upgrades
But they are typical European car
Your always “Tinkering “ with them
Cheers Todd

Hi Frank, yes its just my luck. At least I don't need to get those broken studs out now :) Shame you can't post photos here, would love to see your car!
Hello Todd,
Yes I’ll get some pics of my car to you
It’s funny with 928’s as they all have stories as they change owners over time
Mine is a 2 owner 110 miles from new,and it was garaged stored from 11yrs,but still very nice
Currently it has been playing “Russian Roulette “ (Stopping) in all the wrong places)😩
So I’m going through the electrics to find the problem
About 9 yrs ago I had a 1979 manual and seriously considered making a resto mod with a 6.2 LS engine and 6 speed
The perfect engine weight wise is the Cadillac Escalade iron block,alloy heads,as they are strong internally
But with having a business I don’t have the time to devote to a project
Your in the right country for getting spare parts etc Todd,as here in Vancouver BC replacement parts have to come from the U S
Cheers Frank😷
