11/5/2010 Just thought I'd add a bit of news. I've found a company that can fabricate the now unobtainable water tube 047 121 073A for an reasonable one off price. I had it made in stainless steel though you could have mild steel too which would be slightly cheaper. If there was enough interest on the forum I could approach them about the costs of getting a batch made. Vince Matthews 924 2.0

For bearings and oil seals Id consider VAG parts. Its nonsense to call the 924 engine a 'van engine', but it did share some oil seals with the Transporter low compression variant of this engine. Ive always assumed that the steel crank shared common dimensions with the cast crank used in other 2 litre versions too? Failing this youll have to get your bearings re-coated, like on a real classic car. Performance versions from Vandervell etc may be available too.

As these are a standard part on most cars now I wondered if anyone had tried using a non-Porsche one and adapting the mounting and electrical connector to suit the 924. There must be a limited set of parameters that have to be satisfied for it to work? Just a thought . . . Oh and Porsche no longer stock part number 047 121 073A the metal water tube that connects the 'hose with the bleed valve on' to the 'the n/s hose from the top of the radiator'. I'm not sure if using copper pipe would cause corrosion problems (given the water is in contact with steel and aluminium as well).

Porscheshop have a policy of buying up parts that they beleive to becoming unobtainable. It would be well worthwhile contacting them. On the subject of the pulse generator, John Barnatt (924 Nutter) has been looking at the posibility of using one from a Boxster. It will require an extension to the wireing and a spacer but it seems doable.

 

[924nutter]

The only but expensive way is to buy five sets of the centre thrust bearing which are £6 per shell more expensive than the other bearings and get a top class engineering workshop to machine just the thrust faces away from four pairs of them. IAs recently as early this year the thrust bearing was still available at £28 per shell. I have spent many hours on the internet searching for main bearings even VAG sites and no joy. I need these for my 924 t rebuild. Then I was fortunate enough to buy some +0.5 kolbenschmidt (?) pistons for the Turbo from ebay that came with a set of std big ends and mains. Then I bought a complete bottom end which was worth the price because of the brand new but now unobtainable oil pump. In a few months I may have a set of std for sale but nnot till Febraury at least

 

[944 man]

Having your own bearing re-lined is still an option too.

 

[924nutter]

Yes, it is always an option if you can find anyone who does it. Do you know, for the benefit of members, anywhere that does re-metalling?

 

[944 man]

Theres a place in North East Yorkshire on the coast, but I cant remember where exactly. My girlfriends father had some bearings re-lined there quite recently: I'll post the details when I have them.

hi,i am new to the forum so please excuse any mistakes.do you know if a plastic fuel tank from a 944/968 will fit a 924 turbo mine has started to leak any info would be greatfully received many thanks .gjh

 

[Northern924]

We are talking about the flywheel (reference) sensor on the S aren't we? IIRC people have used one from a BMW in the past, the ones used for the E36/38/39 apparently fit, have the same connector etc. Never heard of anyone doing a tank coversion to the pastics one though

 

[geoff Ives]

I think that you will find that the Flywheel sensor refered to is for the Series 2 Turbo. This was manufactured by Seimens and is no longer made.

 

[Northern924]

Ah no problem, sound have read it fully lol, just read flywheel sensor and jumped in []

 

[924nutter]

I have found a working sensor and have my trusty 924T up and running again. With the readings I took, firstly the gentleman who suggetsed a resistance of 600/1600 was wide of the mark. The DC resistance of the sensor is 0.5/8.5 ohms, and having sliced a dud one in half these are the sort of values I would expect based on my observations. I have a couple of lines of investigation open including a reply from someone at VDO, (Siemens became Seimens VDO then VDO became a separate name again[long story short]) I also have some winding wire if the correct guages (36swg and 49 swg) so it should be possible to reproduce the internal windings with a view to constructing a working sensor, ultimately. If I succeed then I will publish the method.

Anyway have a look at the finished article:-

Nice. Who is the company and, if you don't mind telling us, how much for your stainless part?

The company is called Competition Fabrications of Attleborough, Norfolk and the water tube was £40 for a one off. It would be £30-35 in mild steel (as original) and I would try to negotiate a group discount if enough people were interested. Obviously there would be postage costs etc. as well. I don't know how much the OPC price would have been and my copy of PET doesn't help - I would guess between £30 to £50 easily. I have gone down this road because I had to replace a couple of hoses and the new ones wouldn't seal properly on the rusted & pitted surface of the water tube. -
