Out for a drive yesterday and the car felt "lumpy". Got home and ran the usual checks, all okay. Last thing to do was to check the dizzy. So I pulled the primary dizzy lead and tried starting her. No joy. To confirm my fear I pulled the cap off the secondary dizzy and the rotor turned freely! Oh dear! It's either new or rebuilt distributor time! She's on 120,000 so it was kind of expected. I've looked at all the articles on rebuilding them but due to work commitments I haven't got time. I would like to send it off and get it done. However I can't find anywhere to do this. I've now phoned 8 places listed on the Bosch service centre website.

But none if them do this anymore (for the 993 dual dizzy)

Does anyone know a place in the UK that will do this?

Cheapest I could find new is design911 £695 + vat on an exchange basis and ECP £795 also on an exchange basis.

Any help appreciated.

There was/is someone on this board that rebuilds distributors on an exchange basis. He did mine for a really good price. Do a search and it should show up.

Steve Weiner is one that does them (here in the states) and there are at least 1 or 2 others. Sorry I can't help on your side of the pond but if you can't find someone ship it to Steve.

Seb, I had mine done last year by Mark Cohen out of Powder Springs GA. Sent Dist. to him, came back new belts and any worn parts for $175.00 plus shipping.

I was very happy with his work. His number is 770-356-1601.

I bet Colin at 9m will know someone in the UK that does this.

Direct spark conversion time!

E-mail the shop and ask them what gets replaced in the rebuild? Get the details.

Just the belt...and what else?

NineMeister

You bet, we actually repaired two broken belts last week. Pop it in the post and we'll get it back to you next day.

We normally just replace the broken belt.

If you are looking for a complete rebuild with new bearings, new sensor, new caps and rotors you should buy the Bosch exchange unit at £860+VAT.

For a minimum rebuild, I would want new bearings as well. Seeing as many go quite the distance on the first and original belt, I doubt the bearings will make it to the next belt change.

NineMeister

Never, ever seen a failed bearing in a twin head distributor but I have seen one destroy itself when it came to pieces after having its bearings replaced (badly). Just sayin'....

Guys!

Sorry I haven't had the manners to reply or indeed update you. I have been away on a (very) long business trip and this is the first opportunity I have had to do anything social on my computer for some time. Here goes.......

I removed the broken dizzy after much blood and swearing via the use of a small crow bar/crows feet bar. This is the first time I have ever used such a medieval tool but it was actually necessary. No other methods worked, not even drilling a hole in the tinware and trying to punch it out. It really was stuck right in there!

I found a very good independent specialist to do a full rebuild for me. His name is "Sid" aka "Sid the spanner". His garage is called "Porsche Torque" and it is located near Heathrow in a town called Uxbridge.

It was a complete rebuild which included a new belt, bearings, cap, pin and o-ring. The body plus all parts that were not new were cleaned prior to re-assembly.

I have no idea where Sid sourced the bearings but the belt was bought from euro car parts for £8 and all other parts (bearings aside) were bought from Porsche. Sid can supply rebuilt distributors on an exchange basis for £400 all in. This means everything that was done on mine (belt, bearings, caps, pin, o-ring etc) is in included in the price. This is a hell of a lot cheaper than anywhere else for the level of parts and work that is done. Sids details are as follows........

The below pictures are not in order but I will do my best to explain each pic.

Distributor removed I took the opportunity to clean and paint the area. Leaves, nutshells, thick grime and several twigs were found in what I thought what was already a very clean engine bay.



Stripped down with new bearings trial fitted.



Cleaned body and internal working parts before cleaning.




Old snapped belt



Old rusty bearings. Note the rust on them. A few had started to eat themselves. I would strongly advise getting these replaced when you have your belt done. Mines on 105k now and is a 95' but you all know its only a matter of time before the inevitable happens. Get it fixed before you hole a piston when your bearings seize! (scare tactics are and were in use..... )



Stripped down......





Pre installation.



And about to go on!



Done!

This brings up a topic that I thought was covered before on RL but I couldn't find the thread. Can a broken distributor belt cause any significant damage to our 993 engines?

I thought it depended on where the distributor stops its path after belt breaks that determines potential severe internal engine damage. However, I was just visiting a mechanic who has been working on 993's for many years and said that a broken distributor belt is never really a concern as the engine just loses power and can be driven in this "limp" mode back to a shop to be repaired.

Any one seen any severe damage with this type of situation?

Can I ask about the crowbar technique to remove the distributor assembly. I want to replace the belt on mine as preventative maintenance but the assembly is firmly stuck in place and won't budge. I am abit hesitant to use medieval tools since I am more likely to break things in the process (body parts as well as Porsche parts). Any tips appreciated.

I've used the rope method from this link on a stubborn distributor.
