"Hi Enrico,
After a few more months I'm writing back just to inform that everything is okay and that 'Italia Exotic' is doing fine.
I've been very busy with some interesting cars to work on. Besides my Shamal, I've been doing some work on a '93 Spyder 4v and some 3200 GTs. I'm expecting the first Ghibli Cup in Portugal. That came from Belgium to Spain, and now to Portugal...
At the same time, some Ferraris too.
I've a lot of new experiences that I would like to write about, to help some owners who sometimes face a few 'funny things' with their Maserati.
I've a lot of very good photos of the last Historic Festival in Porto where some very good Maseratis raced. It was a great weekend here in July. I'll send them to you very soon.
For now, I beg you to post this issue regarding the spark plug rubber sleeve - Beru - that was used from '91 on the Shamal and '92/'93 in all Biturbos up to the the use of direct ignition...
We all know that Maserati must have been a funny place to work, back in the 90's. I say this because they had the time to make some interesting things.
Take this as an example.
I'm currently performing a major job on my Shamal, a few days ago I took out all the ignition cables... all but one, cylinder number 3, that was completely 'stuck' to the spark plug.
When I tried a little torsion movement I heard a click inside the rubber sleeve connected to the spark plug.
Of course I had broken it!!
I had to break the whole thing to remove the remainder of the sleeve. Since I was about to remove the rocker covers, to change the rubber seal, destroying it was not a major problem.
Well, since Maserati only sell the full set of ignition cables at an astonishing price, I was a little sad about this, but life goes on...
When I looked at the rubber sleeve I noticed that the last 3 digits of the Beru reference had been removed.
...Well, I like mysteries...
The Beru reference was 0 300 332 ***. I looked at the '93 Spyder and removed one of the cables. They are the same, only the length of the cable is different... And there it was, the complete Beru reference: 0 300 332 ???.
So, the first funny thing is... In 1991 Maserati didn't have the exclusivity from Beru for the ignition leads so, the last 3 digits were removed.
But in 1992 and 1993, Beru gave Maserati the exclusive rights to that reference so it was no longer removed.
I called the Beru dealer here in Portugal, and there was no reference to [0 300 332 ???] in their aftermarket catalogue. But, I already (almost) expected this!!
I dug a little more and found a Beru rubber sleeve with the reference [0 300 332 ???]. From my own experiences, usually when a partner 'gives' a car maker exclusivity for a part, they tend to change a digit from the original part...
I sent an e-mail to Beru Germany to ask for the 0 300 332 ??? or the part that substitutes that.
And, 'voilą' Beru confirmed that reference 0 300 332 ??? is the same as 0 300 332 ???...
This rubber sleeve also fits the 2.0-litre 20v and 3.6-litre V8 Audi engines.
So, the second 'funny thing' is that for only EURO 40, I can get the part and fit it myself.
For those of you who are unaware, ignition cables are a very important component for correct engine performance. Over a period of time, they suffer from the very high temperatures that they sometimes have to endure.
When opting for Beru leads, Maserati did well, since they are one of the finest makes on the market, far superior to the earlier 'Bougicord' leads fitted to the 2.24v.
Remember, that this is a part that you must remove every 10,000kms on the 2-litre and Shamal engines to change the spark plugs... So, over time and with the heat, IT IS NOT VERY DIFFICULT TO BREAK ONE INTERNALLY whilst removing it!!
The silicone cable slips into the rubber sleeve far easier with the aid of a fine machine oil, or equivalent, and then the top end is screwed into the tip of the connector inside the rubber sleeve which is of a 'saw-tooth' type.
So, if you break the rubber sleeve of the spark plug on your Maserati, contact a Beru dealer quoting part number: 0 300 332 ??? or internal Beru reference: ZLE ???
One final piece of advice! It's a good idea to apply some Beru grease 0 890 300 029 (costing around EURO 7) to the ceramic part of the spark plug. This way, no matter how long, or how hot it will get, you will always be able to remove them out without stressing... the component or YOUR MIND!
Hope it was a valid issue...
Regards,
Miguel." |
