Head gaskets: what's going on with supply?

Does anyone know the full story of what's happening with the supply head gaskets? Mine blew a while back now and I'm unable to get the car back on the road due to there being no gaskets out there.


These are the things I have been told:


Prasad Automotive
They've been telling Bentley for years there is a problem with the head gaskets and finally they have listened to them and are redesigning them.


Bentley Tunbridge Wells
Part is being updated, 200 so far on back order.


Starmans
PA Wood are making some.



PA Wood
They have made some are currently testing them. Weeks away from release if all goes well.



Flying Spares
They have some in development and being tested. one or two months away. Bentley are also developing some.


Has anyone got the whole story? It would seem the original part is quite outdated, and its application on the Turbo R at least a weak spot given the power.

This is Introcars explanation.

Obviously they have the same problem as other suppliers in that it is taking much longer than they thought to get head gaskets back.

Thanks Jake. Interesting as it is at odds with some of what I've been told. I was under the impression it was a completely new gasket about to be released, whereas the video says all that is happening is the existing stock is being examined, any visual faults seen will result in rejects and the rest restocked.

Hi,


I only know of 2 RR/B repair specialist contacts I have in the UK that actually have some complete decoke kits that include the head gaskets.


Neither are prepared to sell them on as it reduces the chances of them getting the work should they require them for a customers car.


I do hope the supplier/dealers when they do become available don't see it as an opportunity to put any extorionate price increase on the parts..


The increase from a 185HP to 400HP engine power of later cars does seem a logical reason for failures especially as so many later cars have had far greater numbers of issues.

Agreed. And also the length of service. Materials used for these gaskets must surely have moved on a long way since first introduced. I was hoping for an updated part, not one simply checked over visually for imperfections and then restocked.

Chances are that those gaskets they have are the same ones that originally failed. (new old stock)
The asbestos/composite/metal gaskets were never meant to withstand the combustions pressures of a boosted engine.

These guys in Austria have the measurements on file, they can reproduce the head gaskets:

Note: i copied this from a german-speaking forum, all caveats apply. But worth a call!

Jeff,


You are absolutely right....they are all OLD unused old stock.....hence why too they don't want to sell them as they too would not want to see them used on later cars.


Both of them feel these would be OK for the older lower BHP cars as they were pre the issues with the ones that appear to have a concerns and been sent back.

I am very glad I can get in my old Shadow and give it the beans regardless of the temperature of the engine. Having to be a bit careful with the accelerator on later high BHP engines, until they have warmed up, is not for me.

Makes me wonder how long it will be before cars that have had the head gaskets changed once, will need it again. No surprise that good Bentley Turbos can be had for less than £10,000 and falling.

A bit sad really that a long known issue was never corrected and probably never will be now.

Jake.

Hi Jake,


I am so glad none of my classic cars even have ECU's too. I can cope with a few (well more than a few) Lucas LRA relays and all the stepper motors but the electrics and electronics on these cars today just ruin it for being able to be looked after by a DIY enthusiast.


My friend last year gave up his Arnage to a breakers after spending more than the car was worth at RR/B dealers trying to get the electrics sorted and still had problems.


He went straight out and bought a Shadow 11 and loves it. Has had no problems over the last year and much happier for it.


I think the newer cars will depreciate very rapidly for so many reasons.


All the best


Steve
