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 It would seem the original part is quite outdated, and its application on the Turbo R at least a weak spot given the power.

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.

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.

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

head gaskets

I think the head gaskets have been updated, but for later cars with basically the same engine. It is a three sheet metal gasket specifically for higher horsepower engines. It is apparently identical except for one stud locator hole that needs to be added. this is according to a US owner, ex racing mechanic, who could not believe RRB were still using this old design. https://bentleyadventures.wordpress.com/category/bentley/page/2/ try this link. so i think the better gasket is available but repair shops will not fit it because it wasn't designed for the older model cars. that is exactly what happened to me, even after I made the repair garage aware of this situation.

Hello John.

Yes, I remember the discussion you had on this forum when your head gaskets had to be changed and how the repairers would only fit the original type gasket not the MLS type.

I think that a few people will try the MLS type if the supply of head gaskets stays unobtainable for too much longer.

Jake.

I will look into the MLS ones on the Arnage as per what the guy on the link did on his blog. We could be waiting into next year for gaskets!


Interesting point about this being one of the issues causing the Turbo R to be worthless. When I look at mine in the garage it certainly doesn't resemble a £6–8k car. They are incredibly classy motors, hand built, the interior stinks of quality, 6.75 litres of British muscle wrapped in a shape synonymous with luxury.

One of the factors with the head gasket issue regarding Turbo's is related to the driving habits of the owner/driver. A common fault has been found to be block and head expansion. The vehicle must be totally warmed up before hitting the gas to feel the turbo rush. It's a great feeling but without awareness can be costly.
When these cars come on the market many new owners do not know the history or driving habits of the previous owner.
The new MLS gaskets are better, but remember to warm up or blow up.

Hi,


I wonder if it is mentioned in the RR/B drivers handbook for the car.


I have a Lotus Turbo Esprit approaching 60k miles now which is worrying me with the nicosil liners but never had any issues with the turbo. I was told from day 1 by the dealer salesman that turbos needed a little time to get the oil pumped up to the bearings so have always waited anyway before heavy acceleration.



At least if I had a RR/B turbo it would have then survived.......

I wonder if anyone has contacted a high-quality head gasket manufacturer like Reintz to see if they have an interest?

Cheers- Larry B.

For what it is worth, I contacted the U.S. representative of Reinz and explained the situation about blown head gaskets; he said he would forward the info on to the Europe office, which I presume designs and manufactures head gaskets.

Cheers!

Thanks Larry. Wouldn't it be great if someone like them jumped in and offered a better quality solution. From what I've read, copper would be a far more appropriate solution for our engines.


Noticed you're from East Tennessee. Just back from there, and seriously considering shipping out the Bentley at some point.
