1988 Expansion Tank Turbo R

[simonlyons]

Help

My expansion tank is split, as soon as the cooling system is pressurised it leaks a little. It had a radiator leak whcich was resolved, as soon as it was fixed the header tanks leaks.

Bentley UK have them on back order so I am a little stuck. Does anybody know where I can get one. Im going to apply a fibreglass repair to get me home but then I am stuck. Have tried numerous breakers but all to no avail. I sourced some tanks from the low pressure turbo model but they are a totally different shape. IF anybody has one to sell or knows where I can get one I would be grateful.

I bought two from a breakers but they were for the pre 84 models. Its completely different.

Im not that treacherous, had a very busy week so apologies for the delay.

I emailed Bentley on Tuesday and they confirmed they have 54 in test as the part has been on back order for a year. Fist batch split. They are like hens teeth, allegedly there is forty two turbos off the road awaiting a header tank. Bentley said if they pass the tests they will release the stock this week.

Scary, fixed a rad leak and the header tank started leaking, pressure in the system must increase greatly.

By the way i tried all the suggestions before posting, got one positive reply from Canberra in Australia. Wanted 450 quid. Intro, flying, roberts, gallimores, phantom. All to no avail.

Demand item me thinks.

For all of you looking, I have just spoken to Terry at Bentley in Crewe. He let me know the replacement expansion tanks are in teh final stages of test. Hopefully they should be released to teh network in the next two weeks.

I have fibreglassed mine as a replacement and its driveable. But I cant use it yet as its to risky.

By the way has anybody replaced their cooling pipes with silicone ones? Is it worth it?

WIll keep you posted on the progress of the test and if anybody wants two tanks for the pre 85 models Ive got two!!!

Do you have a recommendation who could do that?

[simonlyons]

You need a tank a sender and a sticker now so it's about 140 including the vat.

Gents your help, i have the new tank.

How do you fit it?? Is there a method of draining the expansion tank first or do you drain the whole system?

If theres a how to then i would be grateful.

Some advice would be good. New expansion tank fitted, system pressurised and kept overheating. Have a really reliable honest classic car guy locally ans he says that exhasut gas is getting into the cooling system and pressurising. This is stopping the thermostat opening as its full of gas. System overheats. Someones ksealed the rad about ten times so that was powerwashed through. Says it needs the head doing.

It ran with no temp issue for thr first few months. New header system pressurised . Bang.

Is this definately a leaking head or could the kseal screw the rad. He has had a sensor in the header and detected gas so im clutching at straws really. Im in a bit deep hear and would appreciate some advice on what to do. Ive spent a fortune on tyres, ball joints, bottom arms, gearbox flush etc, all electrics overhauld. Underneath the vehcile is corrosion free. Bodyworks roughbut that was next on. The budget list, not head replaced! Its an89 turbo r pretty. Ful History .

Any advice greatly appreciated. The mechanic has been great i am simply asking advice from many other bentley owners.
