a Camshaft and follower replacement typically costs about £800 - £1000 if you have to pay someone to do it.
camshafts typically need to be replaced at 45 - 50k miles on an average use Griff or Chim.
This is primarily because a Rover V8 was built with 150hp and a griffith TVR V8 has double!!
Double the power generally means half the cam life.
what are you worrying about my diesel Audi has just cost £450 for a basic service!!

I fail to see how the increase in power determines the life of the cam?
More power requires more lift, which in turn requires more spring presures, the 500 also runs slightly heavier valves, again more grief for the cam, and lastly the actual profile of the cam will try and let the follower/tappet try and dig into the cam.Its the fact that the cam slams open and shuts the valves with some heavy valve springs to boot. The standard cam is a lot more gentle with a smoother lift as its not as high. You can get a cam kitt ie everything you will need apart from oil and filter and sump gasket from V8 developments for about £375 and i believe they do a fitting service.

1 month into ownership and have been told I need a new camshaft.
I'm not sure I can take this
This is great news, it's an opportunity to choose from the range of cams available and tailor your car for your preferences / begin your never-ending programme of upgrades (delete according to budget)I'm not sure I can take this

if your cam has gone it would probably have been down on power that you may not have noticed in a month of ownership get it done if you can! you will be grinning again with all that regained powerSam, it's a real bummer, mine went 3 weeks after I bought it in June last year, I lost three lobes on the cam. Car had done 52k miles but it was the oil pick up pipe that had become detached. Other problems are oil starvation, when the oil pick up strainer gets clogged, with excess silicon sealant from when the factory fitted the sump, they didn't use cork gaskets!
I had V8D do my rebuild, with one of Rob's (V8 Racing) stealth cams fitted, that is some cam profile!!! tractable around town, manic on the open road
I also had the all steel rocker gear fitted, plus having the cylinder block liners replaced with stepped liners, new pistons, rings, bearings, oil pump, cross bolted and balanced bottom end, head ported, intake matched and ACT intake and water hoses fitted, also had the silicon engine mounts from SC Power.
I now know that the engine will not have all of the issues that pop up on here so depressingly regularly.
As one of the previous posters mentioned look on it as your opportunity to have the cam of your choice fitted but consider the other elements such as liners.
Good luck

70,000+ miles, loads of TDs, loads of V maxs, and it's still banging out 280+ bhp 330+ lb ft.
still on original cam and engine, it's only ever needed a rocker and valley gasket.
mind you mine has it's oil changed every 2k.
My last 390SE lasted 7000 miles from new before it ran an exhaust cam lobe. Vive la difference as they say in Peckham.still on original cam and engine, it's only ever needed a rocker and valley gasket.

Hi Everyone
Thanks for all your comments.
I took the Griff to Tom @ TH Works who took it for a spin and said that it sounded like "there's no cam left"- oh dear!
He gave me various options on cam, but since I live in London, and I need her to behave in traffic, I went for a standard profile cam supplied by Kent cams (IIRC).
The Griff has only done 22k miles
He took a look over the rest of the car and said it had the best chassis he'd seen in a long time "as new", which is some relief.
I'm not sure I can give specific details of cost, but the cam change parts and associated labour etc comes in under £2000.
I had noticed a drop in power as the noise had increased so I'm looking forward to the increase in power after the work.
Concerning the previous owner, I'm not sure... He was a decent guy and was honest with me (although the cam wasnt mentioned), but did say that the car had been given a going over presale by Kerridges TVR and they'd said it was good.
I'm not sure I'm up for giving him an ear-full, unless you think it's out of order.
I'll update this thread with news
Edit... I've just searched a few threads and it seems that this could be quite £££ compared to what some people have paid. I'm going to get Tom to give me breakdown of what work he'd going to do. If it's standard cam swap, it'll probably go to V8D instead!
