TVR Power 100k mile warrenty vs RV8 cam wear

[dog man]

So how do TVR power guarantee their engines for 100k if it's true that most RV8 cams dont last longer than 50k?

Are they just prepared to change theirs if one does go?

[TV8]

look at how many TVRs have done that 100k mileage on the for sale section. Not that many cars have done that mileage after 10+ years, let alone 5. Good piece of mind for failure but not that many claims for wear imho.

I've got a lot of history with mine and not one single reciept or mention of a cam change, even after covering 112,000 miles.

It could probably do with a change now though I reckon.

[winters]

My cam was rounded on a few lobes after 40ish k (I think it was). Apparently this can often be attributed to some less than brilliant original parts that were fitted at the factory. So in theory shouldn't happen again so quickly...

I think the small print will tell you Dom services it during the warranty. Even at 12000 miles per annum they also get the income from a least 8 services so a cam change on a few aint no big deal

Also, most of the reason for premature cam wear is down to using Mobil 1 oil that TVR used to recommend (due to a sponsorship deal I think). A lot of owners still use it because it says so in the engine bay, but in reality it is far too thin for the engine, so does not really oil the cam below 1k revs. Use a nice thick oil like Valvoline VR1 and you shouldn't have the cam wear problem

i heard exactly the same as that from RPI, i had a chat on the phone once, the guy is so passionate about rover v8's and he recond mobile 1 was no good for these engines and said he same regarding a possible sponsorship deal

I know of RV8s that have done only a few thousand miles between cam changes to those that have done over 120k on the same cam.

would there be any logic in that cars that are locked up over the winter and only blasted (and i mean blasted)every other weekend in the summer dry up and all the oil drains into the sump cos they arent started that often and when they are, they are abused, but where cars used regularly always have some sort of lubrication around the engine? i have been told that oil takes a while to circulate around these engines and better off used regularly
