That goes a long way to demystify the Speed Six internals. I wonder if it’s possible to remove that front timing chain cover to allow the change of the water pump with the engine still in the car. That pesky harmonic balancer would be the problem I think. Would you be able to show us the half time bearing please and what to look out for? Is your next video going to be on checking the timing? Just on the head, was there anything to mention about the valve guides and stem seals?
I think the cover can come in the car, I remember reading something in a TVRCC article about it but you had to jack the engine up slightly to clear some bolts. I assume then removing the oil tank would mean you'd have done access for a puller aswell. I'll put some bits in the next video but the half time bearing is a simple checking for play with the tensioners not erm tensioned. The timing all I did was find TDC on 1 and 6 then check the two flats on the cams line up. It wasn't too detailed as the engines run before and to go into cam timing you need a large timing wheel which I haven't got. There is some bits on the valve stems in the next one too🙂.
I don't actually know what you mean sorry? I saw a post about the grooved main bearings being fitted which you've seen but then I can't believe that's a mod as they are standard rover V8 bearings. I did read a post on Piston heads from Dom at Tvr Power stating that they're rebuilds are standard oil wise, they just use quality parts. That was from 2009 mind. What was it you're referring too?
That’s ok I just thought from the forums that people had rebuilds in the early days for poor oil distribution and that the engine rebuilders did something to the oilways to improve the situation. Graham Varley mentions at the end of that workshop manual something about the later speed six having improved castings for this. If you haven’t spotted obvious in the head then perhaps the early issues were just related to poor finger follower quality and not oil distribution. I’m always keen to keep an eye on oil pressure with my car and there is such a variation between hot and cold idle. 70 cold and 15 when really hot. Looking forward to the next video!
It's great to see some detail on these engines. Thank you

One more ask if possible please. Could you please show us the oiling mods that were done to the SP6?
