Seems like it - or stick to a 3.5 which some experts also say are not worth reconning best to go for a 3.9 or 4.2 I think my 3.5 will see me out Phil just turned over 40k Sorry Richard Proboards had a problem

So in effect Alan if you have a Damper or Flexplate or Torque Converter "change" you would have a problem on a 3.9 and 4.2? it would be a matter of removing the engine to have it all re-balanced? Anyway I am glad you are sorted Spot on John. Change any of the components and either the whole lot needs balancing as a whole or all of the individual components. But only on a 3.9 or 4.2 engine. Any other variant is apparently OK. In hindsight I wish I had rebuilt my 3.5 BUT I listened to 'professional advice'. I may yet rebuild the 3.5 as a project so the original engine can go back in.

Some of it did Harvey.
Anyway, fluids all filled and started up this afternoon. Running smoothly.
Tickover is high at 1200 as it warmed up and there is a small leak from pipe from the back of the inlet manifold.
Now drinking tea waiting for t to cool down so I can deal with the leak.
Oil pressure remains for well over 20 secs after engine stops.
Can't test drive as no MOT but looking good

Good news Alan. Good you have solved this issue. It has been a lot of work for just eliminating a vibration but now you will really enjoy the Rover again.

Thanks all.
Leak cured with a small manipulation of the hose and a worrying moment when I tried to engage gears and had no drive was cured by adding more gearbox ATF.
The real test will be when I can take Benny for a spin but until I get an MOT a small worry will remain.

MOT obtained!
Tester spotted that one of the front brake unions was just fouling a shocker on full lock - now adjusted.
Engine pulls well and is reasonably smooth. Not as silky as I thought it might be.
Had to reset the tickover but otherwise all good.
Now a wash and brush up ready for the P6 National Tomorrow as a test run.

I think it all needs to settle down - so well done so far. Even Rolls Royce V8's are not as smooth as the IOE 6's (RR or Rover)

Hmm. After a 120 mile round trip today to the P6 National I think the celebrations are premature. I'll post a full summary later but right now I'm off to celebrate my birthday, my Wedding Anniversary and to drown my sorrow.

Update: The vibration is very much as was so the balancing has made no difference.
I spoke to John Eales yesterday at J.E. Developments and explained all that I have done to try and resolve the issue. He is stumped as well.
I think the next option is to run the engine out of the car on a test bed and see what happens. Check all set ups one by one. I have kept the old subframe which could be used as the mounting frame.
Meantime I will try and take the car to John Eales early next week so he can experience the delights for himself and see if he has any ideas.
ETA: Also spoken to Rob at V8D this mornng - also lost for ideas but invited me to take it over for him to experience the problem.
As it looks like redundancy looms it seems I might just have the time to do that soon.

I know we've had our "online" differences, but I'm sorry that the problem hasn't been resolved because you have put a huge amount of time & effort into trying to get it sorted.

That really is unfortunate news after all of your efforts. Given that the engine was fully balanced this time, I still tend to believe it's the torque convertor. The torque convertor is an add on after the engine is balanced. Even if you've replaced it with a reconditioned unit not all are re-balanced after a rebuild. Often they are just marked before disassembly and then re-welded. I've been through this scenario and the cause of the imbalance was the torque convertor. I can't possibly see that it's anything else given the engine has been checked and assembled by 'experts' (unfortunate term) on 2 occasions now. If it's been on a balancing machine, I can't see how it could be anything other than something added to the package afterwards?

IIRC right at the very start of the thread it was run with the converter disconnected with no improvement.

Harvey, Could have been that both were unbalanced at that stage and that now its "only" the converter?
Alan I wish you strength with everything. It never rains but it pours...but the sun always shines in the end!!

Harvey, Could have been that both were unbalanced at that stage and that now its "only" the converter? I can't argue with your use of the word "could", but I think it's clutching at straws. That said, it's easy enough to check again. The problem with your hypothesis is that to continue along that train of thought means that everything that was checked before the recent balance now needs checking again.

Not running on eight cylinders correctly! put the engine on a diagnostic machine and look at the spark wave form, it will reveal all. I would have started there, taking the engine apart seems a masochistic ( a willingness or tendency to subject oneself to unpleasant or trying experiences)but it takes all sorts. But again thinking about it, this long thread would have not existed so please keep on trying to fix your problem by guessing and posting on here what you do. I'm enjoying reading about all your hard work. Have you thought of meditation for your engines solution? LOL
