Yes the s6 did have many faults and some which didn,t make it the customers ,like the cam shaft that fell in half on road test on me at x amount of revs ,a bad batch resulting in 24 engines stripped down and re built. After i left the lads at the end said it was like a different engine with most of the problems ironed out.
I think its great to have someone like yourself on pistonheads who knows more than any of us when it comes to TVR.
In which year did the factory iron out the S6 problems. Might be worth knowing to someone who is thinking of buying a S6 car.

I am by no means an expert when it came to the s6 engine that would be your JR, SH and Minnsy..Soon after i left Wheeler sold up and the engines then still had problems with poor quality parts ie India.The finger follower problem had more or less gone away..Some of the units did tend to have a breather problem and would whislte like a kettle when you came off the throttle. some of the engines have a valve fitted at the back of the rocker cover to correct this .As in the previous thread there seems to be a debate about warming up the motor before full throttle this was nothing compared to starting up the motor for the first time .The engine had to be primed by hand pump from a 40 gallon drum this ment disconnecting various pipes messy and a ball ake.As the cars were built on different lines not all would follow this method tut tut .Talking to the lads the engine did improve greatly under the new owner which might not go down to well in some quaters.This was mainly down to better internal parts and when your making fewer cars more time and care can be taken.
When the s6 first came on stream a large number of engines was required in a short period of time some 20 plus a week every week at first .As all could not be put together on site TVR power would also send partly built units to make up the numbers and then dressed in the engine shop.This may not go down to well but many of these engines gave us problems plus with the quality of some of the internals parts just compounded the situation and then when the re-builds started to pile up the strain of purchasing parts and man power started to tell.The best blokes in the engine shop would be spending more time with the re-builds so you relied more on power to make the numbers up and so the cycle began .It was not all powers fault as it was a learning curve all round .Bolting together a s6 isn,t quit the same as the good old rover unit which they did superbly.In the end when less cars were being sold and less engines required they were built back on site and with the lads putting their initials on the block a brave move, there was more accountability and control of the product.I can't emphasise enough the strain on the lack of parts caused by re-builds.If you could only get enough parts to say build 20 engines a week but half was required for re builds you could only build 10 complete cars for delivery so your cash flow dropped but you needed more money for more parts with less cash generated and so on.
That's how I understood events unfolding. I also suspect that the strain this caused everywhere distracted from standing back and taking a long hard look at the S6, the priority instead being to get engines out any which way.
Are parts from a 2005 engine interchangeable with parts from a 1999 engine?

That i could not say, what went on in the engine shop was kept on a need to know basis but if RE work is still on line he may be able to shed some light on that one as after i left he the went into engine build .

Mex - did TVR make any specific mods to the engine or simply tighten up quality control on components (and assemble said parts better)?
The parts which were of inferior quality were sourced at the insistance of a Purchasing Director. It was a case of gross incompetance and in reality the items cost more abroad than they would have done is the UK. A particular example was such; cranshaft casting were purchased in the UK, shipped to India for machining, shipped back to the UK for heat treatment, shipped back to India for final finishing and then shipped back to the UK for assembly.
The usage of inferior parts came to a halt when the Director left.

Thats exactly how I remember things being the last time I visited. There was a huge industrial skip full of speed six engine parts, blocks etc. Danielle asked me not to take pictures and I remember thinking "eek I've just ordered another one of these"
It stands to reason that if so much time was spent sorting rebuilds new orders would suffer.
