Not a problem on the lever--
The TVR donk suffers more damage from corrosion etc than any actual usage, Normally we shut it down/choke it to death on
oil each year- basicly squirt
oil down the two front barrels while its running @ around 2500 rpm until its showing blue smoke out back, once the smoke shows we kill it & be ready to stall if necessary in top gear, too much
oil & they will diesel or in worst case scenario run backwards, you dont want that to happen believe me! It happened to me on my old Boss 302 once- never ever again, I didnt realise how many Fugly noises a motor could make.
One broken valve spring & signs of delamination in the cam brgs, along with a stretched timing chain were only problems after five seasons in total on that build- hence my suggestion of four seasons max. Only one outer coil broken ( In two places ), no apparent reason & no other collateral damage so I would suggest that it happened during last race or later. Gotta be lucky sometime.
