Pipe to Where ?
Discussion
Can anyone shed some light on this one or is it just another TVR feature.
Whilst sorting a few odd jobs on my 97 Griff 500 I found a hose on the top of the engine tucked under the plenum intake assembly that was blanked with bolt, it doesn't look right.
The pipe comes from the front of the cylinder inlet casting, just fwd of No1 injector, is about 8 inches long and looks as though it should connect to one of the pair of pipes directly below the throttle butterfly (not the larger one next to the throttle pot) neither of these pipes have anything connected and are both open.
The picture at the bottom of page 45 in the bible clearly shows this pipe connected to the outer of the two. Is this correct for my engine and should these two pipes be open, they look like bleeds to either side of the butterfly.
I haven't been having any noticeable running problems other than the tickover being what I consider a little high, I've never been able to bring it down to much below 1000 rpm and thought this normal.
Cheers,
Simon.

If it's the one I'm thinking of, it's a handy way to bleed the cooling system of air, without the whole swirl pot & big screwdriver rigmarole having to take place. At least according to Steve Howard and Thames Valley Racetech.
Some engines have it, some don't, I was told.
The bolt at the end is held in place with a jubilee clip. To bleed, run the engine until just warm enough to get some pressure into the system. Then gently undo the jubilee clip so that you can unscrew the bolt outwards - it's probably created its own thread in the end of the pipe.
As I said... this is what I was told it was. Knowing this place, someone else may come in with a completely different explaination
