Evening all,
After a managing to get a few hours in on the car today, I decided to have a go at the awful bonnet alignment and I mean awful, were talking out by inches and wagglier than a waggly thing, I think neil who had the car previously must have popped it back on quick and added the alignment of it to his 'to-do' list... I now understand why he left it on the list !
So after quite a few hours of fettling and head scratching I've managed to get the bonnet a lot better. The lines, height etc are not far off just need a bit more tweaking, but... the damn thing is fouling the Idle Speed Control Valve, not by much, a 3/16 of an inch (ish) I reckon
I think I could gain a little bit of clearance back buy removing some of the material around where the wire mesh of the bonnet vent is fixed as this looks a bit, well, clumpy, but I doubt that this on its own will be enough. I could file the ISCV a bit but I'm not sure that's a wise idea.
This being my first 'S' and not actually having seen a well fitting bonnet before, has anybody come across this before? any ideas on a fix, tweak, fettle, prayer... anything
The engine mounts have been replaced very recently but the looks of them and there is plenty of room between the sump and the ARB so the situation will improve as the mounts relax and squish a bit
Apart from the fouling it's not looking to bad, sitting a bit high windscreen end (due to the fouling) but if it didn't foul it would pretty close. I don't have any bonnet pins to try, but a marker bluetacked into the hole and masking tape over the latches showed them to be almost spot on
Any ideas gratefully received

Just a thought, when the engine mounts were replaced, was the engine left slightly canted over to one side?
You could slacken the mounts a little & carefully twist the engine to a position where the ISCV no longer fouls.
Good luck Marc.
Ohhhh I was really hoping nobody was going to mention this, as I have a sneaky feeling that this is the root of the problemYou could slacken the mounts a little & carefully twist the engine to a position where the ISCV no longer fouls.
Good luck Marc.
So what's the procedure, I'm assuming its, loosen the engine mounts and jack on the near side of the engine (not sure where's best?) and try a wiggle it down a touch on the drivers side
Many thanks to all
Thanks for the replies...
I managed to move the engine a bit, which has given me just enough clearance for the bonnet, but it is still damn close. If anybody is thinking of changing their engine mounts check the levels for clearance before and after so you can get it right before putting everything back together again, luckily I had the manifolds, exhaust and various other bits off anyway which improved access and leverage but I imagine with the engine all in place and ready to go it would be a right royal PITA
Looking at it now I think that part of the problem is the hinges, the are old, worn and a bit bent. I know (i.e. looked at old posts) that Gerald-TVR used to be the 'go to' man for these things but his on a TVR sabbatical, so where are people sourcing shiny hinges from now (I don't have the skills to fabricate them from scratch) failing that, does anybody who fitted a set of new shiny hinges have a half decent pair of original hinges they're prepared to move on
This bonnet tweaking lark is quite addictive! spent ages today trying to line one tiny little bit even though there is a pile of other jobs I could be doing, and had a great time doing it. It looked good until I opened and closed the bonnet a couple of times

stupid question: is it the bonnet or alignment and a dropped heat shield under the bonnet?
No heat shield under there, shuffling the engine on the mounts gave me just enough clearance to close the bonnet without fouling, but the alignment is being hampered by the hinges which are worn, sloppy and a both a bit bent Gassing Station | S Series | Top of Page | What's New | My Stuff
