Plug extender alternative?
Discussion
Pull the leads and shrouds off and inspect them for scorching or burning. If the socks are good quality they wont be burning! If they have been contaminated with oil they will smoke with the heat.
It could be that the exhaust manifold gaskets have splits in them allowing exhaust gas to escape which might give the impression of smoke. The manifold gaskets do fail especially as the nuts or bolts holding them work loose with the hot and cold cycles of heat. You could try tightening them up to see if any are loose but the gasket may still be split or perished.

Thx for the manfoild tip but this smoke wasnt there before the plug wire change and it s clearly going out of the sockets+boots.It could be that the exhaust manifold gaskets have splits in them allowing exhaust gas to escape which might give the impression of smoke.

So you didnt had any smoke or smell at first startup after installing everything? The seller say it s lava rock and 2000deg celcius resistant...
When considering the visible signs of heat damage on these socks there are two distinct types of damage. Firstly bleaching of the colour, this is not evidence of the socks failing to work as heat shields, it is simply bleaching of the pigment used to colour the socks. Secondly the socks may start to bulge, this definitely indicates heat damage to the fabric of the sock and will eventually lead to failure of the heat resistance.
I have also seen dark brown / black staining, this could be exhaust gasses leaking from the manifold gaskets

It really dont seams to have suffer from heat. I took the plug wire out a few sec after cutting the engine and the msd boot seems at 60celsius the wire msd connector itself maybe 40!

Rather than start a new thread I thought I'd resurect this one. My extenders are causing missfires, tested without and the Griff runs well, so going to dump the extenders. Now I need some heat resitant sleeves, any recomendations? I see I can buy loads from China on ebay, anything from £10-£30 a set, would rather buy some that work, any ideas?
Hi, I bought some Vulcan Titanium Lava Boots from the US last year, and they’ve been great.
Rated at giving protection for plug leads in excess of 2000 deg F - 1100 deg C.
I found one was resting directly on the exhaust manifold, without damage to the lead.
Cost about £85.00 including delivery and a year on still looking like new!

The Chinese socks I bought a few years ago, when my extenders broke (6 in 6 months), were fine.
I moved to ceramic capped leads, runs so much better.
If you delete the extenders, ensure you have something resistive in the ignition - plugs with an R in the code will do
Out of interest why do I need resitive plugs? I moved to ceramic capped leads, runs so much better.

The angled leads seem to be the best idea, they move the boot away from the manifolds.
This chap made me a set when I went over to Megasquirt, they are very good quality with silicone ends rather than rubber.
You can buy all the stuff from him to make yourself, add a crimp tool to that and you can keep stuff in the garage to make a new one easily should you need to.
Better than spending over £100 on a set that may break anyway when you try and get them off the plugs.

+1 after advice from another TVR owner at car meet and looking at his lead set up was convinced to do as follows as I was getting shunting at low speeds !
Buy £20 Craddock 4x4 angled head leads fr Classic Range Rover , NGK BPR6ES plugs
Junked the extenders they were arching so prob cause of the shunting !
Junked the heat socks there just not needed IMO and have ran the car for 7K without
Fitted as above been on over 12 months leads are perfect no need for heat socks don’t touch manifold and ran it in summer heat fans running etc done 7K and the are tip top !
It can be in 5th gear at 35mph barely off tickover and pull smoothly away ! , before Changes with £120 magnecor leads ,that melted even with heat socks extenders and heat socks it ran like a pig !

Mr Retro Leads sells top quality components, I switched to making my own leads using his parts a couple of years ago and have never looked back.
Buy yourself a proper crimping tool which are cheap from AliExpress, you can then produce your own great value top quality leads whenever you need them

Another vote for the angled leads from Mr Retro Leads. Been running them for over a year now. Very good quality.This chap made me a set when I went over to Megasquirt, they are very good quality with silicone ends rather than rubber.
