Hi, wonder if anyone can help, had alot of trouble with my leads being so close to the manifold , especially number 3 as its even melted through the heat proof sleave and then through the plastic body of the lead, now ive wrapped the manifold and as said put those socks on the leads but is still happening.They are also going very brittle due to the excess heat even after only around 500 miles.Does anyone have any ideas on how i can sort this problem?

Heres a pic below so you get a rough idea.The leads i tend to use are just the bosch ones but wondered if there were any others you could use? or heat proof ones? (please note leads are normally tied together and not loose like this)

 

Ceramic coat the manifold? bit strange its giving off enough ambient heat through all the heat proof stuff to burn through the lead socks

 

You could try these http://www.demon-tweeks.co.uk/Motors...Wire/1471/1914

Sorry, have just realised you posted this in the other room where I replied to also

 

i use to run these, very good imo

how about moving the coil pack to inlet side so leads run straight over the rocker cover

ceramic coating can be quite expensive but does work very well also

has it always been running so hot?

 

These reckon on 400 degrees but look a bit pony
jizz tweeks

 

could you not make a heat shield ? maybe out of that waffle type stuff
think its called cirrus or something like that

 

Why not just use a lead that doesnt sit so close ?

they look very unnecessarily long over the plug

 

Zetec it?

 

I did think about this but Jamsport said they have been known to crack if you do this

 

Thats an idea gus, will look into that.I doesnt really run that hot at all to be honest .More the fact its just the heat from the manifold and the leads are so close, its only number 3 thats a problem to be honest.

 

They are very long and not that sturdy tbh, they are fiesta turbo leads.Do you know of anything shorter that i could use that woulnt sit so high out of the plug.

 

Take the hard plastic covers off the actual spark plug end of the lead (FRST/2i), they will pop off - these are what are making them sit close to the manifold. Fit the lead end onto the plug, fit socks (you can make tuck the sock all the way down into the spark recess) and drill a hole through one of the rs1600i fins and use a small cabe tie to make the lead sit away from the manifold.

I had to do the above and I have had zero problems since.

 

Thanks bomber I will try this tonight. How do you find the actual silicone lead holds up to the heat? Is there any kind of sleave you can put over the actual lead itself that's nice and thin. Or even a tape?

 

i ran the exact same manifold with same leads but the braided sock but i had the manifold coated by zircotec (sp)

Never a single problem

 

Just go into a motor factors and pick a lead !

 

After you've removed the FRST outers, fitted socks, just route the leads over the rocker (drill a tiny hole in a fin and use a cable tie on them if they won't stay in place).

Dead easy and 100% sorted the problem.

 

hmmmm

socks looks familiar

 

^^^ This is interesting as didnt think they held up being coated? is this the same as ceramic coating? these boots you have are the same ones as on mine now .

 

Just done this as you said mate so will see how it goes, its certainly more away from the manifold now just have to see how the silicone part holds up to the heat.
