Dizzy getting hot!!!

[Savtec]

After doing my conversion, i found a smell like a burning smell coming from the engine bay, i pulled the dizzy off and i notice that it was melted at the bottom, so i took it for a drive (AKA THRASH) then i came back and found that the dizzy was melting and dripping on to my extractors, i did put the heat wrap sheild stuff on it but the plastic just heats up then it fall off, i was thinking about a shield but don't know what material to make it out of, any suggestion. OH yea it's a 4age in a AE71

[Jorrs]

mmmmmmmm do u have a picture of the bay, so can c where it is ?

[EldarO]

well, needless to say, it SHOULDNT be doing that.

sounds very much to me like its shorting out something shocking.

uis it pinging or anything?

Sure the ballast resistor hasnt collapsed?

[30psi 4agte]

i no what you mean m8 !!!! i have melted one before too !

put some heat wrap around your no.1 header and make up a shield for the dizzy if there is room .

stainless or some of that purpose built heat schroud like on the xr6 turbo will do !

[roadsailing]

i have seen this a few times,

does you dizzy have a metal heat shield attatched to it? it should go between the cap and exhaust primary #1 - this will hel you out a lot.

[Cuzzo]

hmmm i will be having the same problem with my turbo manifold sooooo close to it. Any thing else which will stop it melting? Certain metals or should i just take it off an put a CAS on there.(Microtech ecu)

[roadsailing]

ceramic coat the manifold

make sure you dizzy has a heat shield

put another heat shield between the two things

duct some air to the dizzy

[JustCallMeOrlando]

Just make sure it's heat shielded, my dizzy is tucked right next to my turbos and right under the intercooler pipe and thats factory.

I don't think it is electric and the car is running fine it doesn't miss or nothing, i think the extractor must be thinned wall so they produce a shit load of heat. the dizzy doesn't have a heat shield so i might try to make one, here's the pics




You can see where the plactic has dripped on to the extractor, so yea

[BigBadBenny]

savtec,
either ceramic coat the extractors, or heat tape them, I've found that foil stuff pretty bloody useless. and put a heat sheild on your distributor, it's supposed to have one, I can even see the screw holes where it's ment to be.

If you look at the pics there is a small bolt hole visable.There should be a heat sheild bolted through it .

Lack of heat shield would be the main culprit. Fit one.

I have also seen a 4A-GE dizzy MELT, due to the numb nuts backyard installer, who got the cooling system arse about!

heres a good qualityy heat wrap that works, its like a woven fibre - not the most attractive, but i use it on my ma61 to protect my clutch and power steering...works well...is like a canvas colour...

[Savtec]

Thanks fellas i will try to make a new heat shields soon as, i didn't even know there was meant to be a heat shield on it, as it wasn't there when i got it. Thats for ya help Gav
