Does anyone know weather the EA manifold has better or worse distributor clearance compared to the EF one, i have straight gas turbocharge EA motor with EF manifold and cant stop it throwing sparks from top of plugs on cap to the intake manifold?

I found that when i put the EF manifold on mine, the dizzy was easier to get to.

Might be good if someone with the EA/D manifold to measure clearence.

Have you tried some sort of insulation?

sounds like your leads arent properly insulated. Mabey have a look at getting new ones.

they are new leads and they are properly installed, i have an XE dizzy in the car which sits higher than an EA dizzy.

yeah i have, but its pretty tight fit. Hasn't always been a problem just a new problem since i advance the timing up, it has position the lead right under the manifold (allmost touching).

possably because of the XE dizzy being taller. Mabey swap it for an E-series MPFI dizzy.

still think try a nother spark plug /coil lead may be new but some brands a crap bought some new years ago ended up taking them back and went for a different brand.

if you have a xe dissy change the gap to suit the model of car the dizzy cam out of caps on the efi xf-au have a 1.1 gap xe have a 0.8 gap may be to much to jump the gap of the plug.

The dizzy is a complete XE dizzy, cap, rotor and all. And i can't put in a MPFI dizzy i don't run any engine computer on it, which was the whole idea of going to the XE Dizzy, which has mechanical advance.
