    The chap i'm working with sprayed wd40 into both ends of the ht leads and into where they connect to the top of the ignition coil.
    This sounds pretty bad to me but i'm no expert so does anyone know if it is bad. I did a bit of googleing and I think wd40 is an insulator and over time it get becomes more of an insulato,Any ideas on how to clean it off.

    WD40 displaces moisture.

    leaving an electrically non-conductive barrier
    Isn't this bad?

    If your concerned you can always clean them yourself. You can get electrical contact cleaner which I would say would have been better.

    Well I dont know the science but Ive often used it on old swithes etc to get them working again and never had a problem. It says on the can that it can be used on electrical contacts. I wouldnt use it on super sensitive electronics though.

    I used to do it back on the day, but I'd wipe them (cap and leads) down afterward.

    The only downside I would see is that the oily residue would encourage dust, and ergo tracking. Wiping off the excess seemed to help.

    In fairness, most engines now are practically enclosed anyway, so the days of water getting fecked up onto the head of the engine are rare.

    Stop worrying cork, wd40 might insulate low voltage, but it wont impede the high tension system. I've used it for years on motorbike ht leads to displace moisture, works great. I've actually rode a bike through floodwater several times where the leads were submerged.
