Ok, so my housemate warped the head of his ca18 - non turbo.. and got a 2nd hand engine of a mate (ca18) and, we have a few dilemas.. first of all, as soon as the battery is connected, the front right headlight comes on and stays on... no key in ignition or anyhting... and suggestions of what this could mean? the engine is turning.. just not kicking over.. (every thing has been checked, and double checked)...
