im pretty sure my head gasket has gone but since im new to the engine stuff i thought id make sure lol. when driving it i have no power at all when idling it sounds like a tank i removed the plugs to see what would happen when the engine was running and the two in the middle didnt change the tone of the eninge to i expect the problem could lie between there? just some help would be nice or advice would anyone be to tell me where i would be to order a new gasket? thanks joe
