One other thing i meant to mention was:
The car was driving fine, has been using oil or water and reasonably economic until one evening she through up the engine management light and completely died. Felt like a mis fire and after i through it onto dignostics came up misfire on 2,4,6. I went for a wee hoak, pulled the sparks from 135 to find the had a bit of oil on them, pulled 246 out and they were completly soaked in oil and oil had created a pool inside the plug well. all were oil except for 6 which was oil and water more water than oil tbh. Cleaned it out n replaced sparks n that solved it but from then she drives fine but now hittin 90 n fan having to come on to drop her away down again but not under hard driving just general 30 -40 n now a nice cloud of white smoke following me everywhere. I was thinking cam cover gaskets for the oil but now wondering are the heads starting with her over heatin n blowing smoke. water level hasn't dropped very much. half a mill maybe n the tiniest amount of mayo on the oil cap which i thought was maybe just a tiny bit on condensation. Any ideas? Am i on the right track or is there any else i need to check for.
Thanks
