Ok so im back in the shop again , its been like a week so far !

looks like the oil dep's on the rear of the car were not oil its unburnt fuel , which would also explain why it takes the car forever to turn over , which ive been telling them since this all started that the starter was bad !! maybe a bad injector or someshit , theyve opened a puma case w bmw and are working on it once again !

ive also insisted that they replace the entire exhaust from the headers all the back to the mufflers as thats most likely where the burning smell is coming from and they agree ! so hopefully this will be the end of it and maybe i'll be able to get better than 9mpg but i doubt that ! lol

i'll keep you guys posted

NEIL
