that honey comb your looking at is from your cat correct? if so, who cares.. unless you have emissions check..you'll probably see an increase in power. =) and the wrench with all that fresh oil on it.. where did that come from? and why are you using a standard wrench on a metric car? lol knock it off less you wanna round your bolts.
ok so let me get this right.. you did a coolant flush and an oil change.. now your car is smoking allot from both sides of the engine bay?
did you use regular or synthetic? can someone please tell me if the tale of using non synthetic oil in a car that previously used synthetic causes gasket leaks? I don't really know if its still true today.
i don't see how a coolant flush + oil change would cause you to get a bhg.. less your engine was so close to the verge of destruction that putting the fresh in just tipped it over the edge..
can you elaborate.. if your getting blue smoke from your turbo, your turbo is leaky m8.. needs rebuilt.
