Can anyone diagnose this..

ok.. so recently whenever i drive my car.. especially if its a spirited drive... not bangin gears but just hittin boost .. after i come to a stop.. the car will then smoke like crazy.. coming from the turbo .. also i have been killing antifreeze also.. both problems seem to be related.. i also all of a sudden been gettin too much vacuum.. and i havent removed any lines that would do this. could anyone tell me what this is... some of my friends saying its a BHG.. but the car doesnt smoke thru the exhaust only under the hood. HELP!!

You don't have to smoke out the tail pipe to have a bhg. Bhg can leak internally,externally, into the leak exhaust into the cooling system.....and many more combonations. The sypmtoms you give could be a lot. Without having the car in hand to check things makes it though. Could be blown turbo,bhg,an oil leak, a cooalnt leak,powersteering leak. I'm think when you drive it hard your burning up a residue from a leak. Have you checked all your components that have fluid? Check those. Then do the bhg checks. Then check your turbo. Bascicallt narrow it down. Sorry for the slight ramble and long post I'm multitasking.

Removing vacuum lines wouldn't increase vacuum. A bigger restriction in the intake manifold or piping when when the engine is on the intake stroke increases it.

Wait a minute. Smoke from under the hood?

Where from under the hood? You said the turbo? Where on the turbo?

Don't ever just assume BHG, verify it. Do a compression check on it. A compression tester can be had for about $30 and is easy to use. It is possible that you have a blown turbo and a pin hole in the coolant hose at the back of the head (or elsewhere).
