Hello all. I am having a problem with my audi exhaustingthick white smoke. I noticed the vacuum hose was not intact (if it makes a difference) and reconnected it (after smoke problem). AlsoI am having a"gargling" noise and also an oil leak from the exhaust. I am thinking that I have blown a head gasket. I just bought a replacement head gasket set with bolts(http://cgi.ebay.com/ebaymotors/Audi-...spagenameZWDVW). I have read other posts and done my own research to find that white smoke is either water orcoolant burning with the gas.Other than the smoke I noticedmultiple oil splotches on my turbo and downpipe. Does this sound like anything otherthan a blown head gasket?Please help me out if you guys have any info. Thanks.
