1994 Touring, upon cold start up, after about 5 minutes exhaust starts comming from the turbo area under hood. Don't really notice unless the hood is up, but then it is obvious that something is not as it should be. After another 5-15 minutes its gone!! Seems to run OK, have not yet gotten close enought to pinpoint location. Car has 80k, Mazda installed engine has 20K (by previous owner) Stock, probably has original cats. Any ideas??

gasket between downpipe and turbos blown? o2 sensor loose? manifold between turbos and block cracked? that gasket blown?

Could be the rubber coupler at the Y-pipe area (the pipe that comes in and down from the IC). I had that coupler take a dump on me and it was leaking oil, etc. and it was a headache. I replaced the part and it's all better now.
