Exhaust Leak HELP ME PLEASE

[QuintinSevernak]

I just put a engine in my 1990 ford bronco I started it up and it has a rough idle when it has been running for maybe a minute or two there is whitish smoke that is coming out where the exhaust manifold meets the pipe but none out of the end of the exhaust system. does anyone have any idea what I can try to do to fix the prob? Thank you for you help

​

have checked for vacuume leaks in yr inlet manifold spray so wd40 or somthing that is oily like pentrating oil spray it around the inlet gasket if the idle picks up that is where the leak is white smoke normaly means its to lean ie vacuum leak

Sounds more like some spilled oil inside the manifold.

If it continues, "white" would indicate a water leak...& that's not a good thing. /emoticons/[email protected] 2x" width="20" height="20" />
