Mercury villager 2000 Rough idle white smoke

Unread post by prorig » Sat Mar 30, 2013 2:42 pm

Now that I got my van to start again an old problem that hadn't showed it ugly head until I cleaned and repaired oil leaks and cleaned trottle body. When starting in cold weather it idles rough and exhaust is white also a very bad oder is present from the looks of it I have a coolent leak I determined that it could be one of these bad head gasket , cracked head or egr spacer plate how do I pin point the problem ? Noticed that intake manifold and egr ports had more than just light carbon when cleaned.

If you're blowing white smoke out of the exhaust, that means you're burning coolant, so the most likely problem you're facing is a blown head gasket. A leakdown tester would come in handy to find out for sure, but not many people have access to one. If the engine has a lot of miles on it, or if it's been poorly maintained, you might not want to put any money into it. A big repair like replacing head gaskets can lead to a bottom end failure on old, worn out engines.
