I have an 88 Grand Voyager with the Mitsu 3.0L V6. Last summer I replaced the heads on it, but I had the Distributer off by 1 tooth and it overheated. I fixed it and it ran fine for 9 months. Then all of a sudden it has lots of coolant in the exhaust. I put in new head gaskets but it is doing the exact same thing. I do not see any exhaust in the coolant, nor do I see any coolant in the oil.
Could it be a cracked or warped head? Would a problem like that come on all of a sudden?
The body of the van and everything else is in great condition. I don't want to trash it for something that I may be able to fix realatively easilly. As you can tell I don't mind tearing into the engine.
Any ideas?
