i have a 98 voyager van v 6 3.0 and it overheated. the thermostat sensor made the fan not kick on. and then there was water and white smoke coming out of the tail pipe. not a little, it was alot. there was also pressure bubbles in the radiator. there was no water in the oil at all. the van sounded perfect. no missing no nothing. after we got the fan working it was perfect except the white smoke and water/coolant in the tail pipe and the bubbles in the radiator. so i had a mechanic come over and he changed the head gaskets. there was evidence of burnt coolant where the gaskets were on all six cylinders and the valves not just one. he said that was odd because there was not water in the head itself. the mechanic said normally it would be clear where water had gotten into the head and that it would have been washed clean by the hot water pushing through but it was covered in oil and there was no water at all inside. he was confused because it didn’t explain the tail pipe situation. there was no evidence on the head that it had been cracked. the block looked fine too.but he couldn’t promise it wasn’t cracked without sending it to the machine shop. keep in mind the head had no water what so ever in it. so we decided maybe we couldn’t see the leak in the gaskets and went ahead and put the new gaskets back on and put it all back together. well nothing changed, there was still pressure in the radiator and coolant still in the tailpipe. i don’t know….. neither did he… we are going to change the whole heads next. should i. am i missing something? have you ever heard of something like this. this is getting expensive and i cant afford to make another mistake. please help. the mechanic is going to think on it but he said this is a first for him and he owns a shop. so no water in the oil no water in the heads but evidence of residue on the gasket on all six cylinders and all six valves. white smoke and water in tail pipe . air pressure getting into the radiator. all the while the van sounds great. what is the deal……

yes this is a nice vehicle and i need it. i cant afford another one and i have 4 kids i need a big car. i am hoping that i can find a good used head, for cheap and the labor isnt to bad so i think i shoud fix this car instead of getting into a note that i cant pay right now. you have been very helpful. do you know where i can get a used head at a good price? online maybe. its a plymoth voyager v6 3.0 1998 thanks so much

question??? if the head is bad is it common for both heads to have the coolant residue around all six cylinders. or does just one go out at a time. would one cracked head effect the other. do i need to replace both. it would cost as much to send off as it would to replace one, or i can just buy two new ones. is it worth the extra money to buy new one instead of sending it off?

head gasket blown for sure but head might be damage also don tknow til one removes and has check for sure you need a head gasket
the person that did the work should have known to have the heads checked for cracks, and also have them leveled. anytime aluminum heats they warp.
it,s probably the head gasket leaking. you can,t tell if the head is cracked until you pull the head.
if the iron head , they should be ok just change the gaskets
you should check your piston rings or have a compression test on the engine.that might help!
If the head is cracked , then you will need a new one. It does sound like the head is cracked, but it is confusing that it is happening to both sides. It actually sounds like it could be a leak in the manifold. I would also have the manifold checked as well.
Your mechanic should have tested the radiator for exhaust gases before doing ANYTHING, just to be certain of where the bubbles are coming from. You should also have taken your heads (both of them) to a machine shop, where they would have pressure tested and if needed milled your heads flat again(would cost about $100 and is very important after over-heating). You are most likely going to need new oxygen sensors and catalytic converters if you have been running your vehicle in that condition for a long time(anti-freeze destroys both over time(not much time either)). Honestly this could get a lot more expensive and because you are not working on the car yourself, you could save a lot of time, hassle, and likely money also, just by taking your van to a reputable and licensed service center. Sometimes your auto-insurance will cover it if you go to a licensed mechanic, look into that.
