White smoke from exhaust

I will try that. Thanks

 

My vote as well. I would do this before trying the other fixes. To see for sure, pull the spark plugs one at a time and observe them closely, look at what color the deposits are; (these are the most common)
*tan to light black indicates normal,
*black, dry and sooty indicates rich fuel,
*black and oily indicates oil burning,
*white-grayish in color indicates coolant-water.
The last three could also cause gap-bridging if permitted to prolonged use.

 

Sounds like we have the same jeep. Your problem sounds just like mine. I guess I will tear into the engine. I think I can do it all myself. I have not done that type of work since being a kid working at a gas station. I looked at my manual and it does not seem to hard. I wonder if I should just change the gaskets or spend the money and have the heads checked while they are off .................Thanks RM

 

Since my ex is a mechanic, I'd vote with the majority (and from personal experience) bad head gasket, if coolant mixes with oil your looking at, atleast a bottom end rebuild. condensation you will have equal or close to the same amount from both exhaust (providing your running dual exhaust) Definately something you do not want to ignore..

older buick v6 are rather easy to do head gaskets on. Chilton manuals make it so easy even I can do it.
and yes while the heads are off spend the couple bucks and have the piece of mind that they have been professionally checked.

 

Ok, I have taken everyones advice. I pulled the heads yesterday. They are at the machine shop getting resurfaced and checked. All the other stuff stuff is ordered. I will be putting it all back together soon.

Any tip for the reinstall.................thanks

 

White smoke and a milky substance under the valve cover on one side is not normal. If it were normal, you would have it on both sides. You have a bad head gasket or somewhere there is a crack. You really need to get to the bottom of it right away.

 

Make sure that the heads are checked thoroughly. I just found out last week that BOTH of my heads on my 327 were cracked near the exhaust valve on #3 and #6
Check the deck surface of your block while you're there for warpage. A good straight edge and a feeler gauge will work.

 

Funny question, but have you looked at your oil? I mean since you have the heads off, have you looked at your oil in the pan? I do know that coolant in your oil will kill your bottom end in a hurry. They are as easy as everyone says. any questions refer to a manual, or just fire questions out here. good luck

 

I went to the machine shop to pick up my heads and sure enough, one has a crack between the valves on the middle cylinder. Explains it all. I was not getting water in oil, only water in exhaust. The guy said the intake was sucking water from the crack and then it went out of the exhaust. Now he is trying to find me another head.

More $ but at least I found the problem. Now just need the head and reassemble everything. I got all the other stuff already.

 

I have the carb off and it is getting rebuilt and will be installed with a new gasket. I am replacing thermostat, temp sender, oil sender and doing a tune up, oil change than I will start my re wire project.

the machine shop has not called back about the head, getting a little nervous. I hope he can find one. I had to replace my timimg chain cover a while ago and it was heck trying to find one.

 

Im having a hard time finding a head. Any ideas. 1970 Buick V6, 225

 

I am going to check with the machine shop later today. He did not seem to think he could fix it.

I have tried a couple of wrecking yards and no luck. I have a line on one and the guy said he will have it on Monday. He said those heads are almost impossible to find !!!!!!!!!!!!! Im kinda worried. there has to a source out there somewhere.
