water in exhaust

[mouse777]

Hi folks, New to this forum and my 91 Exployer, 4.0. My winter project has water out the exhaust. None in combustion chamber or oil. Compresion is 140 to 155. 130k on engine. I'm thinking a cracked head. Anybody thinking somthing better? Thanks in advance.

How much water? Water is a normal product of combustion and will often condense and drip out of the exhaust when the exhaust is cold.

Agreed when the truck is comming up to full opperating temp it is normal for there to be some water dripping out with some white 'smoke' its actually more like fog then smoke though

Thanks guy's, but I'm talking white smoke and water level drops. I'm just hoping for an easier fix.

 

[MrShorty]

"...water level drops" as in you're losing coolant? Now it's starting to sound suspiciously like a cracked head/blown head gasket, though coolant can get into the combustion chamber through the intake manifold gasket, too. Any coolant in the oil or oil in the coolant?

 

[mouse777]

No Mrshorty, plugs look normal, no water in oil, or oil in water. If intake leaked it should show on the plugs I believe. But that still sounds better than a head. I'll be there first when I get into it though. Thanx, mouse.

You guys I would check the radiator, radiator cap, and the heater core WAY before I start replacing a cracked head.

Agree....Always start with the easier solutions first.

However the early explorers were known for bad head gaskets if I remember correctly. Just because you don't see water in the oil doesn't rule out a head gasket competely. The water could be getting burnt without you seeing any in the oil.

I had the same problem with my 91 EX with 300K mi on it. I have an engine I am waiting to put in it to really correct the problem but ...I used two bottles of Bars Leak and it worked great! I know I still have a bad head or head gasket but it stopped the cloud of water in the exhaust and the loss of coolant.

I didn't think there was water in the oil either but when I removed the valve covers I could see that it was gummy from the water.
