Blown Head gasket or..?
Can anyone give me some insight into this? I think I blew a head gasket on my way into work this morning. The truck fired right up great (like always), stopped at a gas station for a little petrol, and started the morning commute...Then I noticed a little white smoke coming out the back of the right side of the truck...then more, and finally to the point I couldn't see anything behind me. I pulled over and when the smoke cloud passed over, it sure smelled like coolant. I checked the oil pressure and temperature gauge--everything fine. I shut off the truck to allow the smoke to clear, and when I tried to start it it would only "clunk" once and stop.Towed it back to the house, tried to start it again, and she fired right up. Walked around to the back side and noticed water coming out of the right tail pipe. Shut the truck off, checked the oil, and it looks to be 3 quarts high..Blown head gasket or what?
Thanks

you need to do some presure testing and etc.
Take the plugs out and look at them for rust.
Be careful about turning the engine over water in cyclinder may bend rods.
put compress air into cyclinder
I could be intake gasket ?
You may have to pull a head if you cant find anything around the out side
just quick ideas

Another thing to remember is that if you do have water in your crankcase yout oil will look like chocolate milk. Also check your radiator for oil or chocolate milk in severe cases.

The best fool proof method is to run a cylinder leak test on the engine. You can buy a kit or rent one-it includes a chuck to hook up to a air hose, a air regulator, a air gauge to see how much each cylinder leaks down. What ya do is; take all the spark plugs out, the hook the threaded insert to each cylinder and air it up and look for things. Some things to look for is how long it takes for each cylinder to leak down and some tips: take the oil cap off and the radiator cap off. Listen on each opening. If you hear air comin out of the radiator then you have eather a blown head gasket or other way that the air is goin through the cooling system. If you hear air comin out the oil cap then you have bad rings or bad valve seals. If you hear air comin out the carb. then you have bad intake valves. If you hear air comin out the exhaust pipes then you have bad exhaust valves. A similar way is to run a compression test by blocking the throttle open, while the motor's warm, and checking each cylinder's compression. If there's low compression between 2 clylinders right next to each other then you have a blown head gasket and so on. Hope this helps.
