Re: 94 GMC sonoma needs head gasket
No real pit falls just drain coolant remove head have head checked at machine shop. Clean engine surface good and rise good with brake clean, make sure head gasket is on correct before head goes on bolt down with proper torque and sequence then finish up then drain oil.

Oil in the coolant is usually an intake manifold gasket problem on these engines. If a head gasket failure the engine will normally overheat and give erratic temp guage readings. Make sure the oil level is full. Is the rattle noise coming from the engine? Some times the exhaust (converter) will fail and the catylist will seperate causing a rattle noise from the exhaust and plug it up giving a no power situation
your leak is likely in head leaking into the spark plug ignition area and burning of once vehicle is running check plugs for moisture before motor is hot, also can seal using blue rhino at auto zone I used on 6 vehicles and sealed all of them.
Is the passenger side floorboard damp at all? When you put the defrost on do you smell antifreeze real bad? Windows fog? This would be a sign of a heater core going bad. A lower intake could have a leak too. Sometimes they leak slow and not all over so to speak. This can also cause a sweet smell in the cabin as well. Since you said the oil looks good we can leave out a cracked head, cracked block or bad head gasket.
its not hard, but you need the right tools, procedures, you need to know what you are doing. You also need to repair why the head gasket is blown. You will need the head checked out at a machine shop, it may be warped.
could have a blown head gasket or cracked head or worse case scenario, a cracked block letting oil into the combustion chamber and out the exhaust. if it is letting coolant into the oil then pull the dipstick and there should be a milky white look to it where the oil tried to mix with the coolant. but its normal to have water alone drip from the drain hole in the exhaust from condesation. for every gallon of fuel your vehicle uses, it produces about a gallon of water thru the exhaust
On the side of te head above the # 3 spark plug check to see if ou have a frost lug there in the head, Also check if there are any heater hoses in this area to be sure that they are not spraying antifreeze from a pin hole. Before you go and buy a new or used head be sure that the head is the actual problem, it could be as simple as a head gasket. Also check to see if you have white smoke coming out of your exhaust as this is a tell tail sign of a head gasket.
