    have you done a compression test on all the cylinders? if your loosing coolant and there is excessive moisture in the exaust there could be a leak in the head gasket. a compression test could tell you if there is or not.

This looks like you have a blown header gasket. You probably can smell anti-freeze in the exhaust.
You can verify the problem by have a pressure test of the cylinders. At least one will not hold pressure. The cost of the new gaskets is cheap compared to the labor to install them. Every item with a gasket that is removed to get the header off will require a new gasket.
Valve cover gasket$
Intake manifold gasket$
Exhaust manifold gasket$
Header gasket
etc$

If the coolant is getting into the cylinders the exhaust would be white. Look for trails (white or green stains) around the radiator, engine block, and maybe the heater-core. A helpful tool is a pressure tester. If your confident that you have antifreeze in the exhaust then you need a head gasket. Have it repaired ASAP, it will damage the cylinder and piston/s.

Losing alot of oil


have it checked for oil leaks, if there is no oil leaks or small leaks that won`t justify the amount of oil your losing then you engine is burning the oil. it could be stuck oil rings. there is chemicals that you can add to the oil to see if they will free up and stop burning oil. just because you don`t see a lot of smoke out the tailpipe doesn`t mean its not burning oil. another thing to check is the PCV valve as if it isn`t working properly can cause oil burning as well.

Water coming out exhaust


If you are losing coolant out the exhaust, the exhaust will have a sickly sweet smell as opposed to the normal stench. Otherwise, a small amount a water dripping from an exhaust pipe is not unusual, as moisture from condensation can build up inside the muffler when driving short trips; this moisture is expelled while driving. If you are not losing coolant, then this is probably what you are seeing and it is not a problem.

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.

I have a 1990 chevy beretta with a 3.1 and im having trouble with it losing coolant and overheating it dosent seem to be any gaskets but i cant tell where the leak is coming from i do know that the coolant...


there are some coolant heater hoses right above the exhaust manifolds check those, also check engine oil for discoloration due to coolant contamination. may have moisture on dipstick, oil may look like a chocolate shake texture. if so then most likely internal intake gasket leakage.the best way to check for hose leakage is to pressure test the coolant system if possible.

Smokes when you start up and then stops


didn t say what color smoke --if you start up on cold or damp days and get a small white or steam looking discharge from tail pipe than your burning out/off the moisture that has accumulated in the exhaust system when all moisture gone smoke gone ---white alot- billowy-and doesnt stop burning coolant -water/anti-freeze-leak in coolant or the famous blown head gasket ----black smoke and not a diesel carbon build up and or need tuneup---blue smoke burning oil something in engine is damaged and allowing oil into cylinder and is being burnt

Alot of white smoke coming out of exhaust


If you are also losing coolant it is likely a blown exhaust gasket. The white smoke is a result of coolant leaking through the exhaust gasket and and being forced out your tailpipe. You can check to see if the head gasket is blown by removing your oil fill cap and checking the oil for a milky brown color. I hope this was helpful.

The leaks is likely running down from a higher spot like under the A/C compressor bracket. Check all 4 corners of the intake manifold for leaks. This a common leak.
