Doesnt really matter when it happened, does it?
Take the head off and make sure what is cracked. Maybe youll get lucky and all you will need is a new head. I suggest if a new cylinder is required then you also get a new piston and rings and have the cylinder bored to fit for best reliability and performance.

It is important too identify the following:
1) The source of the exhaust leak
2) The source of the oil leak.
The exhaust leak could turn out to be a bad exhaust gasket, a cracked or loose exhaust manifold, a cracked cylinder head or bad gasket, or related parts. The oil leak could turn out to be the valve cover gasket. A dried out valve cover gasket can cause oil to sit on the spark plugs and have oil leaks. Be sure not to over-fill the oil. A machine shop can find cracks in cylinder heads. If these problems turn out to be ok (and one of those stethoscopes may be helpful) then you could procede to check fuel delivery. (there will be pressure in the lines) A lot of times connectors get corroded. I noticed on this model the sensor for the engine cooling mounted near the thermostat is very sensitive to variation. Same for the air sensors if left loose.

What is wrong with my 2004 chevolet malibu, its leaking oil tremendously

If this has the v6, it's probably the intake manifold gaskets. This is a super common problem with these. You end getting oil in the cooling system and anti-freeze in the oil, they also leak externally when this happens. I would get it looked at/repaired asap or severe engine damage will result. I've had to replace quite a few over the years.

Oil in water redatoer

I don't know what kind of Chrysler product you have but if the oil is red/pink you probably have a crack in the transmission cooler. If the oil in the radiator is gray you probably have a serious engine problem like a bad head gasket or crack in the block or head.

Oil pressur low

I have just cured my low oil pressure (and leaks) by using a stop a leek additive from e-bay. LUCAS engine oil stop a leak. £14.99($22 approx)
It takes a while too get it in the engine as it is extremely thick, but works very well. It evens stopped the slight noise from the oil pump.

My car is misfiring in 4 cilinders and it lost power some times

Check the ignition timing. Check the cables for leaking voltage through cracks in the insulation, or check for very high resistance. Check the distributor for cracks.

This was happening with mine - leaving trails of water behind as well when I ironed. I took it all apart (figured it was already broken, what could I do worse?) I discovered that there is a rubber gasket around the hole that lets water move from the reservoir to the heating plate. The two surfaces (reservoir and plate) are held together by screws, which compresses and seals the gasket. The bottom surface of the reservoir section had been cracked (due to a drop on the cement floor, probably, and the two surfaces could no longer fit tightly together, the crack allowed it to flex, and water leak out. In other word, once it's leaking like that, it's time for a new iron. Sorry I can't offer a fix, but at least a explanation!
