Question about Cars & Trucks
All filters and oil changed,
I think you have a blown engine cylinder head gasket or gaskets and or a cracked cylinder head or heads. Any qualified auto tech can confirm this guess is the the problem. Do not attempt any repairs until a shop has looked into the problem.

I had the same problem. I changed the pcv valve and checked the hose. It still did the same thing. Then I checked the metal tubing that the hose connects to and found it was full of hardened gunk. I sprayed PB Blaster into the tube let it soak for awhile. Then took an old choke cable, put it on a drill and ran it into the tube like a drain snake. It took a while of doing this over and over but eventually got it cleared out. Now, no more oil all over the engine and hood compartment.

You need to check for engine codes to see what is wrong. Bring it to a parts store for a free scan for codes. The check engine light indicates a problem, probably the emissions system, which is causing the poor performance. The parts store will plug a hand held scan tool into the cars diagnostic port (usually located under the dash) and 'read' any codes stored in the cars computer. They can them tell you what code #'s come up, what they mean, and how to correct the problem. If you have any questions after that, post them here w/ the code #;s for further help.

seems like the engine isn't timed right, either the timing marks aren't lined up or if there is a distributor it isn't in time with the crank and cam

The most common cause of blue exhaust smoke is oil leaking past engine seals and into the cylinders where it then mixes and burns with the fuel. This is most frequently seen in older or high mileage cars with worn seals and gaskets. It only requires a very small amount of oil leaking into the cylinders to cause excessive blue exhaust smoke.
Blue exhaust smoke only at start-up can indicate worn piston seals or damaged or worn valve guides which may also cause a rattling noise. An external engine oil leak can drip onto hot engine and exhaust parts causing what appears to be blue exhaust smoke. Other possible causes of blue exhaust smoke include: piston wear, worn valve seals, a dirty or non-functioning PCV valve, worn piston rings, an intake manifold gasket leak, worn engine oil seals and possibly even head gasket failure.
Oil leaking into the cylinders can cause a rough idle, misfire and fouled spark plugs. In addition, a reduction in power and oil loss can be indicators that the blue exhaust smoke is caused by an internal engine oil leak. Internal engine oil leaks can also allow fuel to mix with the oil in the crankcase which will degrade the oil and prevent it from adequately protecting the engine.
Operating a car with a severely dirty oil filter, air filter or improperly functioning PCV valve can also sometimes result in engine oil blow-by, oil loss and blue exhaust smoke. Periodically checking the engine oil level with the oil dip stick will indicate if there is excessive oil consumption. Higher viscosity engine oil can sometimes temporarily reduce the amount of blow-by; however, this is not generally recommended. Excessive blue exhaust smoke indicates a possible internal engine oil leak that should be inspected by an ASE certified mechanic.

i believe the engine is running too lean as if it was running too rich it would blow black smoke If it was blue smoke it is oil related eg valve stem seals,valve guides and or piston rings all of these things will create blue smoke if one of the above is worn out
