I've got a 2.3 manual trans.....I had a misfire for awhile, I replaced the coils, plugs twice, wires three times, fuel filter, cold air intake mass flow air sensor, iac valve, injectors, and the latest is the ecm..... now as I drive it, it's not missing, but its pouring oil into the exhaust system. Its smoking terribly. .... any ideas what's going on or what steps I should take now?

 

What YEAR?

So what engine 2.3l Lima or 2.3l Duratec?

How many miles on the engine?

First check PCV Valve makes sure you are not SUCKING oil in from valve cover/crankcase

Do a compression test, dry and then WET test

If dry is 150-160psi and wet is 160-170psi then Rings are OK you have leaking valve seals

Pull the head and change the valve seals
