Hi, I've purchase Lincoln TC 1990 with 5.0 EFI overall in good condition. Firstly everything
was okay. But then I deside to clean fuel injectors. So after I put everything back there is

Might be your valve covers leaking oil that is running onto your hot exhaust.

I've checked them they are clean of oil. It looks like smoke comes from hoses and pipes that attached under upper intake manifold. So when I idle smoke getting worse and it smells and looks like smoke from exhaust, but pcv valve hose is ok.

Check the PCV valve itself for being clogged and see if you can access where exactly the hose that the smoke is coming from is not cracked/connected.
