Couple months ago I bought Volvo 242GT 79' with B23E engine K Jetronic. From the begginig my engine is misfiring: https://youtu.be/5iu2euYFy20

and I found mist of oil in intake manifold(I didn't overfilled it with oil. Crankcase ventilation hose was disconnected, so it could not get there by).
Already I have done:
- Changing the oil and filter
- Replacing the air filter
- Replacing the fuel filter
- Replacement of cables and spark plugs, even twice ...
- Install a new fuel pumps, preliminary and main
- Fitting a new fuel accumulator
- Replace and cleaning the fuel lines and fuel tank
- Checking the pressure in the fuel system according to the Greenbook
- Checking the performance of the fuel system and injectors
- Replace the injectors with new ones
- Checking compression pressure
- Regeneration head
- Replacement of Piston Rings and honing
- Replacement connectiong rods bearings
- Checking and replacing the timing belt
- Checking the timing settings
- Setting ignition
- Checking the the ignition system and ignition coil, Checking oscilloscope waveform Sparks (by induction probe) - Sometimes there by aberrant waveforms, but not so much lest there was no spark. The spark "shoots" at around 12mm when I was testing the coil.
- Re-soldering the whole "computer" (cold solder?)
- Checking patency of the exhaust system
- Cleaning the intake manifold
- Exchange All seals of the suction side
- Checking all vacuum hoses
- Substitution thermoregulation valve - WUR
- Replacing the seals (O-rings) on the valve in the fuel distributor
- Repair additional air valve
- Checking the electrical supply fuel pump
And still no change, my engine is working as before...
Maybe here somebody can help me because I've spent 3 months working on this car without success....
