I Need Help with my new Z

hello. I am Oscar Moruno from Seville (Spain).
I recently bought a 260x 2 + 2 unit. He burns a lot of oil, spilling unburned oil from the exhaust pipe. I have done a compression test. and the result has been between 170 and 180 PSI in the 6 cylinders.
Can someone give me an idea of why and where is the oil entering the combustion chamber?

because the car runs very badly and ends up wetting the spark plugs in oil.

thank you very much to all

regards

Hi, which plugs are wet with oil? all of them or just one or two?

I would say that at least 4. the car right now I'm only moving it to put it in and out of the workshop. but when I have it started for about 20 minutes it ends up starting to fail until it stops.
then I take out and clean the spark plugs and go back to starting relatively well

Are you really sure it’s burning oil??
If it’s spitting out the exhaust and wetting the plugs are you sure it’s not unburnt fuel ? That much oil entering the combustion chamber it would Be smoking like a Trabant .

Yes. It is burnt oil. It smells like burning oil, the smoke is very dense, and it smokes very much. The more the engine heats up, the more smoke comes out of the exhaust pipe. Even the exhaust pipe drips unburned oil. It is very scandalous.
