I have a 1984 e28 520i with 220.000 kms and I have problem with the
number five cyl.
When I take out the the spark, this it is covered with oil.
The CO2 reading of the car is 1,4 % and the HC is 450 ppm.
The compression of the cyl. is 150 psi and the others cyls. is betwen
175 and 180 psi.

Any of you have a similar problem? what happen?
Is the rings? What can I do without overhaul? A ring change?

I only use a Liqui Moly oil and change it each 5000 kms.

Regards, and sorry for my English, I live in Chile...

9 out of 10 it's the head gasket, but in the same time check carefully the
cylinder head...

good luck

1.- Revisa regulación de válvulas. Sería el ideal que perdieras compresión
solo por eso.
2.- Antes de medir la compresión echa una gota de aceite en el cilindro que
está con problemas. Si sube, son los anillos.
3.- Podrían ser también los retenes de válvula pero lo dudo.

Suerte y cuenta cómo te fue.
