hi guys

ive got a 85 series 4 turbo

ok, the other day i noticed that my oil pressure gauge was acting very eratic (would go from 60psi to 0 when at same revs). i suspected the pressure sender so i replaced it with a new one. now the pressure sits at around 100psi at idle then as i start to rev it then pressure drops right down.

any ideas?

dam rotarys lol

cheers

 

Its its not your oil pressure sending unit you have a bad pump or bearing.
