Hi everybody its been a while

I'm having an issue with my vectra B z22se with the power steering it's just throwing fluid out of the pot just wondering if anyone has used the repair kit on the rack on one as think it's a popped seal? Also is the timing reference code just a code that stays on the ECU because I've replaced my coil pack for a Delphi one and that code stays there it's under monitors but when I read codes it's there but wont switch off but mel isn't on because of it
If you don't have a live/active code for coil pack don't worry.
some code readers don't clear all codes.
what carl said on FB, pipe squashed could cause problem?
