Good evening guys.
2006 4.2sc.
AMK pump, runs a long time, then exhaust blows.
I've also noticed an oily residue on the compressor body.
I didn't think there was any oil in the system so maybe one of you experts can clarify.
It does rise and lower as it should but is slow.
No warnings on dash.
It did have a fault on the diagnostic that indicated blocked exhaust filter on the pump.
So to rectify that I've just taken it off.
Attached is a video of it running.
Hopefully I may get some help.
Thanks all in advance.

Ps I've tried to upload a video but I'm obviously doing something wrong.
Any ideas please

Try a pump refurb kit it's pretty easy on the L322 piston ring usually just wears out.

Apparently the AMK pump is impossible to do without breaking something.
