The turbo oil drain tube grommet is not so hard once you drop the oil pan .
I managed to damage one tube pretty badly by going at it only from above ~ I chipped and picked away at the old rock hard and degraded grommet then had the devil of a time getting the tube out .
The next one I dropped the lower sump and easily pushed the tube up out of the grommet using a bit of wooden dowel .
I'm currently doing brakes (over a MONTH wait for a L/F ATE caliper !
) and the door checks ~ it turns out the DPM took one ball bearing out of each door check.....
There's more but that's the main things .
