|The sump from the 'new' engine, Y18D, showing a nice coating of carbonised oil.|
|In this photograph the sump has had the rear anti-surge plate removed.|
|The 'old' sump from S18K. Plate 'A' was up-side-down with the embossed cross down - this would allow oil and debris to rest on its upper surface. 'B' shows the mounting brackets for the anti-surge flaps connected by flanges on the top of the walls - compare this to the face mounting of the 'new' sump on the below. The oil pick-up pipe on the old sump had the cranked end at the rear (compare with top pictures) which pushes the pipe out of alignment with the cut-out in the forward wall.|

A clean pan prior to re-assembly. Care must be exercised, when removing the hard carbon deposits, so that the painted inner surface is left in tact. I assume this to be some form of lead-based paint which was applied to seal any porosity.
|Finally reassembled with the pipe in its cut-out and the rear plate the right way up. The pick-up pipe is a metal to metal joint which was sealed with a thin coat of hard-setting joint compound. All nuts are secured by tab washers.|
