R-R PIII - dirty sump The sump from the 'new' engine, Y18D, showing a nice coating of carbonised oil. 
R-R PIII - dirty sump: plate out In this photograph the sump has had the rear anti-surge plate removed.
R-R PIII - old sump 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.

R-R PIII - sump pan

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.

 

R-R PIII - clean sump 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.
