My new engine is based on a 93 Range Rover 3.9 block.
I believe the range rover sumps are slightly different in size to a SD1 sump. I know there was a post on this subject but can't find it in the
archives.
Is it just slightly deeper in the main pan area and the same as a SD1 at the front, if so I presume I'll need the dipstick and tube from a R/R to get a correct reading for oil level.
Also the SD1 sump has a plate at the rear that bolts to the bellhousing whilst the R/R one doesn't, is that relevant?

Kevin,
Deep section of the sump extends further forward than the SD1 to give greater capacity.
I thought dipstick and tube are always kept as matched pairs for vehicle types because they have different lengths above the block, but oil level might be lower in RR to avoid oil getting in the way of the crank on rough terrain when the vehicle is at odd angles.
RR drain plug is on oppositre side from SD1 which might cause exhaust clearance probs in MGB.

As I recall the Range Rover sump is deeper, and indeed you need the right dipstick to go with it. Not sure about the dipstick tube though.
And yes the SD1 sump does connect to the bellhousing and the Range Rover one doesn't.
They are interchangeable as far as fixing to the block goes. The SD1 has a windage tray on the bottom of the block whereas the Range Rover doesn't.
I suspect the main motivation for the Range Rover one is to keep a good supply of oil at steeper engine angles.

A scan of the Rimmer Bros website will tell you what the variants of dipsticks are.

Hi kevin
the sump plate is to tie the gearbox to the sump,but i have fitted a th350 and have removed mine.
i have rebuilt my sd1 engine with a new 3.9 block,the bottom end has a baffle plate in.the sd1 was bolted to the bottom of the original block.the later engines had it welded to the sump.talk to rimmer bros about your engine spec and can advise you on the correct one.
cant find my book to get you the part numbers,sorry

Thanks for the replies guys,
The engine is being built with a 4.2 (77mm) crank and I was wondering about clearance issues at the front of the sump.
I could use either of the sumps SD1 or R/R but it would be simpler to use the R/R one because the SD1 is on the the other engine which is still in the car.
Clearly the R/R sump has a larger capacity, how much bigger is it?
The new engine is going into the MGB, and the only potential problem with using the R/R sump would be clearance with the front crossmember but from memory I don't think that will be an issue.
