Shortened sump
I bought a cut down sump a while back for the XE,with my recent probs I am getting panicky again.So do you think this shortened sump is O.K. i.e will
it hold enough oil,do you think oil surge might be a problem.I am not sure in the difference in capacity but it is about 1 3/4" shorter than
standard which is just about right for my ride height.I am not planning on racing or track days and the standard one is def to low.

errrm, is your engine installed vertically? (I ask as its difficult to get it on the 7 degree slant in a 7)
If its vertical you don't want a 7 degree sump like the std one you have in the pic, even if it is shortened.
If your engine is installed level, then you need to make a level sump, easiest to start off with a steel sump off an 8 valve vauxhall and weld it up
from that.
My caterham HPC wet sump is very shallow, but foam baffled and parallel to the engine bottom face along its whole length. Its slightly deeper at the
rear than the front, and basically as deep as the flywheel.
The sump is deeply ribbed though so the actual internal depth is 1/2" or so shallower than the very bottom of the flywheel.
The sump ribs, flywheel and bottom "open" face of the bellhousing are all within 5mm of each other in other words.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

"foam baffled"? how does that work then?.
Do you run an oil cooler to help increase the oil capacity?
Do you know anyone who wants to buy a 7deg cut down sump? and someone who can make me a parallel one.SBD want £230

hi, sorry for the slow reply.
The foam is fuel tank foam, and is used quite commonly on competition cars in championships that don't allow dry sumps.
On the Caterham sump its held in place by the std vauxhall windage tray that fits between the block and the sump.
I don't have anything to increase oil capacity, and don't run a cooler at all. It was one of my big worries. You have to overfill the
engine with oil (as per caterham who re-marked the std dipstick on wet sump HPC's)
I run around 3.8 litres of oil which is about the same as the volume used by the opel manta 1800 which uses the popular alloy "big wing"
sump often used on the XE engine.
I have a steel sump that you are welcome to if you want to weld up one of your own, though I don't have time to make one for you I'm
afraid!

Yukspeed do a modified steel sump with big wings,with baffle.Its 110mm deep for £160.A guy on the Westy site is also sending me some photos of a
damaged SBD one that I might be able to repair.
Thanks for the offer of the sump though,but I would prob distort it all out of shape welding it up.
