B204 Sump Build

Hi All.

Any and all sump advice welcome. Just built this one to replace the SAAB B204 sump pan. Pics and description follows:

As the engine now runs longitudinally in the car the oil flow will be different. Forward and reverse will become left and right forces on the oil. Therefore the baffle plate requires modification along with the sump pan. The sump pan oil pick up well has been squared up so that all forces & flow are now equally. Using the existing baffle plate as the primary cornering oil stabiliser the next job was to change the new forward & reverse characteristics. This, if left unchanged, would have actually been far to restrictive for the forces involved. To compensate for this an oil flap has been introduced onto the baffle plate. This flap will act as an oil restriction when accelerating hard (especially up hill). As oil tries to flow toward the back of the sump the flap will be forced to close keeping oil around the oil pick up. In normal conditions the flap will be open allowing maximum oil pour down into the oil pick up well. The forward area of the sump is short and high up so hard braking (even down hill) should not create a problem past the existing baffle plate.

OK there be the theory.

Here be some pics (the black one is the new version).

All this to gain 40mm ground clearance! Locost but Hipain

OK what is the be'din obvious that I've missed?

A couple of us on uk saabs are developing a single stage pump dry sump kit for the 204 and will be doing a shopping list and exchange sump service once we have the price for the pump sorted

Have a look in projects for a thread by dan about engine conversions you will see the dry sump set up in a tiger six

Cool looks good

Question: don't the angle, on what will now be the back of the pick up well and slope on the rear of the pan cause unequal flow during cornering. Long left handers could cause oil creepage up the block wall or are you planning using a windage tray to prevent this.
