Has anyone out there baffled a sump pan on a 6cyl motor? I am finding that the oil pressure is dropping right down under hard cornering, presumably because it is moving away from the pick-up in the sump.

If any one has any experience in baffling a sump, I would appreciate any ideas.

I have the pressed tin sump on an EF/EL.

Incidently, has anyone managed to get the sump pan off without either removing the engine from the car or taking the x-member off?

Check the pump pickup isn't pipe isn't loose and swinging in the corners. You can get the sump off but not out and pump out by lifting the engine slightly and dropping the sump. However, the engine needs to come out or the K member removed to get the sump all the way out. Dam crank is in the way.

Thanks. The pickup is not loose. Looks like I have to pull the engine out.

cheers,

Something doesn't sound right. Is it dropping under left and right hand corners? Is on the track or on the road? How fast?

And if you going to weld in baffles anyway you can look at doing it in situ; ie cut bottom off sump and weld in a new bit with the baffles (a bigger winged sump even).

The car is a gravel stage rally car. It happens turning both left and right during stages, which makes sense as the oil pickup is in the centre of the sump. I don't get much of a chance to look at the oil pressure gauge during corners, but it will drop from around 350kPa to 100 at the exit, before immediately rising again.

Cornering forces are actually reasonably high, despite being on unsealed roads, and on sweeping corners can be sustained for some time. In terms of traction, on a swept road (one where the preceeding cars have cleaned off the loose gravel to leave a solid base) it can be close to driving on tarmac. Tyre squeal is not uncommon!

If I do baffle the sump, I will take it out of the car. Welding upside-down sucks, especially when there is a pretty good chance the oil coating left on the inside of the sump pan will ignite...... ;-)

Hmmm my risk management mind says you're more likely to kill yourself drifting through the corners than welding the sump. But I agree easier to do with it out. Why not go dry sump at the same time?

Dry sump is not an option, unfortunately - the rules don't let us.

You won't hurt yourself drifting through the corners, only when you don't drift through the corners!
