So i have bought a ford ranger sump to fit my duratec engine that is going in my bmw. Sump is at the back, and i think the pick up pipe will sit in the middle [not so sure as its still in teh post from america!] But the question is, how to stop oil surge? Can anyone give me some pointers please? I was told years ago about the xe to put a plate over all the bowl , put a hole in it for the pick up pipe say 4" around, then put a 1" lip going down . but not sure what to do here really thanks!!

Your plan sounds spot on. On my Escort I just have the plate without the lip, but the lip can only make it better. I did weld a box on the side that adds more oil capacity, but this was mainly because I cut a chunk out of the sump to clear the crossmember.

What is best for around the edges of the plate ? Gap or welded in ? Thanks

Can you weld aluminium? Or know someone who can? Making up something like this is cheap and easy, these are from Burton racing. Weld it to the base of the sump where the pick up pipe goes.

For the Burton style it can be welded to the base of the sump, that's what the side holes are for, to provide a constant pool of oil.

I'm slightly confused.
From the picture and your words, are you trying to work out how to stop oil surge whilst having the pick-up from the shallow area of the sump? If so, change the pick-up so it's in the cooler reserve of oil in the deeper area.
If not, then ignore me and go with the above. 🙂

I'd hope that the pickup pipe you have coming will reach into the deep part of the sump. If it doesn't, it is different to every other engine in the world, which doesn't sound like a sensible design to me.
If you think it needs further baffling, the suggestion you first made is the best. For oil to move sideways under cornering, it also has to rise up. By putting a horizontal baffle all the way around the sump and pickup, just above the full oil mark and fully sealed to the sides, the oil is prevented from rising up out of the sump oil collection area. The hole in the centre should just be big enough for the pickup and with a turned down lip. Most OEM sumps I've seen are built this way.

The pickup pipe sits slightly towards the front of the bowl in the sump. I've never tried it but I think the easiest way to mount a baffle would be to make a plate up similar to your idea then split it in half and weld it to the pickup pipe. You'd have to weld some bosses onto the sump to fasten it to otherwise.

What's the gear above the pick up on the crank? Never seen that before on a zetec/duratec.

so i had a go at the sump today, made the plate in steel, and it bolts to 4 pedestals that are cast into the sump itself. the tube is open to the front corner as its quite enclosed there. the bowl part is the rear of the set up, it is RWD in the bmw too. what do you recon then?

Looks like it'll work, what size are the holes to feed the base of the pick up.
