Backyard DIY low energy sump

I have been keeping myself busy with this.
The 202 sump in a VK commode isn’t much chop for a decent engine
Deep section and oil pickup are at the front in these cars.
Pretty crummy baffle, too
There’s a lovely gentle slope for all the oil to run up and over straight to the rear of the engine
Under acceleration. I don’t think it would take too much, either.
The other brilliant design flaw is how little clearance there is between #5 and #6 big ends
and the sump floor back there.
So if the oil piles into the rear, the crank is swimming, which costs power - so goes the logical theory.
I figured a simple shelf sticking out over the slope would slow the oil down a bit, at least,
so this happened
Sorry this is disjointed, I ballsed up the photo business

My you-beaut new baffles
I figured if one is good, two must be better

Knocked up a new baffle with a couple of one way trapdoor hinges

That took some time, even pulled the hinges apart and drilled them out a bit so they
were super loose and floppy. Planned to sit around here somewhere.
Tons of eyeballing and measuring needed, too

Getting silly, now. Why not put some baffles on the sides to stop oil sloshing
when making mega-high G turns?

I can take the piss out of me, but the main ideas of these sump mods is
to keep the oil around the pickup at all times, and to try to keep the oil off the crank
at all times

Had to add some brackets to mount the thing, with welded in bolts to make it removable
in case it ever needed mucking out or filled up with engine bits that shouldn’t be in there

15 goes at sizing up the hole around the pickup left me with this.
Used a bit of 1.5mm aluminium

Nice gap at the rear for oil to run back into the front, and another gap right at the front
to let the oil form the timing cover back in too. I reckon it would hose in from there

I cut in some slots, and knocked them out with a hammer, piece of wood and the vice
Not pretty enough to have on your bonnet, but good enough

Thank god for aluminium, that would have been a bastard to do with steel
I also have a pair of rare earth magnets to glue in the bottom to grab any nasties.
Got them from jaycar electronics shop. Real strong too
Do I continue that tray further back till I run out of clearance?
Somebody stop me, please

Funny thing is, I’ll never really know how much all that is going to help, or how effective it actually is
unless I install a camera in there as well
If the motor survives ok I will know that is isn’t BAD at least
It has to help out some, at least.
Hope I can feel the 0.7 horsepower boost it gives

Nice job!!
I done the same to a six oil pan but to suit a Kingswood. Took a lot of time and effort and finding a mate who could TIG super well for bugger all $ Ill try and put some pics up also when I work out how to!
Clay you have seen the finished job
Unfortunately Its currently out of the car and the original engine back in while the 'good engine' has a little more loving.
