how to: sump baffling

When he’s worked out how far up the sump the oil
comes, Dave measures the length...
...Then the width — this time with dividers as you
can’t get a ruler in there!
Then transfer the two measurements into a trial
piece of metal, bent at the ends...

...He has made two so we can check for both
width and length before...
...Dave transfers the basic measurements into a
card template. Note: the baffle should end up no
more than 12 mm above the fill level.
Next we needed to establish the siting of the oil
pick-up. This can be tricky because it’s a very tight
fit in the block — ours is a dummy and difficult to
get out again.

Then you need to check the fit of the oil pan —
normally you’d need a maximum of 6 mm
between the gauze and the bottom of the sump
but ours is spring loaded...
...So it touches the bottom (which is normal),
where you’ll find a witness mark.
With this established, we measure the
dimensions of the pipe...
14 15 16
...Plus those of the head of the pick-up pipe gauze,
which will establish the size of the hole needed in
the baffle plate.
Dave transfers the lot to the card template —
although this is the actual baffle being checked on
the dummy block!
After we’ve made our templates and established
the correct measurements, Dave transfers the lot
into Auto Cad, makes a drawing and has it
converted into steel at the laser cutters.
