Hi Advice Please

Are chasing a dipstick for my EJ Motor - However in the meantime can anyone tell me the exact measurments of the EJ dipstick.

I need to make a measuring device with wire to ensure I have the right amount of oil in the sump and to keep me going.

Can anyone please tell me the measurements from the bottom (end) of the dip stick to the 'add' line, 'full' line and to the bottome of the dipstick handle where it meets the top of the tube once inserted.

The external dipstick tube length (not included portion hidden in crankcase) on my EJ is 12 cm

thanks Jeff
