Chalk
« on: 07 August, 2021, 21:19:24 »
Evening all,

I remember chalk can be used to help identify the source of an oil leak. Could someone advise me, please, what kind of chalk to use, and how to use it?  Thanks in advance.

Phil.

I use oil dyes. You can isolate where and which oil depending on colour.

Where can you get dye of different colours? I've only known red dye.

The thing about chalk is that it leaves a track, so you can see more precisely where the oil escaped from. Any advice on chalk?

You need one stick of white chalk and a blackboard....

Then, in large capitals you just write   " B S A "  on it.  ;D ;D ;D

Cheers,

Excellent, very good, Bernie. But hope springs eternal - it must be possible to achieve oil - tightness.  Phil

Clean the area in question then shake some talcum powder over it. The oil will show a track from it's source.

Powdered chalk can be found where builder's supplies are sold; ask for chalk line chalk.
