Coolant glitter

Hey Guys,

I'm in the process of pulling the motor out for a K04 build.
I drained the fluid through the drain plug in the rear of the block.
I noticed that there are glitter like particles in the coolant.

Should I be worried?
I'm changing the water pump in the process.
The weird thing is the particles are all perfectly round and have the same size.
Maybe some leak stopping additive?

My guess also, probably something like k-seal...

Horrible stuff! . . Sticks around for ages even after a few flushes

Leak sealant by the looks of it. Usually copper sort of gold colour flakes.

How long have you had the car?
Did the previous owner maybe have a problem with the heater matrix?

Definitely k seal.

Ok thanks, will give it a flush when it's out.
