What colour is the sludge and what colour is the coolant in the expansion bottle?


Sludge could be a number of different things and the colour is the clue :)

I would think there is a problem with the head gasket :cry: or a gasket failure somewhere allowing the oil and water to mix.

I had a leak on the pipes from the expansion tank through wear and tear. And had them replaced do you think it could be that. And if so would this sludge end up wrecking my car.

Thanks a lot for help

I think you will be getting some problems in the future if its not fixed. There should never be oily sludge in the coolant. The sludge is showing you there is a problem.

Have a look at the oil on the dip stick and on the under side of the oil filler cap, what do you see?

Its difficult to tell. I doubt it was the coolant pipe that cause the problem, but more like somewhere where the oil and coolant get close to each other. Like the head gasket or oil cooler. Its going to need a good look at to see where the problem lies.


You could always clear it all out, flush it out, refill it with the correct coolant and see if the sludge builds up again or if those pipes that got changed had caused it.

Try flushing the coolant system and refilling with the correct grade of coolant then add one or two bottles of kseal to the mix run the engine as normal and see how you get on. I have heard of kseal doing great things for head gaskets like yours. It will be interesting to see how you get on. Good Luck and please report back either way.
