Turns out the headgasket is fine.

He did a block test (I think it was that?!) with blue fluid in a syringe type thing on the coolant tank. And it didn't turn green, even after ages. It was idling so long the fan cut in, so it was pretty warm, and still no green-ness.

No idea what has caused the mayo stuff. He said no need to do a leakdown test as it's driving fine :)

What're more he didn't charge me :!

ask for a LEAKDOWN compression test. that way you can be confident that if compression is low, why it is low.

a normal compression test will only show if its low or not.

It'll be fine

Because mine seems to be at the early stages of the head gasket going, is it still ok to drive? Or should I just try and avoid it? As I said, it isn't consuming any water or oil :)

No, it isn't consuming any water.

I have no idea about the power, it's a 12v and slow, but doesn't really seem different to when I first got it.

It struggles to start sometimes and I have to give it a blip on the throttle. When it's warm and I start it up, it sometimes has a funny noise, like running water.

:(

Not necessarily mate, the car running as it should? power still feels all there? any more than usual exhaust smoke? it using any water? if that lot is all good then i wouldn't worry too much just keep checking it every now and then under the oil filler and water etc, you could always do a compression test to give you peace of mind and/or try one of them things that you dip in to the water to see if it's contaminated with exhaust gasses but at this stage i wouldn't bother unless of course you start noticing any of the above questions coming in to effect! :thumbs:

2000 W-reg 12v 72,600 miles.

I just checked my oil, which is fine. Consumption is next to nothing as well. Nothing under the filler cap.

I then thought I'd check inside the coolant header tank thing, and there is like greasy white stuff floating on top of the water and in the cap. The car had just done a long journey, and cooled down, so I don't think it'd be condensation.

Is this bad news?
