Right, but it's got to break through the fire ring into the combustion chamber. That was the point I was making . . . .

'Perhaps the most common failure point is between one of the cylinders and a pushrod tube (again, usually number four cylinder). This gives you a whole variety of alarming symptoms. The engine will run very roughly, blow oil out of every single joint and seal, and if you remove the oil filler cap huge quantities of smoke will belch out. At higher revs the engine may also start to 'run away' due to oil being drawn into the affected cylinder. A fair few people have been persuaded to pay up for a reconditioned engine on the strength of these symptoms, when all that is needed is a new head gasket.'

Ahh, yes, re-read your post....if it was from an oil way to the push rod hole, yes it would just circulate....What I meant was (and as I quoted from the GlenCoyne website above) is it is from the cylinder to an oil way (commonly the push rod hole) then that is disaster!

That's just reminded me of the Glencoyne website, which I had a look at ages ago and had forgotten about. I see it also shows a manifold gasket which has failed in exactly the same place as this one, and they say it'll blow oil out all over the engine. I thought as much!

Hmmm, I missed this post before. It was running rough for a minute or two when cold first thing in the morning.
I'm guessing the 'fire ring' is the noticeable ring in the gasket around each cylinder hole?

Yep, the fire ring is the 'lip' around the cylinder hole of the gasket....
If you look at the photo in my post, you can see where the gasket has blown through the fire ring and into the last push rod hole....

Yeah, I've just been reading through the Glencoyne Tdi pages. They've persuaded me to go to the fridge and get a Guinness

I suffice with my glass of Apple Squash
Now, I am not suggesting that is what it is, but it could be worth investigation when you Compression Tester arrives.

Definitely. I think I remember you saying, a week ago, that it'll be interesting to see if any oil gets thrown out of the cylinders (first one to look at will be number 4) when it's turned over.I suffice with my glass of Apple Squash
