Possible Cracked Head?
I used to own a book "Everybody's Home Doctor", the trouble was, if you read it, you'd got it and in a way, reading through the information on this site, and elsewhere, I think maybe, I've got a crack in the engine.
Last Sunday at the Ugly Duckling meet, I arrived there with a large amount of steam coming from the engine compartment. It appeared that there was coolant coming from around the exhaust manifold of the 1.8T, higher than the area where the head gasket fits. I was able to get home, topping up when cool enough at the two stops I made in the relatively short journey home. I found that some of the exhaust manifold bolts were not torqued up, and one stud was completely missing. I now have a gasket, and am expecting some studs to arrive soon, so I was preparing the beast today for what to me is a major surgery. Whilst underneath I was aware of an occasional drip of coolant from around the area of said gasket, and in fact could see a slight run of fluid from the area of a lower stud, one which actually, if really turned, does not appear to tighten 100%. Now, on reading various historical notes on here, I realize there are no coolant channels to be sealed by the exhaust manifold gasket. In fact, some members report that in the past they too have had similar symptoms, but luckily, I don't think any had cracked blocks. I will now try to go ahead with the gasket replacement and then refitting of the manifold with new studs and will have to see what happens. I love this car, well most of it. I needed my car early next week, and my project car is not ready for the MOT. |

It won't be a cracked head, I've yet to see an 1800 suffering this malady Also common is the failure of the head gasket elastomer seal on the jacket spaces at the front of cylinder 3, causing the water to be ejected directly underneath the exhaust manifold. Best of luck Brian |

You may have to helicoil (The threaded insert type is better) The damaged thread, I have seen a couple where the threads have been pulled out by previous over zealous tightening!

Hmm, thanks for that, I've just watched a couple of advisory videos on Youtube for this action.

They work far better than a helicoil, I have used them on a few occasions, when put into aluminium, they are much stronger than the original thread.
