Well. folks it's still leaking! I did a gas test which proved negative i.e. the liquid stayed blue.
I have put it on a two post lift again and checked thoroughly but no sign of any leak. I left the engine running for about twenty minutes as well, still no visible leak. I note Trickey on here knows a member with the same situation but who had a respected garage change the head gaskets but the car continued to leak. There is some mayonnaise visible when you remove the oil cap but I put this down to the fact that the car is not being used very much. There is no coolant on the dipstick. I don't know what to do next apart from removing the heads and changing the head gaskets. The car is no good with the leak so I think this is the last ditch attempt at solving the problem. Any other suggestions please? Martin |

Perhaps a long shot but I'll mention it anyway. My daughter's 75 came with a leaking hose (bleed screw one) that the previous owner had "fixed" with some pipe and two jubilee clips. It still weeped, so I replaced it. Couple of days later daughter phoned, please tow me home - car overheating. Traced it to another leak, but this time the other large hose from the thermostat - took a while to find as it has a kind of sheath and it leaked from inside this sheath.

There is nothing for it other than to take the heads off and replace the head gaskets. I will have to choose my moment as I have to work outside. It will take me about two weeks but I will not be working on it full-time.
I will report back! Martin |

Have you had a pressure test carried out on the cooling system?

When i have had leaks thats the first thing i do - up on ramp engine on and undertray off - done it twice in 6 years - first time she was running for an hour when the leak was spotted from the IMG - leaked only when really hot - 2nd time a few minutes - the small turbo hose had become loose as the clip had failed.

I have reviewed the evidence you've provided which is relevant to a head gasket failure. Please read through your own words again: Quote:

In respect of the "some mayonnaise" you've reported present in the left-hand bank which you put down to infrequent use, if I were in your shoes I would seek to test that theory. A dose of Comma 'Flush Out' flushing oil may remove the emulsified oil but I could not give you a guarantee. Why don't you take the car for a long journey (several hours) and check that the coolant is reaching normal operating temperature by using the built-in instrument pack diagnostics. You should see temperatures in the low to mid nineties, rising to 100 degrees when subsequently stationary in traffic. One thing which doesn't appear to have been mentioned is the coolant level in the expansion tank. Are you observing the tab labelled 'max' within the tank? If not, it will be overfilled and will eject the excess. Martin, your plan to remove both cylinder heads in the open air is born of despair and not from the evidence available and reasoned analysis. It is an enormous job involving a timing belt change which should not be undertaken lightly and I just don't see the evidence to justify it. Simon

I have read through this thread today and half way through i was thinking maybe to much coolant is being put in, thus not giving any expansion so being ejected out the cap. 1 2 Please ignore if the coolant is as above in the photo's

No Steve the system has not been overfilled. Simon I take your point about evidence but I have run out of ideas as to where it is leaking. The car is only being used for short journeys as I am not too keen to take it on a long run which might then cause it to overheat. I suppose I could check the water temperature as you suggest but I doubt that is the problem but we will wait and see. Anyhow I have no intention of taking the heads off at the moment I shall wait for warmer weather. I have done the job before including stripping the heads but this time I do not intend to do that because the car has not overheated that makes the job alot easier. Watch this space!
