Water Pouring Out of Exhaust

[trevorcharlesmorgan]

I've had my Austin 7 Ruby based special off the road for a year or so whilst I sent the block to be re-bored and I also had all the head stud holes helicoiled. I finally got around to sparking it up and got it to run for around forty seconds, I stopped the engine as I needed to fill the cooling system before running it for longer. I filled the radiator with fresh water and antifreeze. I then turned it over and water came not dribbling but gushing out of the the exhaust, the same fresh water and antifreeze I'd put in a few moments ago. I was surprised by the volume of water that came out. I haven't taken the head off yet but it seams as tough the water did not get into combustion chambers as the water did not cause the engine to lock up whilst turning over. Any ideas?

Did you take the manifold studs out ? If so will need sealing. Head studs also need sealing in my opinion. Good luck

I've got the manifold on bolts rather than studs so yes got them all out when a removed the manifold, I'll have to get myself down to Halfords then to see if I can get some thread sealer. Thanks for your response.

I use PTFE tape for these threads.

It sounds to me like more than manifold studs. I think a leak from there would dribble not gush. Are you sure that the cylinder head gasket is tight?

It so happens that I recently did this very job and at the same time I thought I would make a photographic record of 'how to'. If it is of any use or help to anyone for the time being you can download the PDF file from here:

All usual disclaimers - it's how I choose to do it, which may not be how it is supposed to be done 'by the book'.

I did torque it up correctly I believe and it was a fresh gasket, I've just bought some gasket sealant and am going to try and use that with another new head gasket.

That's really great presentation, very useful, thank you.

Useless? Ouch!

Sadly my auto spell changed useful to “useless”

I really appreciate these notes and will follow them to the letter

Sorry!
