Locating a very slow leak

Hi

can anyone offer some advice re the locating of a really slow leak.
I have an sr4 that had leaky tubes when bought. I felt this was due to having the valves replaced with champagne corks. I have therefore changed all three valves with nice shiny new ones and I thought all was good. The tubes now hold air well appart from port side that looses presure over about eight days. I have gone over it with soapy water and can see nothing. I feel it is so slow as to not be distinguishable but affects it over time.

Any suggestons on locating and or rectifying would be greatly received

Glenn

they're buggers them small leaks, if the air's getting out it will blow bubbles, you have to go over ever square inch, it might be a scratch or a cone end or up under the tube on the inside, we've had boats in here and sometimes it takes hours to find something that you can fix it 5 mins

Tube leaks

Try dowsing with a pair of welding rods. Sounds odd, but has worked for me.
Work along length of tube then around the suspect section.

Thanks guys

Went out today and with some very soapy water found a very small pin prick under the tube. it was only venting if you actually put pressure on the tube ?? but cant find anything else so guess it must be the one.

will patch tommorowwww and see how it holds.

Hint.

It's usually easier to find water by falling in
