Help with a leak!! - Leak problems

[jim shearing]

Hi guys.Well I need some advice.I bought a 1/96 D&E Minatures Skipjack second hand.It is built,it is working,and it is great!...I am in the testing phase,and she has been down to a depth of 3 metres in the local outdoor pool.She works great,but there is a slight leak in the W.T.C....and even though I only get a bit of water coming in,I would like it to cease completely!...so what do you guys recommend as the best way to make the O-ring seals completely water tight...vaseline?..silicone grease?...whats the best?

Also,can anyone who has had a leak in their WTC please advise me if there are any other places to check for leakage,as I am having difficulty tracking down the actual leak (I am assuming that it is the O-ring seals that are leaking..but as they say, "assumption is the mother of all F*#@K ups !" )

Use silicone grease on all

Use silicone grease on all the selas on your sub. Vaseline hardens with cooler temperatures- not good!

Finding a leak is not a problem.
You want to fit a schraeder valve (tyre valve) into the WTC bulkhead, and pump it up a couple of PSI with a bicycle pump.

Submerge in water, and the leak should make itself apparent by the exit of air bubbles.

Generally a good idea to do this each time you go sailing, too!

I'm a big fan also

I'm a big fan also of silicone lubricants for your seals. Be sure to keep in mind too, that positive pressure (IE;a few PSI)
within the WTC can result in bubbles emanatining from various joints. However, once the pressure inside is neutralized, there may be a halt to leakage. Don't confuse leaks with being "water-tight". If you have for sure seen water actually coming in though, then you have a refit project in store for you.
