testing for exhaust leaks
I've thought for some time that I had a slight blow from my kit cars exhaust, I finally found a tiny little blow so I've taken it apart
and put some exhaust paste on the sliding tubes and put it back together.
I'm pretty sure I can still here a slight noise but cant find the source anywhere, its a very slight 'ticking' noise. It may just
be valve/cam/engine noise and i'm being a worrying girl.
whats the best way to check for leaks?? of the smallest kind!?

could you completely remove it, disassemble it, plug the ends and fill with water? should leak out of any pin holes i think. or if you know someone
with a smoke machine...

Put a flexible hose on the tailpipe, start the engine and close the garage door...... sounds dafter than it actually is - within reason. Not ideal,
but its what id do to try and smell / hear / feel where its coming from.

Normal way of testing exhausts for leaks is to get someone to cover the outlet so the system pressurises , leaks will sound like a hiss

Do you have a stethascope. If so, take the end off so you just have a piece of pipe connected to the stethascope. Now you can use the end of the pipe
to listen for leaks by running the pipe up close to all the joints. when you get close to the leak, you will hear it. Failing that, just use a piece
of small diameter pipe in one ear. It works the same way as the stethascope, you might need to block your other ear off with an ear plug.
If it can't be fixed with a hammer then its probably an electrical problem.

That would be my suggestion too.
