Exhaust Pipe Plugs

[old man emu]

I was in a motorcycle shop today and saw these:

 

 

They are plugs that are put into the ends of exhaust pipes to seal the cylinders to prevent moisture entering while the engine is standing unused for some time.

 

Here is a link for those of you who would like to buy some for your plane:

I think I could update my software with one of those.

I went into Clark rubber for mine and brought rubber feet for tube......They have about 1/2doz different sizes and for my Jab exhaust were perfect size. Just glued a red streamer to the end of each one........

 

I do like the orange colour of these ones though...start the engine if you leave the black rubber ones on and they might be difficult to find once the back pressure blows them off and tests your exhaust spring tension.

Tennis balls with an appropriate size hole cut in them

Also very useful if you get diarrhoea on a long flight.

CRC or equivalent, up the exhaust pipe when half cooled helps. Turning the engine backwards puts it into the ports. If the engine has a vac pump don't turn it backwards, otherwise it is OK. Nev

Don't turn 912's backwards either....oil issues.

And always turn 912's forward a few times by hand till you hear the burp before start

I'm a bit curious as to why you CAN'T turn a 912 backwards other than the usual fact of emptying some oil out of the galleries if you prolong it. Engines equipped with certain VAC pumps don't recommend it. If you want to be very particular you would turn a motor forwards till some oil pressure registered before you fired it up too.

 

When you install a new engine, before the first start you should pressurise the oil galleries and filter and oil cooler. Nev
