old man emu Posted October 2, 2014 Share Posted October 2, 2014 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: http://www.motorcycle-superstore.com/25416/i/moose-racing-exhaust-plug Old Man Emu (Disclaimer: I don't have any financial interest in the shop.) 1 Link to comment Share on other sites More sharing options...
pmccarthy Posted October 2, 2014 Share Posted October 2, 2014 I think I could update my software with one of those. 1 Link to comment Share on other sites More sharing options...
Guest Andys@coffs Posted October 2, 2014 Share Posted October 2, 2014 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.

facthunter Posted October 3, 2014 Share Posted October 3, 2014 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 Link to comment Share on other sites More sharing options...
Downunder Posted October 4, 2014 Share Posted October 4, 2014 Don't turn 912's backwards either....oil issues. Link to comment Share on other sites More sharing options...
Admin Posted October 4, 2014 Share Posted October 4, 2014 And always turn 912's forward a few times by hand till you hear the burp before start Link to comment Share on other sites More sharing options...
facthunter Posted October 4, 2014 Share Posted October 4, 2014 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 Link to comment Share on other sites More sharing options...
