Thanks for the comments. Noise is same warm/cold, in/out of gear. Idle seems a bit rough. I looked for external rattling but see nothing. I think engine runs ok, could be light on hi-end power. Some soot on transom.

Flywheel fan is interesting. Think I'll lift the valve cover and take a look there too. Nick, thanks for the encouragement on the injectors. Yanmar made it sound like not a DIY job. Of course, they wanted... ]]> feeds@yuku.com (captrick) http://catalina42discussionforum.yuku.com/sreply/2932 Tue, 04 Apr 2006 15:59:49 GMT http://catalina42discussionforum.yuku.com/reply/2931/t/Yanmar-injectors.html#reply-2931 feeds@yuku.com (nickwigen) http://catalina42discussionforum.yuku.com/sreply/2931 Tue, 04 Apr 2006 14:06:44 GMT http://catalina42discussionforum.yuku.com/reply/2930/t/Yanmar-injectors.html#reply-2930 When you replaced the injectors did you need to add any new gaskets or packing?

I don't know if the injector could cause the rattle but they should be inspected and set, especially if they haven't had any attention in 1600 hrs. There is no special tool required. Disconnect the high pressure line and the rubber leak-by hose. Then loosen the nut that holds the fork-shaped injector retainer. The injector should come out fairly easily. I took ours to a local diesel service shop for cleaning, testing and adjusting.

A couple of questions in response.

Does the same noise persist when in-gear at idle?

Is the engine hot or cold when the noise is heard? Any change in sound from cold to hot?

Does the engine generally run OK, with adequate power, no smoke, etc?


Two possibilities that have nothing to do with the injectors... ]]> feeds@yuku.com (yorkrose) http://catalina42discussionforum.yuku.com/sreply/2928 Tue, 04 Apr 2006 11:12:53 GMT http://catalina42discussionforum.yuku.com/topic/1031/t/Yanmar-injectors.html ... ]]> feeds@yuku.com (captrick) http://catalina42discussionforum.yuku.com/topic/1031 Tue, 04 Apr 2006 07:49:54 GMT
