Hi guys,
I've been lurking around here for years but just joined since a problem cropped up on our 560 diesel and I could really use some help. Just started it up the other day for the first time in a couple months noticed a strange noise at idle. It's much less noticeable when given some throttle but is very noticeable at idle and seems loudest when on the left side of the tractor around the top end. When you shut the engine off, before it comes to a complete stop you can hear the noise more clearly and it sounds like a sharp rushing of air, not metallic in nature. Kind of like a loud TSSCHHH, that gets softer as the engine comes to a stop. Tractor seems to start fine, slight greyish smoke that clears up as soon as it warms up, runs and idles as smoothly as always except for the addition of the noise it never had. Oil was changed a few months ago is is still clear/amber with no water or metal that I can see, coolant looks perfect. Oil pressure stays good and temperature doesn't go above warm. I'm used to working on gas cars/trucks and our old 300, but not sure where to start with this one. I can get a hold of a diesel compression tester, but I'm not familiar with the procedure. What should be removed and where does it screw into? Will I need to find a special adapter that fits these old International diesels? I also have a leak down tester, is there anything different involved in using it on these engines? I haven't tried cracking the fuel lines at the injectors yet. Valves haven't been adjusted for the past few years since she always runs so beautifully. Any other test/checks you guys would recommend? Any and all help will be GREATLY appreciated. We are currently re-roofing our 100yr+ old farmhouse and funds are definitely limited. I really hate that dang Murphy and his stupid law.
Thanks in advance,
Dan
