pflaming Posted August 25, 2018 Report Share Posted August 25, 2018 My truck cabin noise continues to increase. The source is the engine because it is now obviously present when the truck is parked. So several source: water pump bearing, alternater bearing, loose valve adjustment, timing chain. I removed the fan belt, the noise remains so valves or timing chain. So whichever it is, some work involved. If it's the timing chain, then repair best be NOW? If that goes out, would that ruin an engine? Valves is mostly inefficient explosions and then possibly burned valves eventually? . Quote Link to comment Share on other sites More sharing options...

pflaming Posted August 26, 2018 Author Report Share Posted August 26, 2018 ". . . when the timing chain is loose, it may cause a vibration inside the motor and will be indicated by a rattling noise as the engine idles. Anytime you hear a rattle it means that something is loose and needs to be fixed before it breaks." I read this on the web. Hearing aides or not. I'm going to get to give that chain a close look. Probably best to pull the radiatorto remove the chin cover. Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted August 26, 2018 Report Share Posted August 26, 2018 Before you start tearing things apart, get a mechanics stethoscope and listen around to see where the noise is coming from. A broom handle or long dowel rod will work too, but the mechanics stethoscope is much easier to use. Touching different parts of the engine while running you will hear many noises. When you get to the one that sounds like what you are hearing, only louder, you have found the source of your noise. You can find a mechanics stethoscope for $8-$15 on Amazon, and you can probably find one locally too. I don’t know how well they’ll work with hearing aids. May need to remove those first. 1 Quote Link to comment Share on other sites More sharing options...

pflaming Posted August 27, 2018 Author Report Share Posted August 27, 2018 Hit serious about my engine noise. Took it to a mechanic friend, who confirmed the chain is loose, he advised it be changed. Darn, that is a bit of work. Remove hood and radiator, for openers. Quote Link to comment Share on other sites More sharing options...
Matt Wilson Posted September 1, 2018 Report Share Posted September 1, 2018 FYI - I spoke with George Asche last year, regarding engine rebuilding, and recommended using a drill bit to open up the hole in the little oil nozzle that oils the chain. He said the factory size is a little small and doesn't provide quite as much oil as it should for long chain and sprocket life. He didn't know exactly what size drill bit he uses, but just said, "it's the first one in the set." Of course, the size of the first one in the set all depends on which set one owns. At any rate, I'm sure opening it up any amount at all will help. Quote Link to comment Share on other sites More sharing options...
