Why does my 22re sound like it has some rattle clatter happening in the front end?
If the guides are fully intact, is it possible for the chain to be loose enough(either from wear or a malfunctioning tensioner) to have the chain clatter/rattle? Timing set has been allegedly replaced within the last 60k miles. Don't know the brand.
First start up there isn't any timing chain rattle. But shortly after pulling out of my driveway and hitting 3rd then coasting to the light, there's a light clatter/rattle on decel and while sitting at the light. Bring the rpm up a bit and it gets louder, then will go away...or maybe just gets quieter or drowned out from the exhaust.
Once the truck is warm/hot there is no clatter sound at all at idle, revving, or coasting. If I shut it down and restart it shortly after(say within a minute) the truck has no start up clatter and doesn't make any noises and runs as it was before. If the truck sits say 10 minutes, it has a bit of start up rattle then goes away after a 2 seconds. If the truck sits for say 20-30 minutes, this rattle goes on for an extended period of time (say 10 seconds) before stopping or it'll have start up rattle that doesn't really go away similar to what happens after pulling out of my driveway, then will go away when the motor is driven a minute.
when the truck is making the noise it is loudest just sitting at an idle at an exact rpm (say 1200rpm) and doesn't have a ramped up clatter noise on decel if you just snapped the throttle open and closed.
Truck runs mostly pretty mint. On hot start sometimes it misses the first crank and I have to hit it twice. Always been like that as far as I recall.
The extended rattle/decel clatter is recent in the last 3000miles (more so in the last few hundred miles, but I first noticed an a hmmm...that noise is new roughly 3k miles ago and only did it after hot and sitting and only sometimes, now it is pretty predictable and will do it cold and after pulling out of the driveway and will always go away once warm/hot) Before that it for sure only ever had the initial 2 second fire up clatter after hot and sitting. Not sure if these are even the same sound but it's worth mentioning. When I first noticed the noise I adjusted the valves and inspected the guides as far as I could see w/ the valve cover off. But now it's getting persistent enough something should be done if I expect this to be my daily driver without unexpected downtime.
How can I better diag this before replacing a timing set that may not be the problem? Can a water pump make these kinds of noises?
