Workhorse W22, Chevy 8.1l exhaust rattle/noise
Good afternoon,
I went today and started my MH since it’s been in storage for several months and ran it. It’s a 2003 Windsong, Workhorse W22 chassis with the 8.1l vortec. Upon warming it up and driving it, after it was warmed up, I noticed a loud rattling noise at idle. I know the 8.1l have lifter noise, but this was coming out of the exhaust area...I couldn’t really hear it by the front of the engine or by the doghouse inside...but it was very loud out by the exhaust outlet. The only way to describe it is as a very loud rattle/vibration but at the cadence of the motor running. It did get slightly louder with increased RPM, sometime it would go away, then come back when you increase RPM.
It sounded like something is rattling in the muffler? Again, it’s very noticeable, I could notice it sitting inside as well.
Thoughts? I checked the engine oil, they’re where they should be. Could this be something internal to the engine and noise is coming out the exhaust?
Thanks,
Doug
