I’m getting a strange metallic sliding sound after a recent oil change that sounds sort of like a tea kettle.

I have a manual transmission happens if I stomp on it at lower revs and happens when I rev up also, hoping I don’t have a rattling timing chain again at 135,000 miles
 
Maybe you have some pre ignition issues ? bad gas / too low octane ?
Also they are known for timing gear related issue's

I might have to dump in some fuel system cleaner very strange noise, I had the chain need replacing before and this sounds very different and it’s only at higher revs or pushing on it. Kinda sounds like loud drivetrain noise but it’s not rattly.

Started right after the oil change, drove a whopping 2 miles everything fine, went home then on a 70 mile drive the next day and it started mid trip.

All fluid levels normal, oil looks clean.

Been running pp10w30 a long time and the motor was always quite until the oil needed changing
 
How many miles on the latest timing chain?
Remember that most aftermarket parts are junk now and will last half as long as the factory original. I installed a new Cloyes timing chain kit on my 96 Saturn DOHC and it started rattling at 50k miles. I thought no way that's chain noise but sure enough that chain was stretched right out and the tensioner was at it's limit.
Only used synthetic oil changed every 5000 miles.

GM dealer was forced to do the chain at 65,000 miles under a courtesy repair and paid 50/50 so everything is OEM.

Looks like my car destroys chains every 65000 ish miles. Its not driven particularly fast or aggressively and the oil gets changed a lot with synthetic

Noticed from a cold start it revs and stalls if I don’t give it gas so the chain/guides must be going again despite the noise being very different than last time.

The last time the chain issue came on slow, this one was pretty abrupt

I’m far from home so now the decision to baby it and attempt to go back and potentially get stuck here in Tim buck nowhere .

Or worse choose to get stuck in Tim buck nowhere on purpose with no available entities to haul or work on it.

So the replacement chain is at similar mileage?
And that’s a redesign of the chain?

It shouldn’t have the defective guides that the original had but I’m guessing it’s not any more durable.

Won’t really matter if I can’t make it home, will spin the engine replacement lottery.

Strange.

I had no chain issues at 150k until someone ran a light.

Wonder how well the dealership did the job…..
 
Survived the 150 mile trip home, kept revs under 2000 as much as possible and a light throttle downshifting to keep the racket down,

Will find out if my motor oil is sparkling and get it in to check the chain.

Sad part, because GM changed the chain there may be a lifelong warranty but the labor likely costs more than the MSRP of OEM parts and a 3rd party installation
