Hey all, I changed the oil on my wife's '05 impala and noticed a larger than normal amount of metal shavings on the drain plug. It wasn't just the black sludge this time, but actual silver shavings.
I spoke to a buddy that was a mechanic for 25 years (but not for the last 15) and his best guess was timing chain and tensioner. I am wondering if anyone has any ideas or has run in to this before?
The car has 195k on it and AFAIK the chain has never been changed. The car is running like a top and has no odd sounds that would lead me to think bearings or anything like that, but what do i know? (not much)
Hard to say what's going on. But for as cheap as it is, I would recommend getting your oil tested if you still have some of the old stuff. Might need to wait till the next change though. They can tell you what kind of metal it is, possible issues, and give an expert opinion on your oil..
The oil is gone, and I am hoping it makes it to the next change (5k, 200k) to see if it was a fluke.
We did just do the intake gasket, oil pan gasket, and a few other things, so still a chance of being ok. Car is still in great shape, just put new tires on it too, so I am debating spending any money on this motor, or just drop in a lower mile one for $1000 if it comes to it.
Couple things, 5k on synthetic oil is just fine. We just changed the intake gaskets, oil pan gaskets, and a bunch of other things within the last 5k and the engine looked very good. There was virtually no sludge or anything, it looked very clean. The engine has 195k on it, so I think we were doing something right.
sludge isnt normal. its burnt up oil, i put 3k on reg oil and when i drain it its still smooth no sludge. so you prob need to clean the engine out. and figure out why you have sludge, idk if its your oil or was a used car or what but it aint "normal"
