Our SUV ( 2019 Highlander with the V6 2GR-FKS at 50 000 miles) had the engine taken out by local Toyota dealership to fix a leaking timing cover, ( 2end time this was repaired ) and a second oil leak on one of the engine head gaskets.
The dealership sent me this pictureof the engine when it was dis-assembled last January at my request.
The repair was done under warranty, and engine has remained leak free and operating without any concerns.
Till this afternoon, we are now 4000 miles after the repair and I change the oil. When I remove the golden plug I find this :
On every oil change I get a sligh metal slugged but nothing like this. I don't have good feeling.
Take out the oil filter, it's just an element in canister, and it also is covered in very fine metal particles.
I extracted the expected 5.4 liters of oil , and went panning for metal but I did not see much.
Not sure what I make of this, but with no prior experience and motor still under warranty I was going to bring the filter and pictures to the Toyota dealership who did the work but with nothing wrong on the engine at least discernable I would like to know what I should be asking, dropping the pan and having a future look at the engine.
In Canada Toyota mandates oil changes only at 16000 km or once a year (10 000 miles) so I was proactive at 4000 miles. If the dealer just brushes off the concern I will just change the oil again before winter sets in to see if the metal specs are still present.
I don't see how opening up an engine to reseal gaskets and change engine cycling head gaskets' , both were change although only one leaking would cause metal specs or is this expected ?
