Dave´s Auto Center V35A-FTS Tear Down

I ordered the oil filter cutter

Can you provide a link to this cutter?

The folks reading this post likely aren’t the ones that need to hear it but this is why we change our oil much sooner than the 10K recommended interval. Turbos/debris is a death sentence for an engine.

I still have my first oil filter from the break in oil change at ~300 miles. I’ve been meaning to cut it open but haven’t found the time. I expect there will be a decent amount of debris (which is expected for any new engine, to a point). Looking forward to seeing @Garauld analysis.

I am all with you in terms of more frequent oil changes. But I think the challenge with this is that the debris will hit the bearings before hitting the filtration system, and one "visit" to those bearings is one visit too many.

Here's the cutter I bought for $17:

You’re absolutely right, my comment was worded poorly. I don’t think there’s much we can do about the possible debris as owners. It’ll likely come down to luck— some folks engines will fail, some might be ticking time bombs, others might be spared.

We can try to limit effects that may cause or speed up the snowball effect, one of which is frequent oil changes. As you know these hot turbo engines cook the oil reducing its effectiveness. The guy in the video talks about it some.

When you say luck do you really mean the date of manufacture of the engine, as in "I was lucky the engine was made after the debris issue was fixed"?

Toyota has already identified the root cause and narrowed it down to specific dates. Ref this thread.

Granted there is a lot of guessing and speculating out there that the recall might expand. Anyone who says this needs to answer wahda you got, point to something tangible. Or else it's the opinion of one person.

By luck, I meant, if your engine is affected will it be damaged. Not every engine on the recall will grenade itself before its replacement date. Theres plenty of engines on the recall that are chugging along just fine. This is to say there’s countless variables which cannot be accounted for when it comes to Foreign Object Debris/Damage (FOD). Unfortunately, some will draw the short straw.

I got my oil filter cutter late yesterday (I am very pleased with it and highly recommend it if you plan to buy one) and opened up the two filters I have changed so far since I bought it. The first one, changed at 764 mi showed a fair amount of light shimmer similar to the pearl found in a fine to medium metallic paint. No larger specks were noticed. The second one, changed at 5690 did not show any fine shimmer that I could detect. I'm happy with that!

Waiting to 10K for 1st oil/filter change because it’s free is ridiculous. I think changing oil & filter multiple times in the first 10k miles is a significant preventative measure if you’re worried about swarf. Being blunt, it’s the only thing you as an owner could possibly do to delay or mitigate the issue. All first oil changes are going to catch debris from engine components breaking in & manuf. debris. The good news is the filter system is normally immediately after the oil pump in most engines - meaning oil is filtered before being pressurized & circulated. I haven’t found a diagram of the V35A oil circuit sequence to completely confirm the filter sequence location. Oil is doing 2 main things - lubricating parts & helping pull heat away from critical areas. Maybe we should add a 3rd use is that it can help clean out impurities in the oil circuit. In the engines I’ve been around the conventional oil circuit is something like -
Oil pick up
Oil pump
Oil filter

• Oil cooler
• Oil pressure valve

Main/rods
Pistons
Mid galleries, timing chain, tensioners, turbo(s)
Upper galleries cooling valves
Camshaft(s)
Cam squiters
Lifters

When you shut down an engine much of the oil eventually drains to the sump/pan, but there is still oil left in your engine. It’s in galleys, tensioners, lifters, etc. Drain your V35A & let it sit for 2 hours & it will be hard pressed to get 7.7 qts back in without overfilling. I barely get 7 qts back in. Use the proper spec oil (not just the weight) so that the designed oil film remains almost everywhere - especially on flat bearings, & critically for turbos. Pull off the highway to refuel, & when you shut down the engine your turbo impellers are still spinning @ crazy rpms on its bearings. Car makers use to give strong warnings w/ turbo engine owners requiring a 2 min idle to prevent turbo bearing damage, but today’s turbo design & synthetic oil make prevent problems. That same oil film allows us to cold start without catastrophic effects giving protection as oil pressure builds within a second or 2.

Just recommending the common sense. - change your oil & filter often & with appropriate oil for your driving conditions.
Good oil, good filter & let the filter do its job.
