The 3rd gen V6 has the 2GR-FKS engine. The engine is both direct and port injection, which theoretically reduces or eliminates the need for a catch can that many owners might install on a direct-only injection engine. This was one of the few reasons why I choose my 2017 HL over the Earth Dreams direct injection engine on the Pilot.

 

Catch cans do nothing.

Its a DI and MPFI engine with dual injectors. No worries about issues that other automakers have...

There isn't a single catch can manufacturer that has ANY SAE-paper or independent testing, like SWRI, that can prove that it works.

I see the shit the cans I've installed in a couple of my cars catch. Pure moisture infested sludge. I cant imagine that shit is good running through any engine intake. It doesn't hurt the engine having one installed, but like I said, the shit it catches is well worth it in my book.

 

Awesome thanks. But I do have CC's in two cars. My 09 CTS has VVT and there too no need for one. But I put one in anyway and you wouldn't believe the shit the can catches. Pure shitty moisture infested sludge. I cant see how letting that go through the intake is healthy for any engine.

 

Its simply condensing steam and catch nothing

Its is not a catch can...... it is a condensation can

And, what it catches doesn't cause IVD deposits

 

Glad you guys know what you’re talking about. I had to look it up:

Here’s How an Oil Catch Can Works, And Why You Might Want One

Have a direct injection motor? You might want to see this.

So how much do you think Road and Track got paid for that advertisement?

 

Ask R&T to see how much they got paid? R&T do any really testing?

2 issues with catch cans.... They freeze in the winter which cuts off PCV flow and could cause seals/gasket to blow out. And, in any climate, its reduces PCV flow. Both are exactly the opposite of what the end goal of a PCV system is. Reduced PCV flow increases fuel/water condensation buildup in the oil. Neither are things that I would want in my oil.

I will quote the pdf that I posted earlier:

"Positive crankcase ventilation(Blow-by) was not related to carbon deposit formation"
So, you install the latest UNTESTED fad and claim it is the solution to all problems.

"Increase of IVD due to larger aging of lubricant"
So, if you believe your owners manual and believe the 10k interval is acceptable, then you reap what you sow. For OLM, by certain automakers, I'd worry. The movement to synthetic moved the intervals considerably higher.

"More carbon deposits were accumulated when the average engine load was low"
hypermileage much? brag about range of tank or mpg?

In this situation, the biggest fad turned out to be the biggest joke.

 

The build up on the valves occurs when the engine is OFF. It does not occur when the engine is running. It condensate settling hardening during engine cool down. Has little to do with the PCV system.

Toptier fuel needs to be considered along with the 1-2 bottles of quality PEA based FI cleaners. How many don't use toptier fuels, even with their walmart or cheapest Ahmed's 'good gas' station even with the Lexus purchasing income level? How many maintain their vehicles appropriately for their driving style? dealer only? textbook manual negligence only?

I haven't seen the issue with Lexus's. Can you show some pictures of the issue on D4S engines?

There is a difference among DI-only IVD/port build up when compared to carbs, TBI, and MPFI. Most wouldn't be able to tell that difference.
