Please don't confuse me with the BobinPA on the CR-V forum. Although I am a Bob in PA and I do know what MGAs are.
I hope things work out for you guys with your CR-V. Are you having any heat issues?

Being from Western PA myself I should not be making assumptions. My mistake.

I found this photo and post by screen name vpp1999 and thought I would share his comments about the 1.5L turbo valve cover.



Note the built in "catch can" baffles that condense vapors from the crankcase prior to going to the intake manifold (blue arrows). Those baffles help keep build up of materials off the valves (issue on GDI engines), but also condenses out gasoline vapor from the crankcase right back into the motor oil. The valve cover being plastic means it doesn't get hot through conduction and is probably super efficient on condensing out those crankcase vapors (including gasoline vapors). The cooler that these baffles are the more efficient they will be on condensing gasoline vapors back into the motor oil, so probably why the OD issue is worse in cold weather.

An external gas/oil separator is the only sure way to remove residual gasoline from your motor oil. Residual gasoline in the motor oil just doesn't get burned off when these baffles keep condensing the crankcase vapors back into the oil.

I like it. Explains the whole problem. He may not be right about it, but it sounds good and these days that's all we need to break out the pitch forks and torches. LET'S KILL HONDA!!!!

Bill, how's that compare to the underside of valve cover on your 3000? About the same, right?

The old expression "follow the math" appears to be the key reason Honda has handle this issue the way they have. A subscription only financial analyst report on Honda just reviewed indicates Honda had the lowest profitability of any of the major carmakers on a per vehicle basis. They estimate the profit was just 2% per Honda vehicle. Subaru was the highest at 9% even better than Toyota at 7%. The big issue with Honda is they don't get enough production out of their plants compared to the others. This may also be a reason for them taking a very short-term view on the OD issue and pretending it doesn't exist. They can't afford to hurt their profits. Motorcycles were very profitable for Honda.

^^^ Interesting. Honda doesn't do fleet sales. I wonder how that impacts their per-unit profitability.
Now let me head to the storage shed for my pitch fork.

We were talking tonight and we may be looking at Toyota or GM to replace our 2013 CR-V. I may wait and see if Honda recognizes the problem and either fixes or changes the engine.
