Just reread my post and it sounds like I have driven a Gen2. I have not. Still have my 16. From my reading the Gen 2 is better torque and more refined. Maybe someone else who has driven both could chime in.

Its still a huge inconvenience to go through even if you have $7000 to throw into a dumpster or a warranty (considering Subaru honors the warranty)

Honestly I don't know what I am going to do. Its not pleasant to see all the cases online where engines blow up, videos of rtv in the pan and videos of oil pressures dropping dangerously low in right turns. After seeing those I start looking how much used M240s go for... This is not what I was expecting when I purchased my first ever new to me car. I was hoping they did their homework with the 2.0 engine and improved on it in the 2.4. But it seems they fixed some issues but others appeared.

But then I take it to autocross and its so much fun to toss this car around and I tell myself: maybe I ll get lucky, well its only autox not track, I don't have that much miles on the car, I ll keep it for another year and see what happens.

But what I am for sure not doing is taking it to the track. The evidence against it is just too much. Maybe with the next car I ll take the local HPDE school and dip my toes into tracking. For now I'll stick with autox

I hope you are right. From what I understand someone already tried to fix this issue with a oil pan baffle but it had almost no affect on the pressure drop issue.

A good review from the same thread —> https://www.ft86club.com/forums/show...&postcount=653

There are a few back to back comparisons in this thread.

There's a ton of different baffles and approaches to baffles out there. We've only got detailed data on a specific baffle. I'm sure theres a baffle design out there that will mitigate the issue.


Worst case, start saving up for a dry sump.

Or for a new car

Funny anecdote, walk out of work yesterday. A guy that was testing the fire alarms in our building is parked besides my car. We start talking, he used to have a 2013 frs. First thing he starts talking about is how he blew his engine twice..yikes.

Thanks, I wish I was able to trade to the grey series years ago. What a beaut.

I have the 100k 7yr warranty and never planned on tracking the car so I’m not worried nor do I plan on modifying the engine to void my warranty. Still waiting on oil pressure info for people that spirited drive on mountain and canyon roads.

Good test would be to do a lap on the �� dragon with all the switch backs.

I’m honestly pretty certain the g loads you get on the track would be insanely reckless to try on the street to be “low oil pressure” detrimental but waiting to be proved wrong.

The stresses exposed to a car on track are close to impossible to replicate on public roads. If a potential engine flaw that's exposed on track is also able to be replicated on public roads there are some serious issues going on.

FYI the IMS issue affects M96 and M97 engines. The years affected are 1996-2009, not merely 2000-2005. And while there's an easy solution for the (weaker) M96 IMS, for the M97 the only way to upgrade the IMS involves engine disassembly. So in reality, no solution for the M97. :sigh:

I think he is referring to how the IMS issue while definitely real was overblown. In many cases if the car had high miles and the IMS did not go yet, most believe it will never go. Not sure anyone has any real good data on it other than maybe Porsche.

So the engine issue while real maybe overblown as well. Time will tell.

Oil starvation from high lateral Gs is a design flaw. I am guessing most street driven cars will not experience this issue.

RTV coming off is a manufacturing defect. Subaru should be able to figure out how to fix this. Are the newer cars still having this? Or is the issue less severe now?

Been wondering about that myself... the cases I've seen showcased on YT, socials, etc were 2022 models.

A very interesting takeaway I got from this comprehensive video late into its runtime is that based on the test car data it appears the noted oil pressure drops from 50-60psi down to 20psi on certain turns happen at 6k rpm and above.

Further, that with at least one of the drivers who submitted analysis data they found that simply dropping into one higher gear on the turns where the pressure drops normally occurred to reduce the RPMs (by 800-1000rpm, say) pretty much eliminated the pressure drops on those turns.

Again, according to what they stated in the video above at 1hr, 14min in.

Someone please correct me if I have misunderstood what they were saying but this makes sense to me since the less your RPMs the less oil pressure you would need anyway at that given lesser RPM.

This isn't something billed by them as an actual solution to the problem but it would seem to be VERY valuable information for anyone who simply might want to play it safe(r) on turns that might concern them.
