I've heard the most common thing to make them fail is lugging the engine. That is boosting under too high a gear; while cruising and then flooring it while at speed at say, 4th or 5th gear instead of downshifting to 2nd or 3rd then applying throttle.
Yup, I've got a couple pistons sitting as paperweights & ashtrays that look exactly like that. I was startled at how short a time that block lasted, and I made sure to do EVERYTHING right - fuel, maintenance, oil, tuning, etc. 18psi on a VF, 290whp, no knock.
pull the engine apart and give it a bit of a birthday - new favorite line right there. Thank you guys for posting the videos. Subscribed some time ago and these are invaluable.
I really appreciate these Aussie friends, awesome video sir! Whether you have a WRX or an STI it's never a good idea to go full-throttle under 3000 RPM. Bad doo doo happens then
Yet another really informative piece. Thanks for the clarification on the rods being a bigger problem on the FA20 and rings on the EJ25. been looking for that bit of info. You're good at painting a clear picture on how things work or go wrong and it is much appreciated.
I love MRT, but watching this video makes me nervous for my STi with 92k on the clock. I've been saving money for the inevitable but I've been driving these cars for 19 yrs and have only blown one of my 7 wrx/sti ringlands. I had no idea how to really drive a turbo Subaru when I was 22 (coming from the NA RS model) and probably lugged the crap out of the engine too many times looking back on it. You guys need to be here in the States!
Liked and subscribed.I just brought a 2017 STI it's got lots of mods including forged pistons bigger bigger studs and lots more.Its flex fuel as well I love these beast of cars
Hi Brett can you please consider doing a video on air oil separators and information on them/ installation instructions. I think it would benefit everyone considering how beneficial AOS’s are for Subaru’s.
Hell yea, the peanut generation is the damn best. At least you can still get the forged build engines, the ej207 is still a new short block option to buy. Remember when they used to factory close deck too?
Nope. The 207 has forged pistons, (v7 gen), lower compression ratio, semi closed deck and can rev higher. And costs the same to buy as a new short block. Bought as a complete long block motor the sti will cost more.
Hello Brett, Can you make a series of videos that pertain to regular Subaru motors? I have a used 2004 Subaru Forester X 2.5l SOHC w\ Auto Trans that was abused in terms of oil and trans fluid changes and basic maintenance and I want and I have to do a basic re-seal to keep it going and learn from it but I stress over what the kondition of the motor will be after opening it up watching this video. I have to live from this car and so far have not been able to get a car of any type donated to $400 like I got this car so any projeckts I have to open and klose the project each day. I tried to get to you via phone and internet but phone return displayed permanently closed and internet said you wern't safe that you were not https qualified.
My ej251 is at 235xxx miles. Every single gasket is gone and is on its 2nd failing head gasket. I have blow by and compression loss and carbon build up on the rings. No catch cans so it goes into the intake and exhaust. That engine still runs. Subaru is a different company now run by different breed of people.
Pfft my ej251 is at 254k. On its 2nd head gasket has 13% ring blow by on all cylinders burns a quart of oil every 500 miles no catch cans and I turbo charged it with a wrx td04 on 5psi with a voltage clamp and 10:1 fmu and it was a freaking fun ride till I blew a ringland in cyl 4 130psi compression then went another 600 miles and I finally blew it lol. Now I'm doing a 255 hybrid block with my 251 heads
Took a long drive with my Subaru for about an hour then came to a stop and got a check engine light and misfire check engine light was PCV blow by! Car pulls the same and no decrease in performance, so I just vented the PCV to atmosphere and runs better. Mines a hybrid build and I heard they have blow by problems
I've got a franken-engine too, an ej257 block with ej20 everything else. Best part is when you have the ej20 sump you don't need to worry so much about cracked pickup tubes. And your comment got me thinking, I did have a custom catch can fabricated and I installed it to filter the top of the crank T, which is crank case under boost venting, but after quite a while there was almost nothing in the can. I then peaked at the side tube that is vent under negative manifold pressure through the pvc under the throttle body and it was very wet with oil. So I've switched them around and haven't as yet had a misfire code. It was always cylinder 4 misfire, and it happened while the car was still cold and warming up, so after the car was sitting all night and light loads. Once it was misfire all cylinders. But yea, it wasn't too common, probably about 4 times last year, but I just think you're on to something. Get a catch can. :)
This happened to me and the first sign I should’ve looked into was how dense and how much white smoke I was getting. A lot of freaking smoke and I kept telling myself that it was just the tune
I will say that this is a benefit to the ej series is that you can find the problem before catastrophic engine failure vs my fa motor that will be just snap a rod and grenade the engine.
The ej20s are much better stock for stock at handling power. My ej205 has been at 23 psi and 350awhp for about 10k miles and before that at 20 psi 315whp for 15k and then 19 psi and 245whp for about 80k miles. It has 160k miles on it now and no blow by and solid compression.
At 75k. COBB Stage2 for about 2 years; using very little to no oil at all between changes and excellent maintenance. Just had a new OEM wire harness install, then the WRX overheats badly (& p0117), for the first time ever. Stopped and cooled it, seems fine...but just to be sure went to Subaru, and they say blown head gasket; though I never noticed any loss of power. Waiting to hear any day about the pistons, etc.
aint that the truth...the local dealer here knows how to gouge you for reprogramming tpms modules, oil changes and such but if you have real trouble you are on your own.
Hey, I was thinking of getting a subaru but there aren't any shops specialized in Subarus where I live. I've already read a lot about the EJ25, if I get one first thing I would be doing would be the safety upgrades such as AOS, cyl 4 cooling mod, equal length headers and killerB pickup tube. The thing is, is it worth getting one if I don't know how to do the maintenance myself and there aren't specialized shops for subarus near ?
thanks for your feedbacK :) can you give us support here and re share your comments? www.google.com.au/?gfe_rd=cr&ei=qvzuWJWwL4Xr8wfl65KACQ#q=mrt+performance&lrd=0x6b12a4fda1446c67:0xd977a8763eea40f2,1,
Some other people say why waste money on subaru engine? Why? Because we like the characteristics of the engine the sound of ej the classic rumble that engine give and most of the power delivery that motor produce sure it's not fast just like an evo but we love the engine even though it have in perfection (ringland) nothing more nothing less.
I really wanted a STI hatchback, are there any models without this problem? What if I had a shop replace the rods and pistons to avoid OEM piston failure? would it happen again then. I'm not one to trash a car just have a little fun getting on the on ramp etc.
Nathan Pieroz same here. Regular oil changes, proper warm up/cool down. Have done a couple of track days and feels just as good as they day I bought it.
Love the video's. I am looking at getting a n/a ej20 or ej25, i'm not looking at a full build just yet just basic mods to start. What would be your recomendation for a high revving n/a ej with power?
I have my 12 s edition WRX and it is having issue of burning oil. I only bought it in April with 80,000 on the clock. It is tuned to Cobb stage one. I took it for first service to WRX specialist in Melbourne and asked him to have a good look and notify me of any abnormalities with the car and they did the service and found no oil in it and he told me that the motor sounds bit off beat and they found some glittery stuff. any ways been taking car back and forth to the dealership, they been topping up the oil now it was the fourth time I took it there and left it and told em that m not picking it up unless they are going to fix the issue. See what happens next. Can you suggest something? Would it be something similar like this? Lucky I bought 3 years extended warranty on it.
Can this issue appear on a stock 2007 EJ253 out of an Outback with 124k miles? My car uses a quart of oil a month, it doesn't leak anything on the ground and the bottom of the car is totally dry.
I have an 06 hawkeye N/A ej204. I bought it recently in very good cond with 106000k's. It has gone well for a few months but now has a slight hesitation at 2900rpm. There doesn't seem to be miss when this happens, just a slight hesitation for a second or so. I did recently run the tank quite low.(light was on for about 5k's) It idles perfect. From what I have read it sounds like the VVCS sensor? Any ideas would be greatly appreciated and may gain you a customer. I don't want to replace heaps of parts on spec. I want it fixed the first time. thanks.
I have a 2011 Bone Stock WRX. I kind of want to try an accessport stage 1. Would I run into a possibility for failure if I do this? I change the oil every 3000 miles.
So how much would ut cost just to fix that ringland issue with really good parts?? Also does the ej25 have any other major issues? Just wonfering because i live up high in the mountains. 5000ft above sea level & am looking for a fun turbo car. Evos are nice too
I'm using RVS triboceramic treatment in my stock XT EJ25 and it noticeably smoothed the engine and gearbox. Gear changes became tighter, engine smoother. Any experience on that down under?
So my oil needs to be refilled every 2 weeks, you can smell it burning and there is smoke from the oil fill cap. If I keep putting new oil in it, will it last longer?
F in chat for my rig. Just went to get my car tuned, only to find that I have ringland failure in one of the pistons and essentially will need to fork out big cash for a rebuild.
Dear Bret, I understand that good fuel, a good 3 port oil catch can, regular servicing (oil changes + spark plugs) and sensible driving all help lower the risk of ring land failure. Is there anything else you can advise on reducing the risk? Or shall I start saving for forged Pistons now? Lol many thanks
ScoobySTI Chris the things that crack the ring lands are the rings butting against each other during high boost/high heat situations. Open up the ring gaps and the engine will live a a lot longer. GM LS engines do the same thing, that's why boosted engines get the ring gaps opened up or a real high mileage engine is found ( they don't get race ready until after 100,000 miles )
ScoobySTI Chris yes buy an evo fix the problem every time. This coming from someone that owns a 100% stock 2015 sti. And I'm going on engine number 3 for ringlands. I love this car but right now I wish I got a fucking evo
the cost of the car. New, presumably. He ain't wrong though. I love the STi, it's like the last of the OG tuner cars from the mid 2000's. But the ringland problem is absolutely unacceptable. I wouldn't recommend a STi to anyone if they didnt have around 7k in the bank to build the motor after it goes.
@@nemui_tora hay mate u seem knowledgeable, i have a 99 evo 4 it's running out of oil every 4 months. Could this be ringland failure or just the age of engine? If there was oil leaking would there be oil built up around the engine?
Patrick Ervin I want to say only when modded and over boosted. My 2016 WRX always had those boost spikes around 21-22 psi when the weather gets warm due to the mediocre factory tune.
My '15 WRX is 3" from air filter to exhaust tips; Stage 2 E30 custom tune 22.7 psi @ 350 bhp. Top of the mark for these little con rods. Don't want Rodney to come out to see me 😖
I might buy a 2008 Subaru WRX STI any day now. It has 12 000 km on it. However the engine is brand new and only got 1200 km on it. The whole car is stock. Will I have any issues?
Love your videos Brett, just wish I had all that knowledge. Question, if you can offer some advice? I have a 2017 STI (stock engine) & considering the GFB Respons TMS BOV (or Turbosmart equivelant). I'm just looking for some sound for now. I've read this mod wont require a tune, would you agree with that? Also would it be safe to run the valve open/closed in most conditions without issue?
question for anyone who might see this even though this video is super old. I've got a 2013 STI and I almost got stuck in some really wet snow. the only way i was able to get the car to move was by getting it near red line. the rev limiter stopped it from going over red line but i had to run it right under 7k rpm for a good 30-45ish seconds. I haven't noticed any major oil consumption but I've been paranoid about it ever since and can't even drive the car enough to monitor oil burn due to the pandemic. Anyone think i should be worried about ringland failure? Thanks in advance!
I wonder how this applies to a naturally aspirated FA20 on a BRZ. One day when I'm rich I want to boost my car, but before that I'll build the engine up with forged internals and all that stuff
Have you seen this happen with forged pistons? 25k on my rebuild and all of a sudden I’m burning oil like crazy. It’s burning about 2 quarts in 3k. I have to add oil to my sti every other oil change. Any help on this would be amazing. Thank you
My NA forester from 2012 has major oil consumption issues. Could that be ringlands? I'm confused because it's obviously not boosted and doesn't see extreme temps. Bad rings?
canchume nope, it will leak eventually. Either internally, which is hard to notice. Or externally which will start as just an oily residue on the bottom of the block right where the heads meet up. Single layer inferior gasket design. The only real fix is new gaskets. Fel-pro makes a good one. It can be done with the engine still in the car but it’s a little more challenging. About $1,700-$2,000 to have a shop do it in the USA.
So with a bone stock 17 sti that had its oil changed with subaru oil only and is driven hard. Will it last? 23,500 miles and it's perfect. I hope to drive it hard and have it still last. I never lug the engine or floor it below 3500
Sherie my friends with CVT does as well, it sounds like its very light and on the complete edge of detonation, but honestly Im pretty sure this is just normal noise.
Won't stop the oil consumption, every car consumes oil, but if you install such a thing, don't get one of those return to sump aos systems that have the pretty thing sitting on your filler tube for example, they'll just fill your oil with water. The humble mechanic has a latest video showing him emptying a catch can, you'll be surprised at what pours out, and a return to sump aos, all of that is what would be going back there.
Ok now wonder my subi is burning so much oil, 1 month after an oil change the oil level went down to half way, some people were telling me it might have been a bad turbo deal but I'm pretty sure it's the rings after watching this video, I appreciate what your guys do at MRT, quality videos wish I would have found you guys sooner, does anyone know how much would it cost to replace piston rings? I'm planning on building the EJ25 in about 2 years after I graduate college so I'm not sure if I should wait till then, or replace them now. I don't run the car hard, but one time I noticed smoke come out the exhaust when I did a pull in second gear, i was at about 6k rpms
3Revs it not just pistons. When you go to build there will be a lot of little shit you should replace. Timing chain, oil pump and so on. Around 8k to rebuild and that's not with a turbo or anything
I have a factory original 2006 STI with no modifications and have never tracked it. Is it still likely to suffer ringland failure without any engine mods?
Not likely. What oil are you running, and how often do you change it and check it? How much do you add between changes? Have you had the compression tested? Do you do any oil analysis? I have a 2007 that has 115k miles and has been stage 2 for about 75k of them. No issues.
Ringland Failure is WAY LESS LIKELY when the car is actually tuned PROPERLY, any tune is better than stock, it’s actually more likely to break a piston STOCK, it needs an AOS, and Tune, period.
i should have not clicked on this before trying to go to sleep
Ian Irizarry me too bro. Sigh.

I cracked a ringland in my stock ej257. Now i have a fully built motor that has been putting out 404whp for over three years now.
horses not found
Violetta omg, I'm mad at you for that one.
Violetta says my car never
maxxjett films 404whp from a built Subaru? My old Evo 9 made close to 450whp on stock turbo and engine on E85. 🤭
Pennywise my 404whp is with 91. There is more on the table with e85

Brett for Prime Minister!
So in short, if you do do a intake, and exhaust upgrade with proper tuning and dont flog it, ringlet failure is potentially avoidable.
Bart Majic People’s main problem is modding it without a tune . You have to tune it each mod .
I think the best thing to do is aftermarket pistons and rods. Then modify for power.
Hi Brett can you please consider doing a video on air oil separators and information on them/ installation instructions. I think it would benefit everyone considering how beneficial AOS’s are for Subaru’s.
Remember the good old days when Stis had forged pistons and WRXs had limited slip differentials.
Hell yea, the peanut generation is the damn best. At least you can still get the forged build engines, the ej207 is still a new short block option to buy. Remember when they used to factory close deck too?
MV60 isn’t the ej205 just as good but cheaper
Nope. The 207 has forged pistons, (v7 gen), lower compression ratio, semi closed deck and can rev higher. And costs the same to buy as a new short block. Bought as a complete long block motor the sti will cost more.
you gotta have some serious balls to wear an apple watch in a machine shop
WC Moffatt he’s the brains of that facility. Check out his hands, super clean. Lol.
My 2014 Wrx doesn’t sip a drop of oil. 100k on the lot. Has been a nice car.
So basically, you let the car decide when it wants to have its birthday.

May wait for the 2020 sti

It's not a failure of the motor. It's just motivation to build it. Lol

I will say that this is a benefit to the ej series is that you can find the problem before catastrophic engine failure vs my fa motor that will be just snap a rod and grenade the engine.

HAHAHAAAAA! Andy Forrest gets a mention as he ragged the Whiteline STi at a WTAC test day :)
In the motors I deal with that is from detonation, often makes rings break. The 2019 still is all forged parts I am told. ? not sure on that.
For subaru motors being made after all these years they still have many flaws

I have a 2011 Bone Stock WRX. I kind of want to try an accessport stage 1. Would I run into a possibility for failure if I do this? I change the oil every 3000 miles.
I have a 2015 sti. With 90k miles I been eating 3 quarts of oil in between oil change sence 50k mile.
So how much would ut cost just to fix that ringland issue with really good parts?? Also does the ej25 have any other major issues? Just wonfering because i live up high in the mountains. 5000ft above sea level & am looking for a fun turbo car. Evos are nice too
I'm using RVS triboceramic treatment in my stock XT EJ25 and it noticeably smoothed the engine and gearbox. Gear changes became tighter, engine smoother. Any experience on that down under?
Hey man im interested in this. Any links?

Coolant mod prevents this. Checking oil prevents this. Equal length headers prevents this.
Yeah my ring lands are dead 3 quarts in 1500 miles ... 😐
I’m breaking in my closed deck block. My compression is 120 across and 2 to 3 percent leakdown per cylinder. Should I be worried?
So my oil needs to be refilled every 2 weeks, you can smell it burning and there is smoke from the oil fill cap. If I keep putting new oil in it, will it last longer?
F in chat for my rig. Just went to get my car tuned, only to find that I have ringland failure in one of the pistons and essentially will need to fork out big cash for a rebuild.
Funny how this video came up in my recommended feed just as my ej205 has started consuming loads of oil.. 1 Liter / 200km's.
Jesper K normal it’s to make power lol
Excellent information and presentation, Mr. Middleton. Thanks!
Dear Bret, I understand that good fuel, a good 3 port oil catch can, regular servicing (oil changes + spark plugs) and sensible driving all help lower the risk of ring land failure. Is there anything else you can advise on reducing the risk? Or shall I start saving for forged Pistons now? Lol many thanks
ScoobySTI Chris the things that crack the ring lands are the rings butting against each other during high boost/high heat situations. Open up the ring gaps and the engine will live a a lot longer. GM LS engines do the same thing, that's why boosted engines get the ring gaps opened up or a real high mileage engine is found ( they don't get race ready until after 100,000 miles )
Steve Ross thanks Ross, so what your saying ring land failure has nothing to do with ‘knock’ caused by heat, low octane fuel etc etc ? Thanks 👍
ScoobySTI Chris yes buy an evo fix the problem every time. This coming from someone that owns a 100% stock 2015 sti. And I'm going on engine number 3 for ringlands. I love this car but right now I wish I got a fucking evo
Why does ej25 engine have rod bearing failure?
Thinking about getting a 18' Crosstrek, professional opinion engine/transmission wise on those?
Damn spend 40,000 for a engine to go at any moment. 😕
WHere da fuk do you come up with that figrue? 40K
the cost of the car. New, presumably. He ain't wrong though. I love the STi, it's like the last of the OG tuner cars from the mid 2000's. But the ringland problem is absolutely unacceptable. I wouldn't recommend a STi to anyone if they didnt have around 7k in the bank to build the motor after it goes.
@@nemui_tora hay mate u seem knowledgeable, i have a 99 evo 4 it's running out of oil every 4 months. Could this be ringland failure or just the age of engine?
If there was oil leaking would there be oil built up around the engine?
2018+ pistions are different, a decade later they're fixed
Does the fa20 in the wrx’s have rod problems in a stock setting or just under modified circumstances?
Patrick Ervin I want to say only when modded and over boosted. My 2016 WRX always had those boost spikes around 21-22 psi when the weather gets warm due to the mediocre factory tune.
It's modified. Why I won't go bigger turbo unless I build the motor.
My '15 WRX is 3" from air filter to exhaust tips; Stage 2 E30 custom tune 22.7 psi @ 350 bhp. Top of the mark for these little con rods. Don't want Rodney to come out to see me 😖
I might buy a 2008 Subaru WRX STI any day now. It has 12 000 km on it. However the engine is brand new and only got 1200 km on it. The whole car is stock. Will I have any issues?
thats not a question we can answer, we always strongly suggest any car purchase gets an inspection.
the BIG QUESTION is WHY does it have a new engine?
Love your videos Brett, just wish I had all that knowledge. Question, if you can offer some advice?
I have a 2017 STI (stock engine) & considering the GFB Respons TMS BOV (or Turbosmart equivelant). I'm just looking for some sound for now.
I've read this mod wont require a tune, would you agree with that? Also would it be safe to run the valve open/closed in most conditions without issue?
3 years and still waiting for all those anwers lmaoooo
question for anyone who might see this even though this video is super old. I've got a 2013 STI and I almost got stuck in some really wet snow. the only way i was able to get the car to move was by getting it near red line. the rev limiter stopped it from going over red line but i had to run it right under 7k rpm for a good 30-45ish seconds. I haven't noticed any major oil consumption but I've been paranoid about it ever since and can't even drive the car enough to monitor oil burn due to the pandemic. Anyone think i should be worried about ringland failure? Thanks in advance!
I wonder how this applies to a naturally aspirated FA20 on a BRZ. One day when I'm rich I want to boost my car, but before that I'll build the engine up with forged internals and all that stuff
Was this failure on piston number 4?
Have you seen this happen with forged pistons? 25k on my rebuild and all of a sudden I’m burning oil like crazy. It’s burning about 2 quarts in 3k. I have to add oil to my sti every other oil change. Any help on this would be amazing. Thank you
It happens with any piston. If your car is running like poop. It’s gunna blow up.
My NA forester from 2012 has major oil consumption issues. Could that be ringlands? I'm confused because it's obviously not boosted and doesn't see extreme temps. Bad rings?
Steven Oswald it is
You are great! Greeting from the United States
i have my legacy with the ej251 i just bought it with 132k miles and no problems with the headgaskit , any recomendations to keep it tha way ?
canchume nope, it will leak eventually. Either internally, which is hard to notice. Or externally which will start as just an oily residue on the bottom of the block right where the heads meet up. Single layer inferior gasket design. The only real fix is new gaskets. Fel-pro makes a good one. It can be done with the engine still in the car but it’s a little more challenging. About $1,700-$2,000 to have a shop do it in the USA.
So with a bone stock 17 sti that had its oil changed with subaru oil only and is driven hard. Will it last? 23,500 miles and it's perfect. I hope to drive it hard and have it still last. I never lug the engine or floor it below 3500
xxnissansilviaxx i never broke in my motor in my wrx and motor lasted all the way to 45,000 within 18 months before i totaled it
25k on my 2014 WRX no oil consumption yet (fingers crossed)
Our 2.5 XT has what sounds like very slight pinging at small throttle openings. Goes away with a bit more throttle. Imaginitis ??
Sherie Thomas bad fuel maybe
don't buy the lowest octane / cheapest gas. At least put 91 (USA) octane through it, especially the turbo motors.
Sherie my friends with CVT does as well, it sounds like its very light and on the complete edge of detonation, but honestly Im pretty sure this is just normal noise.
so get a older 2 litre turbo? are they better than the 2.5 ?
Do you have to turn the car on its side to do a leak down test ? Lol
LOL!
Max Hp Tq recommended on fa20dit and max boost for safe tune ?
so is this also common with the ej20 sti motors?
Enjoy the videos thanks.
My 2005 LGT eats oil, its stock, but no aos or catch can. Would either of those help?!
Won't stop the oil consumption, every car consumes oil, but if you install such a thing, don't get one of those return to sump aos systems that have the pretty thing sitting on your filler tube for example, they'll just fill your oil with water. The humble mechanic has a latest video showing him emptying a catch can, you'll be surprised at what pours out, and a return to sump aos, all of that is what would be going back there.
Ok now wonder my subi is burning so much oil, 1 month after an oil change the oil level went down to half way, some people were telling me it might have been a bad turbo deal but I'm pretty sure it's the rings after watching this video, I appreciate what your guys do at MRT, quality videos wish I would have found you guys sooner, does anyone know how much would it cost to replace piston rings? I'm planning on building the EJ25 in about 2 years after I graduate college so I'm not sure if I should wait till then, or replace them now. I don't run the car hard, but one time I noticed smoke come out the exhaust when I did a pull in second gear, i was at about 6k rpms
3Revs it's not a bad turbo its ringlands. I hoped mine was turbo to. But I been drinking 3 quarts every oil change for 30k miles. Just keep oil in it.
3Revs it not just pistons. When you go to build there will be a lot of little shit you should replace. Timing chain, oil pump and so on. Around 8k to rebuild and that's not with a turbo or anything
Excellent video(s)!
no problems with an ej207. no ring failure :>
I have a factory original 2006 STI with no modifications and have never tracked it. Is it still likely to suffer ringland failure without any engine mods?
Not likely. What oil are you running, and how often do you change it and check it? How much do you add between changes? Have you had the compression tested? Do you do any oil analysis? I have a 2007 that has 115k miles and has been stage 2 for about 75k of them. No issues.
Been stage 2 tuned for 50k miles now in my 07 sti. No issues. Normal oil consumption still. Tuning and monitoring your oil is key to longevity.
Mr. AWDriver and of course don't lug the engine!!!!
The girl on the poster behind his shoulder hahah
Typical Aussie garage office equipment.
who fucking cares.
Do you have any friends over here in the States? I was wondering because you guys are so knowledgeable but you're so far away!
Brett, will the AOS or oil catch can help prevent this failure?
AOS is for oil ingestion, this is normal for all engines, so no it wont help
Thanks for the reply!
If it is not helpful, then what else can we do to help reduce the chance of ringland failure?
ringland failure is a whole lot about how the car is driven and how and who modifies it and their knowledge of ignition control
;)
So to avoid this, get a proper tune and make sure to Install Front Mount Intercooler and a boost solenoid?
not necessarily..........
the piston failure is a Subaru weakness that is accelerated by poor mods and poor tuning
a FMIC wont eliminate that
:(
Ringland Failure is WAY LESS LIKELY when the car is actually tuned PROPERLY, any tune is better than stock, it’s actually more likely to break a piston STOCK, it needs an AOS, and Tune, period.
How bout a ej253? 2.5i?
So does a cracked ringland only happen if you run your car out of oil?
CarbonCrossroads no it just happens but it will still run if you keep oil in it. With bad ring it will eat up oil fast
ak47 ah gotcha.
When a manufacture knows the problem but does not fix it is a total slap to the face for brand loyalist,
aaron monke blame emissions. The only reason they use the hypereutectic pistons is to cut down on cold start emissions. They used to be forged.
