Deny this! ,|,,
Yea a mate of a mate
bought a new 2017 RS, engine failed with the coolant "issue", it had hydrolocked on its own coolant! so had it replaced under warranty, he asked ford for something back in writing to ask if that the new engine had been changed in anyway or some kind of assurance that it wouldn't fail again, they just sent him back to the dealer, dealer sent him back to ford lul, I told him, ford will never give him what he wanted in writing, and you guessed it, it has failed again! HG this time and the mechanic believes the block maybe warped too. Its back in again for its 2nd complete new engine. This car has never been tracked or launched and treated like a newborn baby from day one, its just a daily. 1st engine did 15K before it popped, 2nd engine failed after 5K, total joke. He does a lot of short stop/start journeys, this is why he's been so unlucky, as its an issue with cold/hot starts warping the head/block.

Having owned a MY11 STI 320r for the last 8 years and done 108k Miles in it and followed may forums I think a lot of the failures are down to bad fuel or not keeping an eye on the fluid levels. Mine has used oil from day one but always kept a keen eye on it serviced to the book and more importantly only ever run on shell v-power.

Nice to know pal I always keep an eye on the fluid levels and cool down and warm up as it should be done , I hope to god this is a strong reliable car with hardly no issues in the future ha

Or look out for a used forged engine as long as it's history can be traced like who built it etc and what was done.
Also do your research on who you use to work on your car, plenty of so called specialists around that don't know their **** from their elbow.

Between £3k and £4.5k depending on spec if you wanted to push more power etc

i do find it amusing how people still seem to think one version is better than another (seems to be typically what they have funnily enough lol).
Simply put its pot luck, i know cars that have been treated like crap and have over 100k and i know cars that have been babied that have died in less than 10k.
Good servicing, run them on proper fuel and your doing as much as you can, beyond that its just pot luck.

Hi guys, new member here. Recently purchased my first Subaru, a 2008 STI PPP with about 87.000 miles and full service history. The car is always run on Shell V-Power. Doing some reading online I came across this thread and it's scaring me a lot. Having paid so much for the car it's now always on the back of my mind wondering if/when it's gonna go. Not to mention to forge it is about 5k which is money I currently don't have as I'm still paying the car.
This thread began with fairly new cars and brand new ones that failed after a few thousand miles.. Do you think that a 2008 that has lasted up to 87k miles without that issue might not have it at all or are all they prone to failure no matter the mileage that they have already endured?
I'm really questioning my decision now and it kinda prevents me from having fun with the car.. :\

Hi and welcome.
In short yes, all the 2.5 engines have the potential to fail no matter how new or old as they all have the same potential part defects and build faults that cause the ringland and head gasket failures.
With that said, don't worry about it too much. I've owned 2.5 engine Subaru's for the last 10 years and haven't suffered a failure yet. The 2.5 Subaru engine makes for a lovely daily driver on the roads. I love them.
The factory ECU map won't help, so I would say at the least get your car mapped by a reputable tuner ensuring the boost is kept below 1.35bar max.
Other than that just enjoy it and tuck £3.5k away just in case!

Hi and thanks for the info! If I'm correct the Prodrive Performance Pack includes an ECU map according to the PPP brochure: https://impreza.co/wp-content/upload...P-Brochure.pdf
Is this a good thing or bad for this specific issue?

I wouldn't have said an oil separator was essential at all Matty to be honest.
With regards to the Prodrive map, in my opinion it's still a generic "one size fits all" type of ECU plug in map. It's not tailored to your car, your cars sensors, fuel grade, engine etc.
If it were my car and money I'd still get a professional to do a bespoke map.

I know a guy his 330s on 90k took advice on here and got a remap wasn't long after it went bang, and that was by one of the best mappers in the country.
My advice it's not broke so don't fix it, just enjoy it there great cars.

Do you know who the mapper was and what the peak boost was set to on the car? Was the car well serviced and cared for or driven like it was stolen?
I always monitor my peak boost, air fuel ratio, water temperature via an ECU diagnostic port sender and android app into my dash mounted display. It's well worth doing on these cars. It picked up that the change of my exhaust was making my car over boost and needed a remap before I got head lift and head gasket failure.

my car was bone stock too , there are some things would can do to prevent it tho ,, go wot at low rpm ie below 4K puts huge amount of strain on the pistons ,, don’t bolt on anything with out a remap ,,, get a retune this way they can check the knock and afrs are correct , don’t go more than 2psi over standard boost pressure , and get an air oil separator , the 2.5 is quite sucky lol and oil in the inlet will cause detonation so a must for standard engine ,, and also the standard turbos like to crack I had mine changed at 67k because of a crack by the wastegate
