No Head Gaskets- it was a big problem on the 2.5 in particular.

'Apparently' in America.
Who what where?

Most of failures that I know are due to Ringland#4 going bad due to crap stock ECU tune leading to detonation in Cylinder4.

just bought one and naturally I don't agree

have had a number of Imprezas and the new Leg carries on the good work

certainly moves the quality bar forward and a good balance of scooby classic features' 4wd, form over function etc plus nods to things that have moved forward; like decent ICE.

so this week I saw legions of merc, beemer and audi estates, chelsea tractors by the score and not one new legacy.

Does anyone know if it has unequal exhaust manifolds? They don't really sound very good unless they do and I think it would take a lot of the character away from the engine. I know some of the later JDM EJ's had equal length.
If they come with equal length headers, I'd give it about 2 weeks before aftermarket kits are available.

I don't think Subaru would go with equal length headers except on the pure performance-biased special editions, as in the past. Subaru know what their customers like about their cars, and the burble from the unequal headers is one of those things that define the brand.

It will be interesting to see how it goes - they've gone to a longer stroke and smaller bore which I hope doesn't make the performance versions less rev-happy.
Sounds like they are still pushing for the mass market again by trying to make it more torquey, usually if they want to get more out the engine the bore goes up and the stroke down. You harly see any new impreza's on the road so i don't think its what people want.
More what?

More torque generally comes from engines with a longer stroke, narrower bore, longer throw on the crank, the definition of torque really.

But in the days of hybrid and twin scroll turbo's, and the older Legacy's were twin turbo's, there isn't really a need to produce more torque in this way imo. Modern turbocharging technology can deal with the low rev torque much better than in '89 when the EJ20 appeared.

My Impreza was a big laggy, and didn't make much boost pressure til about 3000rpm, our new turbo MINI, completely different story.

So i hope the engine doesn't loose those evvy characteristics. That said, when i had to take the lightened flywheel off mine and fit a standard one, it did kinda ruin it a bit for me.
I mean that if they are going for more power then usually you have shorter stroke and bigger bore. By doing what they have done i'm think the engine will lose its revvy nature. I had been on the pop last night and wasnt that clear what i meant. It's a shame the impreza has gone the way it has.

Re: Impreza turbo reliability...

Cars which are kept standard and used in their respective home markets are massively reliable. Modified and those used in different markets to those sold in? You're on your own.

Thats the case for pretty much every production car. For modified impreza turbos so long as you tune the car properly (no knock) and make sure the oiling to the engine is good your car should be reliable even with modifications.

Subarus may not be the most effiecent cars in the world, but in terms of gerenal reliability they are far better than the likes of BMW, Audi, Volvo.

I am chopping in my XC90 for a Tribeca next week. Over the year i have still calculated that a Petrol Tribeca will be cheaper to run than a Diesel XC90.

XC90 gets no more than 26Mpg. Tribeca will be around 17Mpg. But the big difference is servicing. over 3 years of ownership and 6k miles per year. The Volvo servicing comes out to be £2200 at main dealer. where the subaru comes out to be £700 at the main dealer. I do not expect anything to go wrong with the subaru but running a XC90 is like running a TVR expect another £1000 worth of repairs come service time!

I am glad that Dubaru are sticking to there roots and updating the Boxer Engine.
There speaks a man who hasn't factored in depreciation! A Tribeca - you're brave!
Am I.. I am getting a 07 plate se7 fully loaded for less than 10k.

I hope they employ a new team of designers to go with the new engines. Im sure no one knows more than Subaru how badly they cocked up the Impreza's design (through lack of sales).

But more recently they have also managed to completely destroy the sleek smart understated look the Legacy which in my opinion was the smartest looking Jap family saloon on the market, not to mention what they did to the Forester....

So please Subaru, lets get the priorities sorted, (also a return to wrc would be nice)

Well said. Having just spent £3k on a seized engine I completely agree.
What engine/spec etc was it? What happened??
It's a 54' plate outback (new shape) and it had got to 99,900 miles! and always serviced at my Subaru dealer.
Due to usual Subaru oil pump problems and the need for a new radiator the oil was being boiled but not showing on any lights on the dash. It was explained fully to me by the guys at API engines but I'm not the most mechanically minded. API were fantastic BTW. Drives like new now and all is well.
To try and reduce the pain I pretended that when I picked it up it was a car that i'd just bought for £3k and that made me feel much better.......
Doshy,

Is there any way to avoid this problem; any preventive measures?

could not agree more, i have two a 58 plate diesel and a 54 plate 3.0 b spec, very handsome cars, massively capable on road, and not the same old merc, beemer or audi,

i have also driven all the german cars and the Subaru is far more enjoyable and agile

I think the reason you don't see many Imprezas about is because they look like st and they aren't very good either.

I do think it is great that they are sticking with the boxer engine but until they get some decent designers in they are on the path to bankruptcy.

The last Legacy was a sweet handling car with a combination of good handling and good ride quality that few mid size cars could match. It looked pretty good too. However fuel economy was rubbish until they introduced the diesel boxer engine, by which time the design (and in particular the interior) had dated.

So once they'd got the engine right all they had to do was update the design and up the interior quality. Then they go and produce the monstrosity that is the latest Legacy. It is just gross and so it won't sell. Like I said "a path to bankruptcy". What a shame.
Not sure about UK but at least in the US markets Subaru and Hyundai were the only 2 car manufacturers to show an INCREASE in sales during the peak of recession in 08-09.

eek - there is no way to spot a oil pump problem is there?! If it happened to mine I'd be in two minds about throwing 3k at it.
Spotting oil pump going bad is very very easy ... your engine will spin a bearing pretty much at the same time the pump stops working. :P

A set of ricer A'pexi oil pressure & temp gauges might help?

Closet Subaru admirer, so I hop they get back on form ASAP.

Actually, a 10% improvement's pretty good, given the emission requirements and no mention oftrick valvegear. Most modern Honda engines have depressingly long-stroke designs too. I think it's inevitable these days, sadly.

The pressure relief valves can stick open. There's a 'step' on the valve, or the sleeve, that causes it to catch. The uprated pumps have this bit sorted out. Also, the bolts that hold the pump to the block can work loose over time which also lowers the oil pressure. Most specailists retighten the bolts at cambelt change time, or when changing waterpump, tensioners, pullies, etc., and also add Threebond 1215 over them for a bit of extra security.

That said, it is rare for the pump to fail, albeit possible.

Can get Cosworth pumps, or refurb'd/modded OEM ones from the likes of API, RCM, GGR et al...

You'd only notice low oil pressure if you have a decent oil pressure gauge fitted. Otherwise, as said, until a big end bearing spins; at which point it's too late! lol

just a quick note in favour of reliability,..

I've had 5 Scoobys, and done on average 90K in each of them, I am on my sixth, and that has 80K on it, all in all over 13 years, 1 engine seal, 3 wheel bearings, and some oil,..

That is what I call reliable!

How? Sound/symptoms etc?
Spun bearing is a pretty catastrophic failure. Heres a video of your engine will suddenly sound like along with a host of CELS.

Like someone said ... invest in good set of Oil pressure gauges like Defi, Autometer, prosport.. Also, if you are doing major upgrades to your engine then invest in a upgraded oil pump like Cosworth oil pump and a new oil filter.

hi the spec B has the Bilstein suspension, 3.0 flat 6 and is more sporty than the standard 2.0 or 2.5, i have seen a 3.0 re i think, but not sure on all the differences, main is the suspension being Bilstein.

Can anyone recommend a good Subaru specialist as close to Leeds as possible? I don't mind travelling anywhere at all, but obviously if there's a good one in Wakefield and an equally good one in Brighton, I'll be visiting Wakefield.

The reason I'm asking is that I'm new to Subarus and I'm considering a 55 plate WRX with about 40-50k on the clock, and I would like things like decent oil pressure gauges fitting by someone that really knows their way around Imprezas.

I'm on my 4th Subaru (over 9 years and more miles than I care to count) and other than routine maintenance I've had 1 MAF sensor go (car wouldn't start), 1 MAP sensor (only 7psi boost until fixed), and 1 split radiator hose (on a 15 year old car).

So I agree with you on their reliability!
