2.5 Head Gasket or Ringland Failure Poll
 

Poll/thread for fellow 2.5 owners to see if they have had either of these fail. We all know it happens... just be interested to see what scale of SN user's have suffered.

Fill in the poll and then reply with year of manufacture, car spec, the failure and the rough mileage on the car when it happened e.g for me...

2006 - Sti Spec-D - HG Failure - 43k

2006 - Sti Spec-D - HG Failure - 43k

To make this fair, you should really add the option "no issue" to each year model option.

My Spec D PPP failed at either 38K or 48K - I can't remember off the top of my head. The car was three years and six months old and had been fully serviced seven months previously.

It was a HG issue and that was believed to have caused ringlands failure of no. 4

should add another to the poll - * touch wood everythings fine

then you can see the percentage of fails to non fails

There's already a pinned thread about this. Isn't that enough to de-value and scare people away from buying secondhand 2.5's ?
I would like to also see some info on the 2L engines that have failed. I know of a few that have blown head gaskets, cracked or porous heads or spun shells.

But.. 2007 RB320. #2 & #4 piston ringlands @ 21K car was modded running 360 bhp.
Now runs lovely thanks to Finch Motorsport working his magic.

+1

As far as I am aware a specialist in Leicester repaired an unmodified 2010 Spec C hatch that had blown its head gaskets.

A JDM car previously in my extended family had a pretty impressive engine failure a few years back too.

Still, would appear that they're less temperamental and more reliable than German cars!

Agreed but I don't seem the be able to crack it open again to add that... my bad but still might be interesting.

I take your point... and while I agree about the scare mongering you have to admit it sucks monkey balls when it happens to you so I can't see the harm in giving people the information to make an informed choice. Lets face it if people want a Hawk/Hatch they will get one regardless. I knew the risks and I did it anyway (while looking very carefully for hg signs). Even with a thread like this i'd do it again probably but i'm lucky enough to have some repair funds.

We can always set up a matching thread for the 2.0's? I'd be just as interested myself.

2006 Spec D PPP - HG failure at 55k (signs of failing HG since 45k)

I'm not so sure there would be many 2L or JDM owners who will admit or disclose info in public. After all they are very successful in talking up their cars and raising their value and appeal. A few on SN as i see it are guilty of blatant market manipulation :lol1:

In fact i would have liked this to have been a public poll. That way we could see the member that voted. There is nothing to stop members voting they have had issues while never owning a 2.5.

Another Spec-D failure... 300 made how many melted! If still own it and havn't already join the Spec-D thread mate (bottom of my signature).

lol i love the 2.5 owners trying to convince themselves the 2.0 is as bad.
its far more reliable and you know it.
the japs know the 2.0 is the best thats why they still sell it on home territory and didnt bother with the 2.5 hg failure thing

Might as well add in the Diesel engines as just read about Simons
Make this the ultimate poll for anyone who wants to prepare a case against
Subaru

:lol: +1 .... Should never have sold my PPP Wrx blob tbh! Love my Spec-D now its had the repair but I wrongly bought it for the Spec-D/Hawk look and frankly it would have been far cheaper toning down a 2.0 blob Sti into a sleeper (That doesn't scare my customer's when i arrive at their homes!). Still no point living in the past! Just got to enjoy it now :thumb:

on a serious not though poll needs to take into account how many blew when they were modded and running more power?? what mileage did they go at?? were they run on correct fuel??

to many factors, if you read scoobynet you will see that there are loads of newbs that fit all sorts off mods to engines without mapping and this will blow any impreza engine up eventually.

the poll needs to include standard engines only.

Nobody said the 2L isn't reliable but if we listened to you we would be led to believe they are and have always been problem free.
Trouble is the haters are very pedantic by only focusing on 2 issues with the engine and ignoring the rest of the car . The Hawk is a better car than the blob in many ways, apart from 2 known engine issues that have known proven fixes.:thumb:

so can you answer me this.

do you have a 2.5?
has it ever been rebuilt??
why was it rebuilt??

the hawk and widetrack blob sti are the same car apart from one has a 2.0 and one a 2.5.

apart from 2 known issues that the fix is to take out the engine and rebuild it, thats ok then as long as its not an expensive fix:freak3:

Exactly right. We have also seen in many threads owners admitting to using incorrect fuel as well.
When mine went pop is was modded. I only use 99ron fuel but cant vouch for the previous owner.

all engines have failures, but bad modding and maintenance will account for a lot of imprezas regardless of the 2.0 or 2.5.

also a car thats 13 years old and done 130.000 then the engine goes can hardly be regarded as a failure.

I think the post below answers your questons mate.
according to the subaru press release iirc when the Hawk was released they said the chassis was 125% stiffer than the previous model. I believe the hubs are also larger but will stand corrected. I'm sure there were many more improvements as car manufactures do tend to improve their product as new models are designed.

Agreed :thumb:

the widetrack blob and hawk both have same size hubs 114 pcd.
the chassis is the same.

its essentially the same car.

I didn't realise the widetrack was 114 pcd. I have however heard of a few blobs starting to rust quite badly under neath. Thats face it, the japs have never really been known for long lasting quality products have they :lol1: Fast and fun but built under the accountants supervision.

Ehh? Wrong thread on this one i think mate?

as said before its the same car, the rust issues were on early bugeyes it was a few of the bolt on parts not the shell so easily replaced anyway.

the newage cars are pretty good rust wise.

This actually in a way goes to prove a point. If you look at the Hatch / 2.5 failure thread it is many pages long and that indicates many blown cars. Or does it?? Take all the BS out of that thread and i wonder how many individual cars are declared in that thread? A lot less than the page count indicates :lol1:

No arguments there mate... these kinda threads always end in discussion. Kinda why I went the route of the poll with it but given that i can't edit it once live it seems to have proved a short lived idea (unless a mod reads this and happens to be able to help?!).

the 2.5 has known documented issues, much more than the 2.0

its a fact and everyone including im and subaru is well aware of it so i dont see the point of the poll at all.

anyone who has been around subarus for a while will tell you this.
you will always get people trying to tell you different, ironically its from a man with a 2.5 that had to be rebuit .

:hjtwofing:hjtwofing but as i said, mine was modded :thumb: The fact is the Bloke at Prodrive who built the RB320's which standard were 316bhp said the engine was 10% below its design brief. Mine damaged 2 pistons at 360bhp. Modded cars are far more prone to piston issues than standard and 06 sti's are more prone to HG issues than 07 onwards. It is far to say subaru did not build the 2.5 with modifications in mind but what manufacturer does these days ? The days of over engineering by manufactures is over and the cars that were are now getting tired. Either way the best route if you want to mod is have it over engineered yourself. I can't really blame Subaru for my pistons. They sold a car with 316bhp not 360bhp.

the newage 2.0 sti uk engine is fine up to 450 bhp....

But now at least 8 years old. My bet is most with the mileage they have done wouldn't safely take that power unless re-built.
