Yes - same engine.

JDM's price hike then

The oil pressure warning light switch has a setting of 0.15 bar !! its there to tell you the engine is rotating but not much else !!

The one thing thats almost certain to crack a piston is hitting the rev limiter, just once will do it.

Would lowering the rev limiter help in that case then or is due to the nature of the event it happens (regardless of the revs the rev limiter is set to)?

Is that for definite, 100% certain.

If so that thread where several users were calling people for even suggesting it might be the same engine needs a revival with a few apologies!

Have read this before, it seems that Subaru were unable to adapt to new European legislation as well as.....well most others, it's a shame really.

tarquin crispin

Me

Standard rb320 let go less than 36k on the clock, head gasket failure and cracked ringland(s) when stripped for rebuild.

No mods, now it has

tarquin crispin

surely you would of had a case when subaru have stated this

From the information gathered through Fuji Heavy Industries' Engineering Teams, our Regional Service Managers and warranty information, it has been determined that engine failures have occurred due to one, or a combination of the following points:

Engine rev limits being constantly exceeded due to over speeding
Vehicles being un-officially modified outside the design brief of the engine (unit is designed for around 300 BHP or 330 BHP in the case of the STI 330S, not more)
Track use (racing, time trials, rallying etc)
Incorrect maintenance procedures, causing engines to be run with insufficient or contaminated lubricating oils
Use of incorrect fuel grade (RON)
Unofficial "grey" Imports of undetermined specification, ie. not supplied by Subaru (UK)

There's plenty of stock vehicles in that thread. They just seem invisible to the naysayers!

The Subaru team of Engineers, who we believe to be the most capable and knowledgeable in the business have designed the 2.5 litre unit with lighter weight and lower friction materials, giving higher power without sacrificing current emission and CO2 outputs

my brother had a similar issue with the cavalier GSI many years ago he drove it 2 miles and the engine blew we got a mechanical engineers report done on the car they ended up replace it with a new engine

Carnut

Oh I know there's problems, it just makes me nervous agreeing with anything you say, you being a **** and all.

So any claim on warranty can be pretty much passed off with any of the excuses above from Subaru UK. What a joke, reason why I wouldn't have a new Subaru!!!

tarquin crispin

has anyone done a poll to see how many standard 2.5 have had engine probs and with what mileage would be very interesting

Carnut

I would give up now, I still get **** now because I asked the questions that you are asking.

There was, is clearly a problem with the 2.5 engine, by how much of a problem is anyone's guess.

Littleted

I think as this is Tonys and he was one of the first to get one like don and me, this will send waves now, as we all know he looks after them

Ticking time bomb... Get shut.... So glad I managed 30k in mine then sold,it, phew

tarquin crispin

have any of the cosworth 400's gone or did they put better items in ??

joz8968

Was explained in that report.

But as for failures.........?

Littleted

They had forged pistons and other enhancements yes...

Carnut

The thing is with that is what ever was done was by cosworth so not subaru's workmanship anymore, well maybe a bit subaru but you get the point.

thats hard to believe as the c20xe (redtop) lump is known for being tuff as old boots and more than capable of clocking up mega high miles aswell as taking a staggering amount of abuse

i have had retop's before and one was over 200k on original engine

the only real concern was the porous head problem on the non cos-cast cars this affected the cavalier/calibra and i think the astra gte/gsi

Carnut

Now going off topic but if not mistaken with this engine I am sure the timing belt can snap and all will be well, just need to re time and a new belt and off you go, no bent valves.

the shreksta

iTrader: (20)

nope i think thats incorrect,i think the 2.0 8v engine (c20ne) found in the cavalier sri 8v/calibra 8v is the one you mean

the c20seh 8v is not valve safe either
