Oh, well it was some time ago now but can remember as a apprentice doing a timing belt on one of the said cars after it had snapped and no damage had been done, I have slept since then though.

i could be wrong..............either way it was a stonking engine that you could spank all day and it would still start the next day
nothing vauxhall have made since has come close to the good old xe

My mate had an 86/87 Cav SRI (1.8 8v) hatch, and his belt snapped - albeit at slow speed/minimal revs, IIRC. Got away with it - no intimate meeting of valves and pistons.

The diesel engines that failed were 2.0L and diesel engine failures totally different reason to the 2.5L petrol.

Spot on

Early 8valves have pockets on the pistons, the valvers didn't. If a valver belt let's go then valves will catch, and as Shreksta says they are a pretty solid lump that takes a good hammering with mega miles on them sure it weren't an ecowrek engine

Not what I heard :P

That'll be the reason then. A non-interference engine

iTrader: (1)

Yes I agree
Different engines and different reasons

But

All have same faulty components and

Not fit for the purpose of long life

Any judge would rule in a court of law a reasonable life span
Certantly over five years
Not 19k miles or less

Subaru was (and should be ) a premium product
Not just a 5k budget hatch

Yes, but before this, one must admit there is a problem in the first place.
Subaru UK have made it quite clear that there is not a problem with the 2.5 STI.

urban

iTrader: (1)

Absolutely.
In fact a friend of mine had a 2008 STI go rattle rattle rattle.
No oil blah blah blah, he was told that he had driven the car to destruction, and warranty denied.

urban

iTrader: (1)

Yeah, this was posted perhaps as a direct result of the post on 2008-2010 engine failures.

Chris for last 2 years I has complained about two issues

1) ProR 340 performance pack not working correctly
2) erratic/sporadic oil usage 400 miles none or 400 and 0.5ltr

The ProR 340 pack issue was resolved October 2013 so nearly 2 years
The Oil issues was looked at 4 times and did Subaru tests and dealer compression and drop down test. But at no point did tests were not enough to warrant an engine strip down.

My point is that someone who had their warranty rejected every one would say "no way" "bs" as it could never happen like that.

I had mine done and repaired under warranty. So no sour grapes. It happened that way. I have no longer have any warranty as 3 yrs now up.

I paid crossroads to strip and remove pistons from new engine and replace with forge ones.

Yes not the most reliable method. Light on = to late.

At 4krpm yes understand oil light could still off But would expect to see EML with fault codes relating to low Oil Pressure come up.

But what's odd how it started up after 20mins being sat there and still put the light out.



Bob

No pistons were cracked or ring land damaged as far as I could see.

One piston bottom ring was broken clean in two and crack was old. I assume wasn't broken during strip down. IMHO

Tony

Great news getting it back. I hadn't seen the red devil around.

Surely the 24month of not running correctly has played its part in the engines failure?

Rob

So what now tony, you gonna keep it or you starting to look? If so what at?

salsa-king

if he's had it sorted and also had it re stripped with Forged Pistons all is good to go and no problems should show up now

STI7PPP

I spoke to him today. Car just finished running and 1K service. Said forged pistons was for his own peace of mind. C



Although hinted that be maybe one will have to go

I didn't think that there is / was a rev limiter on a standard car map?. Certainly never managed to hit it myself. you know how l drive........

Looked at new STi but £11.5k to trade up so doubtful.

Originally getting shot of MY11 and keeping the MY05 type 25 to do Trackdays but too busy now.

More likely to sell the type 25 and keep the saloon as weekend toy. Should last a bit longer that 19k miles now

How's things long time no see. Rally day?

I think it has a fuel cut system rather than an ignition cut

Hi Bob,

I fully agree in part

whilst the engine is rotating at 2.5-6krpm and loses Oil volume. I like most other performance peeps, agree and understand that enough pressure can be present to "maintain" the Oil Pressure light "off". And by the time light is on the engine will be FUBAR'd.

Tony explained to me is that and tend to agree with him by always learning and a high pressure high volume positive displacement gear pump.

1/2hr after engine was FUBAR'd and cold he started it up twice to test Oil light. he started it up for 5-10 secs each time. with NO or minute Oil in engine
, on tick over and it put the Oil light out. It was filled back up to mark with 4.2ltrs off Oil.

so with very little oil in sump how did it permanently switch Oil light off? I'd expected to see "slugs" or peeks and troughs on a gauge. Is there a high "debounce" timer in the ECU to stop "false" oil light issues?

Rob

If one "fully agrees in part", then one is neither 'fully' or 'partly' agreeing. Ergo, a paradoxical statement.

Instead, "I agree in part" or "I agree... But with some caveats..." would be far more appropriate.

Erm, is the oil light actually initiated by the ECU?...on older Subaru traditionally its just a pressure switch wired directly to the light.

I know VAG's have had more clever switches for years (even T2 transporters ) and the light is turned on by the ECU or the instrument control unit (to be precise), but even BMWs are just a on/off state switch; ergo they do not measure pressure, they just measure the switching threshold to indicate a presence of pressure (a few psi), but not how much.

Bear in mind you can pressurise air as all modes of measurement they are measured in relation to the amount above ambient air pressure (which is considered as zero, when its actually about 14.7psi) . So air within oil can be seen as oil pressure (the same issues apply to aerated fuel systems, which causes lean running issues).

He's a Factory Engineer and not "worked" on cars. He'd have a debounce timer on Bath Tap to stop phantom drips. LOL

He into Fluid motion and more used to pumping Fluids, powder and solids. Run by PLC's with PID's and monitoring amperage to assess Cavitation. I Helped him set up Vibration monitoring part of program.

So I assume the question should be " Is the light switch direct to the lamp as most cars or is it indirect through ECU.? Doubtful as it's digital and not an Analogue signal.

My MY11 has now done 70k with no problems. Only ever had V-power in it and has been serviced to the book. On scoobyclinic rollers it was bang on 320bhp at 5000 miles. It's just started to burn a litre of oil in the last 10000 miles. Looking to change it in next few months as 4 years old in October.
The wife has a M135i and that engine blows the Subaru to pieces. The torque is stunning giving instant response off the mark.

Hey Tony, apologies for the late reply. I am sort of retired these days and do as little as I can get away with and no more than I have to at APi
[ NO CHANGE THERE THEN ] before someone else says it .

I've seen your cars around at Crossroads and TDR, i was never at either when you've been there.

Seriously, Two of my Staff now own APi, my business since 1982, so a wrench really. Simon and Rob are two of the best folks I have ever had work with me over the years and they have a feel for Subaru much the same as l do.

Today is my start day and l'll be gone at lunchtime Friday, I amuse myself by doing the collections and returns and running around for the guys.

So l'm not far away.

Cheers David

LOL keep it clean

Going back on topic. It's a shame that the oil pressure switch isn't analogue back to ECU. They could them have different triggering pressure at different RPM and engine temps.

As the existing one is as much use as an ashtray on a motorbike.
