My prefered option at the moment is a complete used engine, just need to know for sure whether the Sti engine will go in easily.

Worst case scenario is break it for bits but I don't think it will come to that !

If I buy an Evo will it not break as often ?

After a 'spirited' run tonight, it sounds like another bottom end has gone to meet its maker !

Back to square one it seems.

WTF! This can't be happening...... can it?!

(BTW, Evos have their own problems - just 'different' ).

That is pretty much what I said !

Sounded like a rattling heat shield and then quickly got louder, oil level was fine this time as well.

Not the oil pump from the first engine by the way (or the modine) !

I may be about to see if I can live up to the sentiments expressed in Kiplings poem 'If' !

With hindsight, the phrase 'famous last words' springs to mind.

This bottom end was the used one I fitted last year as a stop gap.

Hasn't used any oil but I guess the recent power hike was just too much for the poor old thing.



Could someone answer me a genuine question ?

How good are these engines at coping with prolonged 'autobahn' type speeds ?

I'm talking about indicated 120-150 for a few miles at a time, I seem to recall reading somewhere that they do not cope well ?

As I recall, the article mentioned something about the small surface area of the bearings in comparison to other cars and the likelyhood of overheating due to lack of lubrication ?

I don't know if any of this is correct or I may have imagined the whole thing !

My wifes endless patience is starting to wear thin, she said 'fix it and sell it !'

I have asked what she wants to replace it with and she replied ' Not another Subaru !'

It will still cost money to fix it, even on a budget, then someone else reaps the benefit.

If I fix it, sell it and buy something else, I will need to put in a big lump of money to get anything interesting (Evo 8 onwards)

Decisions, decisions !

they dont like being driven at top speeds thats my own opinion having read numerous topics on here i wont be buying a scoob or a evo next due to the constant worry that its goin to blow up mines 2001 with 85k on it going next year i had a rs cosworth had 2 engine builds both went **** up started third time then said **** it 5k lighter just sold it i know what im doin iff mine goes **** up wall enough said after what youve ploughed into it is it worth trying to fix when there not making much money running

Detting at high loads/WOT for prolonged periods, and/or incorrect octane and low fuel, is indeed the no.1 killer.

The flat-4's horizontally opposed pistons are more prone to detting than a conventional up-right in-line-4. The configuration is not conducive.

Running on 99 octane, with a map from one of the best in the business and good quality oil, would you still expect problems ?

I'm not being sarcastic I hasten to add !

its done a big end so its oilling related.

Seems a bit of a coincidence to go after you having the engine out and back in.

I presume it was primed with oil etc? with plugs out or in?

I'm not saying det is what's caused your failure, etc.

Just answering your question, in general, about the inherent weakness of Scoobs when running high rpm/WOT for long periods, etc.

Turned it over with the crank sensor disconnected until the oil light went out (25-30 seconds)

With the plugs in, I can't face trying to remove and replace them with the engine in the car !

I wonder if chucking it through the hairpins earlier in the evening led to oil starvation / surge ?

Baffled sump ?

Baffled f***ing owner more like !

pistons are no more prone to det than any other turbocharged car.

the bigends are a weak point and high oil temps whcih happen on high speed runs cause thinner oil on bigends, which then pick up and knock knock

Sure.

But a well known specialist categorically told me that the flat-4 layout also brings on det scenarios much easier than other engine configs. (?)

not once setup properly.

there is a lot more heat influences on the flat4 engine yes..

but imho the issue with high speed is the heat build up in the oil brought on by the turbo getting hot, not helped by the tmic getting less efficent air flow through it etc

Cool (not literally lol).

Yeah, thinning of oi/insufficient oil supply... inadequate pressure through the bearings... always a big end killer (obviously).

which is why it is annoying when you see an oil supplier on this forum recommending the oil it says in the manual because he can read, but has no experience of what these engines need and is recommending too thin oil imho, but given up arguing.
