Sounds like a dodgy build.
Phone David at APi for some advice. Personally (subject to what went wrong), I'd be considering getting a full refund from the garage concerned and taking it elsewhere!
All the best getting it sorted.

No refund, as it was my mate who did it has done a few scooby re-builds and ive known for 20 years and did it for cost price, as in no labour, i cant moan too much but its really pissed me AND him off(as he will be re-buildin it Again for free).i just want to know why and if its happened to anyone else or am i that unlucky?

Always always always change the oil pump after a bearing failure.
You must also renew the oil modine and throroughly clean the block by removing all the gallery plugs and comprehensively flush it out.
If you didn't change the oil pump then that would be your culprit.
Best bet is either an RCMS modified oil pump or the bigger 12mm AVCS pump.
Hope you fare better next time

In that case, I suggest either there was a oil priming issue when it was first started. A seal problem on the oil pump or pickup side to the pump allowing air to be sucked in. Or the builder messed up on tightening torques and checking clearances/tolerances, which probably caused a tight bearing to be wiped out due to insufficient clearances.
Unless the oil pump failed - contradictory to common thought on these boards, an upgraded pump doesn't automatically mean its better or more reliable than the factory item (thats why if fitting a new one, I'll always use a factory Subaru pump. I don't trust any of the aftermarket ones, no matter how "uprated" they claim to be. But thats my opinion based on my experience of the non-OEM parts industry though).
Either way, back to the engine builder for an explanation.

Unfortunately, this does illustrate why it's not always a good idea to let a mate do the work, or go with the cheapest quote. Even if the OP isn't getting stung for labour, he's still wasted a fair bit in parts that are now scrap.
To the OP: I really think at the very least your mate needs to get advice from a competent Subaru engine builder before having another crack at it -for the sake of your pocket and sanity!

1. S/hand "rebuilt" short engine wasn't as good as it was advertised.
2. First start-up to get oil circulating went wrong.
3. Underlying problem with car. Your last engine went in a similar fashion. Poor fuelling may have leaned out mixtures to cause detonation with bearing damage.
4. Driving style. High & prolonged speeds may lead to very high charge temps.
Pull the engine apart and post up pictures, but don't bother rebuilding again until the repeating failure cause is known.

The only pump that is classed as uprated i.e flows more oil is the 12mm AVCS pump.
Also the modifed pumps are just that they are modified OEM items.

I didn't say uprated I said modified. The pressure release valve in the standard pump has a grove in it and is prone to seizing. The modified one has this grove removed.

Was that comment at Ali really necessary, Daz? I very much doubt any of the mods would claim that their mod status elevates their knowledge of Subaru engines above non-mods!
Your valuable experience with building high power engines was all that was required in that reply! Please. lets not have the baiting, eh! You're better than that!

I would like to know what happened here as i seam to have low oil pressure on my engine that i just rebuilt. The only thing i did not replace was the oil pump so i have ordered a RCM one today.
