was driving the impreza last night gave it a little bit of boostingss and came back onto the normal road slowed down to cool it down and thier is a distinctive knock in the engine appears at about 2.5-4.5k revs, when i lift off the throttle thier is a fast knock as the engine is on the down rev, i know its hard for anyone to put thier fingure on it but im thinking the worst with an engine rebuild.

i just recieved my gems ecu yesterday ready for fitment aswell absolutly gutted

its a W reg 2000 model v5/6 running 312bhp

also i might add the oil light started flickering on as i brake slowing low oil would this make a differnce, obviously didnt drive it long at all with oil light on.

any help would be much appricated

thanks

davefaedeen

sounds to me as if your oil pump has gone as it did in mine!! full bottom end rebuild for me !! arrrggghhh!!

alex_impreza

£2000

By the time the oil light comes on the damage is usually done!

As above im afraid all the oil light does is tell you its too late,your probably losing oil pressure now from the knackered crank shells

The Zohan

Sounds like the bottom end...If you are still ragging it around then you might want to look at a complete engine and turbo!

davefaedeen

i was around 3 k ish i went for a v8 bottom end with all new internals built by subaru!!

alex_impreza

im not still "ragging it around" i said i put it on boost once and it boosted fine


ill get it looked at the oil light only comes on not very often

if the oil light is on or has come on under braking then your your engine has had it, your best bet would be to speak to API as i believe they do a fixed price fix for bottom end failure.

alex_impreza

yeh oil light comes on when braking thats exactly it, okay ill speak to api

thanks

just as i was looking at bembos and tyres for the track and getting the ecu put it absolutly gutted

Alex, if the oil level was low then you can expect the worse case scenario - engine rebuild time
The oil warning light or Engine Fooked Light as its commonly known comes on at approx 5 psi oil pressure so by that time the damage is done.

would the oil light not just mean its running low on oil though thats what i thought sorry for being daft?

All the light is any good for is telling you all is ok on start up when it goes out ,if you see it after that its all bad news.Its not for the amount of oil in the car its for oil pressure.

Dude, it doesn't sound good. 300 odd bhp on a UK engine is close to the comfortable limit. I'd take it to a good garage if not a specialists. It does sound like a bottom end rebuild but obviously nobody knows until it's looked at.

Cira £2k plus for a standard rebuild and losts more if added goodies are included...

Just keep your eyes open for a newage sti bottom end in the for sale section mate.

alex_impreza

why wouldnt i buy a new engine for about 1000? just for the peace of mind of the rebuild being done ?

what if i bought that and put my perforamnce bits onto it then put the gems in and got it mapped would this not work and be a lot cheaper option ?

Do a search for SMR engines and the various names it goes under then think again about buying a used engine (unless you have it's provenance)....

Alex - assuming it is the bottom end - if your driving/running the car on or off boost you'll do a lot more damage and need more work, as i said possibly a complete new engine and turbo. The bearing shells may well break up and trvel round the engine in the oil f*cking everything they touch! or you could put a rod through the side of the engine then it is game over for the engine.

alex_impreza

well ive already said ive not ran it today, someone said how does it sound and i said i borrowed a car from work so not tryed it today i dont know anyone who can come down and diagnose it either

You could do that and it might be happy days ,but there is nothing stoppping that engine going bang,also. I have bought used engines in the past on other cars and touch wood ,they have been good as gold. But other people out there have not been so lucky. If you spend £700 - £1000 on a 2nd hand engine you may find it will be sold as seen, so if it plays up after a week you have no come back,wheras a rebuilt engine will have a guarantee & be rebuilt using new parts,so its up to you.
Personally, i am not a fan of rebuilt engines,if my engine goes bang ,then i dont see the point in spending 3k to have it rebuilt when i could go and buy an complete car(sti) for 2 -3k more ,but that is just my opinion

alex_impreza

IF i bought the same engine as what ive got aat the moment or even an STI engine the same model year will it go straight in with my modified bits litterally bolt in bolt out?

midnight

iTrader: (10)

If you bought another uk engine(99/00), then yes it would literally just bolt in and you could take your modded parts off and add to your new engine.(which is what i did off my 99uk to 2000 uk).If going for a sti engine you might well need the wiring loom as well as the ecu,as well as the gearbox to get the best out ofthe engine as it has the ability to rev higher ,is stronger & the gearbox has shorter ratios.
