hi all

my mates got a subaru impreza turbo 2000 (uk spec) and we did an oil
change yesterday on her BUT after reading the threads on
the forums it advises to FILL THE NEW FILTER WITH OIL BEFORE REPLACING

I did NOT do this

I've told him not to drive it till i find out if it will mess up the engine

can someone PLEASE tell me it will be ok????

 

think it would be fine, it is prob best to fill 1st, but i bet alot of garages do not do it anyway

 

think it would be fine, it is prob best to fill 1st, but i bet alot of garages do not do it anyway, would be worth disconecting the crank sensor 1st and turn the engine over a couple of times, re conect it, wait 5 mins or so, re check oil, top up if needed and all should be good

 

it is 100% ok!!!! yes would'nt do any harm filling the filter but i hate guys going on about this pre filling oil filter/crank sencor myth.all it does is fuel the cabury engine brigade

 

thanks da1

i was going to say to him bring it round 2moz and i'll drain it and do it the correct way. i was wondering why it sat (vertical under the block)

so you think it should be ok? i used the exact amount of oil and made sure
all leaks were checked and showing max on the dipstick

 

thanks for the quick responce guys (i can sleep at night now)

i was really concerned that it might have harmed the engine.
would i still need to disconect the crank sensor? or will it be alright?.

 

get in and drive the car! its just been freshly serviced,you've nothing to worry about.
bad fuel and silly mod's kills boxer engines not oil changes

 

he-he bpm

thank god for such good people like yourself bpm.

may be i worry to much.

i've only joined the site tonight and will be coming back for sure.

thanks again

 

It's been proven that the engine is under more load when dry-cranking than if you just start it and run it normally at idle.

Priming the filter should be a definite though, as the brief period of oil starvation to the crank bearings as the new filter fills has been linked to some engine failures as the case hardening on the bearing surfaces degrades in the absence of lubrication. Brim it 2-3 times prior to fitting.

 

oh

now its been done without filling the filter do i need to still perform a drain again? or will it have already flowed into the filter think he s done around 50miles since the change.

what i mean is would it be to late now and would what damage could have happened already been done?

dam sorry for all the questions

 

Forget about the crank-sensor removal .... it does far more harm than good churning away on the starter!

Main Dealers don't bother filling the Oil Filter - I do, because I always have, but it's probably not needed at all .... it's the one **** moment I allow myself.

Sleep well, as long as the oil is FULL on the dipstick, start it up, run around the block, stop, let stand for 30 minutes, check oil and top-up .... job done!

 

No need to do the job again, it's done now. It will 99.9% certainly be fine, but for future reference it is recommended that you prime the filter. The oil pump will have filled the filter within a couple of seconds of you firing her up, but it's that couple of seconds of starvation where the damage can occur. If the filter is virtually full then the risk is negated.

 

again thanks for all the advice i should have looked into it before i even set about touching it.

a lesson learnt for next time

 

as what c/boy put above. the best thing to do, if it happens again, is to fire up the engine and let it tick over for a good 5-10 mins. this should ensure the filter is filled up via the pump.

personally i fill the filter first, but i have changed many a filetr, where it is near on impossible to pre fill it, and you just have to put it on dry... make sure you smear the o ring on top of the filter with a little new oil too, this ensures it seals correctly and doesnt stick, once you come to remove the filter again.

 

Am I right in saying this is all a bit walking on eggshells.

I thought that when you do an oil change without topping up the filter all that happens is the filter fills up as you put the oil in the top?!?!?!

I may be being a dunce here but I'm pretty sure that if you were to remove the filter prior to draining the sump you would get oil all over the shop?!? so that would mean the oil must me in the filter from the filling?!?

 

that actually makes complete sense corradoboy and has put my mind at rest.

 

well,my oil filter is located behind the headlight and it cannot be filled before fitting, it fits screwside down, never had a problem.

 

Due to air-locking you cannot guarantee that the filter will fill, so spend a minute or two doing it prior to fitting. Once the engine starts and the oil pump pressurizes the system it will quickly redistribute the fresh oil, but if the filter is empty there will be an interruption in the flow for about 1/2 a litre which is where the trouble has sometimes occurred. It is well reported that Scooby engines often self-destruct within 200 miles of a service, and this has been identified as the probable cause.

 

mate there's two schools of thought on here,its up to you who to belive or trust.but i have had 3 scoobs over 10 years or so and i have'nt blown up one yet.they are jap saloon's not high tek f1 cars.
the basic boxer engine block design fitted in your car right back too early legacy's has been knocking about for near 20 years or so,must be hundreds of thousands of units produced,its not that special that it needs to be treated with kid gloves.
get in and drive the car and next time round load the filter to keep every one happy.im sure the mille second it takes for the oil to pass the filter won't cause any lasting damage to your engine this time round

 

PLEEEEEEEEEEEEEEEEEEEEEEESE

Fill it, start it, drive it ...................................... end of!

 

oh dear

i didnt want to start arguments.

 

Just to add (as it hasn't been mentioned) fill to half way (on the dip stick)... not full. Do a search......... pretty much every one of Mike Woods posts are related to oil/maff/blow through questions...

 

as ive already said, i CANT pre-fill my filter,no problems here.touches wood ha ha

 

Guys whilst on the subject what oil did you use my son is going to service my car but he was not sure what oil to use in a UK Turbo.
Cheers
Colin

 

10w 40 semi syn will be fine

 

On a lot of cars you cant pre fill, so that says to me that the manufacturers arent that bothered so why should anybody else be ?

I know of half million mile taxis that get an oil change almost every week with no pre filling, its the fact they get an oil change that keeps them going.

What makes Scoobs go pop is over driving them and over tuning them, the candle that burns twice as bright etc.

 

What he said!!!

 

wrong! they do because there was a bullitin issued a fair few years back now stating why they have to fill it and spookily it has nothing to do with oil starvation.

just start the car, the light will go out within a couple of secs and everything will be ok.

 

Really? You telling me Main Dealers Pre-Fill Oil Filters? ........ I'm not saying you are wrong - but, could you point us to the Bulletin in question? I will alert my Main Dealer to what they should be doing!

 

CB, can you clarify where/when this was proven..
