does changing the oil/oil filter this way
1) Warm engine
2) Drain old oil from sump
3) Remove old filter
4) Pre-fill new filter with fresh oil. Fill and keep filling until it won't take anymore.
5) Apply new filter
6) Apply new washer to sump plug and tighten
7) Fill engine oil filler to mid-way between two holes on the dipstick
8) Disconnect crank sensor
9) Dry crank engine at least until oil pressure light extinguishes -
ideally for 20 seconds or so more.
10) Refit crank sensor plug
11) Check sump plug and filter seal for adequate tightness/leaks
12) Go for slow drive until engine fully warmed
13) Top engine oil to upper hole
14) Check sump plug and filter seal for adequate tightness/leaks

make any differance to the runing of the car or is this a load of sh*t or does it make sense to do it this way
thanks for your advice on this matter

 

Thats the way that I have always done it.

 

Seems rather nasty to dry crank an engine!
Remove items 8-10...

 

Can worms open...........


To clarify an engine in this state will never be totally dry,unless yoy=u decide to go on holiday after removing the oil filter ..... pickup will be covered in fresh oil,there will be remnants of the old oil covering the moving parts as not all will be removed in the draining process..... there are other issues involved but id do it this way on a flat four.... and i do and insist my dealer does it to,though they were not originally going to do it.... so who is right?

 

Cue a picture of the annual **** oil change meeting...

Despite any comments:
That is the exact way I do mine and have done for 5 years.

The cranking of the engine with sensor off is not a 'dry' cranking at all, but cranking the engine over without firing. This gets oil down all the galleries as it normally would be.

Keep to the routine.

quick question, surely draining the oil and filter change ,refill with oil etc blah blah ,is that not just like starting it the next day when you go to work? .or does the crank sensor come out for that as well?

 

Each to their own!

IMHO its just another engine. I change the oil in the Subaru the exact same way I have changed the oil in my past 9 vehicles. And guess what? I turn the key and it starts.

1. Drain oil
2. Engine flush
3. Change filter and washer
4. Fill with new oil
5. Have a cup of tea
6. Go for a drive

 

I've always done it the same '****' way with no problems. Can't see what the big fuss is about disconnecting the crank sensor for a minute.

 

Either way to change oil..... but engine flush i deff dont use.

 

How do scoobyclinic e.t.c. do it? Which ever way is ok for them is ok for me.

Not quite the same! When you remove the filter, oil that is held in the gallery above the filter will be drained. That oil will not be replenished until the gallery is pressurized with a fresh supply. Having said that, the boundary layer of oil held in the bearings should cope until pressure builds so disconnecting the crank sensor is a matter for discussion! Certainly pre-fill the filter, however.
As a matter of interest, the handbook makes no mention of pre-filling the filter when replacing!

i agree with dan,on the ramp,drain oil,charge the filter,sump plug back in,turn engine over,watch oil light to make sure it go's out,job done in 15mins!!

 

I was told to NEVER use flush oil.
