Sump removal

[RSF]

Hi,
My car has a few serious mile's on it and I am planning a oil change,so thinking of pulling the sump off to see if there is any foreign material in there and removing it all.
If there is any material in there,any suggestion's on what they would of come off?
Any particular colour to pacific part's metal's?
Looking on the net it seem's there is no sump gasket,is this correct?
Any pacific way I should take the sump off or removal and fastening of the Bolt's?

Planning on a log on a jack and slowly letting it off when bolt's are removed and reverse when re fitting,just need to know what to expect when removing,correct way of un tightening/tightening the bolt's and if there is a gasket.
Any help much appreciated.

Shiney bits are bad in the oil infact anything metallic is bad !

Just make sure when you undo it you dont strain any edges or you may have problems refitting it. You are correct there is no gasket to speak off its a liquid gasket and supposedly theres 4 bolts holding the sump on torque these upto 17NM. Don't forget a new O ring on the oil pickup if you remove it [pennies at volvo]

It is a liquid gasget!

Yes diagonal and side to side - do you have a haynes?

I would say that you really don't need to remove the sump! Just drain and re-fill with fresh oil. They do mega mileages!

I'd leave well alone , if the engine looks clean inside the oil filler cam area it will be ok .
If it is crusted with black sludge then just cleaning the sump wont be much good , the whole inside of the engine will be covered ..

Not black sludge but a few black bit's.
I have a leak coming from above the sump and have a feeling it is the sump at the seal, so thought I well as Just take it off and clean it out.

What made me think about it was the parts for volvo site have a magnetic oil sump plug tbh,If that could get bit's there is bound to be bit's in there and I don't want to use a magnetice sump plug for just incase it pull's to much crap and block's the plug in..

Oil don't look like it has been changed for a while.

Yes I have a Haynes,just thought it was weird that the 850 don't have a gasket.

The reason I asked for pacific colour's of foreign material is so, I could tell which part's the shaving's are from,you can do this in other engine's I've worked on and tell which part is getting shaven,same with gear box.

While on the sibject is the gear box suppose to be sealed?this is another suspect.
Thank's for all replies.

Leave the sump alone, unless you have a specific reason to take it off.

Get a magnetic sump plug as previously advised and do an oil change. Change the oil again a week after putting in the new plug, this will pick up any bits of crap floating about. You can also get a magnetic band and put this round your oil filter.

You wont find be bits of crap in there. You engine would likely be FUBAR if there were big bits of metal in there.

If you really insist on taking it off the liquid gasket you need is called Hylomar.

Is it possible to get aleak from there?
This is the hole reason I thought about removing it.
It was me who mentioned the magnetic sump plug but would this not get blocked on removal if it does pick up shavings?
I was also thinking put cheap oil in for a week to flush it and then put good stuff in.

While on the subjects of gaskets,does the gear box suppose to have liquid gaket too?
thanks.

I have a leak from above the sump and am living with it.
The magnetic plug wont be unremovable, metal sticks to it and you clean it off when you take it out.

I'm quite sure the gear box has a liquid gasket on it. I can definitely see some of this on mine.

the leak above the sump is most likely the oil feed pipe from the turbo, get the gasket and green o ring from pfvonline, they only pennies, they all leak from there is it is the old red o ring, because volvo made the rubber ring of the incorrect heat compound and it leaks. thats why they changed it to a green one, so people could distinguish the correct seal.

its a fiddly job, but thats where the problem will be, its also alot easier than changing the sump.

Yea,
Ive ordered them but my gear box has had no gasket seal,don't look like it ever had a gasket,when we changed the clutch,the box had no oil in,so it's a concern.

Don't know how long my turbo ruturn pipes seals have been gone,would this of caused any damage?
