Evening chaps, just wondering if anyone could tell me what is causing my oil to look like this?

I first suspected a head gasket failure, as my coolant level is also dropping, the light comes on every 100 miles or so after a top up, although it doesn't look like the usual 'mayo associated with head gaskets. I haven't lost any performance, it still lights the wheels up in 2nd if it is a bit damp! Also the last oil change was about 1000 miles ago.
Any ideas?
Cheers, Phil
Points to headgasket I'd say, some oils mix differently and may not produce a white mayo gunk.
Bugger, not what i wanted to hear haha! well i'll see whats what in the next couple of weeks, if it is the head gasket it will be getting scrapped!
If it's just the HG then don't scrap it. There's less and less 306's on the road and they're good cars, they just need some TLC!
Well, im not sure what i will do to be honest, i am tempted to do the HG, if i do i will probably spend a bit more on it, do cambelt while im there, whip a bosch on and maybe even a td04, or i may just sell it as spares/repair. Not sure yet though!
Does kinda point to the headgasket, does it smoke white/grey?
Could be a blocked breather?
Hopefully will eithrr fix it or it can get fixed would be a shame to see it get scrapped
Thats either head gasket or the result of the car being driven a mile or two to the shops everyday of it's life.
Considering it's using so much water it's probably head gasket.
Just had a look over the car, the crap is only in the top of the cap, the oil in the sump looks fine, so could be the breather as mr.fish said, gonna whip the breather off and blast it out with the compressor and see what that does. There are no other things that point to the HG, no pressure in top hoses, no oil in coolant, no power loss!
Cheers for all the help guys!
I'd clean it out best you can blow breathers out keep driving it, if it Dosent come back happy days if it does probably headgasket
I was coming here expecting to see someone had had an actual crap in your oil... #devo
I have the exact same problem and symptoms
No pressure it top hose, no mayo on radiator cap or in the bottle, oil comes out sump just black as expected,
I left my intake pipes off when i replaced my blown turbo a few weeks ago and the breather pipe is full of that stuff, iv put the hose into a bottle to catch the crap coming out
Water and oil are definitely mixing somewhere as when i clean the tube out it is very wet and water sits on top of the grey stuff in places it can
Yeah mine had a bit of water sat on top before, not coolant, just plain water, will have a look at weekend when i have some new clips for the breather!
Have you got an oil-water heat exchanger fitted (between the oil filter and block)?
These can fail and allow oil and water to mix, giving mayo problems but no other HG failure symptoms.
I don't think so, i will have a look after i have finished work, cheers!
Maybe there is a crack in the head or something??
Those breather pipes connect the head and the block, it looks like it's catching the water vapour there and preventing it getting any further into the sump.
Maybe do like LolBen and fit a catchcan to trap the water.
Doesn't that breather come off the oil cap and into the inlet?
Yeah the oil filler has a pipe connecting the head to it and a pipe connecting it to the intake before the turbo. I noticed when replacing my turbo that the rubber than connects the plastic pipes to the turbo itself had split almost completely in two, could that have had an effect which could lead to this as there's no suction to pull heat through the filler?
