So should there be oil floating around this system?
My commute is 10 miles per day sometimes I won;t use the car at the weekend at all.
Is there a away to keep this problem at bay without driving around aimlessly.

There will always be some oil mist - it’s the crankcase breather system. When it mixes with damp air, it’s forms mayonnaise.
A possible half way “solution” is run the crank breather into a catch can instead of the inlet pipe work - won’t stop the mayo forming but it won’t sit in the inlet pipe work.
The real solution is get it fully up to temp (not just heater hot) for about an hour which should sort it but with a 10 mile daily commute you’ll have this problem for about 6 months of the year. It also leads to short exhaust life too as that takes just as long to dry out.
Short runs don’t do cars any good - the gearbox oil is probably the same. Newer cars get up to temp a lot quicker so are more tolerant of a short commute.

Is it simply a case of pulling the pipe work apart and cleaning it, can it be flushed with something?

Generally yes, pull it part and clean it out. No need to get it spotless.

Thanks for all the advice. Very much appreciated.

Finding a 45 degree reducer elbow 15mm - 10mm seems to be an impossibility so I'm going to repair this instead.

I had similar things on one of the breather pipes on my Mk1 TT. You can get the pipe, but it's £40-odd for a pipe about 100mm long, because it's a weird shape. So I got some rubber sheet and repaired it. Still seems OK, for now at least. Make sure you get it properly clean if you want it to stick properly.

I'm going to try a puncture repair kit and then heat shrink over the top of the original tube. Fingers crossed.
I've found 3 hoses with holes in so no wonder the car was struggling. Once cleaned out it should be much better.

The saga continues This was the crank case breather. The tube was blocked solid.Spent a long time pushing solid bits of curse word out and then giving it a good clean.

I think some of the servicing was skipped earlier in its life. Cleaning breathers isn’t exactly a service activity but regular oil changes can keep this at bay.

It's bizarre, I change the oil every year. So maybe this is a problem that's been building for a while?
Hopefully put it back together this week if I get some time

The breather pipe on my old Audi coupe was like this. It was a solid pipe that came from the bottom of the crank case and up towards the top end, and it was full of stuff like this.

That's the one, solid pipe and it's a pain in the the clear once solidly stuff full of whatever the oily mayo mix is. This would possible explain all the oil thats leaking from the sump seal. Or it could me the seal is knackered too.

Hopefully put it back together this week if I get some time That looks like it’s been building up for years - unless you’ve owned if for 20 years then most of the blockage was there before you had it. From memory it was from the era where service intervals increased quicker than oil technology.

I've owed the car for 3 years, It's been fine up until I started making very short journeys. Now I know what can happen I can monitor it regularly.
It's such a relief to finally get to the bottom of the problem.
