Engine oil everywhere.. What's the damage?

[Tomahawk]

I just lowsided going around a roundabout on a wet road.

It wasn't terribly high speed, only about 30 mph -- mainly due to leaning too much on a slippery road.

Anyway, besides the body damage, I seem to have lost a huge amount of engine oil as the bike was sitting there in a huge puddle of oil. What could have caused this? Does this indicate damage to the engine?

EDIT: I added pictures, see below..

Only if the engine was running after it lost its oil (possibly)
Do not run it until the leak has been found, fixed and oil renewed.
If you rode it home like that after the spill you've likely killed it.

You may have cracked or scuffed through a casing so give it a close examination

What bike? if its a 125 they often only hold about a litre so don't need to lose much to go critical.
A bigger engine may be more forgiving

Be fine just a cracked sidecase is all.

TAKE SOME FUCKING PICTURES

Have you not looked at the bike closely to figure out where the oil is coming from?

As Polarbear says, a photo would be incredibly useful. Especially if you want us to able to help you.

[Tomahawk]

So much caps lock rage here, lol.

Ok, I'll take some pictures tomorrow when it's light out. Just thought I'd ask in case it's a common thing that happens all the time when a bike goes down.

Thanks for your help guys.

[Tomahawk]

OK guys I took some pictures.

The damage looks like it's mostly to the frame, so I can't see why I should be losing so much engine oil.

There is a part that broke off (see 3rd picture)

[Pete.]

That scuff mark where the orange paint meets the black - behind there you'll find a cracked engine side casing.

Remove the fairing, take pictures.

Looks like it was a nice bike you have ruined

I assume the broken off piece is part of the engine casing that has ripped off as the bolt wore down. I guess the thread might need an insert. From your pics I cant see any exposed part of the engine case where a bolt could do this.

[Musketeer]

From the third photo is that actually a piece of your crank case? Because it very much looks like it.

If so then you're f00ked. It's going to be a major engine rebuild work to get it properly fixed.

Maybe a welding artist is needed

That looks like a fairing mount rather than casing.

[redeem ouzzer]

That's FUCKED.

[Old Git Racing]

Broken bit looks like it has a piece of gasket on it. Can't you at least take the side fairing off and take some close up pics of the right side of the engine where it appears to be damaged. The only way that much oil can come out is if the engine has a hole in it.
Don't try and start it.

OK, I took the fairing off and I found out where the broken off part came from.

There are a couple bits damaged in the slide, a bolt broken at the top and a chunk that came off at the bottom. (see first image)

There is a hole in the casing where the chunk came off -- see second image. Is that the engine casing or the clutch casing?

Everything else seems to be OK.

How bad is it? Can I just replace the casing and put it back together?

[Aff]

Thats pretty damn unlucky.

Pretty much a full engine rebuild to replace the bit that cover bolts onto.

A weld repair doesn't look very likely either.

You insured comp? Because that's a smashed crankcase and your engine is pretty much scrap.

Possibly could be fixed by a skilled aluminium welder but even then it's an engine out and full strip job

Like above. It's a major job to replace a crank case. Engone out and all engine internals need to go out. Not to mention a hell of work before you even touch the engine.. you need to disconnect/remove pretty much everything - drain the rest of the oil, drain the coolant, remove exhaust collector and end pipe, radiator, suspension linkages, rear shock, bolts that attach the engine to the frame, before that the seat, tank, air box and intake, injectors, throttle cables, wiring loom, all sorts of vacuum/overflow pipes. If you DIY then all you need is a room/garage, new crank case and gaskets and some bolts replacements and a lot of time.

To pay to someone to fix it will cost a lot. Many, many hours of work

Alternatives are:
- Some welding magician in your area (not likely)
- Whole engine replacement
