nothing wrong with that other than it looks like the oil cap seal is
leaking, or your friend added oil and spilt some.

But I'm sure someone will say you need a headgasket.

It really sounds to me like your 'friend' beat the living daylights
out of your car. We're talking about something like racing it hard,
really hard, or doing deliberate to damage it.

I agree, the smell is probably the clutch. This can be caused by his
inability to drive a manual shift car. Or it could have been caused by
deliberate (or perhaps inadvertent) abuse.

As to the loss of oil and coolant: oil loss implies that the engine
was pushed to high RPMs perhaps, which can increase oil consumption
both temporarily (excessive oil past the rings) and sometimes
permanently (damaged valve seals).

Low coolant implies that perhaps the engine was also overheated.

I'd recommend that you (I'm sure you have already...) bring both up to
spec, and drive a few hundred miles (or KM). Recheck both frequently
until you see that either it is no longer using too much of either
(and you are really lucky) or that you can estimate how much yuo are
now loosing (not so lucky).

And as to that 'friend'...   With friends like that you don't need
enemies!!!

(And don't lend your car in the future!)

Three questions:

a) When the engine is dead-cold, and you release the coolant cap, do
you get a *POP*?
b) When you are done with a moderately long drive (that is, the engine
reached full operating temperature for at least 10 minutes), put the
car in the garage and allow to get cold as above (overnight). When you
remove the oil-fill cap, is there any grey/white/pale-brown foamy
sludge on the cap... about the consistency of warm vaseline?
c) What does your temperature gauge do? Does it cycle between hot and
cold rapidly?

If yes to the first, you have either a blown head-gasket or a cracked
head. Either way, some oil and coolant may be being blown out your
exhaust.

If yes to the second, you are getting coolant into your oil via some
mechanism which then reacts with the oil to form the sludge. This last
test must be done only after the engine has been run at full operating
temperature for sufficient time to clear all the natural condensate
from cold starting out of the oil. So do not be overly alarmed if you
see such sludge after a series of short trips with the engine cooling
between each one. "False Positives" are common.

Lastly, it could be that your thermostat is malfunctioning. If your
engine is running cold, fuel consumption will increase greatly. If the
stat is short-cycling, then excess pressure will build in the engine
loop, blow-off coolant and so forth. The engine will overheat a bit and
use excess oil, then cool suddenly when the stat does open. All of it
simply *not good*.

If "NO" to all of the above, then fill to nominal levels and keep a
real eye on it. Betcha your friend drove at very high speed at
something of a load. Oil consumption is logarithmic... the first bit
takes a long time to use, the second bit much less, and so forth as
less and less oil is in the sump to handle heat and wear.

But in a complete vacuum, from a distance, not seeing the car and given
its approximate age and condition... I lean to the T-Stat.
