GET OIL IN THERE ASAP
you don't want rod knock
can you see any oil on the underside of the car? as stated above it could be leaking out at higher pressure
does the car smoke at all when driving?
and i would suggest that you get a friend or mechanic to do your clutch for you... removal is easy for someone new to cars... but bleeding a clutch is not so easy and requires two ppl anyway
good luck with the car.. and keep up the maintenance
