odd knocking sound when taking off

[fatgtr]

hey guys
recently i have noticed that when ive been moving off from being stopped i release the clutch and hear a strange knocking kind of sound its kind of hard to explain the sound really. but its really annoying me.
any help would be much appreciated
p.s its a st182 celica

does it kinda of have a "bag of ball bearings" sound?

if so might wanna check your timing.

What kind of petrol you using? 91, 96 or 98?

or it some sort of another mechanical sound?

its not really like a bag of ball bearings lets say its kinda like a fart and burp kinda sound. i use 91 or 96 depending on the price. but most of the time im running 91

Might pay to try running it on decent octane fuel for a bit and see if it goes away.

my old car (not a toyota) had a similar sound but only when i wasnt accellerating or put the clutch in... turns out it was one of the engine mounts that had gone and the wheel bolts were coming undone rather rapidly...
just a thought
