This is the issue. I started to notice it about 4 days ago and I don't know what is causing it. My engine is sounding like it's a diesel when I accelerate.

I did an oil flush and change last night, but that didn't help it (it may have made it a bit worse actually). I also added some Lucas Oil Stabilizer (about 1/4 of a 1L bottle) but that hasn't seemed to help. If I accelerate very slowly, the sound doesn't occur, but other than that it does. I'm afraid of what this could be... any thoughts? Thanks.

Hole in your exhaust manifold or exhaust piping?

 

I'm pretty sure that's not it, it's definitely coming from the engine and doesn't sound like a hole in the exhaust.

 

Does it feel like you're running on 2 pistons?

 

Check your timing.

 

I'm not really sure what that would feel like. I'm assuming it would feel less powerful and acceleration would be slower. If this is so, then no. The car still feels like it's running the same, but now it has this noise.

 

Timing is definitely a possibility. I am in need of a belt change. I am at 144,000kms and it hasn't been changed yet. How exactly do I check if the timing is on or off?

 

check all of your spark plug wires on the plugs and the distributer, make sure they are all making good contact, i know it sounds easy but sometimes thats what it is. Ive had one come off before and it sounded just like that. best of luck

 

Checked all the caps on the spark plugs and distributer, all is good there. I've noticed that after about 10 minutes of driving, the sound gets quieter, but can still be heard lightly...

When did you got your last major tune up? I believe it's your Valve Adjustment.. It need to be adusted it you are hearing clicking sound or worst if it haven't got it done for a while when it suppose to be done.

 

Sounds like an exhaust leak from a loose flange or cracked pipe (maybe cracked manifold), when the exhaust heats, the metal expands and the leak gets smaller.
