AMG

Car: 93 dx hatch
motor: JDM B18C

Problem:


Ok well i had made a few posts earlier about my car running rich and that the idle was fluctuating out of control. Well i took it into honda and after 3 ******* days i get it back. All they did was replace the IAC and hook up a few hoses. Now dont get me wrong, the car runs alot better, but i paid for labor on that!
Anyways, I just picked it up and started it up. The idle is almost fixed(still fluctuates, but barley noticable) and the richness has minimized too. BUT what I dont get at all was when i started the car up and opened the hood, i could hear a loud piercing noise comming from the timing belt side? It wasnt there before and we just replaced the timing belt when we did the swap (500 miles)!?! After letting it sit, the noise went away. I then proceded to drive it home from Honda. When i got to my house, I turned off the car and opened the hood. About 15 sec. later the noise came back, but this time when the car was OFF!?! I have heard a noise similar to this with my coolent lines but not by the timing belt! It sounded as if oil or something was trying to cool down. It was so loud that i had to back away and it went on for about 30 sec. What the **** could this be guys?

I dont understand what tehy could have done?

Please help
