High pitch sound after starting up from 1yr of non-driving

[DrifterRZero]

Hi, every one. I need help with a engine sound problem. My vehicle is a 1991 MR2 turbo. For about a 1 year, my car has been sitting in my garage after I replace the motor with another 3S-GTE (I drove briefly and the engine seem fine before I park it for a year)(I occasional start the engine up for the first three months to idle the engine and then the rest of the years left untouched) .

Here's the problem, I decide to start up the engine (getting close to start driving my MR2 about four months from now). For 8 minutes the engine run normal and then a high pitch sound started to come from the engine area (about 3-4 sec of high pitch sound before I shut the engine down). I let the engine rest for about a minute and restarted the engine and the high pitch sound come on ( 3 sec of hearing it, and then shutting the engine down)

The oil in the car was new after I park the car. RPM Idle normal, no unusual engine vibration before and after shutting the engine down.

Could the problem be a loose belt? or not enough oil somewhere in the engine ( I though I idle the engine long enough to oil the engine)?

Any information will help me, All I want to do is drive my car again, I getting tired of driving my family 4 DR Corralla.

Damn, sorry about double posting threads. How do I delete a thread?

It sounds like your accessory belt slipping, try tightening your tensioner which is located low on the passenger side of the engine bay. You can also spray some belt conditioner on the belt in addition to tightening it. Good Luck!

If you have AC, there is a 2nd belt and a tensioner for that one as well.
