Just replaced my head, head gasket, timing belt, water pump and all accompanying seals. When the car is running there is somewhat of a whining noise. It’s not noticeable at idle but when the car is revved a little you can hear it. I removed the accessory belts and the noise is still there. Anybody have any idea what it could be? I really hope it’s not the timing belt.

I installed my timing belt too tight one time and it made the engine sound like it had a supercharger. It is possible to stretch that belt one tooth too many. Also, the preferred sequence on the belt tensioner is to install leaving the lockdown bolt loose so that the spring is doing all the work, rotate engine twice, then tighten the tensioner down. Sometimes rotating the engine with a free floating tensioner gets forgotten.
You should get a stethoscope. Make it easy to find whiny parts.My son has the 1987 325e, 2 door, 5speed

I’ll have to try your method of tensioning it. I assume if my problem is fixed I should just get a new timing belt?
