280E whistle/whirring noise when cold
Hi, after reading heaps here for the last few months, finally got the courage to post.
My 1981 280E (253,000 km) is immaculate - recently had valves shimmed, uses no oil to speak of - uses about 500ml of water every 500km.
The problem I have (or is it not a problem) is that when cold to 70 degrees Celcius there is a whistling whurring noise from the front of the motor.
Everything else with the vehicle is fine - is it a slipping belt? head gasket on the way? vaccuum problem?
I dont know! Hopefully someone can help!
