I have just had the cylinder head gasket replaced on my wifes 1993 2ltr 190E at 105000miles ,I decided to have a new Mercedes OE duplex timing chain kit fitted while the job was being done, after completion of the job there is a whine form the timing chain area, not excessive but noticable enough to hear when driving the car, spoiling what was a really quiet engine, I told the motor engineer who did the job that it sounded as if the chain was too tight, he agreed that it was the timing chain making the noise and said the chain tension was controled by the oil pressure which was heathyly high, so could not be adjusted, and asked me if I would run the car for 400 miles to let the chain run in, he said he was 90 percent sure it would quieten down, but if it was no better or got worse, he would strip it down to try and find the problem, can anybody tell me if this is normal, I dont want to risk engine damage
Thanks
