Hi there,
3 years ago the car would make a clicking noise in the first 3-5 secs since start coming form the engine.Later that 5 secs the engine sounded OK.I was told by a couple of service MB dealers that it was something with the oils not going up intime and that it should not bother me.Note that if i step the throtle in the first seconds the clicking sound would go away before the 5 secs.
Before 6 months while climbing a hill with the car,i could hear something rattling.Happened only at about 1500-1700rpm while throtling.If i reved up more the rattling would go away.Because of the frequence sound,I thought it was the CATS touching each other as it had happened to me before with my SLK.I didnt paid attention waiting for the time i had to service my car to get the cats looked at,and today the car when it gets hot it makes the clickng - rattling sound when at idle , and when at 1500-1700 rpm.The sound gets worse when the car makes an effort to drive an uphill road.
The car eats oil about a liter every 10.000km and last time the dealer used 5w 30.I used two halfliters since the oil change one 5w 40 and one 10w 40.altough i think the second time the oil lamp light up and told me that it needs oil,i may have purred more oil than needed.It needed lets say half a kilo and i put in the whole one kilo bottle.Today 4.000km before service indicator i want to take it to my service dealer.Is it safe to drive it 300km to reach him?Local indys told me that the sound comes from the chosper ,a brake pump screwed on the enigne to the front left upper part of the V8 engine and it is gangerous to brake and then i would not have brakes.Other indy told me it is the timing chain and that if it brakes the engine would be totaled.but then again i read that no w163 has ever changed the timming chain.
What would you suggest?I would like to get to my dealer well informed.
thahk you.
Note that no engine light has showed up my dash.
ps:how much oil do my engine takes?I cannot find such an information the internet.
