Hi guys My friends E class has a lifter tick & he doesn't know what to do with the car. I told him to change his oil and try a flush kit...no luck any suggestions.

what year/model? what kind of oil is he using? is he sure it's the oil lifters ticking? tell him to add a can of bg44k to a half full gas tank, it will clean the fuel lines really good. i think advance auto parts sells bg44k for like $15-20. it;s a little expensive but works better than techron or the gas treatment that mb sells.
if that doesn't help than suck 1L oil out and add 1L of non-synthetic atf, i was suggested this procedure in order to quite lifters.

Is he using synthetic oil? If not, it is probably varnish buildup. Can you provide more information, year, model, oil used, etc?

Lifter tick is common, I can hear some in our E500 from the day we drove it out of the show room. But I agree, you must use MB spec oils in the engine to prevent issues. If it is running MB approved lubes I would just drive it out unless it is really hammering then back to the dealer to check for defective lifter/camshaft issues.

I don't use snake oils..

If it's and '05 it will still be under warranty unless he's past 50K miles. He should just take it to dealer.
