Rattles

[CLK?]

Ive had my CLK just over 2 weeks now and its been lovely, but now its started putting up a fight.

Every time I start the car, it is extremely loud and rattles a lot, I cant really describe the noise it makes, it sounds like a very very old car starting up, very rattely and gassy. The car has done 122,000 Miles now, are the lifters hydraulic ? Thinking this could be the rattle ?

yeah it could well be the hydraulic lifters. try & oil & filter change as the first possibility
may also at that milage be timing chain (depending on service history)

The idler on the front of the engine can rattle when worn out and very common,, this is part of where the serpentine belt goes around. I do not think that the engine would start making a loud noise

Speaking of oil change, where on earth is the filter ? Under the black cover by the power steering fluid resevoir ? Also when I was going to change the oil I was also going to pour some product in that sorts out noisy lifters, I think its made by wynns.

I would not put any additive in there for now.

Its easy to hear if the noise is coming from the top or front of the engine

Oil and filter change done, does not sound any better ! On inspection of the engine, the air filter is full of oil, its soaked, whats going on there ? Thanks
