Head bolts
3L of coolant
Rocker cover gasket
Front cover seal
Timing chain tensioner seals
Inlet manifold gaskets
(depending on if head work is done)
Exhaust manifold gaskets
I think that is it.

there was a merc bulletin reducing the oil level for all 104 engines - do not fill more than halfway between min and max on dipstick.
will likely cure your problem.
please report back on results.

I've also been told it is most likely the timing cover thats leaking and not the head gasket, but it's hard to tell untill it's apart and when it is, it's not much more work just to change the head gasket anyway. 
Do you think it would be possible to change the head gasket without having the head skimmed? As it has never over heated and the coolant and oil haven't mixed and this would make the job much cheaper and easier for me to get done.

This is debatable. Personally I always send the head off for a pressure test and clean. I also ask them to check the head for being straight and true. Total cost............£36. To me it makes sense to send it away.

Make sure you get the right headgasket. You need an AMG one and not the 320 one.
Do you always change the bolts? I measured mine and they were well with spec so I re-used them.

£36 is a good price, but it's mainly the amount of time the car will be off the road that's the problem for me at the moment. I'll have to ring around and see if I can find somewhere I can get the head to them and back on the same day. Unless I book some time off work to get it done.

Always. For the cost of them I always replace them.

when was that - 1910 ?
Do not underestimate the time to do a gasket change on the twin cam 104 6 cylinder engine engine.

skim and gasket change for £115. He must work for peanuts as its an 8 hour job. A Mercedes gasket alone is going to cost in the region of £50.jeremy 2516

I got it done about 6 months ago . Admittedly I got it at wholesale but still .
You guys must be used to stealership prices . The skim and presure test cost £80 and the Steel(?) HG £35 .
I think the price is still valid including pressure test .
I can get you the details on Monday if you like ?
Middlesex Rebore in Mill Hill are a similar price too . Valve lap-in and seats are about £2 ea there .
You do realise that I took the head to them don't you ?
My garage took the head off in about 20 minutes , and re-fitting took about 2 hours .The price for that was included in the engine fitting .
BTW never change the head gasket without checking the cylinder head . Once the head is off you must get it done .
