Well here it goes:

I had an oil leak for some time now and it seemed to be only external leak as in most M104 engines but today something was different i get in car start it up and when going through mine "bulb" and "low windshield fluid" messeges i notice "low coolant level". I shut off the car and went to check and well my hopes of computer going mad had shattered and coolant only filled have of the reservoir:mad:. So i topped it and turned car back on and see what will happen and surely after few minutes white smoke and smell i decided to turn off the car knowing i am not going anywhere! :(

Maybe this was cause by cold weather we are having in canada -20 degrees Celsius (-4 Fahrenheit) and lack of driving since i am in school and use the car only 1-3 times a week, has taken its toll on already damaged haedgasket.

So what do you guys think i should do? My thoughts is of making this car my project car and fixing it myself during summer?

Isnt coolant corrosive and waiting till summer would it rust all my rings

I dont know :( i am really depressed i love this car.

if oil level is not going higher and not looking milky, and if coolant is not looking oily, than you have no internal leak so no big worries. first thing i would do is pressure test the coolant system to see if there are any leaks. also check around water pump to see if it's leaking from weep hole. also you could have had coolant on min. and when parked on angled driveway the sensor read it as low. for now i would just keep an eye on things and not worry much, if low coolant comes on again then have a mechanic do a pressure test, takes only few seconds.
unless you are seeing big oil puddles on the ground, i wouldn't worry about headgasket as long as oil level is correct.

You have I6 engine? Headgasket replacement on such animal is couple hr of labor.
At least that is what it took me last time I did it years ago. Fact that modern engines have more stuff mounted to it.

Hmmm. that was the last year for M104 in an e-class which had the revised/updated headgasket due to the routine gasket failures on the M103. Anyhow, if the motor has high mileage 200K miles+ i would simply swap the whole thing out with a replacement motor from Metric Motors. They specialise in only MBZ petrol and diesel overhauls. If you have relativelty low mileage, simply change the headgasket (valve job as well) and call it good. Not very difficult with the inline motors. be careful w/ camshaft positioning!

internal or external leaking? is your oil level rising while coolant level getting low? do you have milky looking oil? or is the headgasket leak just external and in that case you oil level will get low.

headgasket job on m104 is about 8 hours, and usually don't need to do valve job like in previous m103. i think book time is about 10 hours, so the cheapest mechanic will charge around $1k for both parts/labor, but most of them will charge around $1.5k or more. a lot of times leak is from timing cover, and properly resealing timing cover (1 hour job) will take care of the leak. but if you are definitely sure it's the headgasket internally leaking coolant to the engine than the headgasket needs to be changed asap, and probably the head will need to be machined.
you might be better off getting rid of the car if cash is low.

I think first you need to do a compression test to see what the compression is. then I would align the timing marks on the crank and cam. pull the head and with the cam removed with the head upside down , all the valves would now be seated.you will need to put the sparkplugs back in and tight. Now fill to the head surface where the valves are with water and let it sit for some hours or over night and see if the water leaks out. if they all hold water then I would have the head resurfaced and have new valve stem seals replaced. the stem seals get hard and dry out and suck in oil into the intake. (ALSO) when you crank the engine fuel will inject so pull the fuel fuse or relay or you can dicconnect the fuel line at the fuel distributor and put a hose on the fuel line and have the other end of fuel hose going into a gas can.( So be careful with the gas)

If you know how to do the job or have a friend who can help you then you dont need that many tools. And you will save maybe $1000???????
