I was reading Haynes manual to do timing on my N Reg C180 Classic but i am a bit confused. Haynes manual says turn the crankshaft pulley to 20 ATDC to match the timing point on the timing cover. I am not experienced mechanic but i would like to learn. So i checked my car and i found some markings on crankshaft pulley but it if a bit confusing. Markings are something like this: ... 3|0 2|0 1|0 O|T 1|0 2|0 3|0 ... and rest of the markings on the pulley weren't clear.
I would like to ask where is the 20 ATDC on this markings. Could anyone give me very basic explanation because i have very small experience about the engine. The reason i am asking i try to change the exhaust camshaft and i messed up the timing so i know it is really dangerous game i am playing i can brake the valves or piston heads but i have to fix this if i can by myself because i could not found any reasonable mobile mercedes specialist to come and do the job car has no tax and insurance. Please give me some advise.
