new member,valve adjustment question

[bob66542]

i just bought a 75 230 sedan.4cyl a/t. it runs good, but has a lot of top end ticking,i suspect it hasnt had the valves adjusted in a long time. ive done valve adjustments before(mostly motorcycle)i have the owners man. so have the specs- dosent say hot or cold,so i guess it would be a cold adjustment. does any one have any advice for me? any pitfalls to watch out for? this is my first benz. thanks, bob
