Valve adjustment

[slugish]

Ok , Im almost certain my ticking is coming from my valves
When I put engine back together , I adjusted lash . then 1/2 turn (maybe a LITTLE MORE )& I was real careful in the position of the exhaust lifter when adjusting the intake valve so it would be at tdc . Ihad the intake off at that time & could see when the lifter was in the position that would mean I was at tdc.

So I know a lot of you adjust with motor running > How do you keep oil from splattering all over .

Since now I cant see what position the liftres are in , can I tell when Im at tdc by the rocker position .

Also I know about , taking plug out ,turning engine over till feel air push out , but I would feel better getting to zero lash etc. like I did before , but can I do this by looking at rocker position (ie just beginning to rise or just before it goes all the way down .

Sorry for the length of this
