Engine running valve adjustment

[4C FED]

I tried to adjust the valves with the engine off & I cannot for the life of me tell when it is on TDC for #1. I see no motion from the #1 valves. So this leads me to believe that the lifters leak down to fast. Some I can see when they're at full lift, other I can't see move at all.

If I'm doing this adjustment with the engine running, do I employ the 1 full turn clockwise after they stop clattering?

Yur watching the wrong valves.

FO:

165
432

to adjust cyl 1 watch 4, 6 watch 3, 5 watch 2, 4 watch 1, an so on.

When the exhaust valve on the cyl yur watching just closes and the intake just opens (overlap) adjust the corresponding cyl in the list.

If you haven't found out already, without rocker clips, you'll have a mess. The above way is easier.

Sorry, but without double checking I believe the adjustment is 1/2 turn but don't hold me to it.

As usual I was trying to do this with removing as little as possible. So here I am with my arm wedged between the big opening on the fan on the drivers side trying to turn the motor over with about 1/16 turn each time. I can't see over to the #4 cylinder while my python is stuck down there trying to crank the ratchet.
My arms & hands are so beat up today from the ratchet slipping off.

I made some tall splash shields from cardboard. No mess, first time for everything, for me.

Anyways, the manual says 1 full turn after zero lash.

If you warm up the engine (before taking the valve cover off) and use like a 6" pieice of cardboard as a shield, it won't make a mess. I did this way and I didn't drop any oil.

Yes I imagine that would work. Hazardous waste when yur done? :rotf: I just think that doing it on a motor that isn't running will give you a more accurate setting. To each his own, especially here in the SyTy community.:tup: My way takes 2 full crank turns -after- you get to #1. The factory way takes only one so there's that option as well.

I let mine warm up with the covers off & still no mess.
