Valve clearance adjustment

[Howard]

1985 250ES says " rotate the crankshaft clockwise and align the "T" mark in the rotor with the index mark. The piston must be TDC on compression stroke. "

is there anyways to confuse that? i mean if i line up the marks, that is TDC right?
Also, says to adjust the intake and exhaust to the same amoount "0.003 in" (0.8 mm).
do i adjust them both at the same time. i was thinking that it was adjust the intake at one point , then go 180 degree on the crank and then adjust exhaust.

i guess the question is, line up the marks, then adjust both valves to the measurment without moving the crankshaft between valves.

:thumbsup: im making it alot harder than it is i know!

If the rotor is on the T mark and the piston is at TDC you should be fine. The cam spins at half the speed of the crank. So if it wasnt on the compression stroke the T mark would be pointing down instead of up.

And when the piston is at TDC. Both valves are closed. So go ahead and adjust them both at the same time.

ok, Thanks :thumbsup:
