My murray riding lawnmower has completely locked up and i need to know where to add the oil and how to grease the locked up parts

If it is the engine that is locked up, it is better to look for a replacement engine instead of trying to rebuild that one.
Good day.

17hp water cooled twin v engine, what are the valve adjustments and whar are the steps in adjusting them

Hi valve clearence settings are .004 thou, You need to have the engine on top dead centre and then loosen the locking nuts and adjust accordingly whilst sliding a feelr gauge in between the top of the valve stem and the rocker arm. But dont forget to retighten the locking nut up afterwards.

If that's a Briggs & Stratton engine, try this:

Valve adjustment for 28 and 31 Series B&S OHV engines done with engine cold.

The best thing to do is buy an Overhaul Manuel for this series of engine,
between $15 - $20..

Remove the valve cover. Remove the spark plug and turn the engine to TDC
(Top Dead Center). Now some people will say that there are 2 TDCs on 4
stroke engines. While the piston does come to top twice per combustion
cycle, the TDC referred to in all 4 stroke overhaul manuals, whether auto or
lawnmower, is when piston is at the top after compression stroke. Turn the
engine in the normal direction of rotation, watch the rocker arm action to
determine when the Intake Valve, the bottom valve, has just closed, use a screw driver in spark
plug hole to feel when piston is coming up and then at top. (A better idea
is a long pencil with an eraser, put the eraser end in spark plug hole) Per B&S
instructions, continue turning engine until the piston has receded ¼" down
past TDC. To do this, put a mark on screw driver (or pencil) ¼" above highest point
reached to tell when piston has receded ¼". You will need a torques head
screw driver bit for the locking screw on tappets. I would check to see that the Rocker Arm Studs are still tight in the head, they sometimes work loose.

The proper setting is Intake Valve - .003 - .005", Exhaust Valve - .005 -
.007". Use a flat feeler gauge between the Rocker Arm face and the Valve
Stem. These settings are critical as the Intake setting controls the operation of the Compression Release. I usually have to make 2 - 3 attempts before I am satisfied with the setting. When you think you have the proper clearance, take a hold of the Rocker Arm and move it by hand, side to side, etc, as much as you can and recheck the clearance
setting. The nut must be held while Locking Screw is torqued to 60 inch
lbs. I recheck the clearance setting again here. I would re-torque the head bolts while you are there.

I recommend removing and reversing the Intake Valve Push Rod when adjusting
the valves. If you remove the Aluminum Intake Valve Push Rod, you will see a
worn area down a little ways from the Rocker Arm end. This is from riding on
a fiber support rub block and the aluminum push rod will eventually bend or
break. Both ends are the same and reversing will prolong the life of the
push rod.

Note: IF you remove the push rod or any other rocker arm components, there
is a cap that sits on top of each valve stem, take care that you do not
dislodge and lose the cap. It is between this cap and the rocker arm that
you actually take your clearance reading but you will not notice there is a
cap normally. (Apparently, from the Overhaul Manual, ALL engines do not have
this cap)

Replace valve cover with new gasket, torque valve cover to 60 inch lbs.,
replace spark plug.
