Should I pop the valve cover?

One thing I haven't done is pop off the vavle cover to inspect underneath. The reason I haven't is because I have no idea what I'd be looking at. But I was reading something that said if a tractor has been sitting a while, you should pour oil over the rockers or something like that.
Should I pull the cover before I try to start it? If so, what should I inspect for while I'm under there? What should I do to prep the area before starting the tractor which hasn't run in 10 years?

Bob, what kind of lube should I be squirting?
The fire up day shouldn't be far off. I have a gasket coming for my oil pan. I want to knock out the dents as soon as the paint and body folks tell me how. I need to buy hoses as you may have read... and that's about it, other than the work I need to find the time to do to get it to the point of firing up.
One more question, for anyone, do I have to remove that structural rod that connects the instrument panel to the radiator in order to get the cover off? Looks like I will, but I thought I would ask first.

If it is real dry in there squirt something like penetrating oil to let it soak down the stem to inside the head. Otherwise just use engine oil. I had to remove that rod to get the cover off mine. I took it off at the rad and then took the nut off the adjustment sideand slid it out. I was able to get the cover off without taking the steering rod out. It was tricky if I remember right but wiggle it the right way and off it comes.

If you decide to pull the valve cover off, take the nuts loose and let it sit a few days, then gently bump the valve cover sideways slightly and slowly start to raise it up. Look closely that the gasket doesn"t stick to the head in one place and to the cover in another. Unless someone "blue glued" it or used some kind of sealant you might be able to reuse the gasket for a while. If it cracks though it is done for good. Be ready to see all kinds of crud in there, but if you don"t disturb it it will stay put or if you clean it up in there , plug any holes that will let the crud find its way to the oil pan like around the pushrods or any oil drain back holes. The valve cover inside can be cleaned since it will be off anyway. Like the others have said it can"t hurt to spray or squirt some lube on the valve stems in side the springs and on the notched part of the rocker arms. It is ok to let some oil go down the pushrods holes also as some will find its way to the cam. How close is the "big fire it up day"?

I think you should remove the valve cover and check to make sure that none of the valves are stuck and make sure that the push rods are straight. It would also be a good idea to check the valve clearance settings. Make sure everything is clean and put lots of oil on all the parts. Make sure you put in a new gasket too.

Does it require a gasket to get put back on if I pull it?

More than likely. Gasket is probably cork and they do not like to be disturbed.

I think it would be a very good idea to at least have a look. Sometimes a valve or two will stick from just sitting. A stuck valve can result in a bent pushrod. Pull that cover, turn the engine over slowly by hand, and watch for ALL of those rockers to move an equal amount. Make sure that the valves also are ALL moving up and down an equal amount. An ounce of prevention is worth a pound of cure.

Super easy and confidence building info!!!
Buy a pump type oil can that has a plunger inside and a thumb lever.(like the tinman had, not the kind that has a push in bottom)
Use a small piece of small diameter rubber hose as follows: Remove the oil pressure line from the engine block. Use the rubber hose as an adapter to the oilcan spout (use a hose clamp if needed on the spout, but probably not)
Fill the can with engine oil and pump a couple of cans of oil into the engine's oil gallery. At some point there will be a noticeable vhange in the pumping pressure. This indicates it is filled with fresh oil (including the valve train pretty likely).
Put the pressure gauge back in the block, and fire it up. Best of luck, I agree with Howard, get it running. JimN

I wouldn't get too excited about it. The rockers don't move fast enough that they will hurt themselves before the oil pressure come up. Yeah it's probably pretty gunky under there but if the engine starts and runs I'd leave it alone. On the other hand you could be tearing down the engine in the future anyway. I'd concentrate on getting it running first. If you keep tearing it apart you soon will have nothing but a bunch of parts to sell. That's my take Mike. Not to be mean or anything but I know I used to do stuff like that myself. I was way better at taking stuff apart than I was getting it running. Whoa, listen to myself! Have I have come full circle and back to doing the same thing? Must be my 2nd childhood.

I would pour 2 or 3 oz of engine into each sparkplug hole then just crank the engine for about 15 or 20 seconds to coat the cylinders. Keep an eye on your oil pressure gauge to see if you have pressure when cranking. If you have pressure I would reinstall the plugs and see if it will start. Hal
