Looking to do a valve cover gaskit, is it very hard to do?

single cam or twin???? heads.
we cant guess the engine, there are 2, 3.2L engines.

Does is smell like oil burning ? Make sure it is full of oil and that it is not overdue for an oil change

if you do not have exsperiance or have the tools for it.
go to a garage.it will cost you double cause its an delicate,
job .that can go easly wrong.you have to drain all the water.remove,
all tubes -airfilter-carburator-valve cap.you need special tool to untighted the bolts from head gaskit in the wrigh order.get the head carrefully off.the head must be checked in the garage cleaned flattend.
put the new gaskit in the wright way back.then the head bolts must be tighten also in the right order and tension.put all parts back fill the cooling and get the air out the radiator.also the new has to rodate for atleast 500 km.there are some books or manuel how to do it.

Valve cover gaskets are pretty straight forward. Usually 4-8 bolts to removal on the valve cover and its off. Make sure peripheral things are removed.

no idea never seen one sorry . wouldnt have thought a 1980 vehicle had a egr valve ?

This can happen. Check your oil and see if it is over full and turning a tan color. If it is not then the moisture is some what normal. Moisture gets in everything, Heat and cold together causes this. But if you are constantly adding coolant then you probably have a blown intake gasket. You should probably purchase a manual to do this job. I would be typing for two hours to explain this job, and you would still have questions.

Buy a gasket kit for the upper end. Remove the valve cover intake and exhaust manifolds. Remove the head bolts. Remove head and clean up block from old gasket material. Take the head to a machinist and make sure that it is not warped. If it is warped either replace the head with a new one or have it machined true. Install new gasket and get torque specs with new head bolts and follow torque sequence using the correct torque specs. Clean exhaust, intake and valve cover of old gaskets. install new gaskets and torque according to specifications.

if you mean you are actually burning oil and see smoke out the tail pipe then yes... it is something bigger... you need a head job or ring job

if however, you mean that oil is getting inside where the spark plugs are located then no... this is fairly common with the neon and you need a VALVE COVER set which will include the gaskets for the area around the spark plugs

Lots of work. Best bet get a Chilton manusl covering that year from the library or Ebay. Real quick disconnect battery, drain coolant, remove intake manifold, remove any accessories on the side of the engine you're working on , like compressor. Remove valve cover, loosen all valve rockers, remove all 8 push rods, remove head bolts, pull head. Lots of smaller stuff I skipped. You will definately need the specs to reset valve/rocker, torque values. Gasket set, change oil because there will be water in it. Better have a friend who has tried this before too. Can be done but it's tough to do the first time.

The PCV valve is inserted in the valve cover (through a rubber grommet); your particular valve looks like this:

The blue part of the valve is in the valve cover, and there is a rubber vacuum hose connected to the other end...

I'm not quite sure on the exact location, but if you look around it shouldn't be too hard to spot.
