Need to repair valve cover gaskets. Need a complete parts breakdown

i know few
error codes/ fault codes, wiring diagrams, schematic diagrams, torque specs, engine fo, switches functioning, assemble, disassembly, complete refurbish, repair, installation every single thing is covered
within seconds u can get the access and it's totally illustrative complete

Pull off the valve cover, clean it like new, then use a silicone sealer on the valve cover only, place the new gasket on it and let it set-up (around 1 hour) then bolt the cover back on the head. If you are in a hurry, skip the sealer set-up time and just make sure that the gasket does not move out of position when you put the cover on the head. You can use the truck right after the repair.

You need to replace the spark plug tube seals in the valve cover. Very easy once you get the valve cover off. Make sure you get the valve cover gasket kit that includes the tube seals. Victor Reinz makes it: Part number VS50059

Yes, you need a Rocker cover (valve cover) Gasket kit. Remove the valve cover, remove all old O-rings and cover gasket, clean grooves and mating surfaces without gouging or scratching them, put the new gaskets on as per factory recommendations, tighten to the proper torque and you're done. The spark plug holes in the cover are part of the valve cover gasket kit. Any Napa, Car Quest, Pep Boys, Auto Zone will have it.

when u replace the head gaskets u must also replace any parts gasket that u remove (valve covers, intake manifold etc.) to get the heads off, they sell what is called a "Valve Grind" gasket set that is what u need, it will have all the gaskets in it u need..

it is a great deal of work. The molded gaskets breakdown with time. You'll want to change the two 90 degree elbows as well - they are available from a dealer for a reasonable price. Also, the blower gasket is likely shrunk up and /or blown out. And you might as well replace the valve cover gaskets too as they leak oil as they breakdown with heat and time.

I did all of this on mine. Even as a professional, it took me a good 6 hours.

Are you sure the Valve Cover and not just the Valve cover gasket??
Any ways go to Auto Zone and pick up the Valve cover gasket, RTV Silicone selant, Gasket Scraper, and a can of Brake parts cleaner spray.
Disconnect the battery cable from the negative battery terminal, Remove the items which are in your way: Pull the spark plug wires off the spark plugs and remove them from their brackets, remove the PCV hoses, and remove the throttle cable from its brackets and position it out of the way.

Loosen the fasteners in this order, I believe there are 11 bolts holding the Valve cover down. Remove one bolt and count to the next 5th bolt and remove it and count to the next 5th bolt and remove it, do this till all the bolts have been removed on a circular pattern. Carefully remove the valve cover from the engine head.

If your just going to replace the Valve cover gasket,  Remove the gasket from the valve cover. Thoroughly clean the mating surfaces of the valve cover and the engine head. Use a gasket scraper to remove all traces of old gasket, and then use the Brake parts cleaner to clean any remaining oil from the surfaces.
If you bought a new Valve cover, Apply RTV silicone sealant to the gasket and engine head around the cutout areas of the valve cover. Note you still have to clean the heads on the engine. Lay the new gasket in the groove in the valve cover.  Reinstall the valve cover with its new gasket on the engine head. Tighten the bolts in the same order you removed it in. Do Not Over Tighten the Bolts that hold the Valve Cover down, you'll crush the new gasket and will get an oil leak.
Note: If the valve cover does not come off the engine head easily, use a block of wood and a hammer to bump it in an attempt to jar it loose. If absolutely necessary, you may slip a flexible putty knife between the head and the cover to break the seal.
If you purchased a valve cover gasket kit, don't forget to replace the small rectangular gasket and the spark plug seals as well while you have the valve cover off the car. You may buy some Brake cleaner to clean off all the oil which has leaked all over the engine. 
DO NOT attempt to pry the cover off the head using a screwdriver or chisel. Be very careful not to introduce foreign matter into the engine. If you get anything (dirt, metal shavings, bits of old gasket) into the engine. 
DO NOT over-tighten the valve cover fasteners. On the engine, the fasteners need only 17 to 34 in-lbs of torque.

Your A/C system has a leak in it. all system has a slow leak and common, You can get a re-charge kit at Auto Zone to save some money, but if your A/C needs charging again in 2 weeks or less then there is a larger leak due to a bad seal and is cheaper to have a A/C shop locate the leak and replace the seal that has gone bad.
Good luck and hope this help. keep me posted, be glad to help.

The first step is to remove all the parts that are in the way of you being able to remove the valve covers. (Ex.: air intake, loose wires etc.) Then you will need to remove your valve covers (using basic tools) and be very careful to not let anything get on your lifters, which your valve covers protect. Once you have the valve covers off compare the new gaskets to make sure they are the right size. Then remove the old gasket and replace with the new one using a high temp gasket sealant (available at any auto parts store) to attach the gasket to the valve covers. Then tighten down snug and check for leaks after replaced. 

Whoa! Never remove the oil filter while the motor is running. Alot of vehicles have valve cover leakage and it is easily repaired with a new valve cover gasket. It is completely normal for the dipstick to be dry until the motor is off and all oil has drained from the upper compartments of the engine including the area where the oil lubricates the valve guides. Most mechanics will place the vehicle on a completely level area and then wait 15 minutes or so after the motor is off to check the oil. The dipstick will always show that you have low oil if you check it while the motor is running as the oil is elsewhere doing it's job. If you replace your valve cover gasket be sure to not overtighten and tighten in a random crisscross pattern so that you have uniform pressure all along the gasket. There are torque guides for this and you can usually get them from your local parts house. Buy a good torque wrench also.

On valve cover, there are 8 or more screws, maybe one or two connect to small part to hold either hose or others, remove those screws around the cover, the cover will loss.

When you change the gasket, you have to clean both cover and head surface, make sure it is completely clean, then use grease instead of glue, it is much better, when you tight it, do not make too tight, it will break the gasket but also not too loss, it will leak again, you have to do just right.
Hope this can help you, if you have other question, post it, I will help you.
