How do you replace a valve cover gasket?
First, make sure to clean off any crud build up around the general area where the valve cover meets the head. Doing this will prevent too much crud from falling into the top of the head when the cover is removed.
Next, you will have to remove the two nuts holding the air filter housing onto the valve cover. There should be two nuts holding this bracket down. Don't loose the two metal caps that sit on top of the rubber washers. Without them the nuts will bear down into the rubber washers which will wear them out quicker.
Remove the (3) nuts holding down the valve cover. Be sure to save the metal bracket that holds the clutch cable, if you still have that bracket.
With a flat-head screwdriver or other flat object, gently pry around the junction of the valve cover and head to free the valve cover. If this is the first replacement of the valve cover gasket the head surface under the gasket should visibly show where the gasket was leaking.
Be sure to use a putty knife to thoroughly clean off any gasket remnants from the surface. You can use a little solvent to try and help free some of the residue but DO NOT allow any of this fluid to mix with the oil or get on any of the rocker assembly.
Now's the hard part, getting the old gasket off of the valve cover. If yours is anything like mine was then it's rock hard and a complete pain in the butt to get off. I had to use a small flat-head screw driver or a phillips-head to kinda chisel out the gasket from the groove it was lying in.
After removing the gasket and thoroughly cleaning the surface down in the groove I removed the rubber washer type seals where the valve cover bolts come through the top of the valve cover. This will most likely need to be replaced too. To save money make sure you buy the gasket with the replacement rubber washer type seals. I can't remember exactly what they're called but you should be able to recognize them when you see them.
Thoroughly clean the inside of the valve cover from any crud and you might as well clean the outside too while you have it off.
Place a small bead of silicon gasket maker into the groove of the valve cover where the gasket will sit. Also place a small bead on the top of the head where the gasket will sit. DO NOT put so much that it will bleed into the rocker assembly and mix with the oil when you tighten down the valve cover.
After you place the new gasket onto the valve cover place the cover back onto the head. Put the new rubber washer type seals in their three holes and put the nuts on finger tight. DO NOT forget to put the clutch cable bracket back on or your ground wire that came off the right side of the cover.
With your 10mm socket tighten down the middle nut first and then your outside nuts. Make sure it is tight and secure.
Put the air filter assembly bracket back on and be sure to put the steel caps on over the rubber washers so that the nuts do not bear down into them. Be sure everything is tightened down and you're done. Congradulations!!!
The rubber washer type seals are termed "grommets". There's a valve cover gasket w/ grommets kit that is sold and is cheaper to purchase than purchasing them seperately.
To replace the valve cover gaskets on a 2003 Jeep Liberty, the valve cover is removed. The old gasket is then removed from both the valve cover and the manifold (old gasket will come off in pieces on both sides). Then spread the sealant on the manifold, place the new gasket on, then put sealant on top of the gasket and replace the valve cover and bolt down.
Should you need to replace the valve gasket when you replace the timing belt on a 2000 Hyundai Elantra?
No you do not.... the valve cover only bolts to the head, and the head bolts to the block... True- these are two different jobs. When changing your valve cover gasket you may just want to ensure that your head bolts and lifters are still torqued down properly. Otherwise, DO NOT remove the head gasket if you simply want to change the valve cover gasket. when replacing the head gasket you should replace the valve…
The valve cover has to be unbolted from the head to be removed. Any hoses or brackets in the way needs to be removed, then lift the valve cover off. You may have to pry gently in several places to loosen the cover. The old gasket may have to be scraped to get any pieces off of the cover and head. Reverse the process to install the valve cover gasket on the 96 LeSabre.
Pretty easy. Remove the valve cover by loosening the 5 bolts holding it in place. There are a couple of hoses and another screw that will need to be removed as well. If the valve cover has been on the engine for some time, you may need to apply sufficient force in breaking the valve cover/gasket loose from the engine. The gasket lies beneath the valve cover along its edge. The edge is lipped so…
Drain your oil and change your oil filter but do not refill your oil yet. undo the bolts on the valve cover that is leaking and remove the valve cover. remove the old gasket and clean the valve cover. make sure there are no cracks or anything on your valve cover, if so you may need to replace the cover. fit the new gasket on the cover and put the cover back on. now put…
The replacement of the valve cover gasket is relatively similar on 4 and 6 cylinders engines. Remove the nuts on the valve cover, tap the side of the cover to break it free. It is a good practice when you replace the valve cover gasket to also replce the grommets for the valve cover nuts as well. Clean each surface of the head and valve cover, usually wiping with a clean cloth will do. Sometimes…
