How do you Replace Head Gasket for 2002 Nissan Sentra GXE ?


Big difference between valve cover gasket and head gasket. To replace head gasket, you must dissamble top end of engine and send the head out to be resurfaced and then install new head gasket. If it is a leaking valve cover it is much easier. Simply dissasemble and then clean valve cover and top of head from all debris and remove all old gasket material. Tighten back down in sequence and do not over tighten. these small bolts can be overtightened easily so go in sequence just like when you tighten lug nuts by skipping one as you go around. 10mm bolts require about 10 pounds or less torque.

Replace the valve cover gasket if the valve cover gaskets are leaking or if they're worn. The procedure is as follows:--
1)First carefully remove the nuts holding the valve cover to the engine head.2
2)Then pull the valve cover off from the engine head .
3)You can use flat-tip screwdriver to remove the valve cover.
4)It will be very dirty inside so you will have to clean the mating surfaces on both the engine head and the valve cover.
5)Take your time and clean it completely.

6)You can use a bead of RTV sealant on both mating surfaces.

7)Then carefully seat the gasket to top of the engine head.
8)The gasket can only be fitted in one way. So fit it properely.
9)Then tightly Press the valve cover to the gasket
10)And tighten the valve cover nuts secure.

Replace intake manifold gasket; 4.3L V-6


do you have a coolant leak or oil leak. ive always discarded the rubber gaskets provided in gasket kit, and instead, ran a good thick bead of silicone. The rubber gaskets, ive found, can be pushed out, either when setting intake on engine, or if the engine has a bad pcv valve, pressure within block can blow them out. make sure and check pcv valve. after the new intake gaskets are placed on the head, dab a bit more on the 4 corner nubs of the gaskets. i like to use an anearobic sealer around the coolant ports, just thin layer on both sides of gasket. hope this helps.

Need to know if have to take intake off v6 2.5 suzuki to replace valve cover gaskets


yes and no, you can take the nuts loose, dont drop them! they will fall into the intake later. take the bolts loose, and you can lift the intake up, its got metal reusable gaskets. but just lift it up and with a swivel 10mm you can take the nuts off. seal under the valve cover nuts is easy to drop too, if you do you will have to pull the intake to make sure it wont run through the motor, it has a metal washer in it. but you can sneak them out without too much hassle

I found oil on 2 spark plugs telling me the head gasket is blown. Ive never replaced one before what can you tell me?


Oil on the plug does not indicate a head gasket.
It could be a bad ring, valve guide or valve seal.
A leak down test will comfirm a head gasket leak
A compresion test will confirm a ring problem.
Oil consumption and smoke indicate ring and valve problems.
If it smokes on stat up, most likely valve guide or seal.
If if smokes when you drive and let off the gas quickly from speed, then most likely a ring or cylinder wall problem.

Good Luck

I have a slow oil leak and my hoses seem fine so I think its my valve cover gaskets. How do you replace them?


try nipping up the hold down nuts or bolts first, if that doesnt work remove any hoses that attach to the cover, undo any nut or bolt remove the cover, clean it of all old gasket etc, also the matching surface on the head or heads, place new gasket on the cover with some gasket cement, also put cement on the matching head surface, replace the cover and tighten the nuts or bolts and replace the hoses etc

BLOWN UPPER HEAD GASKET


Cost will probably be around $300.00. Call a dealer and they can tell you exactly. Most of them have standard price lists for standard repairs.
