I would replace them because they are made to compress one time when the bolts are tightened. They are not very expensive and you can shop around for price. You could use some ATV High Temp on both sides of the gaskets as a filler and leveler, but you will risk debris going down the heads when you remove the Intakes next time. You will also have to clean the surfaces of both parts creating more work for yourself next time.

Need to know how to replace the spark plugs on a 2007 Volvo S40 with s 2.4 engine.


You will remove the upper intake manifold,be careful not to damage the intake seals,cause you are going to reuse it,From there you remove the COP (coil on plug) one for each sparkplug,11_24_2012_2_06_15_am.jpg11_24_2012_2_06_49_am.jpg

How to fix oil leaks in chevy ss impala 1996



Instructions

1. Removal

Unscrew the bolt that holds the negative connection to the Impala's battery. Set this bolt aside for later use.

Remove the engine cover to access the intake manifold and manifold gasket. Disconnect the throttle body inlet duct from the engine.

Twist off the radiator cap to allow draining of the coolant to flow more smoothly. Place an empty container beneath the radiator's drain plug, and remove this plug. Allow all of the engine coolant to drain into the empty container. Replace the drain plug once you are finished.

Tag all of the electrical wiring and hoses before removing so that reconnection is precise to factory settings. Remove these parts, individually, from the intake manifold.

Loosen the bolts that hold the intake manifold to the Impala's engine block. Lift the intake manifold from the block once all bolts have been completely removed.

Use the flat-head screwdriver to pry the old intake manifold gasket from the engine block. Discard this part once you have removed it.

Clean the engine block thoroughly with the engine degreaser and linen cloth. If necessary, use a gasket scraper to remove excess buildup and grime.

2. Installation

  • Coat the top and bottom of the new intake manifold gasket with a chemical sealer so that it bonds to the engine block securely. Position this new manifold gasket so that it lines up perfectly with the cylinder ports of the Impala's engine block.

Place the old intake manifold on top of the newly-installed manifold gasket until it aligns with all of the holes of the cylinder flanges and manifold gasket.

Attach all of the bolts with your hand to the manifold. Once all bolts have been positioned, use a torque wrench and apply 15 foot-pounds of pressure to the bolts to secure the manifold into place.

Reconnect all of the necessary hoses and electrical wiring to the intake. Pour the engine coolant back into the radiator.

Reattach the engine cover on top of the intake manifold and engine block. Start the Impala's engine and check for any leaks around the new intake manifold gasket.

Want to replace plugs and ignition wires on a 2004,V-6, 2.7l Tiberon


The air handler you describe is called the 'surge tank' (or I perfer to call it the intake manifold). This manifold must be removed to access the 'rear bank' of plugs & wires on the 2.7 lit V6. There are three or four 12 mm bolts on the rear side of this tank (you'll have to feel for them) and the others are directly under your nose up front down the center of the engine (two long 12mm, three short 12mm and two 12mm nuts. You will want to purchase a new gasket for this manifold (recommended because reused gaskets have been know to leak - rare - but happens). When you put it back together, start all the bolts/nuts finger loose first, do not tighten the rear bolts until after you have torqued the main center-line manifold bolts first ( I believe the torque is 14 to 17 ft lbs) If you don't do these first, you could crack/damage the manifold.
