Cylinder heads require 33 ft #s & 90 degrees following... Lower intake is 115 inch #s.
Mitchell On Demand states 44 lbft & 95 degrees for 1999-2003 Chevy Malibu cylinder head torque specs for V6 3.1L, lower intake manifold 62 inlb then 115 inlb tightening in a circular pattern starting from center.
It is between $65-$85 for the gaskets.
The intake gasket is the gasket that conncects from your air filter into your intake manifold
Yes, you need to replace your intake gaskets.
6 gaskets
bad vacuum hoses or leaking intake manifold gaskets.
The year, engine size and if it is the intake manifold or an exhaust manifold gaskets would help.
You will need a intake manifold set and possibly a plenum gasket set.
Which intake gasket? There are two gaskets between the intake manifold and the heads, one sealing the manifold to each head, plus a couple front/rear gaskets that seal out the crankcase oil. To get to those gaskets you need to remove the intake manifold. That involves removing a lot of peripheral stuff that's mounted on the manifold. Another gasket is between the manifold and the throttle body. That gasket is a lot easier, just remove the bolts holding down the throttle body, clean both surfaces and put the new gasket in place. If the engine is idling fast, sometimes it's just the EGR valve gasket. That's just two bolts then clean the surfaces and replace the gasket.
No, You don't put anything on Head, Exahust or intake gaskets. CJ actually you do put a 1/8'th inch bead of black silicone on the gasket to ensure no leaks occur and it also helps hold the gasket in place when your putting the intake manifold on. I'm a ford master technician, you ALWAYS use silicone when replacing intake and head gaskets. =DK
No, you need a new gasket. About the only gaskets that may be reusable are valve cover gaskets some engines.
An intake manifold gasket is a malleable material that is set between the air intake manifold, the cylinder heads and the block in a gasoline powered internal combustion engine. Intake manifold gaskets prevent leakage of air or the air-fuel mixture by sealing the gap between these various metal engine parts.
Remove the intake manifold retaining bolts on your 2003 Chevrolet Malibu. The manifold will come off. Remove the manifold gasket and clean the surface. Put the new manifold gasket on and reverse the process.
