Now no reason to get BITTER!

Everyone likes what they like, and it's just personality.

I and other users have had multiple problems with running Autolites in Chryslers. Now I haven't tried NGK so no dis there. NGK makes a great product period but they were built for air cooled motors. When users have problems like this it's in their best interest to resort back to OEM and go from there. Two many people have their own opinions as to how the American motor should run. Many of them fail because they don't understand the concepts of finicky machines. (then again there are stupid ones too)....LOL

Then you have the shops that install crap and charge the max for something that they get a discount on. They get kick backs to use the product. Most of this (crap) will fail very quickly and you take the vehicle back just to get charged some more $.

Some users have had luck with Autolites and some have not period. This is why starting from the basics when there is a problem is suitable. As you can see the problem was taken care of.

 

Brief description 010:

Get a manual!

On the 5.9L and 5.2L you remove the fuel line at the disconnect fitting toward the rear of the motor off the fuel rail. This requires a special tool. You do not need to remove the fuel rails. Disconnect the TB sensors and linkage. Remove the TB. Remove the T-stat coolant neck and disconnect all other sensors like the water temp and air temp sensors. There are some brackets that need to be removed on the front of the motor. The distributor and oil pressure sensors need not to be removed as they are in a cut out of the manifold. Loosen all intake bolts slowly in the torque order (just reverse) according to the manual. After removal of the intake you can flip it over and there is a cover. It is mounted by several bolts. This is where the Plenum Gasket resides. You just replace it and add a little RTV sealant (I like the gold one) and you are good to go. Do a full clean job before replacing the cover. Torque to specifications and in order.

Installation: Clean all mounting surfaces with a good cleaner like brake cleaner because it leaves no residue behind. Be careful not to use screw drivers and such that could gouge into the metal. Replace the gaskets on the intake by placing them on the motor and but a little RTV sealant in the corners between the block and the heads as to mate the gaskets. Lower the intake manifold onto them.

Now you are supposed to replace the bolts because they have been torque. Most people don't do this but it is recommended. If you torque the manifold down using torque specifications and in the right order then I would over torque them by 2 lbs to insure a stretch on the old bolts but this again is not advisable but should work.

Installation is in reverse

 

Yeah thanks, Just for other people that will read this thread
