No, just pull the intake manifold, thenfish the lifters out.
It's not recommended to change just the lifters. The cam and lifters should be replaced together. To get at the lifters, you can remove the rocker covers and intake manifold, loosen the rockers enough to get the pushrods out, then pull out the lifters.
pull off the intake and the valve covers. then take off the rockers and pull up the push rods. then pull up the lifters using a speacial tool from the parts store. be very careful keep them in order. dont get dirt on anything!
You can just pull out the old one and put in a new one. However, I've used the Comp Cams 292, and it wants more compression, more gear, and a looser converter than stock.
Pull the plastic trim that surrounds the radio and center stack, remove the screws that hold it in, pull it out and unplug it. Reverse to install.
pull the cam and lifters
If the lifters are noisy, usually replacing lifters alone won't fix it. 2.9's dump oil internally, as the cam bearings wear. excessive oil is lost between the cam journal, and the cam bearing. Not enough oil actually reaches the top end. Additionally, you have to remove the cylinder heads, to get the lifters out of their bores. That's a lot of work for a repair that may or may not work. You may as well pull the engine, replace the cam bearings and cam, and lifters. Since you've gone that far, you may as well install a Melling high volume oil pump.
Yes
Behind the head light itself. is a plastic ring, this screws to the housing around the element. Unscrew it,pull the element out of the head light bezel, unplug the element and install the new one. screw it all back together. you will need no tools.
this is a big job , pull off intake manifold and the heads to get to the lifters , and when you put it back together adjust your valves . if not done correctly you could ruin engine.
You need to install a spark plug heli=coil. It is new threads that go in the head. If you aren't familiar with it you may have to get a mechanic to do it. You may also have to pull the head but it is better than buying a new one.
if the engine is removed from vehicle you need to remove the intake, the valve covers, the rocker arms, pushrods, and lifters; then you remove the timing cover, then line up the marks on the sprockets by turning the engine over by hand, then remove the cam and crank sprockets and timing chain; then pull out the cam and install the new one; line up the marks on the sprockets and reinstall them turning the cam if necessary; reverse the rest of the procedure.
Remove the four (7mm head) screws, then pull the radio out. Remove the electrical connectors. To install the new unit you will need a Tech 2 and access to the SPS system. This may not be cheap...
