Default Installing new valve springs, rockers, & pushrods.

First thing you will need to do is get all your tools and parts lined up. For this project we will be replacing the valve springs, rockers, and push rods. It'* a good idea to have a extra set of valve keepers. These are very small and can be lost easy. You will also need a set of valve cover gaskets.

As for tools you will need a Torque wrench, a ratchet wrench, a valve spring compressor, a compression tester, air compressor, and a magnet. As well as correct sockets. You will need to check your car for proper size.

It'* best to start on the rear head. It'* the hardest one. That way you finish off with the easy one.

Doing this project is not hard, and takes between 5 and 8 hours. Figure on about 6 hours.

Start by removing whats in my way, like this alt. bracket. Make sure you disconnect the negative battery cable before starting this project.


Then remove the valve covers


There'* the rockers.


Once the rockers are removed you can get at the springs easy. But first remove all the spark plugs. This is where the compression tester and air compressor comes in. install the hose for the tester in the spark plug hole and connect the air hose from the compressor. This will force air in to the cylinder holding the valves in place. However, it will also force the piston to it'* BDC. There is no way to insure the valve will stay in place. So you must be careful. I suggest using the valve spring compressor to compress the spring. Then carefully press down on the valve before removing the spring. If it stays in place, then you can remove the spring. Do one spring at a time. Use a large magnet close to the springs to catch the keeper if you should drop it. Use a small amount of sticky grease to hold the new keepers in place when you install the new springs.


Once your springs are installed you can drop in your push rods. This is VERY easy. Just make sure you wiggle it around to make sure it'* seated in the lifter. Then install your rockers per the instructions that come with them. Each rocker set will be a little different, so make sure you follow them closely.


Here is a picture showing all the rockers in place. Check for the proper torque settings for your rockers. Make sure each valve is in it'* closed positions to get proper torque. Good idea to go over each one twice.


When everything is torqued correctly you can close up the head and torque the covers in place.


In this picture you can see the magnet below the spring. If you drop a keeper you have to make sure you know where it went. If it falls in to the head it can drop inside the engine. If that happens you will need to start taking things apart to get it back. It will jam your engine and do many bad things. So don't drop any.
