The reco is easy.. I have done EA twice, and EF once.
Grab yourself a reco kit, pretty sure repco have them, making sure you say its for an EA as the lifters are bigger.
Remove all lifters from the rocker gear using a center punch to tap them out of the rocker arm.... take your time.
Have a little container filled with paint thinners nearby.
Take apart each lifter by removing all the plastic clips, they will probably all snap into bits, thats normal. As you remove the plastic, place all metal parts into the thinners.
Each lifter should have a flat little piece of steel that makes contact with the valve, as well as a housing, piston type insertion and a small spring. DONT LOOSE ANY!
Give them all a nice swirl around in the thinners to get all the oil off, is ok, you can mix all the parts up.
Then take them all out and let them all dry.
Its now time to put the things together again.
There are two replacement plastics for each lifter.
Place the spring inside the housing, and then the piston like piece inside the housing. Then just clip on the little plastic ring to hold them together.
The next step is to attach the little flat piece of steel (valve contact) using the other larger clip.
Once they are all done, re install into the rocker arms, and bolt it all back onto the car.
When you start the car, every lifter will be making noise, and you will probably shit your self. This is normal as they all need to build up pressure, takes about 15 mins of running for them to stop tapping.
A picture would help me explain this soo much better, but I guess once you take it apart you will know what im talking about.
Hope this makes a bit of sense.
