Default Replacing Head Gasket

What parts (beside a head gasket) do I need to replace a headgasket on a '98 EJ25 ?

Is this a difficult job to do ? The engine is already out of the car.

Do I need to degree the cams ? Or is there a way to lock them in place while I put the gasket on ?

Thanks,

Rob.

Cams have to come out on the DOHC heads in order to get to the headbolts. Good thing the motor is already out. It'll be much easier that way.

Have fun,

The T-belt has to come out. The Haynes manual will give you some idea. The head will have to be checked for flatness and cracks as well as the block. It is about as major of a job as can be done without pulling the block apart. Why is the head gasket leaking? Did the engine overheat?

Hey, this is joe from Pa. Last november I replaced the head gaskets on my '97 ouback EJ25, DOHC engine. Search under my login name joemamad for the posts. By the way the front main seal "fix" I tried is holding up very well, no leaks! (see post) good luck take your time and be thorough, Shell be better than new when your finished. This new gasket is my third in two motors and it is lasting the longest so far.

Make sure both surfaces are undamaged/smooth. If you have to get it machined!

That really does not sound to good unless you are racing.

Not racing on the track, just driving pretty fast a-lot. Sombody's got to show that these little wagons can fly! In my defense, the head gaskets have been redesigned since the first two blew and I was meticulous in the reassembly. I didn't bother to open up the first engine, just bought a used one and droped it in. I wasn't going to buy another in the end the price was close but I could be sure of what is going on in there.

To reply: yes I do drive fast and hard but not any more so than I have in various other cars. This one is the most fun and I haven't blown any other gaskets or engines unless you count that time.....
