Default question on repacing heads / head gasket

Does the engine have to be pulled for this job or can I get to the heads with the engine still in the car ?

Which engine? Some of the cars pulling the heads with the engine is isn't too difficult. Others, like the DOHC's, I wouldn't even think about it. The two hours it will take you to pull the engine will be made up on the back end with dismantling and building it out of the car. At this point, since I can pull the motor in under an hour, I pull it for any major work...

I have an SOHC 2.5 in a 1999 Forester

- What all needs to be removed from the engine to pull it ? ( I have started down the path already by pulling the AC condensor, radiator, battery, air filter housing, power steering pump and alternator.

- I am assuming that I would need to invest in both a "cherry picker" and an engine stand

Your thoughts/advise is greatly appreciated.

Next you need to pull the heater hoses, brake booster, starter, and fuel lines. It is a good idea to disconnect the fuel pump and run the car until it dies to relieve fuel pressure before removing the lines.

From there, it is just the bolts that hold the engine to the tranny, the engine mounts themselves, and the pitch rod...

Doing a SOHC Ej25 in the car is possible, but still mostly a pain. I would remove it...

I will pull it.

Do I also need to remove the overhead manifold, throttle body and A/C Condensor ?

The manifold can be removed after the engine is out of the car. But you will need to remove the intake plumbing and MAF, as well as the AC condensor. The condensor can just be bunjied into the corner where the battery went. It doesn't need to be vented.
And I also forgot the exhaust manifold...

Oh,
And get the Chilton's guide or an FSM before you remove the heads. You want to stick to the very specific torque pattern or you risk warping the heads...

I already have the Chilton.

No way I could work on cars without those wonderful books !

So do I pull the AC Condensor, overhead manifold and throttle body prior to lifting it out.

I get nervouse taking everything apart because I have to put everything back together. Tear down is easy

Are you sure you have to pull the brake booster? Also I would pull the radiator for sure.

How would you propose to get the motor out with the booster line still attached to the back of the manifold? You just remove the line.

And he already has the radiator out. He asked what else do I need to do...

I cannot get to the back passenger side bolt on the AC Condensor. It is blocked by the overhead manifold. There is not enough clearance to get a socket onto the bolt. So looks like I will have to peel a "few more layers of the onion" while the engine is still in the car.

Hmm, I might be confused. Are you talking about the slave cylinnder, or the brake booster which is attached to the brake petal through the firewall? For the slave cylinder, I just unbolted that but never discharged the system.

Im talking about the AC Condensor on the front of the engine (drivers side). It located next to the Alternator.

(oops) I just realized you were not replying to my last post. Please ignore this.

Mike,
Are you trying to remove the bracket or the condensor itself? You should be able to get a box wrench onto that last rear bolt to remove the condensor. Don't try and remove the bracket. I guess if you get too frustrated, you could remove the manifold. It is coming off later anyways. Just plug the head ports to keep the crap out...

Randy,
If you look under your hood, there is a hose that runs right next to the master cylinder to the back of the manifold. That's the hose. You shouldn't have to unbolt or discharge anything. It's just got a spring loaded hose clamp on it...

hmmm

That is a good question. I will take a closer look tonight. I do believe that I am taking off the bracket. I thought the condensor was part of the bracket.

Darn..I already vented the AC. No problem though....I have a vacuum. I will also need to spring for a new dryer.

I'm going to show my ignorance here....but what is intake plumbing and MAF ?

I thought the thing next to the alternator was the a/c compressor, and the thing that looks like a smaller radiator was the a/c condensor. I could be wrong though...
