I am in the process of replacing the head gaskets on an ej25 DOHC engine and I was wondering if I need to pull the cams off before I remove the heads from the block? I was reading the Haynes manual and it says to remove the cams, but they do not seem to be in the way of the head bolts so I was wondering if the removal was really necessary?

 

By the way, I am using the Subaru metal gaskets for replacement.

 

Thanks for your help.

you ARE going to send the heads out to a mchine shop to be checked for flatness and to be resurfaced yes?

 

Personally, I would have a valve job done too, so yes.

Mike,

 

Yes, you have to remove the cams before the head bolts. The cams are in the way of the head bolts.

i'm getting this strange felling your doing this while the engine is still in the car? are you?

Engine out and on a stand. Will do the job tomorrow. I'll let you know how it goes.

Pulled the heads and the cams only to find out that one of the exhaust valves is burned. Off to the shop for resurfacing and a valve job. Hope to have the heads back by next thursday and then I can put the engine back together.

Inspect that fuel injector and make sure there is nothing wrong with it.

how should it look? Anyone have any pictures? Can I use an injector out of a 2.2 to replace it?
