Can you change the cams withouth removing the engine?
Would be very fidgety id imagine, but still.. removing the entire engine isnt exactly a walk in the park
Id rather have the heads out todo it, but you have to remove the whole thing to get the heads off
It looks possible todo with the engine still in place, and am thinking of doing it with my timing belt..

^ Yes. I've done it a couple of times now with the engine still in. The hardest part is dealing with Cyl#4 (drivers side firewall). It's very close to the frame rails, so you gotta squeeze in there to do the lash and such. Hope you don't have Andre the Giant sized hands!!

^ Score!!
Will be calling a few local places in the coming weeks
Really it would be the best $ per kw improvment.
Is that really a problem?? My hands are on the larger side..
Is it something really difficult (would need a small handed friends help?)

You can always unbolt the two motor mounts and jack the motor up with the transmission to get alittle more room.

I did it with the engine in and I regret doing it that way. I recently looked at the procedure for pulling an NA subaru engine. I am now 100% sure that I can pull the engine, swap cams, and replace the engine faster than I can do the cam swap with the engine in place. You will need someone with crazy small hands to lash cylinder 4, if you decide to leave the engine in the car.

I like that idea, did you do that?
Just woundering how much room I would have, and how much I would need.

It just sounds like a BIG hassel, to take the engine out to change a cam!
Wiring, coolant, fuel lines, vaccume lines, intake, exhaust, throttle cable etc..
I just sounds soo much easier to unbolt the little rockercovers, take off the rocker arms, cam cover and thats it...
I will be doing my timing belt at the same time, so access to that area would be easier. Cam covers, belts will already be off.
Anybody else done any of the 3 methods (as is, lifted, removed)

Pulling an EJ253 is trivial:

1) Take off intake (and pop brake booster line off), take out battery
2) Dump and remove radiator
4) Disconnect 4 wiring harnesses, remove positive lead from alternator
5) Unbolt power steering pump and flop it to the side
6) Unbolt AC compressor and flop it to the side
7) Disconnect fuel lines (2 quick fit connectors)
8) Disconnect headers
9) Unbolt from tranny
10) Pull engine


Right now, my record is 45 minutes each way. I think that'll come down to 30 minute with some practice.

If your going to do the "unbolt the motor mounts" method... don't undo both of them.
I tried it, and like Williatty, regret doing it. The bolts are NOT trivial to get back into the mounts.
Royal pain! If I was to do it again, I'd unbolt just the drivers side motor mount, and then just rotate upwards that side with a jack. Leaving the passenger side in place.

FYI, this last time I just did a Cam Swap (last weekend) I left the motor mounts in place and managed just fine. I'm 6'0" tall with a typical build and typical sized hands. It was indeed snug, but doable.

Thanks
I suppose I dont know how 'snug' it is, so find it difficult to justify removing the engine engine..
Found a decent write up, but still looks harder than getting in there.
The only comfort coming from ripping the enigne out, is that I can do the timing belt with ease.
If left in, id still have to remove the radiator todo the timing belt.

Nope... you can leave the rad in to do the timing belt.
You only need to drop the 2 fans.
