PSA: Removing the cylinder head with exhaust manifold on

I needed to remove the cylinder head and was having trouble removing the exhaust manifold the way the Bentley manual described, so I was able to remove the head with the exhaust manifold still bolted on. You need to be pretty strong to lift the whole thing out at the awkward position you're stuck with. I actually did this by standing on the rim of the engine bay. To do it right, you need to put your PBR hat on and be a resourceful redneck.


Remove intake manifold as usual.

Remove windshield washer fluid tank and air pump.

Disconnect the cat-back exhaust (near transmission) from the cat pipes. You don't need to take the exhaust off.

Mark/identify with crayon, and remove O2 sensors (not strictly required, but you don't want to bang them around. I couldn't get the post cat sensors off so I just left them on. Be careful!).

Go through typical head removal steps - i.e. removing head bolts, etc.

Put a piece of wood on the rim of the engine bay where the hood closes, this is where you'll sit the cylinder head.

Lift the head up an inch or so, then lift up and towards the front of the car. Be careful not to slam the O2 sensors on anything.

Set the head on the plank of wood and remove the exhaust manifold nuts.

Note: this is not the ideal/reccomended way to do it but if you're having trouble doing it the right way, this might be an option worth trying.

Yes, I always take the head off with the exhaust manifold attached. I also have use of an engine hoist to lift it.

It helps to have a second person handy to move it too.

Engine swaps, HG, GM & ZF tranny rebuilds.
