Default Any way to get cam sprocket back on without pulling timing cover

Like the title says I'm in the process of reassembling my motor after replacing the head gasket.
I am trying to do this as cheaply and easily as possible. Is there any way to get the cam sprocket back on without pulling the timing cover? I feel like I'm already in way over my head and would really like to start putting everything back together again without taking more stuff apart or buying more parts, and gaskets.

Is the chain tensioner hydraulic right? so i could potentially pull the chain up tight enough to put some pressure on it and push the tensioner back in a little bit?

I have a few ratchet straps hooked up to my ceiling pulling up on the sprocket and still cant get it onto the camshaft. I'm like half a millimeter from it going back on....
Anyone have success putting the sprocket back on without the cover coming off?


additional if someone has can send me some pictures of their complete Z24i engine it would be much appreciated.
Its been a few weeks since I disassembled it and some of these brakcets are confusing me on where they go.

shoulda pushed a wedge between chain to keep it tight before shprocket removal and to jam tensioner, this keeps chain in place while you do head so you dont lose timing. Can you do this now? I don't know, good luck, I hate pulling front cover.

Check out my rocker arm noise videos on youtube for the ka24e. While not exact, they are similar and i go over removing and installing the sprocket without removing the timing cover.

hey so in your rocker arm video you had to loosen the rocker shaft some to get the sprocket back on the camshaft?

well i cant get it back on, loosened both rocker arms from the back and the cam still won't budge on. Looks like I'm going to have to pull the front cover FML. I'm really worried about my ability to find the right mechanical timing. is this an interference design. Any tips for removing the distributor and keeping it in time. I had the head milled with the camshaft in place so i wouldn't lose the time and now I'm in way over my head.

Pull the cap on the dissy and note which direction the rotor is pointing. It will turn a little when you pull it out. Only 2 ways to install it back in. Correctly or 180* out. You will have to time again. You can take a paint pen and mark where it is at now, so when it goes back together it will be real close.

Are you sure that you have the plunger for the tensioner is pushed in? You can look down the pass side of motor and see it. You shouldn't have to pull the front cover unless something is broke or the chain came off the bottom sprocket. Even then you can drop the oil pan and fix that.
