temporary motor? just swap longblock?

replaced both camshaft sensors and crankshaft sensor and motor wont turn over itll just crank, and if i give it gas it just bogs out and eventually die. just opened the valve cover last night and its got skipped teeth on the chain, about two teeth and chain shows hella slack. so yeah... and i need the car running

I would put a new chain and tensioner on there before I go to the next step of getting a new motor. Can you do this on your own? This is cheaper than swapping in a new motor.

ok, so this idea did cross my mind, but i heard that removing the crank pulley was a biggity bitch and that it was just time consuming to replace the chain and tensioner, and i live in mini soda, so its freezing balls at the moment... so dont really wanna be in the garage too long lol but on another note, since the tooth skipped and say there was p2v contact, would it still be operable if/after i change the chain and tensioner and re-do the timing? or would the motor need to be re-built before using it again?

The motor should really come out when your doing a chain and tensioner, to be honest thats probably whats wrong if it skipped a tooth. The only way you can just swap motors is with the exact same short block, if you try to swap a different motor you will need a way to tune the engine as they are all slightly different.

thats my point, isn't it faster to swap in a running motor than it would be to replace such and such and then get it back in, and then have it still not work? i mean, i get what you guys are trying to say, but if its gonna take me the same amount of time to do both, i might as well swap the motor cause id be heading down the same road anyways, right?

alright... so i think i will be changing the chain and tensioner first and also the guides, but i have read that it would be a good idea to replace the top guide with the si top chain guide cause its bigger/wider? either way i'm still worried about removing crank pulley, is there any special tricks or tips you guys may have, besides the usual pray it comes off? lol i have been looking to see if there is any special removal tools but just see the usual removal tools.

so... just took out the timing cover and removed the timing chain to compare it to the new one i got... and hot dang, the chain is stretched. so i bought an oem tct, timing chain, and the two chain guides on the block, but i read on another forum about the upper chain guide from the k20z3 p/n: 14540-RAA-A02, which is wider than the stock one on the tsx motor. so i just wanted to know if anyone else has used this chain guide on there k24a2s, and is there any modifications that has to be done? it looks like it wont be an issue, but just wanted to make sure. i will try to take some pics to show comparison between the guides and the chain stretch. thanks for the info/advice guys.
