Time for a new engine on my LS

[fudge12]

It looks like my engine is burning oil and the timing chain seems to be going. When ever i let the car idle and then stomp on the gas (WOT) I hear a loud metal on metal clank and my buddy (MTA mech.) immediately said timing chain. It doesn't happen when I baby the gas, but I can hear said chain knocking when driving on the highway next to the center divider with the windows down. Sorta like a light metal tap. Anyway, we plan to replace the engine in the summer. Can anyone provide a few pointers on getting the engine out without running into trouble?

Aside from my mechanic knowing what to do, does the PCM, cluster, and PATS need to be remarried after an engine swap? Or would the car run without any issues?

00' v6 @ 150k miles.
Thanks!

Since the only parts of the LS engine that seem to fail are the coils, cooling system and 1st gen timing chain tensioners, are you sure you don't want to just change the timing chains and tensioners?

and 1st gen timing chain tensioners

1st gen V8 secondary tensioners go out.

Fudge has a 6. The V6 has no secondary chain.

you would only need to marry the cluster, keys, and PCM if you also ended up changing one of them out too.

as long as you use a compatible motor, the PCM and cluster wouldn't know it was a different motor...

That's a relief. Now, what would be the easiest way to get the motor out? Drop from bottom or pull from top?

 

[1LoudLS]

easiest way would be right out the bottom, but you need to have the right equipment for that way to be easier. the car was designed to have the motor put in and pulled out through the bottom, its been pulled out through the top before but I would say its easy.

 

[fudge12]

We do have access to an engine crane hoist, so pulling it out through the top would be better for us. I just hope things go smoothly. Anything I should do/replace before dropping the new motor in? Last thing I need is to pull the motor out again later down the line.

Start with fresh VCGs, coils, and plugs maybe? If I was swapping the V8, I'd do those and the tensioners while then engine was out (obviously you don't have secondary tensioners)
