Advice, please

Hey all, my engine blew back in July, I'm FINALLY getting around to swapping a new one in. I have everything out and an trying to separate the engine and trans. Since the motor basically blew up, severely, I cannot for the life of me get the crank to turn with breaker bar to access the flex plate bolts on the access port on bottom of tranny. I have already tried dropping the oil pan to see if something's blocking and I can't really get to anything. This thing really blew badly, cracked block, shredded internals, shards of metal everywhere. Wondering if crank is wedged or valves/something in the head is getting in the way. But I cannot get the crank to move a millimeter.. any suggestions?

Drop the pan and pull valve cover, unblock it.

If you have to pull the heads off. It’s not much work once you have the valve covers off. You just need the correct triple square/spline drivers. It doesn’t sound like this engine is being revived so just keep pulling bits off till it frees up.

It also takes at least a 2ft breaker bar to actually turn it over normally.

just pull the trans off the engine, it'll slide right off if remove the intermediate flange shaft. That;s wjat I had to do when replacing my seized engine.
P.S. pic:

take a look at it, there's a shaft going through the trans, you need to pull it out, it's only 3 bolts holding it to the trans, take a look at the s-tronic manual.

Yeah that's fair, the other engine turns with ease, albeit trans is attached to blown one. I'll start teardown. Thank you both

Mine has 6 torx bolts attached to flex plate.. not sure how it would just slide right off

flexplate and dmf will stay with the engine. dmf is not bolted to the trans.
P.S. this video will help you understand what I'm talking about:

don't mind that it's an a6 with zf 8hp, the concept is the same, all B8+/C7+ Awdi have mushroom type dmfs/torque converters with intermediate flange shaft going through them. That shaft is what;s stopping you from pullin the engine and trans off each other besides bellhousing bolts

I would only do this if you want to replace your diff oil.....

I am indeed replacing with new fluid, has 100k figured I'd do that and trans fluid service while it's all out. Perfect, thank you both!

it doesn't leak out of there it the trans is reasonably level.
@das4, make sure to post some pics and checkout mine in my engine swap thread, too if you haven;t already.

Do what @fastboatster said. It’s the only way without disassembling an engine you don’t care about, which may not work either. There’s nothing wrong with the method of separating engine from trans.
