So that's what he does! I wondered already.

Well, I have done these already and yes, the engine has to come out the bottom along with the transmission. I then separate the trans and put the engine on a stand, rotate it upside down and start disassembly. By the way, if you get to this point, seal up the other leaks on this engine. They are many. This is one of those jobs where the customer has to be committed to going all the way or not at all. At least that's the way I do it. If we can't seal up the whole engine I won't do it cause it will leak somewhere else.

Yea man. And when the flexplate comes off ya gotta get new bolts to install it.

another issue here, and i know we already know this but it's worth repeating, you need to take into consideration collateral damage. the single most important issue (to me) is the fact that the engine may "sound" different when the customer gets it back. i let the customer know that there is a good chance they'll need new motor mounts. if they come through jell filled then that's what goes back in. i will not use the solid option. a while ago i purchased a good under hood support assembly. the one i have is a bolt on and i can support the engine and transmission while they are separated. not on this particular application but i would take a good look to see if i could use this and drop the cradle not the mill.

steve, your suggestion of dropping the subframe instead of the entire engine is a possibility I suppose. I have not done that on these engine due to the many other leaks this engine may have. But you do bring up some legitimate points.

One of my techs is an ex-GM guy. He did some of these and once he tried to do it in-car. You can get the lower pan off but many leak at the upper portion too. He regretted trying to save some time.
