reinstall engine

[Wally]

So i have my engine ready to put back in. my tranny is out and will be put back in after i get engine in. I have engine in bay and mounts all bolted up.

SOmething is bad wrong. i have some images with tension from my engine lift still on it. when i take tension off the engine dips badly toward the back toward tranny.

This isnt normal is it? can anyone see anything from pics? i know shorter mount is on passenger side so there is a larger than normal (imo) angle toward passenger side when i take off tension.

That is normal.  Nissan calls the transmission mount the rear engine mount.  The engine weight is not centered over the two front mounts.  Holding up the back of the engine is one of the more difficult things to do when removing the transmission.  People use a cable on the hood latch (bad idea) or a block of wood between the valve cover and the firewall (still bad), but a jack under a block of wood on the back of the oil pan is probably best.  Use the car's scissor jack and you'll be able to adjust the angle when you install the transmission.

Probably why most people install the engine and transmission as an assembly, but forgot to mention that.

And, even worse, if you didn't slide the transmission under the car before you installed the engine, you'll have a hard time lifting  the car up with the engine in, balanced on a scissor jack.

There are other work-arounds but the tilting unbalanced engine is normal.

i have the car on 12" race ramps so no issue getting tranny under...

WHEW! thanks man i was seriously worried about that. 

i couldnt mount the tranny by myself; it kept rolling off my floor jack. So, 

i had to order a tranny lift..just waiting for it to arrive. i guess leaving it attacking the the engine lift for a few days wont harm anything.

I tried hard to mount the engine with the tranny still attached but i just couldnt make that happen.

I just did this a couple months ago. It really helps if you have another person. I left a floorjack w/ some wood on the bottom of the oilpan, then lowered the motor till my pops and I could slide the transmission right into place.  Last time i did it myself and chewed into the input bushing a bit by using a bolt to pull the motor and bell-housing together.

Sorry I'm late to the party but if you ever have to do it again. 

I've always gotten lucky and pulled a rope with a wood "handle" up through the hole in the tunnel as the transmission goes further back. Then tie it off when it's level and let the wood hold it in place until I can get the transmission mount mounted.
