So my engine mounts and maybe trans mount have seen their last day today due to the fact my engine is almost smashing into the hood and just falling back into the engine bay. Is it safe to put a block of wood on a jack and jack the engine up by the oil pan? Or is there some other way to lift it to replace the mounts?

That's pretty much the only way to do it, use a 4x4 block and do one side at a time.

That is how I did mine. Jack and a block under the oil pan and another Jack and block under the tcase somewhere

Do one engine mount at a time or you will have a 5+ hour job

awg

its always the LH mount that gets stuffed, as it has a different force to contend with...and exhaust mani heat on an XJ

on a RHD version, its 10min to do the RH mount...the LH mount is excruiating

Yeah it is shot lol no more rubber left basically and can move my engine by hand.

The left side mount always goes first because the engine torques and lifts that side. The right side is being pressed down. Any engine always torques opposite from crankshaft rotation. Fighter pilots in WWI found out their planes turned quicker and faster when going with that engine torque. It was even more pronounced in WWII with higher performance engines. The P38 Lightning had engines that rotated in opposite directions to cancel that torque problem. Even marine engines, even though they are mounted backwards, have a mount problem. It's called Physics!

No wonder my little Honda Civic is so slow... all 80 of its lb/ft are trying to go backwards and the car is trying to go forward

Laugh all you want, but that's why transverse engines lift the front end on acceleration.

Oh I know trust me. I wasn't mocking you or your post just making a joke

dave1123

I know. I was just ragging on ya.

If your doing motor mounts it is highly advised to do the trans. Mount too. From the sounds of you motor mounts your definitely going to need the trans mount too

dave1123

Do the trans mount last so you don't twist it doing the motor mounts.

XjJunky

The trans mount should be loose when you do the motor mounts. If not its going to be hell trying to get your engine lined up. In all reality it doesnt matter which you do first as long as all mounts are loose

I swapped my trans mount first and left it loose. Wouldnt have been possible to do the mounts without the trans mount being loose.

I was assuming it was already broke!
