Hey everyone! I plan on doing my very own hockey puck mounts on thursday. I just wanted to know from someone who has done it, what technique did you use. I'm trying not to completely remove the engine. Could I just put a jack under it or use an engine picker to hold it up while I do this?

I replaced my engine mounts and I just used a picker to lift the engine enough to swap the mounts. The motor had loops bolted to it to make lifting easy.

DO NOT use a jack under the motor you will dent the pan.

Keep an eye on the tranny as it gets near the top of the tranny tunnel AND you will want to pull the cover off the shifter and make sure you don't have the shift lever damage the interior console trim as you raise the motor.
You should be able to jack/support underneath the tranny bell housing...

i did hockey puck body mounts in my Scout :p
I have two pucks that I've been meaning to do the same with. let me know how yours turns out. friend of mine did it in his Scion XB and now the whole car rattles like a sunnabitch at low rpm from how stiff it is :/

Engine hoist would be the best way to do it, but you can jack under the bellhousing. Like Rx7chris said, don't put the jack on the oil pan, that will do some damage.

All you're really doing is taking the weight of the engine off the motor mounts, then remove the motor mount bar (whatever the technical name for it is, the piece that actually bolts to the front cover) and motor mounts as one piece, this will keep you from having the raise the engine up and risk cracking/damaging your exhaust etc.

I wouldn't mess around, do it proper and use a hoist, pick the motor up off the mounts and do what you gotta do, and like other said watch the shifter inside the interior so it doesn't smush anything

my pucks make the interior rattle pretty good. you sure you want to do this? ya engine does not move, launches are better, but for a dd it sucks. constantly tightening interior screws, and has caused a dash board rattle I need to chase down and fix. If it is a weekender then do it, if a dd just get new stock mounts and be happy. On a side note, add a 1/8 inch spacer under them for proper alignment of the engine......that is all.

Happy motoring

In a pinch, you can in fact jack the engine from under the oil pan; you just need a piece of 3/4" or better hardwood ply ( or other very rigid material) the size of the entire oil pan base, between the jack head and the pan. It spreads the pressure, reducing the PSI at any point.

Even if the engine and trans weighed (for example) 500 pounds, if you spread that load over 100 square inches of surface (which is just 10" by 10") you're only putting 5 PSI on any given point.

The picker is the better move, for sure. If jacking from under the trans bell, I'd still want to spread the load with a piece of wood. It's not too hard to poke a hole through sandcast aluminum if the pressure gets too focused, say by a jack with a very small head.
