You can just lower the back of the motor down 4-5 inches to change the rubber air seal that runs along the back edge above the muffler.

It would be a good idea to disconnect the 2 heater hoses going up to the diverter valves or they may get torn while getting pulled off as the motor lowers.
If the big 'S' hose going from the oil tank to the engine oil pump is old and dried out it would be good to buy a new one and change your oil and change that hose or it might split.

Support the motor in the center near the drain plug on a floor jack with a 2x4 or something on the pad to keep from scratching the aluminum case and remove the 2 large bolts motor mount bolts.
Then very slowly lower the motor down a little bit on to a cushioned jackstand under the case just behind the motor mount. Then you can replace the seal.

A better longer lasting and cheaper alternative if you don't mind the looks is buy some high temp 3/4" to 1" diameter high temp blue or black silicone hose and glue it to the back edge of the motor tin up against the chassis with high temp silicone gasket sealer while the motor is in place. If it's rusty there, sand off the rust first so the glue will stick.
If you don't use the high temp silicone it will burn up.

Thats what I did and it was alot cheaper than the origonal gasket and will never dry out or burn up from the muffler and turbo heat and you can't see it unless you stick your head in there looking for it.

I placed a bunch of hammers in there to weight the hose down and keep it in place while the silicone glue set up.
If you take the bumper off you can lower the motor about an inch or so while glueing in the hose ands it's easier to get the glue in there that way.
