One of the easiest jobs you will do.
No need to jack anything as the engine is bolted in anyway, just need a socket set and a spanner. Cant remember the sizes, but you'll find out.
There's a mount on top, on the left hand side of the engine block that attaches to the bulkhead. And one on the bottom of the engine, on the same side as the top.

I think. Not sure if thats the bottom ones, but has the top bushes.
And don't over tighten the bolt on the top of the engine, you're shafted. May be as well to get a new bolt for it. You can get a repair bracket if need be. But poly bushes snap bolts, that's the way I see it, and I'll never use them again.
