Anthony- have you thought of buying, (and damn, can't recall the company name) it looks like a drive up hydraulic jack but, it's mechanical. I'll see if I can find the product and be back. It's been talked about here many times.
Ok, here's a link. I'm thinking about buying one myself. Can't change a engine but, It would make life easier for servicing, cleaning ect. They also have attachments for other duties.
