I'm going to have to take the engine out of my beetle one day, probably this winter or early spring. I have a valve continuing to stretch on the right side, possbly due to an induction problem.
Getting the engine unmounted doesn't seem to present to much difficulty. However, getting the car high enough to get the engine out from under it has worried me, until now. I did a search this evening for "remove beetle engine" just to see what was out there, and I found this page on geocities. It suggests jacking the right rear of the car up, taking the wheel off, and then sliding the engine sideways so the top of the engine goes through the space left by the wheel, which seems like a very sensible thing to do. So I expect I'll try this.
