We're taking the engine out of this beetle. We were able to remove okay 3 - 17mm nuts holding the engine on. We took the nuts from the 2 bottom bolts and the upper right(passenger side) bolt. Our problem is the top left (driver side) bolt. On the back side the bolt is not fastened by a hex nut like the other three. It looks like a round threaded casting on the casing but not a nut that is removable. As far as the bolt is concerned, there is a "knob" that looks like it was casted to keep the bolt from turning. So....you can't turn the bolt because of the "lock" and there is no nut to take off.
For the life of me I can't figure out how they got this engine in, not to mention...How can you get this out to complete engine removal
Anyone ever seen this? Have an suggestions.
Thanks
