    Second day on the road after replacing the rear main oil seal and still no
    leaks! :-) (yes, I remembered to put oil back in...)

    One problem has cropped up though... I replaced the manifold to head
    gasket (old SII style one piece unit), most of the manifold bolt / studs,
    and the carb packing block and bottom gaskets. Now I have what sounds like
    a vacuum leak. Once warmed up, a whistling starts. The Land Rover sounds
    just like a tea kettle. It only whistles with high vacuum i.e. when gearing
    down and when idling. It's quite loud, I get funny looks from other people
    at intersections.

    Any suggestions on how to track this leak down? I've tried spraying carb
    cleaner on the joints with no luck..
