    I drilled mine out as close as I dared then finished it off with a tiny cold chisel- bit brutal but worked (LS1)

    I used grease and the hydraulic method to get mine out of an LS3.
    Didn't notice any core plug??

    An oil plug in the end of the crankshaft?

    Hello again everyone.....

    Success - it came out using a £10 Ebay puller but I had to take the puller fingers off by grinding off the pins which hold them in so that the fingers could be inserted into the bearing one at a time. The force required bent the puller cross bar! Big relief though - I thought I was going to have to grind it out.

    I also considered using a rawl bolt - that was going to be my next move. Then the grinder if that failed.

    Some photos to show the puller etc. attached.

    Also a link to a web page that shows the oil plug.

    Thanks guys for your helpful suggestions.
