timing case gasket

[Morton]

Hi all, it would appear the timing case gasket or seal has failed on my 02 GU 3L, has anyone replaced this before, is it an easy enough job?

Just use a couple of tubes of black mastik..
Thats what Moorooka A.......... did to mine and there was black mastik all through the timing case , god knows where it got to. I dont take my vehicle there anymore. Dodgy is being polite .

so no one on here has ever done one, I find that a bit hard to believe??
