Like the title states, is this gasket still available. Can it be had by itself? Is silicone a suitable replacement for the gasket?

I was swaping to my electronic dist today and the gasket didn't remain in one piece.

You don't want to use silicone. Because if you had to adjust the timing it would be stuck. New gaskets are available, either through your local dealer, parts store, Victoria British, MSA or you could make your own.

I don't believe the bottom part moves. It's the fixed base that screws into the timing chain case.

Either way i'll wait to get the gaskets. I didn't know if they were available from local parts stores, that'll work. Hope they have them in stock tomorrow.

Thanks

You're right the bottom part (where the gasket goes) does not move. Silicone will work, but use only a thin coat. You don't want any bits of it to get squished out and circulate through the oil system where they might plug up an oil passage. The gaskets (Nissan OEM) were available last summer. They were very cheap, so I bought spares of that one and the oil pump to timing cover gasket to keep on hand for my next project. If you plan on keeping the car for a long time, stocking up like this is a good idea IMO, as it can save time and shipping costs. Especially if you prefer OEM gaskets like I do.

I have been making my own gaskets for smaller parts like thermostat, thermostat housing, etc. Also for lawnmower, et al. I use plastic from toy boxes ( the clear window part) so you can trace the outline with a sharpie, then cut out the shape & trim. Then trace on the appropriate gasket paper and cut out.
