Removing "RTV" from oil pan gasket
Is there some way of removing gasket maker from silicone gaskets? I'd like to re-use my oil pan gasket since it's basically brand new but I have all the snot from the last install on the gasket.

Elbow Grease should do it. You can try lacquer thinner and see if it will loosen the bond between the gasket and the RTV. Watch to see if the gasket is being attacked by the solvent. I do not know any way to avoid scraping, except for buying a new gasket.

I'll give it a shot but I have yet to find anything that'll remove "gasket making crap" from anything besides scraping or an abrasive wheel of some sort.

Re: Removing "RTV" from oil pan gasket
Apparently the gasket is silicone/rubber. Sticks very well.
I ended up buying a new Fel-Pro gasket. It says to install dry.
The GM service manual states to install the gasket with "RTV" at the corners on the timing cover and RMS.
I'll install this one dry. Hopefully I don't get a leak at the front cover as it's aftermarket chromed cast aluminum. That's much thicker than the stock stamped steel one.

Wait a minute I wasn't even thinking pan gaskets go on dry anyway, but do put that bit on the rear main and timing cover otherwise it will leak like a sieve make sure that chrome seals RTV+Chrome=Leak 9 times out of ten.

Re: Removing "RTV" from oil pan gasket
Well I installed it dry per your suggestions and Fel-Pro's suggestion. 4 ounces of oil (leftover from soaking the lifters) and the pan is leaking at the timing cover corner. At least I haven't filled it yet.
I guess i'll be dropping the pan and gooing the corners.
