Does anyone use any gasket sealant on it? Or just put it on plain?

Thanks. I've gotten to know the bottom of the 240 pretty well the last 2 days. lol

 

I used a very thin coating of RTV on it. Make sure that you get all of the old gasket material off. Also, the new gasket will be a little long at the bottom. Make sure that it is trimmed properly. Too long or too short and you will weep oil at the joint where it meets the oil pan.
