Timing chain and oil pan gasket install

RTV should not be used on threads. Unless you like gunking all the threads up.
You should use a thread sealant like Permatex, which is designed for threads.
I gasgacinch the gaskets to the block,than use RTV on top of that.
Get a good engine building book, or even check out YouTube for a step by step run down on installing oil pans,timing covers,etc.
