Once the RTV is applied to all the mating surfaces, you want to carefully locate the new oil pan relative to the engine block and exposed rear of the timing cover. Tipping the front of the new oil pan down like this enables more positive engagement of the front of the pan with the read of the timing cover. Once contact is made, rotate the new oil pan down to engage the locator pins in the block. Then proceed to hand install and start all of the oil pan blocks.
