How do i get to the RODS/Pistons in the Block?

How do i get to the RODS/Pistons in the Block? do i take out the oil pan and what will i encounter while removing the oil pan?

Not to sound like an a$$ or anything, but if you have to ask this question, it’s probably best that you pay someone to do it for you. But if you are still bound and determined to do it yourself, you have to pull the head, use a piston ring compressor to compress the piston rings, and tap the pistons down into the cylinders being very careful that the rods don’t touch (score) the cylinder walls. Make sure the arrow on the pistons are facing the timing belt and that the IN marks are towards the firewall. Once the piston is close to the crank…make sure the rods don’t score the rod journals on the crank. All of this should be done to a properly honed block. This is not a task for the novice mechanic. Best of luck.
