How to Replace an Oil Pan Gasket with RTV
- 1). Clean the gasket-mating surface of the engine and the oil pan by scraping the old gasket debris off. Spray the area with carburetor cleaner and wipe it clean with a rag, making sure no oil residue or gasket material is left.
- 2). Line a 1/8-inch bead of RTV around the surface of the sides of the oil pan, working your way around the bolt holes. If the vehicle is a rear-wheel drive, use a 1/4-inch bead on the dips for the crankshaft on the ends of the oil pan.
- 3). Allow the RTV to "skin-up." This means that when you touch it, it does not stick to your finger because it formed a skin as it was drying. Depending on the amount of humidity in the air, it could take as little as five minutes or as long as 20 minutes to skin-up.
- 4). Put one oil pan bolt through one of the bolt holes in the oil pan. Grab at least two more bolts. Carefully match the oil pan up to the block, but do not let it touch it yet. Screw the bolt you put through the bolt hole into the block for three threads. Put two more bolts in the oil pan at the opposite end of the pan and thread them for three threads. You can now let go of the oil pan and it should stay balanced.
- 5). Insert the rest of the bolts, starting them by hand. Run them up into the block with a socket, tightening them snugly. Make sure you don't overtighten them by cranking on them, or you will wreck the RTV gasket.
