How To Install A 4 Piece Oil Pan Gasket

Should the oil pan be installed after setting the knob and installing the oil pump and feeder? Or is it better to bolt down the oil pan after the long block is fully assembled and the intake manifold is in place? There are schools of thought from both a logical and a convenience perspective that give credence to both processes. But the question is raised to raise awareness that the installation of an oil pan is not a simple matter and deserves attention at the right time. To that end, EngineLabs worked with Moroso to compile some helpful tips to ensure your engine’s vitals are safe. The focus will be on the wet tank system, but some tips may apply to the dry tank. Leaks are always present. And no one wants an oil leak, whether it messes up the garage floor or creates a hazard on the track. That really isn’t necessary nowadays. Advances in gasket materials and design, along with proper preparation and installation procedures, can all ensure a clean bottom. Do you have the right part number for your application? Have you changed anything on the framework that might interfere with the pan designed for your application? Does the oil pump feeder fit the pan properly? Then comes all the supports, such as the spacers, the air tray, and the mounting hardware. Plus, don’t forget that you need a dipstick and tube, even if your engine has an in-box unit or front chronograph cap.Check that clearanceOil pan manufacturers often have dedicated collectors for specific types of pans, especially for deep tanks or pans that move the tank away from the pump to the clear chassis parts. But it’s always a good idea to double check the oil filler clearance. . “When the pickup is too high in the oil pan, the pickup can suck in air when accelerating, cornering or braking hard.” floor. According to Moroso, GM products are usually about 1/4 inch in size while Ford products usually need to be 1/2 inch. There are two methods of checking the clearance from the drip tray: clay and ruler. First place a small ball of clay on top of the container, then fasten the pan down with the spacers and seals in place. Remove the pan and check the clay depth with a mechanic’s ruler or the depth probe on a dial caliper – the same way you would when checking the piston-to-valve clearance with clay. Another method is to use a straightedge and ruler to check the depth of the pan and the distance from the block to the bottom of the pickup. Make sure there is spacer on the pan or block when taking measurements. Then subtract the feed measurement from the depth of the tray. “If you are using a Moroso press-in extension oil pump intake manifold with your Moroso pan, you should attach the inlet to the oil pump housing,” suggests Schroeder. “This step eliminates the possibility of the air inlet escaping from the pump due to vibration.” Read more: How to Trick Duck TrainingMoroso recommends that the duct assembly and pump end plate be removed when high amounts of heat are applied to the pump. House.Gasket or sealant?Fed up with any reason for the gasket to leak, some engine builders took a cue from the OEM and put in a full RTV silicone bead (never use the tub caulk!) to seal. Seal all gaps between the pan and the block. Or did the OEMs pick up this trick from the racers? Either way, removing the gaskets with sealant keeps the oil inside the pan, but servicing the bottom end of the engine in the pit is a pain. Yes, sometimes there are too many good solutions. Gaskets have improved dramatically, especially with the introduction of composites and rubber, which pretty much eliminates the need for any kind of silicone treatment. They are certainly cleaner and easier to install than silicone and a gasket can be easier in surface preparation. On the plus side for RTV, it can work if you don’t have the right pads available. “Make sure to use OEM quality gaskets or equivalent. “Moroso offers a full range of 1-piece reusable silicone gaskets for most OEM applications,” said Schroeder. Moroso offers a new reusable oil pan gasket with steel inserts in the bolt holes to prevent the gasket from being over-tightened. Schroeder questions those issues,” Schroeder asked. And if the engine builder is using oil pans and multi-piece gaskets, nose picking is not a good habit. Our experience is that many leaks can directly stem from poor gasket quality,” says Schroeder. “We highly recommend replacing the multi-piece oil pan gaskets each time the oil pan is removed. This will ensure the integrity of the gasket. “Proper preparationBoth the block and the pan surface should be clean and straight. Be careful when removing stubborn old cushioning or RTV material. Do not gouge the rail surface of the block, especially on alloy blocks, when using a scraper or similar tool. Check all bolt holes as some may require a wire brush or even a hose. If the hardware is to be reused, clean the sealant or surface corrosion with a wire brush. Here’s another quick tip: count all your dowels before starting the installation. The same attention should be paid to the pan. Use a flat, solid surface to check for straightness, then clean the rails and bolt holes. If the pan is chrome plated, brush the threads of the drain hole to clear any remaining debris that may have started to leak. If the pan has trap doors inside, check their operation. In fact, some engine builders install these types of pans with the engine block in the upright position, just to make sure a door doesn’t get stuck in the open or closed position.Hardware and tighteningThe choice between bolts or rivet sets is generally a matter of convenience and budget, but there may be performance considerations in some applications. Schroeder said. “With studs, installers can get more accurate torque readings when tightening the oil pan to the block than when using bolts.” Place pan on studs or alignment tools if using bolts. Start all nuts or bolts and tighten fingers. If bolts are used, the pan may need to be shaken a bit so that the pan and gasket holes align with the stop holes. In the worst case scenario, especially with unbranded pans, you may have to remove a bolt to get the pan in place. . Some applications require different torque specifications for corner bolts. The usual tightening procedure requires tightening the four corners down to about 50% of torque. Then start tightening the center bolts to 50 percent and moving outward in an “X” toward the end. Repeat this process at 75 percent and finally 100 percent of the recommended torque. Some washers will loosen after initial tightening, so this procedure helps to ensure even pressure all around. Remember this is your last chance to inspect the crank assembly and install the oil pump. Position the pads and apply the silicone pads at the corners, as recommended. If using individual main washers and pan-ray washers, install the washers first, then position the washers and seal each junction with RTV.EpilogueIf using a multi-piece gasket set, focus more attention on the front and rear washers passing through the main covers. This is usually caused by improper washer installation and poor preparation on the front or rear radius washers, says Schroeder. “This can cause them to be sucked in. This will cause poor performance with cathode vacuum systems. “Another tip when using multi-piece gaskets and RTVs – use only a thin layer of film on top of the block and let it cure completely before mounting the pan. Failure to do so may cause the pad to slide and eject from between the pan and the block. Schroeder suggested by spraying/squirting soapy water on the outside of the oil pan and blowing air into the inside of the weld to see if the soapy water bubbles up.” “Another alternative is to fill the oil pan with water and check for leaks. Be careful how much heat is transferred to the oil during soldering, as you don’t want to warp the oil pan’s mounting rods. “Also, instead of hammering the pan if the septic tank wasn’t, Moroso suggested taking pictures of the important areas and calling the technical department. They may recommend returning the pan for modification. Savvy engine builders do it as the last step. Who wants to pull the pan because a washing machine got lost or the valve cover bolt fell into the crankcase?
