LS 1-6 Install Instructions

We recommend using the Stock (or equivalent) pan gasket, with a light film of silicone for sealant. The stock bolts may also be used.

Dry Sump Pan #1005, #1005M


On Stage I systems, where the stock internal pump is still used for pressure, the special red fitting #6400, with special lip seals is used to form a suction tight seal between the pump and the oil pan, as the supply of oil from the bottom of the dry sump oil tank to the pressure pump.
NOTE: We make two versions of this design, STD and DRC, which is for “Dual Row Chain” usage. If you are using a Dual Row Chain, there are 3mm (.118) spacers, which move the stock pump forward. These pans are identified by “DRC” stamped on pan rail by front inlet. Only Oil Pans with “DRC” (special order) can be used with Dual Row Chain & Pump Spacers.

Windage Tray


We DO NOT recommend using the stock “factory” windage tray. The Aluminum tray & wiper, in you’re A.R.E. Dry Sump Pan is specially designed to work without the steel stock tray. Back-to-Back Dyno tests have shown as much as 8HP LOSS by using both trays.
NOTE: On “Ultra Shallow” #1009 version, the tray mounting extensions on the main cap bolts may also need to be ground off.
-The windage trays are secured to the pan with 10-32 stainless steel screws (1/8” allen) and special wave washers. We assemble the screws with motor oil only. We DO NOT recommend Loctite.
-The A.N. fittings in all ARE Oil Pans are “O” ring seal type. We recommend using motor oil and/or anti seize for sealant. Silicone sealant may also be used if necessary. “O” rings should be replaced occasionally, as needed.
-The scavenge fittings are fitted with stainless steel scavenge filters, integral in the fittings. These should be removed after 1st run, and periodically to check for debris. These also are a good indicator of bearing condition etc.

Plumbing


We recommend using –12 scavenge lines on Stage I systems. (#3120, 3 Stage scavenge use 1 –10 scavenge line from center pick-up in pan to front section of pump. Use –10 pressure lines to filter and back.) Important Scavenge lines should always be as short as possible. Also, avoid lines from forming a “toilet trap” effect by going up higher than the pump, then back down. Keep lines flowing upwardly to pump inlets. In Stage II & III systems using 3 scavenge stages, we use -10 scavenge lines and either –10 or –12 pressure inlet. Supply lines from tank bottom and scavenge return are always –12 (occasionally –16)

Initial Start Up


Prior to running engine for the 1st time, squirt some motor oil down the pump fittings to prime pump. Add 1-2 quarts to the engine itself, and fill the Dry Sump Tank at least ½ full. The supply line to the pressure pump should be loosened until a flow of oil is available at the pump. Check tightness of all lines.

Tank Level


Add oil until the oil level is just AT (NOT ABOVE) the level of the internal deaerater.
