This is Pineapple Racing’s exclusive Heavy Duty Water Seal kit. Pineapple Racing tested these seals for over 7 years in numerous street and track cars before offering them to our customers. They have proven to be a significant upgrade over the stock water seals. Pineapple Racing use them in all their 5-year warranty motors.
Also, these seals are re-usable if you need to reopen the motor to freshen it, as long as the mileage is not too high or the engine too overheated. In other words, if you make a mistake and blow up your engine or perhaps improperly clearance the seals or whatever, these seals can be removed, allowed to “rest” for about 30 minutes and be reused when you put the engine back together. Stock water seals must be disposed of when freshening an engine, even with just a couple heat cycles.

Kit includes

• Water jacket o-rings
• Front cover o-ring (and backup washer, if needed application dependent)
• Dowel o-rings
• Rear stationary gear o-ring
• Oil pedestal o-rings or Gasket (depending on application).
• Oil Metering Pump “O” Ring
• Dowty Washer Set (Tension Bolt Washers)

Please note this kit will fit 12a and 13b engines build between 1974 and 1984

Pineapple Racing Solid Dowel Pins

• Helps prevent cracking the plates from hp loads or “ping” (esp. important in the 20B and Series 5 & earlier turbo engines)
• Spreads the load across the length of the engine.
• Helps to insure a true engine centerline which reduces engine failure and increasing bearing life
• Using an external oil line provides a more even oil pressure to the main bearings
• Low cost, easy installation
• Available for: 12A, 13B and 20B (12a and 20b Special Order)
• Custom lengths available (Special Order)

Pineapple Racing Solid Dowel Pins provide an easy, cost effective aid to hp and “ping” loads causing plate cracking or engine damage from loss of clearance from engine flex. Our super strong proprietary material has been meticulously machined to provide what we feel are the most accurate and consistently machined solid dowel pins on the market. The O.D. is accurate to 50 millionth’s! That’s 0.00005”. We “lightly” tapped one end for use with a Dowel Pin Puller.

Replace just the lower dowel pins helps to insure your engine’s centerline remains true. It is a great update requiring no machining.

Replace both lower and upper dowel pins for the maximum improvement. Replacing the upper dowel pins requires the installation of an external oil feed line to the front main oil galley to replace the OEM galley in the OEM dowel pins. Our Oil Pedestal Adapter kit makes this a simple job that can be done with simple hand tools and an electric drill.

High horsepower and the shock loads from “ping” put a tremendous load against the rotor housings. The load deflects the rotor housings outwards, pushing the dowel pin with them. The dowel pins are retained by their fit into the cast iron plates. If the loads are too high, the upper dowel pin can cause the plate(s) to crack. Additionally, since the upper dowel pins are also used as an oil galley, a massive oil leak is also possible. The OEM 20B is especially prone to this type of damage,  and with the price of the “thick” center plate near $1800us, preventing this type of damage pays for itself.

The Pineapple Racing Oil Pedestal Adapter is a stylish, Nickel plated rotor shaped adapter. It easily installs between the existing oil filter pedestal and the rear plate. It features a ¼”NPT port for an external oil line and an 1/8” NPT port for oil pressure or oil temperature.
