  1. Instead of cluttering a useful thread, I thought I would make another for a bit of information on these, http://puu.sh/bKmHR.jpg http://puu.sh/bKmJ3.jpg http://puu.sh/bKmIs.jpg http://puu.sh/bKmJQ.jpg Hydraulic lift suspension that sits on top of springs/shocks Both of the 1984 Leones I have (Wagon that I drive and spare sedan parts car) Have these on them. Note the really low spring perch mount, (Shock Subaru#21007GA280 made by SHOWA #90801) I presume the second # is SHOWA The pump sits in the left front guard http://puu.sh/bLIBV/af686db895.jpg Then seen through bumper http://puu.sh/bLIAX/b0b46e54ee.jpg Has a filler that bolts above and to left of radiator http://puu.sh/bLIBp/5ada10ac91.jpg Bolt on filler has a small air bleed hole in it. One line comes out of pump from here http://puu.sh/bLIzc/9f19657560.jpg Which runs to front left strut and splits off. So, if anyone has more information on these that would be cool, or questions that I might (not likely) be able to answer. No obvious marks on pump unit but i haven't had time to clean it down yet, so there may be. Cheers, Tom
  2. 3-43 7. Hydraulic Valve Lifter 1. Replacement The hydraulic valve lifter can be replaced even when the engine is mounted on the vehicle as follows: 1. Disconnect both the blow-by and PCV hoses 2. Revove the valve rocker cover. 3. Using the special tool (Socket Wrench: 899988607), loosen the valve rocker ASSY and remove the push rod. 4. Raise the vehicle body with a jack and suppor it on a safety stand. 5. Remove the nuts which secure the front engine mounting and slightly raise the engine using a floor crane. 6. Remove the drain plug to drain the engine oil completely. Detach the oil pan. 7. Remove the hydraulic valve lifter. Use of a magnet facilitates removal. http://www.ultimatesubaru.org/forum/gallery/image/3767-ea81fig-3-45-a-5678/ Fig. 3-45 A5-678 8. The valve lifter can be installed in reverse order. 2. Adjustment 1. Perform adjustment in cold condition [coolant temperature 20 to 40 deg. C (68 deg. to 104 deg. F)]. 2. Retighten cylinder head nuts and bolts previously if necessary. 3. Adjust hydraulic valve lifter with the following procedures: a. Perform adjustment in two (2) sequences. Sequence (I) -------------------- Position #1 cylinder at TDC (compression), and adjust the valve lifters for intake and exhaust valves on #1 cylinder, for exhaust valve on #3 cylinder and for intake valve on #4 cylinder. Sequence (II)---------------- Position #2 cylinder at TDC (compression), and adjust all the others, i.e. for intake and exhaust valves on #2 cylinder, for intake valve on #3 cylinder and for exhaust valve on #4 cylinder. b. Raise up the bend of lock washer, loosen the lock nut, and then turn the valve rocker screw clockwise by approx. four (4) turns using Valve Clearance Adjuster 498767000. http://www.ultimatesubaru.org/forum/gallery/image/3768-ea81fig-3-46-a5-700/ Fig. 3-46 A-700 <Valve opens. Screw by approx 4 turns> c. Leave it with the valves opened for approx. 15 minutes. http://www.ultimatesubaru.org/forum/gallery/image/3769-ea81fig-3-47-a5-701/ Fig 3-47 A-701 <Leave for approx 15 minutes then pressure chamber volume becomes minimum. Valve moves to close a little.> d. Unscrew the valve rocker screw gradually. Then, the rocker arm stops moving due to the closing of valve. This condion is called "Zero Point". http://www.ultimatesubaru.org/forum/gallery/image/3770-ea81fig-3-48-a5-702/ Fig. 3-48 A5-702 <Valve closes Zero point Unscrew gradually> e. Moreover, unscrew the valve rocker screw counterclockwise by 1.5 turns http://www.ultimatesubaru.org/forum/gallery/image/3771-ea81fig-3-49-a5-703/ Fig. 3-49 <Hydralic valve lifter adjusted Unscrew by 1.5 turns> f. Tighen lock nut, and bend the lock washer.
  3. trying to eliminate my TOD (tick of death) or lifter tick and looking into maybe just making some adjustments along w/ using a heavier weight oil along with an oil treatment, but not sure i can make those changes if the rocker-arms are hydraulic. it would seem that based on the relative simplicity of the Loyale's engine, they'd be solid, but not sure. anyone got a firm answer for me? thanks much, Glen
