  1. 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.

  3. 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
  4. 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
