korrupt66 Posted November 27, 2005 Share Posted November 27, 2005 I'm picking up a 91 Legacy for a song from a friend. The vaulves tap pretty bad. In the past I had a Loyale that was the same way. I posted on here for help and got lots of feedback for oil and filter combnations. I ended up replacing the oil pump, cam seal timing belt and micky mouse o-ring. I was wondering if anybody could give me a heads up on the Legacy. This is my first Legacy. Thanks for the help. 91 leg. fwd, 2.2, 205672 miles Link to comment Share on other sites More sharing options...
nipper Posted November 27, 2005 Share Posted November 27, 2005 probably the same advice as things dont change much. COuld need a valve adjustment, which i think is done with shims, i am not sure. nipper Link to comment Share on other sites More sharing options...

Gnuman Posted November 27, 2005 Share Posted November 27, 2005 probably the same advice as things dont change much. COuld need a valve adjustment, which i think is done with shims, i am not sure. nipper Not on a '91 EJ22. Those have Hydraulic Lash Adjusters, and do not need valve adjustments. If the valves are tapping that bad, check that the oil is of the correct viscosity (10W30 is good for winter, 10W40 for summer), and at at the correct level. If this does not fix it, and you have no oil leaks, it may be that one or more of the HLAs are sticking. clean them out with Carb Cleaner, and you should be good to go. Otherwise, you could just go ahead and replace all of them to be sure, but that is usually an unnessary expense. The engine that I opened up with a bad valve tap had one that was bad (O-ring gone) and a couple of sticking ones. I cleaned them all up (Immerse in a cup of carb cleaner, use a small drift punch to open the check valve, and work the lash adjuster several times, to get the cleaner all through it , then do the same in clean oil to "pre-fill" it, and replace it in the rocker arm. Do one at a time, and inspect each one for proper sealing of the check valve, and condition of the O-ring.) the engine will run very poorly for a few minutes until the oil pressure releases the check valve, and the HLA finds it's correct height. then all is well. Do not use a wire brush on these, and do not pull them out with pliers. If they stick, spray a bit of the carb cleaner on them to loosten up the gumming that is making them stick in the first place. you may pop them out gently with a small flat bladed screwdriver, if you are very carefull not to distort the metal you are prying under.

subie94 Posted November 28, 2005 Share Posted November 28, 2005 one thing that i've learned,always check your plugs to make sure they're not loose.for the longest time i thought my valves needed adjustment.turned out that i've been driving around with loose plugs.
