this is done on a silvertop 20v. generally, the steps are very similar, just some things change. please refer to your fsm if its a different motor. i can say that the 16v is very similar, just the cam gears dont have the center marks to line up against each other, and the bolt loosening/tightening sequence might be different, i didnt check.
THIS IS A GENERAL, STEP-BY-STEP GUIDE ON HOW TO CHANGE YOUR SEALS
-gather all needed tools for the job. you dont want to be searching once you start.
-start with unbolting the negative terminal on your battery.
-next, remove the cam gear covers(top and middle) and the spark plug cover.
-remove spark plug wires and loosen plugs.
-heres the seals i used. 2 sets from an '03 toyota echo made by Fel-Pro. $54 each at pepboys, i got to love the discount i got, $20 each!
-how to properly line up the 20v cam gears and crank before removing anything.
-removal of the cam caps.
-then remove the cams. you dont need to remove the dist to get the exhaust side out, dont bother, you wont have to set the timing again then.
-removing shims and lifters/buckets.
-now, if you have the head on the motor, you need to keep the valves from dropping into the cylinder when you remove the retainers. i took a compression tester, removed the gauge and fitted a hose coupling, and removed the shrader valve from the other end. screw the compression tester into where the spark plug goes(after removing plug), and connect to compressor. 90psi seemed to be plenty to keep the valves up. some people use rope, and feed it thru the plug hole into the cylinder, or if the head is off, use the SST C-clamp.
heres the compression tester and the piece to connect to the compressor
heres the tool done, just remove the Shrader valve where the tweezers are pointing to.
-removing the retainers. be careful, they are easily lost.
-remove your old, leaking valve seals.
-everything apart and neatly organized.
-why not check if you can?
-the tool i made to put the valve seals in. this worked great! looks like a shell casing...
-installing the seal.
-then put the spring and top hat back in. followed by the retainers. i found that it you dipped the little retainers into some fresh oil, then tried, they would stick to the valves. this step is super frustrating the first few you do, it gets easier after about 18...
-re-installing the cams, then the cam caps. do this properly, as per FSM. try to keep the notches/marks lined up so you dont have to turn the cams once bolted down.
-install the new valve cover. best to replace the gaskets now too. dont want to be leaking oil afterwards.
-line up the cam gears wiht crank, and put the timing belt back on.
-put all covers and what not back and start her up. if you didnt remove the dist, timing should be fine.
