 DIY-20v valve seal replacement. step-by-step instructions Reply  Edit


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.

very nice! I have valve seal removing pliers built for me about 20 years ago.

You can install the new seal in a 20V just with hand pressure? It has been my experience 16V seals require gently taps with a hammer

thanks Dan, i was thinking i should have made something better than the single hook tool. the sealsy went in pretty easily, but i wanted pressure to be even all around the metal housing of the seal, so i figured why not turn down a tool quick at work.

nice, that looks like it would be 10x easier than what i did. the hook sounded like a good idea, til i started doing it and wished i had another 1 or 2 hooks.

I don't see the point of any special tools at all, I used some long/needle nose pliers to take them out and just my finger to push them back on. Has worked for a long time now.

the needle nose i have grabbed the valve stem before the seal. i didnt know how much room i would have for fingers since i never did them before. better to have everything covered than be stuck if you ask me. rather be prepared than wing it. thanks for the heads up tho...

Guys,

Here is another writeup I found, it was done some time ago, but it does show a great tool for doing the retainers. I haven't gotten one yet but next seal job I will for sure, it would have saved me HOURS doing my last seal replacement.

http://www.aeu86.org/index/eng...75407

Here is a link to the tool listed in the first picture

Seems worth the $40 to me!

Excellent write-up. FYI, http://www.toyotool.com/ makes a tool to make the removal and installation of valve springs, retainers, keepers, with one push. I worked with the owner to have one made that fits the smaller bucket openings in the 20v. It's very worth it.

O nice! I was wondering why they supported such a small valve stem.

I ended up buying the Lisle cheap version and turned the tool down with the help of a friend on a lathe to make it small enough.

im guessing the shims, especially compared to the 16v shims.

with the crank timing gear on its mark( its a small notch in the outer edge of the crank gear), lined up with the one on the oil pump case, that should put the number one piston, the one closest to the timing belt, at TDC, then the two cam timing gears should have two marks pointing at each other, like 3 o'clock for the intake and 9 o'clock for the exhaust also there are two marks at the 12 o'clock position for both gears that line up with marks on the back plate behind the cam gears, there is a 5th mark that you can see thru the oil filler cap, its a small indention, like a drill divet, in the intake cam that lines up with the edge of the baffle just under the filler cap.

hope this makes sense,
