adjusted valves, now its louder?
« on: Oct 09, 2007, 10:51:02 AM »
i adjusted my valves a while back on my 22re.  i did it while the engine was cold, so i went a little loose with them.  it made alot of valve train noise, so finally i got around to adjusting yesterday with the motor warm so i could set it where it needs to be(.008-intake,.012-exhaust).  i put everything back together, fired it up, and it ran really smooth and quiet.  after it warmed back up again though, it started getting some loud rattling sound, almost like a bad tensioner or timing chain or something.  i pulled it back apart, checked everthing, and its all into spec.  fired it back up, and it does the same thing.  when i rev it up and let the rpms drop, it goes away for a few seconds, then comes back again.  i replaced the timing chain, tensioner, guides, and gears maybe 6-7k ago.  any ideas?  it never did this before i adjusted the valves.

adjust the  exhaust to .010  and intake to .007    you dont get them as warm  when you are adjusting them  as they get at operating temps

i had to replace the adjusting screws on one engine. the area that comes in contact with the valve was shattered. made it almost impossible to adjust.  and the engine would rattle like a diesel. changed them and the rattle went away.

I'm having the same problems. I adjusted them to .008 and .012 and then it got louder. Then I tried loosening the valve cover. That didn't fix it. So I re-adjusted them to .007 and .010 and It got even worse, I have no clue why that would be.  Any Suggestions?

Both of you need to check the adjusting screws as stated above. If they are worn out you will never get a true adjustment.

ive found  good ones at the  pick n pull but  only in wrecks,

new  oem  would be best

i also question your tensioner,  where did you get it??   it  sounds  like its only  "tensioning"  when you  get  above idle  which is BAD

What valves are you guys having problems with?  I have had problems with the number 2 and 3 intake valves because the plastic spacer was worn down to the point that the adjsters were touching less than half of the valve stem.  I know you can also get adjusters from LCE or engnbldr.
Trust in the LORD with all your heart and lean not on your own understanding, in all your ways acknowledge him and he will make your paths straight.  Proverbs 3:5-6  Don't let anyone look down on you because you are young, but set an example for the believers in speech, in life, in love and in purity.  1 Timothy 4:12

mine ended up being the valve cover gasket.  it was squashed down too far, and even if i loosened it up, still too far.  got a new one, and the problem is gone.

They will have a groove worn in them. If it were mine I would source new ones.

wow! thats a lot louder than mine was.  i had it sound like that once after i changed my timing chain.  ended up the sound was coming from a bolt that i installed in the oil pump wasn't the right bolt for the hole. was hiting the links on the chain and sounded just like that.  if you have taken the timing chain cover apart, look into it, that might be the sound your hearing.  keep posted.

I had good luck talking with the tech guys at MC and ToyConnection. Both had relevant points in problems that I have had in the past. Seems like they are eager as we are in trying to get our rigs up and running.

i might have to give either marlin or toy connection a call tomorrow. im pretty sure i got the oil pump bolts right this second go around. that video was from my first attempt at the timing stuff. ill get another video tonight. it doesnt sound like the chain rubbing on anything anymore which is very good.

you might need to find a 22RE valve cover  they are slightly taller, thats what i have on my engine,  the regular 22R cover hit the rockers

i might try unbolting it and raising it while running to see if it goes away. i tried running it without it on once to find a sound. wont ever do that again! freakin dual row chain flings some oil thats for sure.

got a RE valve cover and some good looking adjuster screws while i was in there. one question though, how do you have your throttle cable hooked up? i see you have a weber which probably makes a difference

my 79's cable is attached to the passenger side rear valve cover stud



earlier in this thread someone posted about a plastic spacer on the rocker assembly,  in this case go find a 20R at the wrecking yard and get the entire rocker assembly and get the spacers, rods, whatever you need from them

hotrod,  you will need to cut part of the tin splash guard (keeps the oil from slinging out if you remove the oil fill cap) out of the valve cover mine hit my timing chain till i fixed that

ya, i got the throttle figured out and then threw it on and it started making a weird timing chain sounding noise, so i pulled it back off and it was gettin into that splash guard as you were saying. so put the 22r cover back on for now. i dont think its tapping, its pretty loose though. ill proabably clean up and paint the 22re cover and cut out that splash guard and run it.

about that plastic spacer, where is it? im running the complete 22r rocker assembly, dont think i missed anything unless something changed between the 20r and 22r heads?

dang, well i just sent engnbldr an email, hopefully his cam is supposed to be .006 and .009 like yours and thatll quiet them down alittle. people think its a diesel right now.

edit: ted recommended .007 intake and .009 exhaust
       gonna go try that out and see what happens!

just put them to .007 and .009 and they quieted down a ton. still not completely silent but alot better than it was. its about the same as it was with stock motor. might drop them down to .006 and .008 when i put on the new valve cover but i dont want to burn up a valve on a brand new motor, or any motor for that matter.
