maybe its a wrist pin you hear..once it warms up it gets tight...did you adj your valves with the engine a little warm?did you double check them after you ran it..

The big question is what don't rattle in a 22r..

They have to rattle,,that how you tell if its rnning or not..

Makohon · « **Reply #4 on:** Mar 08, 2005, 08:16:49 AM »

i dont remember if the engine was warm at all but no i did not double check them after i tightend them... the engine is new/rebuilt.... sooo....

Makohon · « **Reply #5 on:** Mar 09, 2005, 06:27:30 PM »

when the truck is warm ''after 30 min drive'' and start back up again 30 seconds after it is off... the valves still are clapping!! help!!

Do you have an oil pressure gauge? I don't know if toyota has hydrolic lifters , but your oil pickup could be getting plugged.

Makohon · « **Reply #7 on:** Mar 09, 2005, 07:35:56 PM »

naa i dont have a gage... but if it was plugged then why would it quiet down after a few mins?? thats what i thought it might be but then i was wondering if it were plugged then wouldnt it always be clapping??

I don't know Toyota engines that well, but I know they have a lot of trouble with timing chain guides from what I have heard. Also if the rockers have a ball socket under the adjustment like Nissan then they could be worn and have a ridge that will make adjusting them impossible because it rides up on the ridge and gets tight or down on the worn part and is loose. I am sure there is a good answer for you, I just don't have one beeing I have only worked on a couple Toyota motors.

Well you should always do the ajust thing warm, what did you set them to? intake and exhoust?

tanman2003 · « **Reply #10 on:** Mar 09, 2005, 09:55:42 PM »

just so em .001 tighter than warm, so you can do it cold. .007 and .011 intake and exhaust.

you may need new adjusters, the tips are worn unevenly.

then again maybe you valve cover is on too tight. that distorts the rocker shafts and could make a tapping noise.

no that definitely sounds like timing chain, im willing to bet on it, toys are known 4 this

I will have to agree..the more he posts the more it sound like a bad chain tensioner or broken guide..

Makhon,,you said the motor was a recent rebuild?Do you have any idea the brand or mfg of the timing set and guides?
Pop off the valve cover,,see the guide,,is it missing?do you know what I'm talking about?
You should be able to look down in there with a flash light..chances are if the tensioner is bad it caused the chain to get loose,,in turn allowing the chain to slap and bust the guide..while the valve cover is off and the motor a little warm re check your valves..

ill try and check all that stuff today!! i have no idea what company ect.... but why would it only do it for the first minute of so then stop!!

derek · « **Reply #14 on:** Mar 10, 2005, 12:26:51 PM »

when you first fire it up there is no oil pressure.
when oil pressure builds the tensioner tightens the chain causing the rattle to stop.
really worn out chains will rattle all the time.

I put new chains gears and guides in mine and it stil does it if it is real cold outside

derek · « **Reply #16 on:** Mar 10, 2005, 01:28:31 PM »

what type of filter you using?
also if its real cold out the oil is thicker, takes longer to get circulating.
when i used to worry about it

i would run a thinner oil in the winter.

toyota filter

Makohon · « **Reply #18 on:** Mar 10, 2005, 02:14:03 PM »

hmmm that makes sense... i have no idea what kinda filter... but it has a new chain on it...''rebuilt motor'' hmmmm could the filter be possibly clogged a lil bit so thats why it would take longer for the oil to get circulating??

its a fram!!!

derek · « **Reply #20 on:** Mar 10, 2005, 02:49:35 PM »

fram filters allow the oil to drain back into the pan.
so when you start it up it is dry and takes longer to build pressure.
i think the upper end frams (double guard) are better, but overall frams are crap.

a toyota filter does too if i let mine sit up for a whole day before I change my oil I can take it off without getting any on me cuz it is empty

derek · « **Reply #22 on:** Mar 10, 2005, 03:53:31 PM »

toyota filters are supposed to have the anti drain back valve in them.
wonder if they have changed their design?

my autoshop teacher said if your truck makes noise like that when you start it you need to turn up the radio for a second to drown it out. He said it just takes a second for the oil to get up into the valvetrain--more noticable with hydraulic valve trains. But on your firebreathing solid cam set up, it is also normal to take a second for the oil to get up top. Don't rev your engine to make it happen faster--that just grinds stuff together more. Stick a long screwdriver onto the valve cover to see which valves are making the most noise and put the other end to your ear--redneck stethoscope. You can also see if your timing chain is making noise this way too--just don't wear a tie when you do it :

Umm, oh yeah, lest your forget: A tappy motor is a happy motor.

This is still my favorite icon.
cheers

there only about half full of paper..Cut one open and look at how much paper is in it compared to a napa gold filter..
I think the napa gold filters are the best by far..I notice a huge differance in how claen my oil stays over time over any other filter..In my toyota powered sandrail i can go a weekend with my oil just starting to get dirty..With anyother filter I have used its flat out dirty before the weekend is over..In my ctd tow rig I get about an extra 1500 miles out of my oil with the napa filter over other brands..

go to the amsoil website and order an amsoil filter. its twice the size of stock, and apparently filters really well. Probably cant go wrong with the yota filter eiether. But I do know larger is better with filters, and you ALWAYS get what you pay for with toyota parts. I will try to dig up the part number, they changed there site and its sort of hard to navigate. Wish I could help with the noise, does sound like timing chain if it quiets down eventually. I have a reman motor and I was able to get the valves to quiet down somewhat, however they still tick away which is ok with me, the motor was 500 bucks.

kneedownnate · « **Reply #29 on:** Mar 11, 2005, 08:37:52 PM »

Everybody I know that knows squat about cars says don't use fram, they're cheap and don't work well. My brother will only run toyota filters and I would kinda agree, but I usually use whatever I can find, but have gotten on this kick of using hastings filters lately. The one I got for my 91 is nearly twice the size of the fram.
