k my 20v makes a collection of weird noises and i was wondering if neone can help me figure out wat that are..

1) noisy belt:

its not squeliing, just makes a lot of noise, specially when the engine is cold, i traced it to the alternator i think.

2) sometimes weird crunching noise after ignition

sometimes when car is cold, is makes a crunching noise after it has started, similar to that made when u turn the ignition when car is already running ( not that i ever do this)

3) my car sounds like a tractor.

the head, makes a real noisy tapping sound, cn hear it from in the cabin.

so ne ideas what these noises are and how to fix?

hey man
the grounchin could be the starter motor not diaingagin (cant spell sorry) not cummont out from the flywheel /// FIX get the starter motor checked out

the tappin could ither be the vvt cam trigger or ither the can where

yea my 20v also had a problem with cambelt idler made alot of noise, also i guess you could check the valve clearance could make the tapping noise. Sounds like your starter is not disengaging as above

the knocking will probably be the vvt pulley. not worth worrying about
as for the crunching.....

well i took it to my old work, and my old boss reckond the tapping was either tappets, or the shims, or the valve clearence, alougth he reckons toytas do that after a while, but we are changing my cam belt soon so i spose we can look then

by **Mr Revhead** » Tue Jun 22, 2004 3:48 pm

they dont have tappets!
cam works directly on to the shims.. could be valve clearance but that wouldnt start all of a sudden. (thats what the shims do... adjust clearence)
its very common for the pulley to start knocking

well that narrows it down, what in the vvt pully makes that noise?,

dammit i gotta check my clerances now

by **Mr Revhead** » Tue Jun 22, 2004 3:58 pm

they have fluid in them to dampen the knocking... it leaks...
doesnt affect the running at all.

by **strap-on** » Tue Jun 22, 2004 4:00 pm

will the knowcking come from the cam pulley? cos its not coming from that end, its definitaly underneath my rocker cover

by **Mr Revhead** » Tue Jun 22, 2004 4:02 pm

sound travels in funny ways in engines.... it could very well be to do with valve clearances... mine does it sounds like it comes from about 1/3 of the way along the head... its the pulley in mine

by **strap-on** » Tue Jun 22, 2004 4:20 pm

is there ne way to replenish that fluid?

by **Mr Revhead** » Tue Jun 22, 2004 4:25 pm

no its a sealed unit. for the price of the pulley just best to ignore it!
however u say you can hear it from inside the car.... if its the pulley you will probably only hear it at idle....

by **strap-on** » Tue Jun 22, 2004 4:40 pm

yup that sounds about rite, what is the price as a matter of interest?

lol im just trying to figure out why its useing oil, i just dont think it likes the shell helix, i might go back to the redline and see how that goes, have those oil filters come yet?

by **Mr Revhead** » Tue Jun 22, 2004 4:48 pm

just sorting out a deal on those pulleys now...

but prob around $400-500.....

filters should be here soon...... i hope

supply seems a little erattic at the moment....
ill be sure to let ya know!

by **Mr Revhead** » Tue Jun 22, 2004 4:55 pm

well bugger $400 how about $200 delivered?

by **strap-on** » Tue Jun 22, 2004 5:03 pm

whats the 200 for?

by **Mr Revhead** » Tue Jun 22, 2004 5:08 pm

the vvt pulley!!

i normally use castrol protec in mine, though i put helix plus in it on saturday as i forgot to buy some castrol before i drained the sump!

by **4ageman** » Tue Jun 22, 2004 11:04 pm

all 4age's make a knocking sound from the engine as they get higer km's on them its the wear in the gudgion pin. its nothing to worry about.
