Valves Ticking?

[KHSFilipino7290]

there is a small ticking sound coming from my motor i am pretty sure its the valve springs or something to do with the that area... is this a major problem that i should worry about or should i just try and baby the motor from now on?

[timothyc1984]

that sounds like valves and uh you might want to fix that 'cause that can lead to much worse things. and even though its fun (i know) running any motor hard will eventually wear it out faster then babying/moderate. oil changes are even moreso important. HAVE to remember to keep everything in there lubricated.

Thats why my engine has an oil pump

valve adjustment probably...

The 1ZZ-FE engine is already a little loud to begin with, unless you notice a huge drop in performance or drivability then I would not worry about it too much

Thanks guys i just needed to know

[94_Rolla_Guy]

if your really concerned take the valve cover off an measure your valve clearance's most likely the valves are out of clearance

[KHSFilipino7290]

if they are how would i correct a clearance problem? i've been reluctant to mess with the vvt

[punter]

VVT is unrelated, clearance is between the cam and valvetrain.

Assuming 1ZZ?
Are they a shim over bucket?

I would not mess with it, unless the valves are bad.... If they are very loud.... or the engine misses because of bad valves..

do they sound like sewing machines? or just a slight tapping with the engine is cold? Also if the engine has high mileage, don't just have the valves reone, or it could burn oil, because of a mismatch between worn rings and new valves....


Don't try to adjust them if you have no experience and you could set the clearance and lash too tight...

too loose is better than too tight..


Good luck..

1zz has shim under bucket iirc

because of a mismatch between worn rings and new valves

pistonrings and valves have nothing incommon...


too loose is better than too tight..
yea, too tight and valves dont close up and burn

sure they do, if you have lots of wear on rings and worn valves,,, then if you repair the valves, it will pump the oil past the rings at a furious rate (or at least more oil). That's why it's usually not a good idea to do only a valve job if the rings have lots of wear..... Somtimes you can get away with just doing valves, just depends on the wear...

yes, I know he was talking about excessive tapping of the tappets...
I just expanded on going further..

No it wont, piston rings wont do shit to the valves. period.

sorry, you still didn't understand... if an engine has both wear on rings and valves. and they both leak... or allow leakage of oil and gasses... it is not a good idea to do only a valve job.. and not do the rings.... as that will cause substanial oil pumping past the rings,, as the rings would be a very weak spot in the seal of the combustion chamber...




If you don't believe me, fine...

just gotta stop this here because I went beyond just his tapping noise, into more work..

[punter]

If it's shim under bucket it's unlikely to be valve noise, unless it's done stupidly high miles or had the head fiddled with.

Sure it's coming from the head?

Could be ticking injectors, its common form them to be loud on 4ages

So true.. tick tick tick.. almost like a pinging sound.
