i was in a wreck over christmas break and had to fix my 1996 4runner, put 2 grand back into it and lately i hvae heard some noises comming form the engine bay GREAT!!!

i can really hear it when the engine is warmed up and sitting at a stop at 600 rpm its a ticking sound, but when i slowley acc. it gets faster and higher pitched, kinda hard to hear over my CAI,

so my question is do i hvae too much carbon buildup in my 202,***mile engine, or is it a belt or timeing chain?

i am also wondering if i stop using the usual 87 octane and put in some 89 or even 91, will it hurt my engine?

what about fuel addatives? BBK? just let me know what might be wrong?????

thanks guys!

Personally I do not see a problem with throwing some 91 in it. I do that to my 99 with 170, *** miles on it and I never have a problem. Now my wife had a 03 Audi TT and if you put anything less than 91 it would shut down. As for the ticking noise, maybe someone else can help you with that. I am not mechanically inclined.

when i had my 96 i would run nothing but 91 and ran great. and my 2002 i run ATLEAST 89. every now and again ill get 91 or higher. never had a problem with it. and my moms 05 runs atleast 89 and every no and again runs 91 or higher, not a problem in any of the three.
 
thats great! i sucked it up and put in 91 lastnight, 307 a gal. well good thing im not paying for it!

well lets see how 91 goes with this old 202*** mile truck

I have heard it has a higher solvent property because there is more ethanol in it. But I have no idea how true this is. I have never heard any extreme warnings against it.
 
i also hear it has a bit more addatives, and something (cant remember) but it keeps the gas from blowing up b4 the spark plug sparks, (which causes carbon build up) so more fuel+better power?

but i also hear 91 is for higher combustion cars, high preformance, will i have any problems with it hurting my head gasget?

Premium actually has less energy per gallon then regular. Don't be fooled!!! All it does is prevent knock at higher compression ratios by lowering the auto-combustion point. I think performance vehicles are typically 13/1 pressure ratio, and regular vehicles are 9/1. Not exact.

What up fellow KC 4runner owner!! Actually I grew up there, 2 years ago I moved to SD. Are there places to offroad there?
 
ok king! cool, I live I-29 and barry road, up north about 5 min south of the airport,

no offroading here sucks! there is some parks about an hour and a half away but most of the good trails in in the ozarks, so I'm a ways away, o well, good to see someone from this site was kinda near by
 
If your 3rd gen runs better with 91 then you are just masking another problem since unless you are SC'd 91 isn't getting you any gains on a properly running truck.

Higher octane is for high compression or forced induction engines and higher octane fuels are actually less combustible and have a more stable point to which they ignite. Cheaper gas can cause misfire before the spark plug fires caused by the heat of the compression thus high performance engines require 91 or higher.

If you're throwing 91 in a NA 3rd gen then you are just throwing money away.
 
Have a mechanic look at it and ask questions since if you have a pinging problem on recommended fuel you might have a timing issue or a possible bad plug or something but using premium as a fix might mask a bigger problem and could be more costly.
 
UPDATE:
i work at a mechanic shop so i talked to my boss and he let me bring my car in and i spent about an hour with the top mechanic, looking, listing, talking, looking at the computer, and finaly narrowed it down to 2 things....

(i hope its this)- it may be an exhost leak.

OR... (202,657 miles currently)

a bad lifter,
this would be caused by sludge, warn cam, bad shim under lifter,

so i got some stuff to try and clean out sludge if there is any, and if it were the lifters, the tollerance is .10 mm. so its basicly a joke, its going to cost more the an arm and a leg, if it is a lifter i might as well get a new car,

i have been the only owner for 12+ years and taken good car of it, changed oil every 3-4K..


as for the 91 octane gas, they say it wont do anything, this sludge stuff i got may change it.

so what i am doing now is just waiting to see if it is worse when its on a cold start (which would be an exhost leak) or just keep driving till it gets worse and if it does, im SOL!

sorry for all that bad news fellow 4runner members and ill keep you informed. (sorry for such a long post)
