I have a '97 4Runner 3.4, V6, 5 speed. It has a ticky motor when it gets up to temperature, when I rev it over 3000 rpm. I can shut it off for about 5 minutes, at which time the motor is still up to temperature, when I start it back up the noise is gone until it gets hot again. Could this be from a plugged cat, as it would create back pressure and make and exhaust leak? I also think it has lost power. Any help would be appreciated.

 

Hey NSB, first off congrats on your first post second how many miles you have on the clock? My 2003 50k "old" (for lack of better word) engine has a slight tick to it but I think it's just part of owning a Toyota. Could you get a sound clip?

 

it has 204000 km 125000 mi ,

 

i have a tick too but i swear its a toyota thing.. compare it with another 3.4 if you know anyone who has one and see... we call it the taco tic... welll i call it that :-)

 

mine had that tick , i put my oil in it now its gone. Also my 1999 z1 had a tick its gone also. I was told it was just a toyota tick but i got rid of it. 204k as of now quiet and smooth

 

I assume you mean teh AMSOIL oil? Which one? the 0w-30?

 

I acctualy put the 5-30 XL. Its not one of the 25k mile oils. its a 7500 mile extended drain oil. Its the cheapest of all the oils. I want to run it for about 10k and get a UOA. After this test i will prolly use 0-30 and run it for 25k.
If the test on the 5-30 comes back good i can keep running it, I want to see how it holds up.

 

Well hate to thread jack but i am going to be changing my oil when i get my supercharger installed and was thinking about AMSOIL anyways.

I change my oil every ~5000 miles no matter what the oil says anyways, just the way i am. so what oil would be the best oil/filter to use?

 

You could run the 5-30 XL and a Eao57 filter.If you are going to change your oil every 5k theres no reason to spend the extra money on a oil you can run for 25k. The filters are a little higher than most but they filter great. You can run a 0 wt oil it has a little better flow for cold starts,when they get warm they are almost the same. I can help you get it at my cost if you are inerested when you do it next.

 

no offense but oil doesnt have anything to do with the tic.. imo.. maybe a much heavier oil to dampen the sound but in reality oil will not kill the tic. i would need some substantial proof bc i have tried every oil under the sun and notta. same ole yota tic

 

Well mine had a tick when i bought it with197k on it. I changed he oil at 199k,it has 204k on it already its been gone ever since. You can come listen. I was told it was a toyota its gonna tick. It doesnt so im happy

 

maybe your tick was different i dont know without listening but again i have tried to rid the tic but nothing and i have heard countless other 3.4's with the same tic and they have tried motor cleaners and oils also. notta..

 

Mine kinda did it all the time, sounded like it was comming from the topside somewhere. I never could narrow it down. I didnt like it tho

 

Is the tick not the ttttappets?

 

Sounds like a nasty STD

 

tried having your head torqued maybe ?

 

yeah i would make sure its not just the injectors as they are very loud one some motors, also check your valves as they will create tick as mentioned above if slightly out. If you wana pinpoint the problem get a mechanics stethescope, or just a long big screwdriver and put your ear to one end and put the blade against various portions of the motor until you narrow down the location of the tick.

 

it doesnt bother me. i am used to it but it does get magnified when you are in the Mcdonalds drive thru and the sound bounces off the brick wall. tick..tick..tick..tick..tick its very rythmic. now if that tick wasnt rythmic i would really be worried.

 

Yes, i know i was in teh drive through the other day and the piple faced kid was looking at me funny when i have my head stuck out the window and am reving the engine.

 

I mean "Taco Tic" sounds like slang for some nasty type of STD...thats all
