Celica Forums General Discussion Exterior Engine crap sound, why? :(

My 2k GTS engine has crap sound (loud like "tar-tar-tar..." whenever I push the gas hard at <3000 rev. I also feel some performance degrade. Everything is fine >3000 rev and VVTL-i still kick in. Any idea whether it's a serious engine problem or the exhaust problem?

warm up ur engine(drive slow, smoothly apply gas) b4 you step on ur gas hard, try that, if it still happens..IDK...

a warm up might be good, if the problem persists i suggest take it to a mechanically inclined friend or even worse..an actual mechanic . lol just don't take it to pepboys, right?

If it only happens at high speeds it might mean that there is something loose under the hood(mechanical). Take it to someone who has experience working on Toyotas if all else fails

yup there is probably something loose its your lift bolts very common in our older models i'm changin mine this weekend myself but if ur under 60k miles it will be coverd under warranty!

heres a link for ya more on this... more info click here! also on the bottom of this page will be a link click on it and it will bring you to the TSB out for this problem! good luck

It shouts at any speed. Seems like it is tough to pick up until it hits 3k+ rev (can insufficient air supply by bad air filter caused the problem?). The noise is frequent ta-ta-ta and loud. Thanks for the suggestions

maybe your in too high of a gear. I know that if i'm going up a hill in 4th and should be in 2nd or something my engine makes that noise. Or ... you coud have an auto and this would be a totaly useless response

Chris, what problem does those defective bolts cause?

alot could blow you engine from my understanding i'm changin mine come monday! ummm the 2 bolts are ur lift bolt one is to ur intake and the other is ur exhuast and i get a ta ta tataat rattleing type vibrations werd noise after hittin over certain rpms and but also have been noticing power loss attime but people say you should look at them every 10-20k miles but i think you can go longer... the older model 7th gens are the only ones affected with this i guess cause of the bolts they used now they use different bolts longer or more tapper or maybe less of a taper not 100% sure but if you haven't changed they i couldn't hurt to do it now just in case you know

it might not be the answer to ur prob but least ur'll know thats not the prob and can cancel that out plus don't have to worry bout ruinnin ur engine from that!

the bolts are 43cents a piece and if you are doin what i'm doin( changin everything the TSB says to) then i will cost like 35$ not much at all considering it will cost you over 4k+$ to get new engine trust me i know been there done that no fun but it wasn't from the bolts but i know mine need changing !


good luck anything else let me know!

Just got my GTS back from the dealer (still under powerstrain warranty), they inspected the bolts and said they still in good condition. Surprisingly it's the leaking from the exhaust pipe (no more warranty ). So you know it may be a symptom of leaking exhaust
