Can not feel my lift.

[cooltoy2000]

Last few days I have not been able to feel lift. It's gets noisier around those rpms, but don't get the usual kick in the seat feeling. Anybody experience this. Should I take the car in? It has been really hot lately, could that be the reason? Thanks.

[jotan82]

hmmm
do you think maybe you just got used to it??? over the year and a half i noticed that the lift wasn't as brutal as it was when i first got my i/e... but that's cuz i got used to it...

[cooltoy2000]

I do not know if that is the case. I felt it fine last week. I do not use that often (once or twice a day maybe). Can the dealership tell if there is lift or not?

[gts24]

have you checked your oil lately? could be a little low. do you routinely check it?

how many miles are on your car?

[cooltoy2000]

Just checked it this morning. Seems OK. Got my oil changed in May. I have 9000 miles on it.

[2002GT_Celica]

Are you sure you have a GT-S? Because if you have a GT you won't feel lift without a really active imagination.

[cooltoy2000]

You funny.:stupid: :D

Do you step on the gas really hard when you try to go into lift? I had the same problem a while back. I couldn't feel lift so I took it to my dealership and had one of the technicians test drive it with me. When he test drove it, I felt lift everytime he went into lift. He told me that the harder you step on the gas, the more you'll feel the lift kick in. So everytime I go into lift, I try to step on the gas really hard and I feel lift kick in hard all the time. Hope this helps. If you still can't feel lift after trying this then I sugges that you take your car to your dealer.

Wow, not stepping on the gas enough... never had that problem :chuckles: :naughty:

seriously, I have an indent on the right under the accelerator on the floor of my car. The carpet is worn out from the accelerator being mashed into it all the time. :D

[Chris25NJ]

First make sure level is good, and the car is warmed up.

Once or twice a day is pretty often to be hitting lift. I try to only hit it like once a week (sometimes it's hard to restrain) Apparently, the pin that is triggered when you go into lift can wear out and needs to be replaced. If you're hitting lift that often it is possible, but not likely with only 9000 miles.

[djm221]

The hot weather probably plays the biggest part in the 'problem'.

Why would anyone routinely rev past 6,000RPM with anything less than WOT?

[JaySong]

This is not the problem. I don't know if you saw the porevious no lift posts but replying with comments like"you sure your car is warmed up or are you giving it a full throttle" is inane.
It's a bolt breaking off that drops down to the rockers disrupting oil flow.

i go into lift at least 10 times a day.... i can't help it, i'm a lift addict... although the gas prices lately have discouraged such lead-footedness...

I'm glad to hear that actually. With all the talk about this pin that wears out, and engines dying without mishshifts, I try to be easy on the car.

[djm221]

Uh, that pin wears out after many, many uses, not 10.
If you only hit lift once a week, I feel sorry for you, denying yourself the pleasure.

I hit it several times a day, and my engine is as strong as ever with almost 35,000 miles and no break-in :AF:

If you hear the sound change, and it revs to redline, it is most like working. Theoretically, the change should not be so abrubt, and some dynos have shown that happens sometimes.

[2002GT_Celica]

Umm...if this hitting lift makes your engine blow theory was true, then I doubt they would have put it on the Celica, or the Matrix for that matter. Why would any car company in their right mind put something in a car that would make them lose millions in warranty work? The implication that some magical pin wears out is absurd. If you drive your car daily and only use lift once a week, you should have bought a GT. :chuckles:

[gts24]

I've got 51k on my car now. and I hit lift all the time. The engine feels strong as ever. and some days... feels stronger than when I originally bought it.

[JaySong]

As i replied previously, this is caused and i can speak almost certainly that a bolt tip inside the VVTLI cover is broken and is affecting the oil pressure on the lift mechanism. You can check this by checking either the oil pressure or the vvtli function on the scanner.
In my case, the lift strength was varied. Sometimes it was non-existent, sometimes it was weak and once in a while it kicked in strong. That few times it was strong, the bolt tip was out of the way allow the lift mechanism to line up properly. But most of the time the mechanism does not line up all the way.

The way to tell is to look at your 1st gear lift to tell if you see any power loss.
A friend told me about this initially and we opened under the vvtli, you remove the metal cover(don't know the correct name of it) and right there there are two bolts. At least one of them was broken in my case cause the problem.

To clear up the misconception on this topic. It is a smooth tip of the bolt tip that breaks off not a pin. This occurs mostly if someone opens up under the vvtli-cover and overtorques the bolt. This bolt mind you has nothing to do with the rockers. The reason it is frequent for mishsift people is that the dealership over torques them. I, myself never had misshift but i did notice that someone opened up this area. IT is however, not ruled out that it doesn't happen automatically. Being said this, the lift mechanism isn't the issue. Some people like 2002Gt_celica think that the lift mechanism has a shell life but it isn't true.
If anything, the bolt breaking is the issue which drops down inside causeing this problem.
Like I said toyota is aware of this and are currently looking into this matter to make changes so the bolt does not break off

[cooltoy2000]

Great info. Thanks guys.

[djm221]

I don't understand how lift strength can vary. Is it because not all four cylinders get the valve lift - meaning the pins aren't under all of the rockers?
Anyway, the pin wearing down thing that was mention refers to the pin that goes under the rocker when lift is engaged. That edges of the pin will wear a little over time. The technical paper on the engine acknowledges that, but apparently, it isn't too big of a deal - as in it must take many thousands of lift engagements to make it an issue. Once it starts wearing, the pin won't go in the "first try" and will may take a few revolutions before it goes it.

[Purple_GTS]

hehe...I almost never go into lift. Maybe once in a few weeks..or when i street race someone. Other than that, I drive below 3500 RPM..

Yeah..i should've gotten a GT, but i wanted a GTS :D:D
I won't have to worry about my bolt breaking off.

Oh yeah..excess revving of engine will break other parts too..not just the bolt...Wears down engine performance..

[Purple_GTS]

I suppose VTEC doesn't do this, ah?

[X-EVIL-X]

well i drive my car hard all the time and got it dynoed a few months ago at 40000 miles and a 174 to the wheels isn't to shabby for what its been threw.
if you dont go into lift than your missing out on the real car.
should of saved a few thousand and bought a gt.
lift is the nicest thing and i see it a lot:)

I hit lift in every gear every day. Snapped the set bolt on the rocker shaft on my 02 in 10K :) Aint leases grand :)

[Griffin]

Okay to clear something up

The MOST common reason we have been able to CONFIRM on the board is the set bolt for the rocker shaft breaking. When it breaks the shaft spins and the oil holes only line up sometimes, this (as Jay says) causes a lack of oil flow to the actuator pin in the rocker assembly hence denying lift. This can result in "late" "weak" or intermittent lift operation. I had this on the 02 I was driving and I saw the same thing on Jaysong's '00.

[Chiznarles]

hitting lift is like masterbating.. when you first discover it you do it all the time.. then you kinda slow down after a while.. some ppl do it 10 times a day! i usually just reserve it for when i'm alone at night and no ones around..

hitting lift that is.

LOL, that's a great analogy. It's soooo true. :chuckles:

Hmmm...this kinda worries me. Will Toyota do a recall? Will it be covered under warranty? How can we check to see if it's fracturing or going to fail? I'm scared to hit lift now....my life is now over! hehehe j/k...seriously tho, what can we do to prevent it besides abstinence?
