If there a way to tell if the rocker arm has rotated? I havn't replaced my bolts yet but when I hit lift it doesn't feel as powerful as it did a few months ago, if it has rotated is there anyway I could straighten it up again?
whenever i push the car up to 8000rpm, my headgaskit gets messed up. does this have anything to do with the bolts? or sth else? if sth else, what can it be?
Should I be worried about my lift bolts being broken if im driving an auto gts? I have sportshift so i rev it up to 7800 in first and second gear sometimes.... Im worried that if they are broken im screwed pretty much. Whats the best way of getting the broken piece out?

Well depending on if your rocker shaft is rotated or not it could be easy or hard. if yoou can see the broken piece straight on the rocker shaft hasn't rotated. Best method for that would be bolt extractor. If the bolt if offset from the hole or you can't even see it the rocker shaft has rotated. Best/practically only method for that is LiftBolt tsb. I am almost done with the TSB on my car. Wasn't really hard. I am also making a guide on it. PM me if you want more information.

Yes you can tell if it is rotated by shining a flash light in the lift bolt hole. If you can see the bolt straight on it hasn't rotated, but if it is offset or you can't even see it than your rocker shaft is rotated. PM me if you need more info.
If your Lift bolts aren't torquing down strong enough after you drill them out... take a look at this post to get some help. Remember, proper torque on these bolts are important so that Lift can engage as strong as possible. Any play or looseness will weaken the Lift. Then in my case, after stripping the threads, my bolt actually shot out of the hole. Anyways, anyone reading this, I hope you won't need to retap and thread, but here's all the information if you need to make the hole strong again.
Hey guys,
I'm getting ready to change my liftbolts I own a 2000 Celica GT-S with just over 80,000 KMS on it, I'm assuming the original owner never changed the lift bolts, I'm supposed to pick up my new bolts tommorow. I still get really good lift from just over 6,000 RPMS right up to the limiter. My question is when I'm installing the new bolts, should I lube them first? Should I put a thin layer of oil on them? Or just put them straight in right from out of the package? My second question is; is there any other tips people would like to pass on regarding this installation before I begin? Thanks.

It all depends on if the bolts are the newer or older version. If they are the older ones lift will still be just as strong because the bolts are not tapered to a point.

You don't need to lube them or anything but a good reccomendation is to put some of the blue thread lock on them. Not the red stuff but the medium thread lock. It comes in a blue bottle. This will prevent the bolt from rattling out of place. Also is isn't totally necessary to torque the lift bolts down to specs it is a good idea. The goal hear is to keep the bolt from coming out of the hole and keep the rockershaft from rotating. If u have any ?s pm me.
I don't know if this has been mentioned already, but i was just on the phone with Toyota for 20 minutes!!! They didnt know what the hell a lift bolt was. they refer it to as "Flange Bolt" and if you guys have a problem with them, just tell them the parts number for it, which is on teamCelica's site, 90105-06293. Good luck with the installs!
Consider them a maintenance item. All are subject to wear. The intake bolt is subject to more wear due to the action of the VVT Timing Controller. You should inspect at a particular mileage and determine a personal replacement schedule. It will likely vary from engine to engine. I'm currently replacing the intake every 30K, exhaust every 60K, just to be safe.
Yes, please, is there any way to find out if the work has already been done? Would it show up on Carfax? I'm looking at upgrading from GT to GTS, but don't know that I will if I don't know with reasonable certainty that I'm not going to be looking at another couple grand for repairs.
