I've seen a few people say not to replace lift bolts on our 2ZZ's because they don't have failures. I did my valve cover gasket last night @ 129k miles, and did the lift bolts along with it.

 

Now I think this wear definitely promotes lift bolt replacement! One was getting cut into pretty good, and the other was much more minor.

That's how mine 03 look when I change it at around 150k.... Replaced with new style silver bolts. Hoping it won't ever need replace again.

After seeing those, I don't understand why people insist on not replacing them. Only matter of time before it snap.

Same thing when we did 2RISMO's 03, same mileage @ 150k.  $3 for new bolts made it an easy decision.

Why that part is wearing like that?

Does it affect performance?

 

Dyno oil vs. Synthetic oil ?!?

Lift bolts had a problem with snapping on early 2zz's, particularly Celica's.  They redesigned and fixed it for the Matrix & Corolla, but it doesn't stop everyone from changing them out every so often for the reasons above.  If they do snap, you'll lose lift, and have a b**** of a time getting it out.  I don't know if it affects anything outside of that.

 

Oil MAY have a hand in reducing wear, but just treat it like a long-life service item.  That's how they wear.

I replace mine every 80,000km's on my 05 corolla XRS.  I know people are going to say "why? they're the new style bolts and don't need to be done!"

 

I've had to drill out and replace a broken lift bolt in a friends 2000 celica.  IT SUCKED!!!!

 

For less than $4 in parts and about 20 mins worth of work.  Why the hell not?!?!

Because they look like that after 150k, and it wouldn't affect functionality.

 

You're looking at 400k+ before it wears down enough to become a snapping hazard (and that's assuming he used proper oil change intervals/oil).

 

And because they're known to snap when attempting to remove, which becomes a much bigger problem.

 

Frankly, 2zz motors rarely last 400k anyway.

You're absolutely right, but for $4 and a bit of time.  I think it's worth replacing.

Oh, belly-laugh at the "they don't get worn".  I guess those guys like drilling out bolts.


...Did you try hitting it with a hammer?

Since my purchase of 05 XRS never tried the lift, just ran only abt 1200km or so..how does it feel when the lift kicks in arnd 6800rpm, i find am generally making 3000-3500 cruising rpm on hwy & 6800 is quite a lot to go. Is it recommended to try 6800 at 4th gear n move up..?

PO never changed bolts from what i hear sitting at 195k kms, was told it was always synth oil changes, i shld be checking on them one of these days. Appreciate.

You'd lose your license well before you got to 6800rpm in 4th gear.  Try 1st and 2nd.  Redline in 3rd gear is 150km/h in a Matrix.

In Ontario the cop is judge & jury on the side of the road and can take your license and car on the spot if you are charged with exceeding the speed limit by 50km/h or more.

lift in 4th gear is recommended only for track days.

 

https://youtu.be/4F04DBlnLUo?t=2m

hear the downshift to 2nd prior to the turn

top out 2nd

top out 3rd

almost top out 4th prior to braking for the hairpin

well over 100 mph. those are "go to jail" speeds where I come from.

I would check lift bolts more often than not. Particularly if you spend lots of time above 7000 rpms. When we pulled mine out at 126,000 miles they were showing early signs of wear. Errrrmm okay they were a track day away from a bad drive home. $3 in parts and easy to get to. Change them every 60-75,000 miles for safety.
