oh man buddy! im sorry to hear that atleast you have the good ole ST right?
ill help you with that as soon as i can.

[lagos]

i think "OH SNAP" would be appropriate here

what car did it happen to? when was it last changed?

[malpaso]

sad to hear that mate...

[LewFX]

i got one for sale

[presure2]

that sucks D
didnt you already buy the tbelt and waterpump ect for when you were going to do the headgasket?

[Batman722]

yes. I have a timing belt, water pump and a metal head gasket sitting in my kitchen

I got the car back to the house and I'm just going to wait until it gets warmer to replace everything.

its supossed to be in the 50's the next few days...

[celicaST]

thank god our engines are non-interference

I would love to but I have no time off to do it. My new plan is to take 3-4 days off in a row in late April and bang this out. I need to make sure it's warm (I hate being cold), research everything down to the letter, and have no fear - and maybe have you or the horniak give me a hand on one of those days

I'm just glad it broke when I was so close to home last night...

[hurley97]

i'll help any way I can baby

ehmmm what????

[WALKER]

Sorry to hear that, good luck getting it back on the road.

Try and take lots of pictures when you do your headgasket replacement as I will be doing that sometime in the near future.

[tomazws]

Sorry to hear about your incident.

Is your engine ok? I'm not quite sure what the consequences are after having a snapped timing belt.

[6gcSTVT]

thank god our engines are non-interference

ehmmm what????

I want this question answered by the knowledgable on the site bc i have been wondering the same thing, are our engines interference or not? Bc I have been wondering whether I should be looking into changing my belt just to be on the safe side since i've put 41k on it since i bought it and i have no clue if it is still a stock belt or not. I plan on doing road trips this summer and i don't want my car breaking down anytime soon.

EDIT: Non-interference means when the timing belt breaks the valves are Not involved... ( i believe)

Yes they are non-interference. Shouldnt be any damage to the valves.

ill help fo sho. just need to get my own wheels spinning first. and i like the being warm idea also.

[6gcSTVT]

What celica engines does this apply to? I had a friend who was getting rid of his 93 gt and the timing belt broke and his mechanic said the valves could be bent, he gave it away for 300 bucks...i believe it was a 5sfe? Thats the only reason why i didn't touch it at the time (Years ago).

[Supersprynt]

Interference motors. Might not be conclusive but its a start:

1986-95 1.5L Tercel
1981-83 2.2L Pickup
1984-87 2.4L Pickup
1982-88 2.8L Celica Cressida
1987-94 3.0L 4-Runner

Unfortunately that mechanic didnt know whether or not it was interference. the 5sfe is not.

[quicknstyle]

or he was just trying to make some money...

[laff09]

Theory #2 sounds more probable

[jdg371]

7AFE and 5SFE our NON interference.. sadly my 2ZZGE is =[

[laff09]

What are the "pros" of having an interference engine?

[Hanyo]

What are the "pros" of having an interference engine?

Interference engine - A conventional modern engine design. It is a configuration of which when a valve is open at it’s greatest point, it exists in the same area that the piston travels into, and will be in shortly. The benefits of this design are a closer tolerance, shorter engine, more freedom in combustion chamber design and valve angle. The downfall is if and when a timing belt/chain fails, the valve will not not close, and the piston will strike it. (http://paultan.org/car-jargon/)

[97lestyousay]

I can't believe I didn't see this, that sucks dude.
Hope you get her going soon.

your friend got jipped

[94celicadude]

sorry to hear that, and hey if your looking for warm weather, weve been in the high 70s all week, come and do it over here, i have a nice big shop to do it and weather doesnt matter either way. Good luck with the repair.

[6strngs]

I had no idea there was such a thing as a non-interference engine. somebody donated an engine to my auto class that had a timing belt break on it (straight 6 BMW motor). we pulled the engine apart and a couple of the valves were severly bent. surprisingly the pistons and rods were ok though...

knowing the 5sfe is a non-interference definately gives me some piece of mind though.

[Silver94CelicaOw...]

Damn Dustin.....I'd be willing to help out if I have a few days off when you do it.

Might just be easiest to yank out the whole engine, then while its out index everything and do the head gasket, timing belt, and any other parts you may want to refurbish while its out. All that would be required would be to lay the whole harness on top of the engine, remove the axles, coolant and p/s lines and then hoist that mofo outta the car once the mounts are unbolted.

If all the parts needed were on hand, 2-3 people could get it done within 2 days, easily. Let me know if you'd like a hand, I'll come up if you want.

Change the belt regardless. Even if no other damage is done, you will still be stranded if the timing belt breaks. If you are always close to home, it may not be a big deal, but it's not something I would want to happen on a road trip. You would have to get the car towed, and you probably won't have options like doing it yourself or searching for the best price. I'd replace the water pump at the same time and check the oil seals for leaks.

I've pulled a few engines before Corey

the problem is I don't have a hoist or garage here to pull the engine, all the work is going to be done outside my house on my street (at least I live close to the end on a dead end street)

I'm gonna tackle this in a few weeks (once it gets warmer), I know I can handle it, I just need a few days off in a row and I'll be good to go.

I thought all 2000 and up Toyota motors are free-running!?!?!?!?!?!?!??

[alltracman78]

It's actually the other way around.
Most 00 ^ are interference.

For the most part [there ARE exceptions, such as the 2UZFE I believe is interference] if it has a belt, it's non interference [freewheeling]. If it has a chain, it's interference.

Dustin, I MIGHT be able to give you guys a hand if you need it.
Dunno.

[Celicaguy13]

Yay for me 2... My belt stripped the 23rd. Just yesterday I was able to get a wrench in there. Took me 1 1/2 hours to get it apart, now just waiting for the belt and tensioner.

BTW on the ZZ engines you have a Timing Chain, so it's less likely to snap like a belt.

[Batman722]

OK I'm thinking that next weekend (the 28-29th - weather permitting) should be a good time to get this done. Stef and I pulled many of the accessories off the head today and by tomorrow everything should be set for the head to come out.

So if you guys can give me a hand either Saturday or Sunday (or both) this is when I'm gonna need some help.

what I'm hoping for is to do the head gasket on Saturday, then finish up the timing belt/water pump on Sunday.

[x_itchy_b_x]

i don't think i have anything planned on those days. just let me know where im going

[Dr_Tweak]

Just curious, how did you determine that the belt broke? Did you actually pull the cover and check?

-Doc

[presure2]

i had him watch the rotor on the dizzy and try to start the motor.
no worky = snapped belty

[alltracman78]

Or snapped camshaft :bitesnails:

Dustin, are you doing this in Newport?
You don't have air, do you?

[Batman722]

doing it in Newport, no air

both camshafts are fine Jeremy

[alltracman78]

Ah, all good.
I'll try to make it down there, but I work 'til 4PM on Sat.
If I can make it, is there anything special tool wise you guys might need?

I was kidding about the camshafts. Sorry

[alltracman78]

You know, it didn't register that it was this weekend until just now....
How far along are you?

I'll try to call Manny tomorrow. I have something going on.

[Batman722]

we didn't do anything on Saturday, but today (sunday) is the day it should be going down.

[x_itchy_b_x]

oh it went down! i'm sure that paper towel we left in one of the cylinders will be fine.

[presure2]

oh it went down! i'm sure that paper towel we left in one of the cylinders will be fine.

or the little plastic thingy i threw down in there...i cant remember if i grabbed it before we put the head back on or not...lmao

D, just make sure steff is nowhere near that engine when you try and start it,...i'd hate to see her get burned...
good times.
get her all buttoned up, i wanna see that beast back on the road!

[slvr_celica_GT_8...]

my belt was done once back before i had the car when it had 60k on it, the cars got 125k now so im going to get it done soon do you guys know what id be looking at for price to have it done i know all shops vairy but is there a ballpark someone can give me thanks

[Batman722]

yup it happened. The head gasket, timing belt, and water pump went in really without any snags...except a broken sensor out of the water neck. It's the one closest to the head, I think it's the water temp sensor for the EFI.

I'm gonna get everything buttoned back up in the next few days after work, should take a couple of hours to get it 100%, I just need the time and daylight.

Thanks to Manny & Jenn, ze Horniak, and Steff <3

[Defgeph]

good stuff Dustin. I happy you're almost up and running again !

[Batman722]

Thanks Jeff.

I forgot to mention the pass side axle that didn't hold up to the strain of no mounts o well, now both the boots are torn on that side

it was worth it

[Batman722]

[lagos]

you got ever last mile out of that belt.. haha

[DSToyo]

maybe i didnt catch it, but how many miles did you have on that belt?

[hurley97]

maybe i didnt catch it, but how many miles did you have on that belt?

146,441 IIRC from writing it on his sticker for him

[LewFX]

ribbed for her pleasure

[DrAg1n320]

i know for sure it's not an interference motor. One way to know for sure whether or not it's an interference motor is while you have the timing belt off, you should be able to spin the crank with no resistance, meaning it's not hitting any valves. so you should be safe, now if your replacing the head gasket, my tip to you is to BUY EVERYTHING, because while you have the head off, it's a good idea to replace the valve seals, clean up the valves by lapping them, and clean the whole head because after you are all done, that motor will last another 200k miles.

[Batman722]

update

since we got the new HG, timing belt, and water pump all in on Sunday I have had to time to put everything back together until today. I did do a little bit each night (in the dark ) but I had half of the day today to finish all the loose ends.
So now I have everything back together and I replaced the broken temp sensor with a spare and everything is 100% now. No CELs, no clanks, no leaks (yet), no problems.

During the downtime I had I did manage to do a few upgrades like a new HU, new speakers, 7th gen wheel, adjustable rear sway bar end links, new front bushings, replaced a bad wheel stud, painted the cooliing panel, J Speed bar and valve cover black, fixed a squeeling front wheel (thanks Manny), ect..

I have to say, it drives better than ever, rides like a dream now

once again, big thanks to Manny & Jenn (presure2), the Horniak(x_itchy_b_X), and Stef (hurley97).

next is paint...and boost

[KAOS]

Hey guys; my belt actually snapped... broke right off... what the hell am I supposed to do for lining up the camshaft timing sprocket?? Do I just turn it to line up with the "U" notch??????


PLZ HELP I'm MID-REPLACEMENT AS I WRITE THIS.... !

[azian_advanced]

yes

[KAOS]

I'm not going to screw anything up by doing that?? (timing wise)

[6strngs]

It should say in the BGB. Which you can view for free at celicatech.com if you don't have one

[KAOS]

It should say in the BGB. Which you can view for free at celicatech.com if you don't have one

The bgb that Walker and are are using doesn't seem to say anything about a snapped timing belt, just how to replace the existing one.

Unless we missed that portion....

[azian_advanced]

unlike the crankshaft which revs two times per engine cycle, the camshaft only revs once. so you can turn the camshaft pulley until you see the U-notch without messing up the timing.

the real problem lies with the crankshaft. the bgb doesn't tell you how to set the crank after the belt snaps. since your belt snapped on you, you won't know whether the 1st piston (the one closest to the timing belt) is in the beginning of the intake stage or combustion stage of the engine cycle while the crankshaft pulley is on the zero degree mark. but there is a way to figure it out. you need to set it to the beginning of the intake stage (ie. piston at TDC), here's how:

Alternative method: This step may require 2 people to do. Remove the #1 spark plug, put your thumb or hand over the spark plug hole to seal it and turn the crankshaft pulley until you feel the air push out. This means the piston is in the compression stage. You need one more revolution to be at the beginning of the cycle (ie. at the beginning of the intake stage and end of the exhaust stage). Use a long straight object like a straightened coat hanger and put it through the spark plug hole lighly resting on the piston inside. As you turn the pulley on its final revolution, the coat hanger should rise to the highest position. Adjust going back and forth on the crankshaft pulley per unit degree until you reach maximum height.

Perfect - thats what I needed; thank you Gerald.
