***i am soooo p!d off, out of all the cars ive ever owned ive never broken down, and a jap being the most reliable cars it just dies end up coming home on a truck.****ahhhhhh ***

ok im calm now
please help.....

Has it got fuel in it, you may have a faulty gauge and think it has when it hasn't, if it's got plenty of petrol in then may be fuel pump.

Cambelt

you've got me thinking, cus once i put fuel in and the needle didnt move from the reserve mark for ages and the light didnt turn off.

Only one way to find out couple of quid in a can and give it a whirl, defo make sure the cambelt aint broke 1st tho cause if it has the more you try and start it the more damage will be done.

Yeh mate, basically start from scratch, is it getting fuel, take off the pipes and turn it over if it comes flyin out then on to the next, is it getting planty air it might be possible that it got blocked, uncommon but it could still happen i guess. Is it getting a spark? take out a spark plug at a time and turn over once, you should see a spark. I assume your battery have enough voltage and thats not the issue or else it wouldn't turn over.

When was the last time the filters were changed, and do you offen run it rite down almost beyond reserve as this could result in the crap at the bottom of the tank being sucked up into the lines and clogging it up.

Other than that if its not showing any warning lights then it might be time to call in a garage to take a look.

Crap in the bottom of the tank, is going to be, at the bottom of the tank, if you have full tank tooo

Think about it............would it not be at the bottom of the tank, say you leave it overnight on the drive

true but im only going on experience, my old jeep had a dodgy fuel guage and i thout it was half full but it was so dry all the gunk that had collected up over the years got sucked through. Choaked all the fuel lines rite up to the fuel line. Happened in the middle of a snow storm up in the mountains where there was no reception, i wasn't happy so after that i tend to use that as a scape-goat till proven otherwise lol.

my worst night mare !!

ive jst spent the last hour or so pulling it to bits, found the cambelt snapped.

now the question is, what sort of damge am i ment to look for now if i strip the engine, ive neve a cambelt before im going to give it a go myself.

the engine was idleing i was stood at traffic lights when it snaped ? so the engine was running slow what extend do you thing the damage will be ?? ive tryed starting it a couple of time aswel, take it thats bad news.

Hi,
Not good news generally bent or broken valves,damaged valve guides, possibly top piston damage,possibly cheaper to find another engine.
What was the mileage and was the cambelt due a change?

that sort of damage even if the engine was running at 1000rpm ?

the belt was changed at 72k-ish by previous owner. and not its just hit 97k

am upset

the damage shouldnt be as bad as that but wont be good but as it was on tickover it might be your saving grace as repair bills go

matey, the damage will have been limited if you didn't keep trying to get it going but your looking a valves 24 of them on the lex how many are damaged tho will take investigating, there is a section on here how to change the cambelt yourself but thats before it goes it will help but only to a certain point.

do u think its work just banging a new belt kit on and see if it runs before ripping the engine apart ?

that could cause even more damage mate,get it checked out properly and it will save you a lot of time,money and heartache.
a surgeon wouldnt just stitch up a wound without investigating it further would they

it shouldnt have snapped if it was done at 72 k..

could possibly indicate something else?? was there anything that it was catching on? where was the belt change done? was it a reputable garage??

Im not sure on the lexus what type of valves it has but some engines dont get damaged when the belt snaps.. my old civic being one of these.. more damage is cause when you try and turn it over it was the other type...

reduce the risk and get a decent garage to look at it and do some digging on the previous belt strange.. sounds a bit fishy to me..

I agree^^ very strange to snap after only 20k or so, was it defo replaced @ 72k was it done properly and was it defo the right belt? I would check everything that could go wrong when the belt snaps and find out exactly what does and doesn't need doing, no such thing as an easy fix unfortunately but better to get everything done at once than run into further problems a few miles down the line. Gutted for you mate keep us informed.
You could always get a Supra engine for it tho.

maybe they only changed the belt and did not change idlers causing premature wear to the belt

Going off what your saying. i do agree, i should have it checked out when i bought the car. because the belts never did sound as though they are running smooth...the sound was like,erm sounded like one of the pullies need oiling or somthing. u know like metal on metal but its not got enough grease. it sounded like that.

supra engine ?? would that require more modding, change of ECU gear box etc?

Yeah, and a LOT of work

WOW, theres alot of **** being spouted in this topic.

it will do no harm, on getting the timing set back to the correct marks , and putting a new belt on.

this will cause no more damage than "could have been caused" so far.

otherwise you take the risk of stripping the head off to look at a perfect head............. trust me, it has no damage!

when i ran my garage/workshop in Germany, if a customer brought a car in for a snapped belt, the first task, was to check with a belt on.

on most of the engines there was no damage and the cost was only the change of the belt and pulleys.

Thats what i meant!! Couldnt think of the right terminology!!

was the same on my old civic!! just put on a new belt and away i went!! wasnt sure if the is200 was the same..

Tis good news indeed.

ok back to reality.


my old man had a fiat back in the day. the belt snaped on that and the valve on that were bent not all of then though. thats what im dreading. i havnt got that sort of money to pay out at this moment in time aswell.

i am Right

There's another terminology as well I think - engines that do not damage the values, pistons and so on when the cambelt or chain snaps are referred to as "safe engines."

never heard that, the correct terminology is...[b]non-interference[/b]

Google it!!

Just thought some people may have heard of that term instead. I'd never heard of interference and non-interference before today - good to learn something new. Thanks

I'll not Google it, as a mechanic I'll use the correct terminology, but at least others that don't know can expand there knowledge with

Non-Interference (Safe) = snapped belt, no damage through Piston/Valve strike

Interference(not-safe) = snapped belt damage through contact of Piston crown and valve (possible camshaft and valve guide damage)

true true i agree.

if it doesnt rain tomz i think i might give it a go.
guess im going to have to take the other belts off 1st to get my hands in.

fitting the belt wont be to hard, how would i get the timing settings right on it ?

its not just a case of chucking on a new belt.

you will need to get hold of the procedure for changing the belt.

i dont have my workshop manual to hand otherwise i would scan it for you

i'll try and find a how2 on here.

if not then hit a trip to halford and buy a book.

i agree mat.. that is the correct terminology.. i justy couldnt remember it..

would also say that its prob worth getting it done at a garage to make sure there are no other issues and at least you will ahve some sort of warranty on the work..

do it right and pay once, cut corners and pay at lot more than once!

Click on REPAIR MANUAL then on ENGINE MECHANICAL and then TIMING BELT in the drop down lists will at least let you see whats involved in the cambelt inspection, repair and replacement

heres a question then why did lexus change the timing belt recommended change time from 100k miles to 60k miles if there is going to be no damage to the engine if its a possibility that the belt can break
and whats stopping anyone from leaving the belt on from the recommended change time if no damage will be done

Also theres a write up that was posted recently on changing the cam belt.

because it may be "non-inteference/safe/whatever" but its not fool proof and some damage may be cause somewhere.

That's interesting. A while back, on another cambelt discussion thread (I tried searching but can't find it right now), I posted that Wikipedia says all the Toyota 1G engines are non-interference, but I assumed that was wrong because so many people here seemed to say that snapped cambelts on the IS200 could cause major damage ! No-one contradicted this at that time. Useful to learn that Wiki is right on this one though !

[quote name='aaronabbott' post='591979' date='Oct 11 2008, 11:32 PM']and whats stopping anyone from leaving the belt on from the recommended change time if no damage will be done [/quote]
I would guess that it's because it's still a bit of a pain for a cambelt to snap in the middle of driving and leave you stranded !

may have skipped a reply but i would fit new cambelt with tensioner and idler.buy or lend a compression tester and check readings.take 2 readings on each pot so you havent made a mistake.hopefully alls well.if not new valves (not all of them).new head or new engine and transfer ya new belt to it.good luck.make sure that nothing has locked up on ya motor to cause falier.

I stand corrected Mat. I was just going on what generally happens when a cambelt snaps, good to hear the IS engine wont have those problems if the belt goes.

I wouldnt do just the belt tho i'd check the tensioners at least, prob better to change them aswell.

Only kidding about the Supra engine BIG job for ppl with deep pockets matey.

YES...if changing the belt, change the tensioner aswell!!

and it is also a good time to check the condition of the bearings in the water pump....and if needed change that aswell

So is that a defo Mat that it is a non interference engine as I have a auto data CD and it states that it is, I ask is that my cambelt is a little overdue for changing as I have been too busy to sort it.
