Quick question. I've heard in some cars that a timing belt failure is a catastrophic failure in the sense that the belt flies off and destroys stuff. Is this true in the integra, or will the engine simply stop running until a new belt is put on. I ask because I know I should get a new timing belt, but I just had to pay for some other fixes and the cost was too much to bear this month. Please let me know!

 

Timing belt slippage alone can cause catastrophic engine damage. A broken timing belt, you can almost be certain you'll need a rebuild.

 

Broken timing belt on most (but definitely not all) Toyotas = stops running

Broken timing belt on almost any Honda = possibility of bent valves, holes in pistons, completely destroyed cylinder head combustion area, and more.

Those are just the very immediate and most likely damages.

One of the big selling points for my car was that the timing belt was done by a shop 15k prior with the date of service, shop address and phone number.

 

i bought my gsr for 1900 without a timing belt. i guess i just got lucky

 

Do the work yourself, The hardest part is getting the crank bolt off. Apart from that is it all basic hand tools and actually pretty easy to do.

 

So doing a timing belt is easy? I always assumed it was pretty hard? Dont you have to degree the cams? when would be the best time to do your timing belt? In other words whats the most someone should put off doing the belt? Im at 92xxx and have yet to do it. I was thinking of getting it done before the 100,000 mark.

WTF? what does toyota have in place to prevent damage from happening when the timming belt rips?

 

suabrus are the same way, when a belt breaks, itll just leave you dead on the road.

yeah, when a timing belt goes on a honda, it can almost gaurantee your engine is totally boned and will need to get replaced. i dont know about doing a belt yourself, im sure it cant be TOO hard, but it can be VERY tedious and you just need patience.

but what makes that possible??

how is it that they avoid damage when the timming belt rips?

i could see how that could work on an engine with super low compression like a suburu or evo turbo engine.. cause the valves come no where near the pistons compared to high compression honda engines which come super close to the piston..

 

It's called a non-interference engine. You can leave a piston at TDC and rotate both cams 360 degrees. It's engineered so there is still clearance, and the valves won't touch the pistons. My Supra will just shut down if the timing belt snaps because it's a low compression engine with very large valve reliefs in the pistons. Yes, mine is a turbo model but the NA engine is non-interference as well with about 9:1 CR.

Others are interference-type engines, where you can NOT rotate the cams 360 degrees with a piston at TDC because they will touch.

There's nothing to prevent a timing belt from breaking, but there's an engineering design to prevent catastrophic engine failure in the event of a timing belt letting go.

 

Dead on, non-interference vs interference.

 

if memory serves me right you where supposed to do it at 75k. 100k is as long as i would put it off for.

I think it is pretty easy to change out. The hardest part was getting the cams aligned again when putting the belt on. Once i figure out the marks of the cam gears and the marks on the crank pulley it was easy. It took me a good day to do it, but i took my time and kept checking back on an old HT thread for info. If i was to do it again I would say it should take 3-4 hours.

 

I want to get it done but the dealership is charging me just over 700 and im not sure i would be able to do the job myself. The worse part is its cold and snowing now in Chicago so i would not spend a day outside working on it but at least now i know its the next thing im going to do. thanks

 

700, that is such a rip off, i did mine in 2 1/2 hours by myself with hand tools. They got air tools and lifts, so how can they justify charging 700 bucks.

yea right!!! mitsubishi engines are worse about bending valves and puting holes in pistons than a honda.

Dealerships like to charge. Like i said i would not mind attempting to do it but i don't want to do it wrong and have to pay someone to come out and fix my mistakes. I have a manual and it looks pretty easy until you have to degree the cams...Does anyone have a link to a DIY timing belt with lots of pics?
