timing belt help

ok so my timing belt snapped on the highway doing 130km, i'm finally getting around to putting another one on now and i still havent checked the internals... what's the worst that can happen if i just slap on a new one and fire her up??

well nothing bad will happen if you "slap" a new belt on. what could possile happen to the internals is it could have bent a valve or like me it could have cause a hair line fracture in the valve and then overtime with heating and cooling make the valve break a chunk off.

Take the head off and check everything out. People break things from going less than half that speed when they have they t-belt snap.

People can break things not even moving..

so if i put on a new belt and start the car, the engine wont get any more fucked up? and will it run with bent valves?

I would inspect the inside before you start it back up...it will only make things worse for ya (if ya start it up b4 checkin it out)!

Yeah, who knows how much damage (if any) there is to the head or pistons..

Everyone here has told you to do the opposite of what you just asked. It's for your benefit that you check things out before just doing it and hoping everything will be ok.

alright, next question - how come the crank pulley is so hard to pull off, is there a special way?

A puller...

???

It's a tool

First just take your head off and inspect it. Dont even waste your time and money on a new belt if your head and maybe pistons are fucked. The worst that can happen when putting on a new belt and starting her up is you would hear a bunch of broken shit in your engine and the valves would all snap and you would cause a bunch of internal damage...this is all assuming you time it properly. If you mess up the timing, it'll probably be worse. IMO dont waste money on a new belt before taking off your head and checking for damage. If you did mess up valves or pistons or whatever, just get a new block or swap a whole new motor..my 2 cents

I'd say the opposite. Think about it logically. What's your goal at hand? What's the easiest way to figure it out?

1. You can spend $30 on a new timing belt and put it on. Try to start the car. If it doesn't start...oh well you just wasted a whopping $30.

2. You can pull off the head. Send the head to a machine shop to see if the valves are bent (rarely can you see bent valves w/ the naked eye). you'll have to buy new oil, coolant, head gasket, intake gasket, etc....which will cost you more than the price of just a belt. And you'll actually STILL have to buy a belt anyway.

just put the new belt on, see if it starts. If not, you need a new motor.

i agree you seem like the guy that wouldent care to put the timing belt back on then starting it up. well hopfully anyway. just do it and see. make sure you get the timing right

well think about it. If the motor is fucked up, it's fucked up. Putting a timing belt on it and starting it isn't going to make things any worse. The motor is junk if it hit valves to pistons.
On the other hand, if the motor is good, then it will start.

and you're right. I don't really care about motors that much. Blow it up, put a new one in. I bought my del sol on a wednesday and I blew it up by saturday. i was driving it again monday. Just took the head and put together a new block w/ pieces laying around the garage. I've put 10,000 miles on it since and haven't even changed the oil yet (mobil 1 15k). Motor still purrs. If I blow this one up....cool beans...i've got about 10 other dseries laying around the garage from other people's swaps I can toss in, in no more than 4 hours.

Of course, that is my daily driver. My crx is different. i built that motor from the ground up. i did the build, the wiring, the swap, and the tuning. 700 miles on it now, and I've already changed the oil 4 times. Let me also mention that the car doesn't burn a drop of fucking oil whether it's idling or at 9500 rpms.
I'd also like to mention that the same night I put in my motor in the crx, I had to put a K20 in my friend's EG, the owner of the shop I work at. We put the pistons in that night and were up till 3am putting it in...lol.
i'll also say that we did a 3 way run with his K20 EG and a 12.3 second rotary swapped RWD toyota starlet. Guess who won? The starlet complained of traction problems....I just couldn't see his point when I was still pulling away from him in 3rd, 4th and 5th.

My point? I DONT build cars to lose.

okay...that's enough bedtime stories for tonight.

I follow you.., your logic is definitely right. But man, hes gonna have fun putting on that t-belt. As for the crank bolt..try using air tools...or if you can find some way to slap on a 5 foot cheater bar and jump on it..then you can probably break that bolt. If you wanna keep the crank from moving, just take off the starter and stick a screwdriver in the flywheel's teeth..since you dont really care about the motor anyway. Good luck..try to get your timing right.

you can always just rent the honda crank pulley tool from good ol' autoblown.
Look at all modern honda crank pulley's they have Hex design in the center of them. They didn't just design that for people with hex shaped dicks to play with.
I'm not sure when exactly they started doing it but 92+ vehicles have it for sure. And I know some 88-91's have it, just not sure what year they started.

as long as you have the right tools and knowledge, it is always easier installing a timing belt than removing a cylinder head and reinstalling one. Think about it. You have to remove the crank pulley and timing belt covers as well as the valve cover to do the timing belt. You have to remove the head, intake manifold, rear intake manifold bracket, drain the motor, etc to take off the head. That's the easy part. You'll have to clean your cylinders and and clean the head and block to put on the new head gasket.

And guess what? After doing ALL that work, and everything checks out good...you STILL have to put on the timing belt....lol. There's no way around it; whatever he decides, he HAS to install a new tiiming belt. So skip all the head removal trouble and skip straight to the last step...the timing belt.

am i right?

cant wait till i owne a shop/work at one. i would die for a job like that want to learn as much as possible. about handas anyway. i got that popular swap book. it is very helpfull/educating in the honda/acura world. i love it. its like my bible

I had that book.
But, there is no replacement for hands-on experience. My buddy who just received an automotive degree at a 2 year tech school is having me build his motor.
yah great...he learned how to chang spark plugs and starters...as well as a little internal combustion theory. 30k later...he still doesn't know how to assemble an engine. But guess what? He's ASE certified...I'm not. That's the difference. He paid for his knowledge...I earned it.

huh seems like there is no point to that school thing then. but i myself do like the hands on experience. the book just helps with the unknown things i havent learned yet. i got the basic idea of builting a motor from taking my old dx one apart just to do it and learn. thats why i did my own swap. you can make lots of money from this now days and its really close to the greatest that in the world to me right now.

I absolutely love cars man. It's my sanity. If i'm not hittin my girl, I'm in the garage wrenching away on a honda motor. I'll Roll "H" till I die. I've got the CRX, the Del sol, and I'm buying a CBR 600 by the end of the summer. i plan on selling the del sol for an rsx type-s next year...and within 3 years, getting an s2000.

Then I'll have everything. The crx for racing. The rsx as the daily driver. and the s2000 as the weekend cruise ride. The bike will just be for having fun in the summer.

yeah. i see. sounds like you got everything i want in the future. cant wait till someone comes up to me and says can you help me with my swap. that will be the day but till then i will halp who i can on what i can right here on af or honda-tech to.

fucking showoff bastard

I plan on running honda if at all possible. I currently own a 88 Hatch DX, a 90 4Dr EX, a 89 Accord LXi, and I'm picking up a 93 Civic Coupe DX (I think). My goal is to own one of each of the 4th gens - so all I have left is the CRX and the Wagon. They are fun, reliable, easy to fix/upgrade and for the most part stylish or at least can be. Plus they hold their value and get good gas mileage even with engine mods. Honda for life!

who bambam. yeah you are kinda cocky, but hey if you got the fast car why not. j/k

Honda for life!


WORD!!!
