My daughter's car's Timing Belt Broke this morning(she thinks) and we are deciding whether to fix it or get rid of it.
YOU CAN TRY IF YOU WANT TO !!!!!!!
:P
“Put a belt on it yourself and see if it runs.”
I think that is bad advise. If there are bent valves, it my run awhile and then swallow a valve. Then you have scrapped the engine without question.
Pull the head and send it through the machine shop to be checked.
“My friends owe big bucks on and spend big money fixing their computer-controlled oh so averaga-looking high dollar disposables, “
Exactly. Mine are paid for, and as I turn them into high dollar collectibles, every dollar in gets at least a dollar in value. Plus our cars don’t depreciate
Plus they are fun as hell to drive. Ooooh, jaguar. Always had a lust for the Es.
You have to shut it off first. ;)
Yeah, I’m old school so I’ve seen it all too. Water injection, magnets, electric supercharger.
The big fuel mileage gain is swapping the old 2 speed power glide for a 700r4 4 speed automatic. Multiple spark discharge helps and you can always swap up to fuel injection with new computer systems.
absolutely
The vehicle has an interference engine. When the belt broke, the valves bent and the engine needs repairs that exceed the value of the car.
Sell it as a parts car, you can get at least $200 and use that money towards something else.
Do not spend another penny on that vehicle.
Little if any money is made selling cars, service and parts does.
I will never knowingly have one with a belt.
Its interference engine, which it almost certainly is, the likelihood that the entire top end of the engine was destroyed when the belt broke is next to nil. To fix it you will need to do a lot more work than just replace the timing belt.. end of the day unless you got INCREDIBLY lucky, you are looking at probably multiple thousands of dollars to fix the car.
This particular car has a timing belt replacement recommendation at 60k, most folks are completely unaware of this, so they wind up like your car, with it failing and destroying the engine. The old KIA rio’s had the same recommendations... as long as you knew about it and replaced the belt the car will keep running, but if you don’t its going to fail and take out the top of your engine with it.
Little help to you now I know, but I doubt you are going to get away with saving this car.
Advertise it cheap. Sell it to the hipster/redneck-looking dude who comes to look at it.
Before variable valve timing a Toyota could upchuck the timing belt with no engine damage. 100k service life, and far cheaper to fix than chain drive DOHC. VVTi engines wreck themselves when the belt gives out.
A leaking timing cover on a newer Camry V-6 costs over two grand. The T-belt V-6 with everything under the cover, about a grand. I prefer the belt.
That’s not the problem, the problem is simply this, most folks don’t read their manuals and are unaware. This engine has a belt inspection recommendation of 30k and replacement of 60k... if you don’t bother replacing the belt, and drive it past that 60k its going to fail, not an if, just a when... and when it does, the top of the engine is done.
People buying these types of cars, are largely ignorant of the maintenance of this, unlike in the old days when timing belts were chains, and engines were designed not to destroy themselves in the event the timing belt/chain failed, todays engines are just smaller and trying to get more out of less. Any interference engine has this liability, if the timing belt breaks or fails you are going to destroy the engine. Junk yards are littered with these cheap small cars because of this, most of them have nearly everything perfect on them, but have a completely destroyed engine.
Sadly these cars sell cheap, but the belt replacement is not, the parts aren’t too bad, but its all labor... probably $500 ish or more depending on where you live to get one replaced, which is a big repair for most people, and they either are completely unaware they need to do it, or are ignorant of the consequences if they fail to.
I have a 2005 kia Rio with nearly 100k on it, its one of the few you will see with that many miles, because most folks were unaware or failed to replace the belts when the cars hit 60k. Mine was replaced at that point and is still running strong, and the other belts in the engine self shredded (alternator/fan) right around 64k... so if I had not replaced the timing belt when I did, I am sure my car would have been in the junk yard, as it belt would have failed. Fortunately those other belts are cheap and easy to get to and replace and don’t destroy the engine if they fail.
Is this a trick question?

It isn’t variable valve timing, its the basics of a interference engine design.
If you have a non interference engine the piston when fully extended will not hit the valves even if they are open.. so a timing belt failure does no damage.
In an interference engine, the piston will collide with an open valve. As long as the timing is kept in sync, the two parts will never be in the same place at the same time, but when it fails, CRUNCH.
Variable valve timing has nothing to do with the issue, you can have variable valve timing on a non interference engine and you won’t destroy the engine if the timing belt fails.
Chains are not foolproof. I was returning home from the field with our Massey Harris 26 combine when the engine quit and wouldn’t start. Didn’t fire once. It had a 4 cylinder Chrysler engine. I described the symptoms to my father and he said, “It’s the timing chain. It probably jumped a cog.” He replaced the chain & the engine ran for us as long as we had the machine.
Someone else over-revved an engine with a timing belt during the early 1980s, broke the belt and bent valves. It was easy for me to fix, and cheap. Not bad at all after earlier experiences of adjusting valves on flathead V-8s, changing kingpins in ‘50s trucks and the like.
Tell you what’s really fun (irony)—laying out and fitting suspension and front end attachment points on a home-designed chrome-moly chassis (not to mention bending and welding the tubing before that). But open source design vehicles are probably the future, so many others are now sharing in the R&D frustrations.
After further review I have another option. Pull the plugs and look at the valves with one of these:
