[quote=”EricTheCarGuy” post=98308]I think the pic of the spark plug is most telling. Looks like something got down into that cylinder. If that’s the case, you’re in for a rebuild or replacement of the engine.
Keep us posted.[/quote]
Two out of the 4 were smashed, one was just bent and the 4th was just fine. I read somewhere that on some cars you can over torque the plug and it will sit too low? Resulting in contact. But I have a feeling that would be too good to be true in this case.. Looks as if I will be taking more off this weekend.
[quote=”EricTheCarGuy” post=97933]Likely no damage to the engine since the belt is still technically intact. It would be good to find the cause of that issue however. I’d be checking the tensioner. I’d also check to see if the retainers are in place. I don’t know for sure but I think there’s one that’s suppose to locate the belt on the crank.[/quote]
SO.. Pretty bad.
We had to remove the old timing belt it was due to the tensioner pulley giving out. It took out the smaller inner timing belt as well, the brand new crankshaft position sensor we just put in at the start of this mess, along with the crank sensor plate. We changed out the water pump while we were at it, figured may as well while we are changing the belt. Trying to align the crankshaft was not working so I removed the valve cover and I saw some ugly stuff. ALL of the rocker arms had come flying off when the belt slipped. They just seem to sit on top and are held in place by the CAM. After removing the cams, placing all the arms back, I removed the spark plugs… and they were all smashed in, this I have NO clue how that can happen. I tried turning his car over to get the crankshaft realigned because I couldnt turn it by hand, it turned over full revolution and was able to be realigned without any strange noises. But I am still alarmed and want to see what I should check before we put the car back together and try and start it up.

[quote=”KingMeander” post=97541]If I recall correctly, this engine is an interference engine. If your timing belt broke, then you wouldn’t be able to turn your engine won’t be turning over with a “whirring” noise. Someone else may want to chime in.[/quote]

So for some reason the timing belt slipped forward, then a thin sliver came off and wound around the crank shaft pulley and tore apart the belt. The belt did not snap but I am not sure how much damage could have been done here. We bought a new tensioner set and a new belt. How can I prevent this from happening again?

I am going to have to do some more poking around. This car really has been one thing after another. I get it on the road for about 48 hours before something else breaks. Started all with a transmission speed sensor.

[quote=”EricTheCarGuy” post=97048]Sounds like you’re making progress. I cover alternator testing as well as solving electrical issues like this in this article.

Would a timing belt break leave the car making a “whiring” noise? The car is attempting to turn over I can hear the pulleys turn but it sounds kind of hollow and just wont do anything. I assume it had to be something bad to make the car just shut off. But the electrical power never went off.

Omg… So we switch out the alternator start it up. Perfect, take it out for a few mile drive and it ran better than it’s ever. The next my friends wife is driving and the car just died. She said she heard a “clank” and the car shut off and it won’t turn over. Has power all electronics work but it’s making a strange sound when trying to start. It’s an almost winding sound as it tries to turn over.

[quote=”EricTheCarGuy” post=96801]You always start with the battery when you have an electrical problem. Just as it says in the article I posted for you. That said, you may not be able to swap one battery for another. Batteries are designed to work with the vehicle. If you put in the wrong battery, it’s the same as having a bad battery. The battery is the alpha and the omega of the electrical system. If it’s not right, nothing is right.[/quote]
So we took the battery to be tested, was putting out 11.9v but was taking 0% charge so thankfully the guy at the store was honest when he noticed the warranty sticker was still good for walmart. we took the battery there and got it swapped for free and even got $12 core charge back. But bad news, was not the underline problem. I work for Toyota but in sales, so I called down to our service dept and we had the car looked at. Was the alternator, spitting correct volts zero amps. So I will be swapping that out this weekend. The wonderful discount the provided was $500… yeah. No, I will swap it out for the cost of a pizza and six pack. So I will keep posted if this solves the problem.
Question, can a bad alternator trigger a misfire?

Took the battery to be tested. Was holding 0% charge and the guy at the store noticed the warranty sticker for Walmart and told us to go see if we can get a new one. So good news we got a free replacement. Bad news. Charging system light stayed on car was running at 11.9v after we turned it on. So back to could it be the alternator or the computer? We cleaned the terminals but they didn’t look nasty. Still same issues. I’m stumped.
