Need Help
So my timing belt on my 98 Sienna broke at a slow speed and I’ve slowly been DIY with the help of Siennachat and YouTube videos being that it’s a non interference engine also referred to as free wheeling, I’m not expecting any serious issues but if you look at my photo, as well.as the first photo looks like the same situation, the lower teeth of the teeth of the crank don’t appear geared with upper teeth the timing marks are there but it looks like the upper gear is missing, as you can see in a photo of the lower cover part of the belt was wound several times behind the lower cover and tore up the lower timing cover the balancer was not damaged, could it have been damaged like the crankshaft itself, when the belt broke, or is it possible I have a replaced after market block that it was already missing before the belt broke? Is this gear that’s missing part of the block and I have to replace the block now, or is the crankshaft that needs to be replaced? Either way I’m screwed. I hope that’s not the case. The last Second to last photo is what it should look like
