More specifically a 09 Vibe / Matrix 1.8. YouTube was no help.
Yes, that is part of the plastic guide sitting between the cams. Are the marks on the cams supposed to correspond to the paint marks on the chain? In the picture, the crank pulley is lined up to the "0" timing mark.
Trying to determine if this engine is borked?
TIA.
Same as 1.8L Corolla engine of same vintage. I would think the internet would be deep with Corolla information.
To go off of the painted links, you need to take the chain off and reset it. The thing is, if the crank sprocket has, say, 20 teeth, and the chain is 154 links long, the chain is only going to "line up" once every eleventy thousand revolutions.
What you CAN do is find out which links are supposed to line up with what (I am assuming the hash mark on the outer diameter of the sprocket hub, and inline with the single link and between the double link?) and count back to see if one or the other is a tooth off. Which one is a tooth off relative to the crank will still require that you take the timing cover off so you can see the crank sprocket, at which point you may as well pull the chain off anyway.
If that is a 1ZZ engine, the timing cover is probably leaking at the back by the deck, anyway. I have not seen a 1ZZ where the head and block were machined flush with each other at the deck, and they always develop an oil leak there as a result.
In reply to John Welsh :
Yes, but not very useful. Toyota doesn't bother giving you cam marks like Honda or Mazda does at least nothing obvious.
