Camera tightening torque

Hey friend, thanks a lot...yes, mine does have a tensioner, it's exactly like the picture...I never would have imagined they were like that. Now I can put my car back together, although my torque wrench isn't in degrees but in pounds, I'll figure it out. Thanks again!

Don't worry about it. If you don't want to buy a timing gauge, just stand straight in front of the cylinder head and hold the wrench horizontally. Imagine a circle; the angle to your body is 90 degrees. It's easy. Pay attention to the timing marks, because I'm not sure how it is in Mexico, but here in Chile, the pulley marks (those little lines) are aligned with each other, and the crankshaft mark, which points downwards, aligns with a mark on the cylinder head or block. However you assemble it, give it a quick turn by hand before starting it to make sure it doesn't seize.

Hi kikemec, thanks for the comment. I was planning to do it that way because torque wrenches are really expensive here—well, EVERYTHING is expensive here... I had them facing each other and the engine seized, but I put the crankshaft torque wrench facing upwards, not downwards. That's why I posted in this forum because I didn't know the other way they should go, but thanks for the suggestion, I'll keep it in mind!

Well, thanks again to everyone who was interested in my problem, and sorry for the delay in responding. I'm happy to report that I was able to fix my Optra, but the timing marks weren't aligned in any of the three ways you kindly suggested. The camshaft pulley marks were opposite each other, just as kikemec said, that is, the intake marks at 90 degrees and the exhaust marks at 270 degrees (clockwise), but the damper timing mark wasn't pointing up or down; it was at about 45 degrees. Once the marks were in place, I rotated the engine by hand (thanks kikemec for that tip ) until I completed a full cycle and noted which pistons were on the intake and exhaust strokes, which ones would ignite and which ones were exhausting, up to a firing order that, if I remember correctly, was 1-4-3-2 (I'm not entirely sure if this is the correct ratio). So I put everything back together using the torque specs pineda87 gave me (thanks for the tip, mate!), put in a new battery, and started it up. The strange thing is that for two days, when it got hot, the oil light would come on, but then it went away. I put in WD-40 semi-synthetic oil. The Hold light was also flashing, but that stopped too, although I don't know if the problem will come back because I don't think it's related to what I did. Thanks, guys!

I'm glad you solved the problem. If the lights don't come back on, you shouldn't have any more problems. Sometimes disconnecting things so much can cause the ground wires to get a little dirty, but it's nothing serious. Good luck.
