Which valves open when? did I bend valves?

I was doing the timing earlier and I think I may have messed up pretty bad. I was having issues with the tension at first, and when I was trying to move the cams closer in, the intake side camshaft went 3-5 teeth counterclockwise from being inline :ohdamn: I didn't see exactly since I moved back quickly but I'm pissed at myself for that :notgood:

I didn't feel really anything hard hit anything, but I'm not sure and I've been looking for the valve opening pattern but not sure what to look for. This was with the crank set at TDC, number 1 was confirmed with a long screwdriver earlier. I understand it moved oposite of where it was supposed to so what are the chances I bent something? :confused: :confused:

This is a 2G head and a 6 bolt block if it matters.
 
What were you turning it with? A combination wrench or a 3/8" drive ratchet? Even with a 1/2" breaker bar you would have had to really turn it hard and feel it doing something bad before you could have damaged something.

There are larger valve reliefs cut into the pistons on the intake side, especially on aftermarket pistons.

I'd try not to worry about it too much, but it sounds like that ship has sailed...
 
sounds like he was turning the cam gears by hand. People don't usually adjust timing gears/belt with the engine running..

I was thinking he had finished the timing belt install.turned the motor,then noticed teeth were off,my wording must have confused you and I dont think people ever adjust timing gears/belt with the engine running..

Using 2 regular 17mm wrenches, the closed end sides. I was basically holding them lined up but seeing if it was actually closer inwards, pushing the exhaust cam clockwise and the intake cam counter clockwise.

It was like the intake cam just wanted to jump after getting pushed out of line, I really didn't feel anything other then it jumping out of place and me pulling it back right after, felt like it bounced with the spring really. I just don't know if I did anything.

so what intake valves would be open 1/4 camshaft turn before the cams are lined up for TDC?
 
Not sure of the valve timing events. I'm pretty sure it was just valve spring pressure you were fighting against. You couldn't bend a valve with a 17mm wrench unless you are a huge guy and deliberately trying! Even then it woul be quite difficult since there's not a lot of leverage.
