Need help timing my lnf

The timing chain should have 3 colored links on it, these correspond to appropriate teeth on the cams and crank gears. Or at least that's how it is on an L61, the LNF should be similar but I can't pull up the service books right now.

You need to make sure it's correct on the crank too though. You have to release the timing chain tensioner and then move the chain to the correct spots. You shouldn't have to remove the gears at all, though removing the guide between the two cams can help position the chain easier.

The gears are only going to go onto the cams in one position, you have to turn the cams to appx the right spot, then put the chain on and line everything up exactly before putting in the tensioner and locking it all in place. It's been a little bit since i've done one but the engine doesn't want to hold the cams perfectly on line, you will have to move them to position and set them while holding a little tension on one of them, I think it's the exhaust. Once all the marks are there, if everything moves back a little before you set the tensioner it's not a problem, just make sure that the marks are all still on time after you get the tensioner installed, and roll the motor over once or twice by hand to make sure everything spins freely (always go clockwise on the crank pulley, never rotate the engine the wrong way, very easy for it to jump timing at this point).

That is making me understand better just turn the cam bolt untill the gear is in right spot with the chain off,
Will the bottom one spin easy and there is not much slack in the chain even with tensioner out, is it the upper chain guide ?

Ok now that sounds bad I can't turn it by hand I haven't tried with the tensioner out would that make it hard to turn the timing chain is still on I had to use w wrench on crank bolt to get it to tdc it was hard

With the chain on you will need a wrench to turn it, he's talking about just the crank without the chain. And even at that, with the balance shafts and water pump there's still some resistance. It should turn smoothly and without any uneven resistance. The cams will be harder to spin as they push the valves down against the spring pressure, so that's normal.

you cant reliably time an LNF without a work shop manuil and the timing chain cam gear holder. You also have to drop the pass side of the engine down, and remove the crank pulley and timing cover. The links match up to the gears, BUT without the tool you wont be able to get them to align. You engage the inlet cam with the link matched to the gear marks ( tool in place, you then engage the chain and colored link to the crank pulley at 5 o clock, and then put the chain on the ex cam ; as you do so the crank will turn to 6 oclock and make you think you are wrong. You are not.
SO: You have:
NO service Manual?
NO service cam gear locking tool?
You have
BIG problem. tears will results and you will become very poor very quickly.

I'm sure the cam gear locking tool would have been real useful though.
