Hello @JLL,

Thank you for response.
Well, I'm using dedicated box for this engine, hard to estimate whether they are good quality or not.

As for me - yes. Let's say I've partialy tested the tool.
I've put the locker only from the exhaust side, and tried to move it forward slowly to side of intake crankshaft. It's blocking on middle of the head (which actually prove that the exhaust camshaft is not perfectly aligned). This is not happening on the intake side.

I'll record video today how it looks so maybe it will be easier to understand.

Meanwhile, can those camshafts position be fixed somehow?
I've unlocked the camshaft on the left side for both, set up all the tools, then I've screw both of them while aligned, but still there is a minimum requirement to push the exhaust camshaft to side of front bumper to put the tool.

To be honest, I've found few videos and guides where people say to minimally rotate the camshafts if it's needed to put the tool, but in most of videos they says it should easily go on it position.

Hello @JLL,

Attaching a video just from now. The rotation is just a milimeter.

Can you take a look? What do you think? I've already rotated it many times, always on TDC this behavior is happening.

Hi Guys,

thank you very much for response, appreciate.
From what I've understood this engine is builded the way that if you use all the tools, and follow replacement steps it cannot be off by a tooth.

Why? It doesn't matter how you put the chain because we are loosen the camshafts bolts and they are freely to align (independently to the chain which at this point is already set up).
It's explained here: How-To: Cruze/Sonic 1.4L Turbo LUV/LUJ Timing Adjustment

I think I need to loosen the camshafts again and try to tighten them one more time. Maybe during tightening them and holding the camshaft with second wrench to not let it move I've just used too much power in holding them and accidentally moved it by milimiter.

I'm afraid to unscrew them for the second time, but seems I've no choice.

Hey @JLL,

such a great explanation, thanks for that.
However I still don't fully understand how chain can be off by a tooth.

In documentation, guides, references there is nothing about any specific way of putting the chain.
Isn't it that the chain can be putted in any way, BUT we need to make sure that the camshaft is properly aligned with lockers on it proper position before torquing?

If not, then how can we put the chain correctly on? Even that guide I've posted above doesn't say a word about it.

Hey @JLL,

first of all I really appreciate your time spent on those explanations.
And sorry but this is still not clear to me.

I fully agree with the part of exciter rings, crankshaft, and camshafts.
But the first part I still do not understand.

"You can put the chain on in any way BUT, you have to make sure the chain doesn't shift a tooth when you put tensioner on it. If you have any slack after the tensioner has been released and the upper guide is in place, the chain slipped a tooth, most likely on the crankshaft spocket."

In my case for sure it didn't shift after I've released tensioner, the only way is that I've put it incorrectly from beginning, but we already agreed that it doesn't really matter.
Somehow I believe that during tightening the bolt for exhaust crankshaft I've used too much power to counter tightening and accidentally I've pushed it too far, and in result the locker do not fit just by a milimiter.

Do you think that such scenario is possible? or you are still fully convinced that the chain isn't correctly set up?
Tomorrow I'll try to re-do tightening of the exhaust cranshaft.

As a side note, You did leave the timing tools installed and hold each camshaft still with a wrench while tightening the phaser bolt, right?

Yes, correct.

They do need to be replaced since they are TTY

That's painfull as the price is insane just for two bolts, but seems I've got no choice.

I'll try first with old bolts just to get proof that this is the case and it can be set up correctly, and only then I'll use new bolts.

Thank you very much, I'll come back tomorrow with update - I hope good update.

Hey @JLL,

I think we got this

What do you think about this?

 

[hapvlz]

I've did that during alignment process and for internal test afterwards, indeed didn't do that on video.
I hope this engine will ever start...

Thank you very much @JLL for your advises, explanation and time.
I'll come back here to confirm whether it started or not, probably I'll do it in 2-3 days.

So the day came My car finally started today. I'am still surprised but... it looks fine so far! Works pretty stable, no fault codes, driving acceptable, I would even say it's better than before.
It took longer than I expected, I suppose to start it last week Thursday but when filling coolant, oil cooler started to leak... So I had to wait for additional o-ring between thermostat and oil cooler.

Again, big thank you @JLL, you saved me.
All the best for u!
