No there should be no reason to remove the sprocket, when fitting the chain.

You say there should be no reason to remove it.

I just checked the instructions for doing this chain. They state that you should remove the cam pulleys.
They also clearly show that the inlet is variable.

OP, do you not think you have had enough bad advice in this thread already?

I have car which is not working a potential bill of 1300 or higher and trying to figure out the best out of this mess.

Still convinced Nationwide Autocentre don't know what they are doing and there was nothing wrong with my "Sprocket-camshaft, intake"

Do you think they needed to remove the Sprocket-camshaft, intake ?
Even if the answer is YES, as I said before still think my part was working fine.

They called a mechanic from Honda garage to put it back! If it was "ceased up", the Honda mechanic would be able to sort it out.

Do you have link to replacing a timing chain, all I can find is this:

Thanks in advance.

You left your car into a garage to have a job done they stripped down the engine and told you that another component needed to be replaced.

The garage gave you a quote on the extra part needed you gave them the go ahead to order that part.

You then came on here and got advice from people who probably never looked under the bonnet of a car never mind got their hands dirty and you are going back and forth to either the mechanic or the service manager telling them how to do their job.

Not trying to have a go but the job is hard enough without having to deal with armchair mechanics.

Now if I was doing this job and I found the hub seized I would not even think about freeing it up and putting it back in.

The reason for that is if something happens the hub down the line your engine is scrap and you would be back to me saying I fu**ed up your engine and you want it sorted.

My advice let them do what you left your car in to them to do and fix it.

Mr.Diagnostic · 10-09-2009 10:42pm

I am not familiar with this particular engine but the instructions I have state the pulleys should be removed and I have no reason to doubt that.

I have no idea if the part was needed or not, no more than you do or anyone on boards. It seems to me that the situation has been complicated because you acted on incorrect advice you got here. Its unfortunate but its of your own making to at least some extent and you have to deal with it. Its not an easy situation to sort out.

One thing that I think is very wrong is how you keep naming the garage. I think you should wait until you know they wronged you before doing that. Your gut feeling is not enough.

You could ask the garage if they would allow you bring someone to inspect the car. If so, then find someone to look at it.
You could go with your gut that there is nothing wrong with the part and get them to finish the job with the old part then get it looked at later. If they were wrong then you would have to deal with them.
You could tow it out now and get someone to look at it.
The old part is your property. If it is still out of the car you could go and collect it then get someone to inspect it for you.

I can’t give a link to the info I mentioned as it is not available for public access but if you tell me what info you are looking for I will post up or send you a screenshot.

If you need advice on anything, professional is always best. That is what you should seek. There again, I am just another stranger on the internet

In that case, I don't understand why the Nationwide Autocentre decided to remove it.

What are Nationwide Autocentre exactly? Their website looks like they are a chain of garages in the UK that are not marque specific?

They are UK not market specific, people often used them for MOTs & services.
Only used them because theAA recommended them, eventhough their quote wasn't the cheapest.
I didn't know the 2 companies were linked till now.

I've just checked.

The instructions that I got on how to remove the VVT hub from the cam were to apply air pressure (I can't remember if it was 3 or 30 bar) to the VVT oil inlet (the VVT in the VVT hub works off oil pressure) and "wiggle/twist/turn" the cam, and when you here a "click" it can be pulled free. I was also told that it's very fragile and if pressure is needed, a tap from a plastic hammer only.....

I was also asked why was I taking it off? Was I changing the inlet cam or something?

It's just a piece of info for you.

I think you misunderstood whoever gave you the instructions. Air pressure is required to move the VVT into position not to actually remove it. OP posted that the garage reported it was seized. If they were to follow correct procedure to remove it they would have discovered this at this stage of the job.

It may be possible to do the job without removing the VVT but if the factory procedure states it should be removed then that is the correct way. I don’t think you can fault the garage for that.

It's a lesson for me, I'll pay for the part and will never use the garage again.
But if my old part is OK I'd like to put it back. The garage at the moment are refusing to let me have the part so that I can take it to a Nissan to verify if it's defective.

Just a matter of interest if this part ceased up, what affect would it have on the car?

I'm really puzzled now.
I asked for my old part so that I can get Nissan to verify if it was faulty.
All of the sudden now the garage are saying they're putting the old one back and they will not be charging me for the one that they ordered on my behalf!

Well, the contributions that you have made to discussions here in the past were usually correct. I want to see first did I hear him wrong, or second, did I get duff info.

Gererally you've spoken sense here and based on previous contributions from you, I believe you.

At the moment, my source is not answering his phone.....

What's the correct procedure for fitting a "Sprocket-camshaft, intake" ?
Mechanic is saying if 3 teeth out, it doesn't lock.
But if he follows the Nissan's instructions it does lockup.
Does this make sense to anyone?

Really would like to hear from you regarding the correct procedure to fit a Nissan Almera "Sprocket-camshaft, intake"
Any links, instructions or screen shots are welcome.

Thanks in advance.

It seems to me that there are far too many unknowns to comment accurately. I suspect there is a lot more going on behind the scenes than is being posted here. Did the garage attempt to refit a part that they diagnosed as faulty because you told them to?

You posted that the garage was fitting the old part. Then you posted that the old part is not working as it should. Now you want instruction on how to fit the part.

You seem to be forming opinions based on a lack of knowledge and on poor advice. If you expressed these opinions to the garage then you have complicated matters greatly.

I will stick with the advice I gave you earlier. The old part is your property. Go to the garage and collect it. Do not leave without it. Find someone to look at it and tell you if it is faulty or not. Also find out if it is worn or damaged. Then you will know how to proceed.

Frankly, I don't know if it was faulty or not. Few things made suspicious that the garage wasn't sure either, but they decided to tell me it was faulty because it is easy for them to do so.
As soon as I asked them to let me have the part so that I can take it to Nissan to inspect it, they decided they were putting it back!!

My gut feeling, the part is not faulty and they don't know how to put it back.
That's why wanted to know if "the 3 teeth" thing made a sense to you.
They are waiting for their senior technician to come next week to tell them if the part is faulty or if they are putting it back incorrectly.

Thanks.

That, if true, could nean that it is faulty. Equally it could mean that it has been put together wrongly.

Did they actually tell you this or is this the impression you got from something they said? If they told you this then that looks bad for them.

As an aside, is this your regular garage? If not, do you have a regular garage?

I'm 99.9% sure the European vesion of the 1.5 engine hasn't got VVT.

There are two types of that engine.

The GA16DE which does not have VVL and the SR16VE which is the variable valve version.

Almeras have the GA16DE engine without VVL.

The engine codes you mention would be for 1.6’s, right?

The OP’s car is a 1.5……

Was there ever an SR16? Not sure, but I think the only SR was a 2 litre.

A quick google shows that's in the 1-99 Sentra, 95-98 200SX, 91-93 NX1600. Almera has a 1.5 litre engine.

I've never seen the 96bhp version of the Almera engine, it may have variable something, but on face value the figures suggest it doesn't. The 88bhp definitely doesn't (we had one for 3 years).

OP, no-one on here has experience of, or knows your engine. It sounds like the garage that you brought it to may not know it either.

Bring it to a Nissan garage or specialist.

That's what they mechanic said to me, almost word for word.
3 teeth out and it doesn't lock but if he follows Nissan instructions it does lock.
And that They are waiting for their senior technician to come on Monday or Tuesday to have a look at it and determine if the part is faulty or
if they are putting it back the wrong way. Meanwhile I'm stranded without a car.
I think it's appauling they made me order a part which costs £830 when they weren't sure it was faulty.

As an aside, is this your regular garage? If not, do you have a regular garage?

No, don't have a regular garage really.

I'll see if I can determine the car engine type.
All I know at this moment that it's a Nissan Almera Engine Size:1.5 Year:2003.

I think I might have to end up taking the car to a Nissan specialist.

Garage contacted me and said car is now ready for me!
Their senior engineer discovered they were aligning it with the wrong sprocket or something like that.
I'm picking it up later, so will give an update then.
