thanks i was looking for info on putting my cams back in the head . i took mine out to change valves and ported the restricted exaust ports out . cant wait to get her together and running . this video was a great help .
It is totally normal. Because of the greater number of links and that number not being a multiple of the number of teeth on the gears, it takes several turns to get the paint marks to line up again. As long as you have 16 links between timing marks, and they both line up with the arrow on the cam caps, your timing is correct. My engine is smooth as butter without so much as a hiccup.
You did it correct, the marking that you make yourself on the chain never lines up learned that on my first a4 build.its not like a Honda when you make the marks the have to line up. The cam holder marking and rear sprocket marks line up you are good.
I was worried about this to but after looking at it again from another point of view whats happening is the tensioners are not primed with oil and what is happening is the bottom guide is seeing the tensions of the valve train then releasing letting the adjuster rock back down as soon as the tensioner is primed it acts as the fluid lock and the variable side of the tensioner
You would crank engine to top dead center, then remove the intake cam, and make sure you have 16 roller nubs between teeth, from cam to cam top. Both cam marks with be off from top center mark (exhaust to Left and intake to right, slightly.) If it's off 1 or 2 teeth you won't have damage. But this engine only has two teeth off capacity before it's an interference damage. That applies to timing belt as well. You will get an over advanced intake came code tho if you are off teeth. So if you aren't getting that code, you might just have worn tensioner guides.
Does anyone know if this is ok if this happens when the head is on the block and the timing is done? Trying to turn my motor over to test it and the tensioner did the same thing as in this video
Was this a new cylinder head that you purchased? or your used one that you had sent off to be cleaned? I had a sludge issue and have yet to have my cams cleaned.Ive tried cleaning them with diesel fuel and it worked just not 100%. clean.
Ok, so basically if i wanted my cams clean right i should disassemble the top part of the engine to send it off to be cleaned? sounds expensive and time consuming
The mark you made will not line up after you start rotating it... thats normal. Basically arythmetic bud. The circumference of the chain and those of the sprockets do not share a geometric relationship of 1 : 1.. What i mean it's let's say after 1 full rev the green mark is out... if you kept going and kept turning it over after say.....12 turns for an example, the green dot would eventually come "full circle " and line back up the way it first did when you assembled.
The only way your green dot would line up with your timing after 1 single rev is if the ratio/relationship of the chain:cam sprockets was 1:1 If it was 2:1, youd have to rotare twice to see ur green mark line back up...3:1, 3.....and if its a decimal like not a round number for ratio, is could take up to 300 rotations to get it to "come around" you see?
I have one these engines in an Audi TT. What a horrible design! They could've just linked the cams together with gears, and they'd have zero problems with tensioner noises and leaks....
These projects have many in-depth tech items. Having oil psi is one of these. Mechanics get a heads up in their shop manuals. navigating for the first time and super focused on timing marks before the big install is a bit overwhelming. So for you idiots and your sarcasm, get lost. You think you're after comments make you look smart??
made sure line up the camshafts with the marks and 16 roller pins from right to left 16 pins o u will vend valves intake it happen to me shit, I HATE WEND IT HAPPENS FUCK,

Mines doing this but ita actually in my car and runs do you have any idea why
You have no oli pressure thats why it does that,
Yep, I definitely got that answer before I put it all back together. Car has run great for the last 6 months or so.

lol, Revelation @ 1.58 can I get a amen.
you have to set it accordingly w daylight savings, fall equinox, etc...
the cam reluctor plate on my 2003 1.8T (which I replaced) stays kind of loose even with bolt tightened; is this normal?
Hi, really useful video - thanks for posting.
Quick q - if you don't have 16 links how do you adjust it?
Thanks.

I don't get it-you lock the crankshaft gear, lock the two camshaft gears-how can it be out of timing?
Ad Mirer
So I rebuilt my head and the marks kind of lined up in the chain has 16 and car barely runs sensor shows me on my code reader cam off bad timing
I'm doing a 1.8t swap on my Jetta and the motor that I got does not have a plug for the chain tensioner will this make a difference will it not run ?
theres more precior or tension in one side they both need to be alined wit the same force
I just looked at an A4 today and the sprockets were bad and it bent all the intake valves.
Compression 120 I'm almost giving up how did yours work out and what was the trick
im working on the same car, it needs oil pressure.
Did you figure this out yet? I'm getting ready to build a 1.8t head and would like to hear why it was doing that.
I beleive that its a lack of hydraulic pressure from the oil pressure
Does anyone know if this is ok if this happens when the head is on the block and the timing is done? Trying to turn my motor over to test it and the tensioner did the same thing as in this video

I had this professionally hot tanked at the time it was milled.

what was the solution? how did you fix the issue?

Thanks for this comment, lost faith in humanity for a second
Look at all these "mechanics" talking about oil pressure... LMFAO!!!
but it's the correct answer... it need oil pressure to keep it tensioned
No oil psi
there's no oil in the tensioner thats normal
made sure line up the camshafts with the marks and 16 roller pins from right to left 16 pins o u will vend valves intake it happen to me shit, I HATE WEND IT HAPPENS FUCK,
there is nothing wrong with this ...
16 links is the magic number you want
7 complete links, 16 rollers
its no good
