DIY: Motor work, Timing tensioner or anything with the motor and front end

**Charles.waite** · 06-21-2019 07:41 PM

Nope. The oil pump can be linked up at any timing. You’re just fine.

After many rotations i was able to get to this point, looks like chain is off by one on all of the sprockets but locations of gears looks good, I could try to do one more cycle and see if the marked links will match with gears, can anyone please confirm timing, BIG THANKS IMG_0905.jpg IMG_0906.jpg IMG_0907.JPG IMG_0908.jpg

Snakeman, I can't tell about your timing from those pics. Are you about to close this up? Cause all I see is a tensioner that's extended quite a way, and a bunch of old guides and, I assume, the original chain that's obviously stretched. I wouldn't think you'd be asking about timing till you put new parts in.

I see why you think it's off a tooth, I think. And I'm sure that has to do with the stretched chain...and even the worn guides.

**Snakeman** · 06-22-2019 06:31 AM

Yes I’m about to put new parts,

Hope those are better, just to verify timing before replacement

You timing is good. If it had skipped some teeth you’d know it. If it didn’t don’t doubt the factory timing.

**Snakeman** · 06-22-2019 08:17 AM

Thanks, and one more question, where can i buy oil screen (mesh) please don’t tell that i have to buy whole cam bridge

**Charles.waite** · 06-22-2019 08:50 AM

Hah. Well then I won’t tell you you have to buy the whole thing...

You can’t buy replacement mesh pieces. Many people just pop the mesh out and reinstall the cam bridge without it.

**Theiceman** · 06-22-2019 08:54 AM

think about it, everything is "off" by one coloured link the same way , the car is in perfect time. Imagine if you could move the entire chain over one link without moving any of the sprockets. its only the coloured links that are throwing you off. Remember they are only used to install the cam timing in the right location , after that it means nothing.
I would say 80 % of us rip out the screen , remove the pieces and reinstall the bracket. The other 20% buy a new bracket. the important thing Is finding the piece that broke off, it is usually resting against the channel into the head when you remove the bracket.

**Snakeman** · 06-22-2019 08:58 AM

I found whole broken piece

Yea I’d prefer to run nothing over that part.

Edit: actually, on second thought there’s probably no larger of a risk of these ones blowing out tha n the OEM ones. Considering mine was popped out at 65k I can’t imagine these are any worse quality....

me too, but I posted the mesh in the main forum as many people seem to look for it.

I finally received all my parts from ECS. A few thoughts:
1. since I’m doing my timing chain, water pump and valve cover, is there an optimal order to do these jobs? I’m thinking water pump first, valve cover second, timing chain last.
2. I’ve read multiple posts that say no need to lock the cams when taking off the valve cover, is this true? I was under the assumption they had to be locked with the special tools.
3. Should I also replace the fuel pump cam follower since I’ll have the HPFP off?
4. I can’t seem to find the part number for the o-ring/gasket that you find in the camshaft bracket that seals the camshaft adjuster magnet.
5. Is it necessary to change the o-ring for the dipstick tube?

I did not lock the cams with the valve cover off. If the chain is still on it won't go anywhere. I did the hpfp cam follower while I had that stuff off but evidently didn't need to. The kind with the bearing is good, the non bearing isn't, but I didn't want to miss the opportunity to do it while that was all off.

Started taking everything off the front tonight. Actually pretty easy so far, except I broke the driver side lower clip that the condenser clips into. Also found oil coming out of the drivers side intercooler pipe.

There's always some oil there. I try to drain it every time I change the oil.

Audis have had oily intercoolers since forever. Wet PCV systems. If you ever want to get it out without disassembly, you'd have to spray intake cleaners in somewhere after the MAF and drive around and spray again. That will thin out the sludge and the gel-like consistency of a large portion of deposits. There were some who used to pour gasoline innthe IC and swish it around back innthe day.

**Theiceman** · 06-28-2019 07:10 AM

I did an entire build and never used cam locks once

I feel like an idiot right now...... I can’t seem to get the fan connector off! I slide the red tab back but then it won’t come off. I’ve pushed and pulled and wiggled. IMG_0989.JPG

****EDIT****
Just got it off. Turns out there was so much dirt in between the connectors it was basically fused together. I took a can of air and blew in around the connector and then took a tiny flathead and worked my way around it. When it finally came off dirt was falling out of the connector. Damn......

I’m trying to set my timing before I disassemble and replace everything. I’ve rotated and lined up TDC 3 times, but the balancer chain will not line up. Do I need to line up the balancer chain before I replace parts? Or can I leave it as is and line up the chain links on the balancer chain when I put it all back together? If I do it after then I’m assuming I have to rotate the two upper balancing sprockets by hand to get them to line up. IMG_1019.JPG IMG_1021.jpg

**Theiceman** · 07-03-2019 08:29 PM

Yeah do it all after, they spin easy
Lining them up can be a bit tricky so if you are not sure ask, the drivers side balance shift is on a second sprocket so getting that set up right is crucial. It is not difficult but it is easy to make a mistake

Trying to line balancing chain up and have a question, if I keep the drivers side sprocket aligned
IMG_1030.jpg
The chain in the crank sprocket is off by one link
IMG_1028.jpg
If I rotate the two upper sprockets I can line everything up correctly
IMG_1029.jpg
Is it ok to rotate the two upper sprockets by one link to align on the crank sprocket correctly?

I have a set of Craftsman 14-17 open end wrenches and went out and bought a set of Husky 14-17 wrenches... none of which fit the exhaust cam. I am attempting to rotate it slightly to lock it up. I can’t seem to find a tool that fits the notch behind the sprocket. Anyone have any tips?

Also... what size is the balance chain tensioner?

Can't remember what size I used but i have a full set of craftsman. It doesn't have to be exact. You are only moving it slightly

Right... problem is both sets are too thick to fit. I’m on my way to Northern Tool to see if I can find a thin set. Also taking the balance chain tensioner with me to fit a socket on it. Biggest size I currently have is a 24mm and it’s too small. Wish me luck! Thank you gentlemen!

i think thats a 27mm

oops sorry i didnt see your update .. yes that upper balance shaft guide throws a lot of people off, i somehow ordered the right one .. but i did order the wrong guide between the two camshafts for the timing chain, its always something.
work doesnt have to stop , you have a lot of cleaning and prep work to do before the install of new parts :)

I’ve spent more time cleaning than actually wrenching! My oil leaks were horrendous! I was leaking from valve cover seal, vacuum pump, upper and lower timing chain covers. So much grime and oil built up I went through 4 cans of cleaner and degreaser.

Damn it Eric, I've done that but can't remember. Thought my manual would help but nope. It's right in that range though. I seem to remember it needs to be kind of a thin wrench.

Wouldn't be the first time I've used an American wrench that was close.

**Snakeman** · 07-04-2019 09:39 AM

I don’t have notches on exhaust cam, i used tool with prongs (found something in my shop) i think you can borrow some tools from your local parts store

I found a set of Klutch wrenches at northern tool that we’re thinner. (15mm fit)

Not by much, but it made the difference! Thank god!

Also, balancer chain is a 27mm for anyone else referencing this thread. Now hopefully I can button this all up!
