- Alright, more progress on the 1991 Audi 90 20v quattro sport! while it was running and driving the timing belt was at least 15 years old! not something that I would trust, my philosophy is that if you're not 100% sure that its been changed in less than 90 thousand miles, just replace it. These 20v motors are all interference, meaning if that belt snaps, you're going to be smacking pistons into valves and you're going to need a lot more work than if you had just changed the belt.
I try to give some insight and good instructional video / explanations at critical parts, but isn't a step by step video with torque specs. Feel free to ask any questions below, i'll do my best to answer them. This information crosses over to the 7A and 3B but is also very applicable to the AAN ABY ADU as well as the 10v motor varieties (NG, WX, etc.). The work isn't hard but I try to stress the importance of the timing marks! know what you're getting into before starting!

Thanks for the great video. I was able to change my belt out with no issues!
Awesome! It truly is amazing how nice and original this thing is. Makes working on them so much more enjoyable. Great call out on using the flywheel mark as well, I was waiting for that! At least when changing the strut mounts/bearings you just gotta take off the top portion of the strut and not the whole dang housing, like the B2 cars. Nice stuff!!!
West coast rust free cars ftw! Clean cars are so much more enjoyable to work on, and rewarding when its done! Tried to make this informative but not overly instructive
@@BrokenQuattros its a great mix of both, honestly. I had never seen that little V shaped bracket that lies on the timing belt cover by the snub mount. Always learning something new.
@@michaeljacyno8368 really? Its original, odd ive seen them basically everyone... at the same time i can see how it gets left off when reassembling
@@BrokenQuattros well to be fair, I probably never paid attention in the past, plus the only 5cyl timing belts I've done were on 10v cars.
@@michaeljacyno8368 ive only seen them matter in high HP/high revving situations where having it keeps that belt in place
Nice one! This video will be a big help to many people.
Great stuff, thanks for doing these. You make it look easy!
Been looking forward to this vid man. Glad things are coming along for ya
Are there no flywheel marks as well like the AAN? I remember the 'dot' on my crankshaft pulley was slightly off and it was always nice to re-confirm alignment using the flywheel mark. However, I like the idea of truly checking through the spark plug hole.
There is a line on the flywheel just like aan and other 5 cyls for that matter, its often hard to see, using a welding rod or something down into the cylinder is an accurate way to test.
You mention timing way off. Can 3 teeth off do catastrophic damage? Got offered engine but timing is off that much. Engine out of car. Spinning by hand can't feel any valve knocks. First time doing project on this type engine so wanna check if worth taking risk.
What are you doing with the type85?. Is that sitting in your garage waiting on you getting round to it like mine is?.
Kinda. Its technically a type81 urquattro, we didnt get type85 ur in the usa. Ive been collecting parts to do it proper. Selling this 90 is part of the plan for this URQ, need the money for paint work
@@BrokenQuattros Trying to find parts is the problem, even more so the smoked rear lights that my one has. They are almost made from unobtainium.
Hey, just found this channel. Does anyone have a CQ body for sale?
I'm a newbie on the 20V, but the 10V has the timingmark on the camshaftpulley on the rear side...
Hi. I just replaced the timing belt on my ‘91 QC. All the same way that you did. I tried to start it, without radiators, belts and rest of accessories. It’s cranking but no spark. Do you think that it might be because of the missing signal from some kind of accessory sensor ??
Im assuming it was running prior? The only sensors are dizzy internal hall sender, and crank/flywheel sensors. So as long as those are all hooked up. And the coil is connected to the dizzy, nothing should have changed. Unless you touched one of those components, there is nothing on the front of the 7a engine that makes it run
@@BrokenQuattros Yes it was running. I already checked pin and flywheel sensor, all good. Spark just disappeared. I tried everything. The only part that I didn’t test is ECU.
Love the j dilla
Great job!
What’s this car worth in this kind of condition? I’ve got a guy who has one for $3200 is that a good buy?
Depending on condition, rust, maintenance. It could be a very good buy. If its rusty, no. If it needs thousands in deferred maintenance, but is pristine otherwise, it could still be worth it. Depends on what it really needs.
@@BrokenQuattros This is his post
5 speed 1991 audi cs 90 quattro 20v i5 with 179,xxx miles over good shape for the year and how rare these are. Put quite a bit of parts into this car since buying it last year so quite of bit of fresh parts. Car will come with 2 sets of wheels, one has winter tires that are in good shape and one has older tires that need replacing, car comes with lots of spare parts, as well as factory repair manuals. Since I've had the car it has gotten a new fuel pump, fuel filter, alternator belt, distributor gear, distributor cap, spark plugs, valve cover gasket was replaced recently, car needs headliner but isn't insufferable without it. Overall a solid car that can be driven away and I'd trust it on any long road trip, needs new pads and rotors, but isn drivable. definitely worth saving and restoring to it's former glory. Don't really want to sell but I'm moving and can't keep it. Valves, water pump, and timing belt were also redone within 15k and will provide details and pictures in dm.
@@totalpackagedetailingllc4413 send me a message on instagram, @broken_quattros
Done loads of VAG belts and I’ve never undone the crank pulley bolt yet! Just undo the four cap head screws
On the older 5 Cyl motors, the crank bolt tightens down on the harmonic balancer itself, unlike the 4 bangers where you can leave the crank bolt and remove the balancer.
Nice Job
What is the PN for those suspension parts you have? Are they the top “caps”?
The ones shown are the meyle hd rubber top strut mounts, not the metal caps
@@BrokenQuattros Where did you manage to find those rubber tops, cant find them anywhere
@@willtrautman6243 rubber tops? Are we talking about the strut mounts?
@@BrokenQuattros I'm talking about the rubber that goes between the metal cup on the top of shock tower and the shock tower itself
@@willtrautman6243 so the rear metal caps are covered in rubber, front are not, they have a small hard plastic cover on them from the factory, bits its just a lip. The front need to be able to turn and articulate with the steering
I heard Empi is trying to turn them around.
One can hope, i dont plan on making any purchases from them in the near future
look at the ignition timing because you turn the cam a little bit... I guess its not perfect alligned now... But well explained ;)
Gotta take the camera angle in account. It is set right
@@BrokenQuattros i mean the distributor.. the inlet cam drives the distributor but i think you know all that stuff :D
@@brhc80 ohhhh gotcha, yes
Still want to sell it? I think you gonna search a loooooong time for a Car in this great shape.
"Want" to sell and "need" to sell are different things. Id love to keep it, but i want to paint and finish other projects sooo it becomes a need to sell...
@@BrokenQuattros
Hopefully i dont Need to sell my beloved collection of Junk on four wheels 8), i would rather sell my Hamradio stuff. :D
yupp. ive had the same experience with their stupid kits. they did give me a $25 gift credit when i showed them that the itemized list below all the pictures is not representative of the pictures. but it did take some extra work. very stupid.
More than I got. Ive bought from them 3 or 4 times, i think 1 order didnt have issues
le me watching: oo, a Coupe.
OOOO Coupe quattro O_O
