VW TDI NO-START After Engine Rebuild? (Part 2)

Let's finish up the no-start diagnosis on this 2005 VW Passat TDI with a rebuilt engine.
The PicoScope comes out to play, showing some really neat information on the computer strategy used by VW to fire the fuel direct injectors.
Can we get it running on the trailer NO PARTS REQUIRED?

@@waderigsbee6923 exactly mate. I remember being made to set the valves on a V16 diesel generator when I was a first year apprentice. It ran like a burst bag of bolts. My journey man watched me make the mistakes, them took me through where I'd gone wrong. Always respected that guy for not going off on me. Just pointed out my hiccup and then why things escalated. 👍👍

Too many variables... Great job to Ivan for having the patience to work through all the issues and to show the younger mechanic where he went wrong. This would definitely be a job turned down by many. Thanks for the video!

The next mechanic; “holy moly this cam pulley has 17 painted on timing marks, which one?”

[@georgebeuselinck9255]

When the kid said, "Timing the camshaft is easy." I knew that it was timing. The next clue was the turbo boost gauge mounted on the A pillar. This kid doesn't know how lucky he was to have you diagnose the car.

It's a pleasure to follow along as Ivan forges sure-footedly through a fog of confusing symptoms, painstakingly keeping straight the clues gathered so far, and carefully avoiding jumping to wrong conclusions, ultimately nailing the problem. Well done!

[@PineHollowAutoDiagnostics]

Thanks Graham 🙂

[@Ianf1x]

Having done timing belts on vw/ Audi many times I saw timing was wrong. The tensioner has a pointer that should be over to the right of the window gap on back plate. If I have no start after fuel lines being off to bleed I take of return to filter and suck with vacuum and key on key off 10 times. Great job .

[@Phill22k]

FYI Cam/Crank variance can be checked in live data with the engine running, so little trial and error with the slotted cam gear youll get it bang on. 0 degrees being perfect.

[@michaelh2034]

While zero is perfect in regards to kw, a retard to -2.9 is best for mileage and a slight cam advance to +1.0 is best for throttle response and power.

[@billsmith5166]

He's got guts doing what he did. Great job getting it going for him..

[@mikechiodetti4482]

The picture shows where the cam and timing marks should be for the engine to run.I like the idea of the three bolts fine tune adjusting the cam for a streched belt. Sometimes getting the timing marks just right can be a problem when assembling the engine. Good job Ivan!

[@johnames6430]

That's something that should be noted in a tear down guide like a Haynes manual. I wonder if he used one. A simple mistake like that required him bringing in an expert and hours of time. That's why you should have lots of markers, nail polish in every color, white out, and anything you can think of to mark where everything was before taking it apart.

[@mikem5475]

@@johnames6430 very good technique. I also use colors of nail polish to mark locations of things

[@rkan2]

On a regular time chain replacement interval the time shouldn't change much more than 0.1 degrees so it is really for just setting the fine time of the camshaft - or in the enthusiast space, more like your preference :P

[@kevinmarshall1072]

On this engine you lock the crank & cam in the correct position using the correct locking pins if you have them or by other means such as an appropriate diameter drill bit if you don't, the 3 bolts are not for fine adjustment, they should be left loose whilst tensioning the belt then tightened after. they are just to stop the tensioning process pulling the timing out by a tiny amount when tensioning the belt by allowing the sprocket to move without moving the camshaft. its a common setup on European engines.

[@mikesvirtualgarage9917]

I know your love for VW/Audi is growing, Ivan :). Kudos to the kid who brought the car in. Awesome 2 parter, plus Russian repairs!! :D My weekend is complete.

[@thx1138guy]

I'm always tempted to fast forward to the solution but like to see Ivan troubleshoot it first.

[@stigonutube]

got her in the end, well done Ivan, russian piston to tdc trick always a good place to start when facing the unknown timing belt or chain..

[@Paolo0902]

To set up timing you could use blocking pins (sometimes the drill bits are useful). Also the tensioner - the arrow should point at the middle notch and then the bolt should be tightened. But man you are awesome. Pure logic at best.

[@mmichaeldonavon]

Ivan. I couldn't wait for Part II. :L-) Loved the diag.

Good job Ivan. Starting in after someone else has worked on it. Not knowing if they have pinched a sensor wire or left a ground off. Working around a trailer. Cheers!

[@flightofarrow]

That laugh is what victory sounds like

[@DerGolf2000]

hold your horses....1. there is a bolt missing from the Camshaft timing wheel. 2. The timing is in its outer position, usually not right. 3. If the torsion value in VCDS is more or less than 5 degreased. from 0, the engine will not start.....

[@akhtarkh]

Respect to youngster for taking the initiative to rebuild the engine. Praises for Ivan for excellent diagnostic and analysis. This was a fairly enjoyable and understandable video since I do not have to watch other videos to understand what often used terms like, short term fuel trim, long term fuel trim or lambda means (hint for Ivan, put few words what those terms are when using in a video).

[@PineHollowAutoDiagnostics]

Thank you for the feedback :)

[@dans_Learning_Curve]

Great job! He'll forever remember working with you! Just like you worked with Keith D., and Eric O.! Hindsight is 20-15! Better than perfect vision! That's the whole theme of my small channel.

[@iankelly2110]

Hi Ivan in live data if you look for torsion value it will give you what degree cam is set at A torsion value of "0" is the general consensus for optimal timing. VW spec is +1.0 - +1.5 for the new belt to account for belt stretch and this is what i set everybody's timing belts at every time I change a belt. Every belt I set the torsion value on usually returns better fuel economy than before the change

[@cristianojoana1898]

This was my guess .. this engine if the camshaft sprocket isnt in spec it can get a bad cold start but a good warm start.

[@craighenty]

[@TheBlaert]

I love these engines. My old 2001 Passat has 600k miles on it now. It actually broke the lug off the timing belt tensioner that the little hydraulic ram acts upon. The ram went full extension but pushed on the actual roller part kind of keeping it from going completely slack. Drove for 25 miles like that not knowing what had happened. I was able to pull the belt off the pulleys by hand...That was 360k miles ago and no damage was done

[@lesbender236]

From the very beginning you could see the original bolt marks on the cam pulley were in the center of the slots and the bolts were at the end, so it shows the timing was off to start with, which shows it was done incorrectly from the beginning.

[@craiggoodwin9704]

Reminds me of issues I had on my first engine rebuild. Pretty intense experience starting the first time. Hearing engines fire up the first time after a lot of work is always rewarding and fun! Great job Ivan!. Thanks for Sharing!

Great job, good learning experience for the youngster.

[@stephendee7839]

Way to go! From before you started diagnostics, after hearing that the engine wouldn't start after rebuild and the owner suggesting check the timing, I think that's where I'd have started just to make sure it was configured properly. You got there in the end, but I think that the ecu behaviour, cutting fuel and injector pulses led you down a bit of a rabbit hole that you did great to get out of.

[@PineHollowAutoDiagnostics]

I just wanted to play with the scope and gather data before resetting the timing 😉 wouldn't learn as much if we just fixed the timing in the beginning!

[@THEDRAGONBOOSTER8]

Well done Ivan, I love it ,when a plan comes together. Good on us ..lol

[@rudimaier3679]

holy ivan, that was a real russian roulette on the timing. 😀 you only need to throw a 8mm pin to align the camshaft. and it turns so hard cause these are pumpe düse injectors, driven by the camshaft...

Mechanical Cam timing for a High Pressure Fuel Pump must be right on because the Atomization of the Diesel Fuel is absolutely critical at the precise time in the Power Stroke. I think you are right on Ivan.

Great video! I've had these issues before, look for torsion value in live data should be -1 to +1 in my experience.

[@JustinBarendse]

From South Africa...love your videos. When this series started out I knew immediately the timing was out. Some background on these engines....they are indestructible if serviced as per spec. Oil change every 15000 km, diesel filter every 30000 km and never ever let it run out of diesel as it lubricates the diesel pump and injectors. Expected life span is 500000 km easily. The engines were used in delivery trucks in europe before euro 5 and lately euro 6 emission controls and about 50% of those vans did 1 million miles. It sounds a bit tractor but can do over 100 miles an hour and still (within normal legal road speeds) give you close to 20 km/l. The only engine I think that was better than this engine in small dispalcement diesel engines has to be Isuzu's Y17DT engine.
