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

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 🙂

[@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.

[@billsmith5166]

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

[@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.

[@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 .

[@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..

[@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

[@arthurfricchione8119]

Nice through job of troubleshooting Ivan. No scope nowadays no repair. Thanks for sharing. You and wife stay safe and well 😊

[@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.

[@htwrk2]

Awesome diagnostics! Great workaround to verifyingTDC without having to pull the harmonic balancer.

[@steveharvey1876]

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!

[@thx1138guy]

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

[@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 :)

[@georgebeuselinck951s]

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.

[@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

[@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!

[@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.

[@kevinmartin9432]

Coming up to 50 years as a mechanic, but you are in a class of your own!

[@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.....

[@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.

[@marindamjanic3242]

I have skoda fabia 1.9 sdi(no turbo) only 64 hp,first owner and after 20 years and 260tkm I can say this engine is bulletproof.Put new inserts in injectors on 100tkm and new clutch and that's it.Car is rust free and start's right on,not the case with my Lancia delta 3- 1.6 mtj.

Amazing how incorrect cam timing killed injector pulse! That's the last thing I would have suspected! Great series as usual, Ivan! Fired right up!

[@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.

[@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!

[@alrifainidal]

the customer was sad during the work. but when the car ran he has a big smile. LOL nice work Mate

[@SalimKhan-gk1fh]

Excellent video Ivan! you have to remove that crankshaft pulley where you engage a special tool for TDC alternatively there is a TDC marker in the hole in the bell housing pulley .It ran as sweet as a nut when you had it all timed up I also appreciate you for not calling it a Eurotrash !! them things are a great car and see over 400,000 miles easily

[@darioandrijasevic2804]

Although the problem may seem simple in the end, the depth of the entire diagnostic process and verification that you go through is second to none. Found you years ago from the Nissan CVT and the Hyundai 2.7 video with Eric O., been a subscriber ever since, hoping that in 10 years I might have 50% of your skills and knowledge

Yup, when you said rebuilt motor, I was thinking first thing to check is the basic timing. I have seen some Honda engines with crank/cam set so far off they end up with bent valves. People don't do good research or get in a rush to finish.

[@aldrinalmario1513]

Another awesome diagnosis and fix Ivan! Indeed it somehow seemed out of timing from the first video. VW's strategy for injector function is quite interesting. Was waiting for a view of the battery and if you guys charged it, if not, I'm definitely getting one of those! hahaha.. Cheers!

[@John76546-x]

The BEW TDI will run without the CAM signal. Motor just has to turn twice before starting for computer to know timing for injection. The motor will not run withouth the crank signal. The little window in the CAM, there is a small hole behind it where you ind=sert a pin (drill bit) during timing. The mtion in the cam bolts allows tou to set timing plus or minus 5 degrees.

[@stealthg35infiniti94]

Timing is Everything! I paint both the sprocket and a belt at both the Crank and Cam locations whenever the the timing belt comes off. Just ONE tooth error can ruin your day. It's happened to me.

WOW great follow-up video IVAN.My guess was a fuel pump,way wrong.What a valuable lesson,but it really would be hard to get that far with out a scope,for most of us.HOWEVER you SHOWED it can be done ,in that it was a total mechanical issue.The correlation between crank,cam timing that uses SENSORS to tell the PCM WHEN to open the injectors.I'm surprised the fuel PRESSURE was affected by the valve timing even though it runs off the cam.This is one of your better video's in terms of teaching LOGICAL diagnosis,thanks IVAN

[@kieronhoughton4261]

From my memory, the cam gear elongated bolts are for belt tensioning. That big bolt is the main big boy attaching the gear to the camshaft, those little bolts are there for when you tension the belt it’s evenly applied because the gear will move. As long as it’s not touching either side of the Elongated notches I think it’s fine

[@andrewbancroft6174]

Yes you're right 👍 pin the cam and slacken the bolts so the belt can tension properly especially important on a multicam engine. Although not many people bother. 😕

[@mag1vl]

Great Video Ivan and very interesting also because I have no idea when it comes to diesel engines thanks again and cheers from Australia ;)

[@dazasmit2048]

I think the cam was a bit cranky.

[@johnfountain8143]

Just trying to help .........There is an 8mm (i think ) hole on the camshaft and the head to time the camshaft to TDC .... after with engine running at idle you look at scan tool live data ( measuring block 4 ??? maybe ) and it will give you a crank/cam coloration figure with the engine running .. now with the engine stopped slackening the three 8mm set screws you move the cam shaft independently of the drive wheel. tighten and recheck .... on some VAG diesels this was part of the 25000 mile service

[@bbogdanmircea]

Great find and fix Ivan but please don't mention the high pressure pump anymore, this is a PD, every injector is a Pressure Pump actuated by an additional cam on the camshaft!

[@davidraezer5937]

I would still get the locking tools and perform the procedure to correctly time the camshaft to the sprocket. Might not make much difference in the power delivery but it’s good piece of mind. These lock tools look to be fairly inexpensive compared to some engine lock tools. I have also used Blauparts for timing kits because they have tools to rent for a small fee. Also I believe that is a PD engine and the injectors are driven off of the camshaft.

@@throttlebottle5906 It's called the "Torsion Value" can be adjusted left OR right. It's a PID to evaluate stretch of the cambelt because the injectors are operated by the camshaft it puts extra stress on the belt that you don't get on a standard valve only camshaft.

[@richardcranium5839]

usually diesels with different head gasket thicknesses have nothing to do with timing. injector pump shim or injector adjustment do that. the varying thickmess is to provide the proper piston headspace to allow for crown expansion as the piston heats up

That only affect compression ratio

[@V10PDTDI]

@@cristianojoana1898 yes it does affect compression ratio but if you put the thinest gasket the head will be lower and if you do the opposite the head will be higher so this is why the camshaft sprocket have some adjustment because all the timing components are all the same for all the engines it has to accommodate for different engine cylinder block deck height.

[@michaelh2034]

Using a pico on one of these is like dressing up a pig in a suit. These are very simple engines. If you follow the directions and invest in the proper tools to lock the crank and cam, you should have zero issues. Considering my shop is a TDI speciality shop, I think I have rebuilt a few of these.

Hi Ivan… You can check if the timing is correct by using the scantool - or VCDS - and go into ECM and group 004-4 and read the “torsion value” and it must be near 0˚ KW… KW stands for Kurbelwelle (crankshaft) in german. Unfortunately not every scantool can read the value with crank no start, but only when the engine is running…
