Fantastic video Gary we have been in for a treat without a doubt. I’m 47 years a mechanic and I can see why the parts cannon was fired on this vehicle indeed I probably would have guilty myself but to a lesser extent. Your skill set knowledge and investment in equipment is plain to see ‘ even a good garage with good mechanics can’t really be expected to carry out such in-depth analysis as your self we can’t do it all anymore you sir are indeed a specialist. Have watched the video twice hope there’s a part 2
I very much agree Kevin, this video is an incredibly in-depth testing process, with great knowledge of every test used even in cylinder pressure testing while blocking the intake. I haven’t ever seen that before, excellent work Gary 👏👏🙏🙏
Proper logical diagnosis rather than guessing. We have a real competency shortage in the motor industry and your videos provide skills transfer to those interested in your content. Stirling work. Thank you.
Some injection specialists are happy to supply new injectors on piece without even checking yours, I was informed that the continental injectors used in the ford Connect can’t be checked or repaired, I was told it’s throwaway part. Great content .
Quality diagnosis Gary, I used to work in a Volvo truck dealership and often had vehicles towed from other dealers like this one, it’s incredibly satisfying to eventually nail the root causes but often made more difficult by the parts thrown at a problem beforehand
Very detailed diagnosis. If you’re not testing your simply guessing.I know that in the USA some ford petrol engines have issues with premature cam roller bearings are failing.
Fantastic video Gary. Thoroughly enjoyed it. The higher hourly rate for your professional excellence in diagnostics is less than the much higher cost throwing the parts cannon at the vehicle and high cost of labour hours spent trying to diagnose the fault, not to mention losses of reduced vehicle turnover and unhappy customers . Look forward to your next video
Belt timing is an issue on these aswell. Have see them jump time due to a worn tensioner (circumference gets smaller due to worn plastic belt goes slack and jumps
Proper diagnostics! Up with the best of them in my view, great explanation too for us wannabe mechanics. Very nice kit, thanks for taking the time to share your knowledge.
Another new subscriber! Fantastic video. Making me even more hungry for auto diagnostic. I love it! I work on these psa engines all time. Build em back up after timing belts snap. Can wait to see the outcome. I came across a damaged crank pickup disc but it threw a code up for it. Those camshaft lobes I've only seen move upon piston valve contact. I've just learned how much you can see from a simple amp clamp on starter. Thanks for educating and I'll be sure to keep on watching!
Excellent video mate and very nicely explained, just shows what skills and tooling you actually need to diagnose faults. Too many techs now just rely on what a code reader is telling them what is or could be faulty - needless replacement of parts at great expense to the customer chasing faults.....diagnosis by substitution!. After all that testing I'd be very suspicious of the engine timing too especially if the belt has been off to change the fuel pump, timing a tooth out? 🤔
Mate i have a transit 2015 1.5 diesel wont start . Low fuel pressure. Injector passed leak off . Fuel filter is replaced and primed . And iv removed the pressure regulator off the pump and seems to be working fine .. and a new rail pressure sensor have you ever came across anything odd on them . Theres no metal filings in system from bad pump bit odd any help be great
That is amazing what you have done! I live watching your movies and see knowledge and professional attitude. Looking forward for another investigation.
Oh man this is amazing, this is exactly what am looking for, i was just scrolling up and i found this wow video...y've got a new subscriber here and am tuned for the rest of this and the next video..thank you so much.
Brilliant video as always. I always learn from you diagnostic processes and they are logical. The cost of your skill is always justified if explained in this manner. It's also leaving the customer in charge of the process. Love seeing the Pico in action. If i was still active in the workshop, i'd love this kit and to learn. I've sent your channel to many people i still know in the trade Please keep taking the time to record these videos. (the sound was also much better in this video, new mic?)👍
I have a 2019 transit courier with the 1.5 tdci engine, service regularly at main stealers never run correctly from day 1, no fault ever found, done over 100000 mile, had a fault with engine that was diagnosed with turbo failure, replaced by independent and informed me that cam timing was slightly out
Unreal. All makes perfect sense as a lay on looker......meanwhile in my 4bdc fault bmw 520d.......I've no joy. I've got all the diagnosis from "it could be this or it could be that". Anyway, I'm learning alot about wiring and realise how little alot of shops know.
Great video Gary. Wonder if the cam lobes have somehow managed to spin 🧐 strange one but I’m sure you’ll get to the bottom of it if they let you proceed
These engines have an issue with the pressed-on cam lobes which are known to slightly drift over time as a symptom of wear. That could explain the difference in timing between the individual cylinders.
It does sound like the cam lobes have shifted on the camshaft as you have proven everything else to be okay,that only leaves mechanical failure,I believe the aftermarket camshafts are solid and not with press fit lobes
Nice video, I watch pine Hollow diagnostics he’s a guy in USA he goes into all this really deep stuff all the time when the mere mortal mechanics fail seen loads of problems like this on his channel when they have phases time and or chain / belt that stretch et cetera so it probably is the timing I would think , keep up the great work love the videos
Thanks for the input. There’s no history of cam belt failure, the owner has had van from new. Also if it had suffered cam belt failure causing the lines to spin I’m pretty sure it would not be affecting all cylinders.
I seem to be having a similar problem, no trouble starting, but when driving, getting to around 1500-2000 revs and it's spluttering and cutting out. I had the cambelt changed around three weeks ago. Could this be a result of that? It's booked into Ford in the morning to hopefully diagnose and repair 👎 great just before Christmas 😆 Unfortunate circumstances brought me to your fantastic and well indepth video Keep up the good work 👏
this happens because of a slightly open egr! it was interesting to see the amount of air measured by the maf, if it is low it causes a low diesel injection not enough to start the engine until the cylinders increase in temperature!
The EGR is fine, if in fact the EGR was sticking open there would be Driveability issues, excess turbo lag. As mentioned in the video, the van once running drives fine.
@@intelligentauto737 Yes, I agree, I mentioned this situation because I've seen these engines not starting because of the slightly open egr. Anyway it is an amazing diagnosis only the air intake part is missing!
Thanks for taking your time Gary. U made it clear,from in cylinder wave form I was a little concerned abt the time when the valves open though we had no known good. Thanks I love it,stay blessed
Another great video Gary. Keep posting more often. I hope you get the green light for continuing this, after all it is you who seems to have got to the bottom of it, all previous work was basically parts cannon big time.
If 1.5 tdci timing belt snaps the lobes on the camshaft are only pressed onto a hollow tube and can move and send the timing out it happens regularly so check the camshaft lobes to see if they have spun but normally only happens when belt snaps
I truly say what an interesting diagnostics you have done going too deep into it as no dealership would ever do that and off course i would not expect you to be the cheapest place as time is money and investing all those tools have to you back one way or the other . In that case it would have been much cheaper for your diagnostic time rather than replacing all those components for nothing. well done keep it i like your work. By the way what was that diag tool name you used it to do can-system checks , was it Think Tool or what ?? Thanks
thank you very much for the information, I have a question here. According to the fisrt graph you did, the injector pulse should be just before the peak value of the current (befor TDC), am I right with this?. the injector pulse you Got was at the TDC.
Great interesting video, cheers. Would it be an issue with oil pressure to the lifters as you said all the valves seems to be opening late and closing early? Just a thought? Can't wait for a follow-up on this.
Fantastic video!People like this calm man should tech yong people who wants to become a good mehanic.Keep them coming i know that filming takes too much time but stay on track!...Cheers!
I'd suspect the glow-plug system initially, just because. I'd be measuring the actual amps being drawn by the control module as the engine cranks, on the glow-plug control module feed wire using a clamp meter. If it is any lower than 50 amps then there is a plug issue even if there supposedly isn't a plug issue. Clamp meter onto the + feed of the plug module - see is it drawing close to 50 amps - if it isn't, the plugs are kaput or the plug feeds are bad. Because the parts cannon was fired up, I'd be doing some serious staring at the plug control module, the plugs, the wiring to the plugs & all the grounds related to the plug system.. I may be dead wrong, but that's my guess before seeing what the actual fix is - it'd be boring otheriwise. God loves a guesser. :-) Plus that's a PSA motor & they don't like getting out of bed unless a fire is lit under their backsides first thing in the morning.. from experience. No plugs glowing - no startey, no matter how hard you curse. Just my 2c. :-) Once started, they then re-start fine all day - PLUGS. I'm prolly dead wrong.. :-)
Having grown up watching Colombo and Quincy m:e. This is top grade c s i . Talk about leaving us in suspenders. My monies on worn cam lobes. Please tell Gary...😝😝😝😝😝😝
I have a fiesta with this engine. How long does the filter/exhaust cleaning last? Would have the possibility of an accident vehicle (no front damage) to get the filter for a third of the new price as an original component.
At what point can you rule out a stuck open/ closed egr valve in this scenario as you said the engine does run OK but sounds a little flat to your ears. Thanks again for taking the time to make this video.
Just found your channel. Great video, will definitely be watching all your other ones. Has it had a cam belt change due to snapping? The rockers break on these, then spin the cam lobes. Definitely something to ask the customer
Timing belt idel pulleys get worn on 60 000 km and 40 000 miles are about the same so timing off sounds the problem i have seen those engens too 90 000km and valves are bent belt broken and so on
is it possible the cam lobes twisted on this engine had it had cam belt replace in the past due to breaking AS NOW VERY COMMON FAULT but its very low milage is it genuine ,also heard tow starting cars can cause this problem if starter motor had gone as due to slack in belt then attempt tow start can cause excessive strain on belt in wrong position thus put strain on cam but not crank myth or not ,,as manufacture specify do not tow start modern cars for this exact reason ,this could be the fact that cars now have dual mass flywheel allow a rocking motion unlike a constant pressure using a starter motor this in turn allows the belt to loosen tighten loosen causing timming issues allowing valves to hit pistons ,as said a myth or not ,but manufactor believe this is an issue
I am no expert on cylinder waveforms, but did you closed the intake completely? This would cause there is coming in less and less air because your compression is also lowering in the waveform so I would think that can cause the differences, between your comparrings, would it not be possible to leave a little bit off air entering the cylinder just restrict it.
The whole point of fully restricting the intake is to create definition in the wave form, as the engine turns the compressions will deplete as there’s less air available

Proper logical diagnosis rather than guessing. We have a real competency shortage in the motor industry and your videos provide skills transfer to those interested in your content. Stirling work. Thank you.
because there is no more logical or critical thinking skills anymore. that is why math and physics is important subjects.

Exellent, thorough diagnosis. It's unikely but I have seen shifted press-fit cam lobes without any prior piston to valve contact.

Interesting diag.👍 I've seen the pressed on cam lobes spin in the shaft in DV style engines.
My moneys on that the lobes have slipped, seen that a few times.

No it’s never had a belt failure. It has had the belt off as the HP pump was replaced
@@intelligentauto737 Ah right. Definitely worth checking the sprockets and lifters then. Hope you find the fault, and upload a part 2
Was the hydraulic "lifters" the fault???
What about a in cylinder pressure waveform coralated to a camshaft sensor tdc to compare tdc variation? To rule out woodruff/ timing belt wear?
i know the camshafts get damaged when the timing belt breaks ,i have not seen the 2rd video yet

Hi, my van is literally doing exactly the same and no one can diagnose it. Was there a final solution to fix this?
