- With the timing cover removed on the 2016 MASERATI GHIBLI Twin Turbo, let's get to the fun part: replacing some worn TIMING components: chains, guides, and tensioners!
It's an intricate process, but the results should be well worth the effort :)

You need to lock your cams and have the variators loose if you have any hope of correct timing. That will have been a severe struggle installing chains without the cam sprockets floating. Your last install is with the tension side variator in your hand with the chain around it. You have a counterhold hex on the cam to loosen the variator bolt and lock the cams together with two bolts in a piece of flat bar across the cams as they will not be in a neutral position. Most tensioners on Euros do not have a ratchet, full tension is applied hydraulically using oil pressure, the spring in the tensioner is only there to maintain position until oil pressure rises after starting. We had poorly manufactured chains on some italian vehicles back in 2015/2016 which set correlation codes at start up. Most were replaced whilst still under warranty as this occurred with low mileage, however chain wear is generally a result of infrequent oil changes and/or poor quality engine oil. The oil pick up will be full of plastic so it's sump off.
By the looks of it, I'd suspect chain guide failures to be the culprit. The chain stretch length was irrelevant when compared to the slack resulting from shortened guides with loose pivots. No tensioner could account for this. The owner may want to plan for preemptive replacement of just plastic pieces in 50k miles. Now, the question is whether neglecting oil changes contributed to that failure or was this just poor quality parts (definitely a metal reinforcement/backing would help but why would manufacturer use quality parts in such expensive vehicle, the rich owner should be able to afford repairs;).
The problem may be similar to what plagued prior gen vw engines (though they also added poorly designed tensioner for good measure).
@@utuber478 I compared my original chain vs the new one. there was about 1.2 slot difference between the two, so definitely will produce an issue.
@@utuber478 guides were fine. Chains were severely stretched.

You are a brave man to take on this job ! Merry Christmas
Expanding one's expertise isn't a bad idea although originally painful it may be.
Thanks Ivan, PAD has quickly become one of my favourite car repair channels. I can't wait for the footage of you driving this car with perfect timing. The owner was lucky to have you figure it all out.

Should be a good start for anyone collecting shrapnel!
I completed a similar timing chain replacement on Chrysler 200. Chain are setup the same way. The right hand varaitors also wanted to snap toward. Just as you did I put a wrench to unload the tension and removed the old chain.
I had to remove the cams on each side to install the cam chains with the new tensioners.
Just as you did. I laid out one side only and removed the cam caps in order.
I discovered the shop that my friend stopped work on. Had put the crank out of time.
I also discovered the shop had beaten the crap out of the timing sprocket. They were attempting to install the wrong timing set also. I had to reorder the correct timing set and water pump also. It was the water pump that clued me on the wrong year too.
After all the correct parts arrived.
I loosen both cam caps on each side so the valves were all closed. Set the crank per specs. Then started reinstalling the cam chains and timing chains.
The job was about 6.5 hours total. Between my work schedule and wrong parts and delivery time. About 1.5 week delay.
The car ran smooth on the first start and customer was very pleased.
Were they the same type tensioners?
Great outstanding work! Timing is everything! Between you & Eric O you both are tops in your field . It’s hard to find good techs that are honest . You & Eric would make great teachers in this line of work .Merry Christmas 🎄 😊
Merry Christmas Iven.... Hope you post Part 5 on Christmas day, as your video's are way better than all the repeats seen on UK tv.
Turbos and Temples 3 will be released by Mighty Car Mods on Christmas day, enjoy.
@@jo300hn Yes I'm going to watch that next
If each pin on one cam chain increased "play" by .002", that would mean ((27 + 27 + 6) X 2 ) x .002" = .240" additional length in a cam chain. That's why proper lubrication is vital. Happy Holidays!
Hi, thanks for the calculation lol! Season's greetings to you and your family
Nice job ivan.
It is common for timing chains to stretch on all makes and models in the uk.
But none of us would touch a maserati.
Your a brave man lol.
Nice work ivan.
You are not only a brilliant electronics master watching you wade through that maserati past sell by date timing chain issue you are obviously a pretty darn good mechanic . drive defensively and keep breathing .best wishes from Portugal
It looks like the "special lock tool" could be replaced with just a piece of flat bar with two holes drilled in it, plus a couple of bolts.
@@n9wox Nah, I like Jessica's better.
Yeah, as we can see it's pretty obvious when you have the cams aligned, the special tool just makes it fool proof, not exactly what I'd call necessary.
@@volvo09 , Probably needed when assembling and torquing the cam phasers.
@@volvo09 The lock tools are required when setting up the timing as intended amd instructed, i.e. removing the variators and torquing them down with the new chain installed and rhe cam and cranks locked. This is very common on modern engines from many different manufacturers because it takes many different tolerances out of the equation (exact chain length, sprocket diameter, length of guides, block and head height etc) and gets the timing as accurate as it can be. Just replacing the chain/guides and leaving the variators will get you somewhat close but probably not perfect.
I've noticed many people (including Ivan apparently) do not understand the purpose behind this and think it's just not needed or some conspiracy to make you buy special tools.
@@areuaware6842 There is always areason albeit vague most times.
Last time I did a job like this, I took 30 minutes and made my own camshaft hold-down tools out of bar stock and a few bolts. It's SO much easier to get the chains lined up when you're not fighting against the valve spring pressure on the camshafts.
On motorcycle drive chains, the method to determine wear is often side flex. Lay the chain out and flex it sideways.
Hello from Australia Ivan 🙃
It's now time for us to relax and celebrate. May you and your family have a safe and happy Christmas that is full of making
happy memories.. 🍻🎄🎉 Many thanks for doing what you do..
That's awesome Ivan! So much entertainment on a lonely holiday! I spend my time with you guys!
Sending Ivan a gift? This young man has given us a year of great learning videos. Merry Christmas Ivan and wife, cat , dog, horses. ❤️
I’m amazed that the old and new chain are only a few millimeters different yet the tensioners have a huge difference! The difference must be in the wear on the guides. Merry Christmas!
You have to realize, that chain stretch is on both sides; Even though it only shows about a 1/2" stretch, if you were to cut both chains and lay them side by side at full length, the bad chain would be a full INCH longer. That's pretty crazy.. It's a LOT of stretch. So don't let it trick you; the real stretch is twice as far as what it appears, while being doubled over like that. This thing has stretched nearly two full links of chain. I'm shocked that it was still working.
Chain stretch is exaggerated when the chain is under tension and installed in the engine. Sitting limp, chain stretch is much less noticeable.
I m amazed by your knowledge and your workmanship
Merry Christmas, I do enjoy your videos your methodology of diagnostics is great.
Just saying Ivan, but these aren't the usual - they are designed to bang out some performance, so the timing isn't just "Count links" blah blah - the intake cams can require miniscule re-setting in regards to variator position once the new chains are perfectly "installed" in order to run correctly. Even after everything is on & tightened, turned by hand a few times, you might..will... need to loosen the intake variator again & reset the intake cam position - the required tolerance on intake tappet 1 is c.a 0.6mm upstroke 15' atdc (i.E pretty damn tight tolerance..) Exhaust tappet tolerances are again c.a 0.57/0.6mm with not much lee-way...again, the variator might need loosening & the cam may need a tweak.. I.E they're a complicated git to get spot on.. plus with even a small bit of variator wear, the cams won't maintain tappet clearance sequencing..so it might run, but, erm, yeah - it might not run fantastic without jumping them hoops.. But fingies crossed here. :-) Hateful engines btw...
I just love Ivan, "Before tearing anything apart".....as we look at a total tear apart. Lol. You are fearless Ivan, just total badass when it comes to intelligence and your ability to do anything you set your mind to. Even when you know, he should have walked away! I would have assumed that the two gold links should be at the same 6 O'Clock position, I would have been wrong for sure!
Thanks Dr Craig, merry Christmas!
Stay safe Ivan! And stay warm. Thanks for the videos.
Hi Ivan, suggest to the owner more frequent oil changes will make chains last longer. Many thanks very interesting repair, well done to you . Seasons greetings to you and your family from Nr Liverpool UK.
Like the GM 3.6L junk... the recommended oil changes are not enough. A vehicle should be built to withstand normal use. The vehicle only has 60K on it! I don't care if it's only had 3 changes... it should hold up better. Most owners will not change oil every 3,000 miles, which 'might' have helped this.
@@Ram14250 Hi, you are correct but we have to do what we can to try and make the best of a poor design, if people want to pose in these things.
Yup . Good advice on most vehicles actually. Oil change intervals are crazy now .
@@chrissmith7655 Sadly Chris, "most" people are not gearheads watching videos like us. They lay down a large chunk of cash and try to follow "recommended" maintenance. Only to meet disaster. Still unacceptable for such an expensive design and low mileage.
Complaints about snapped timing belts led many manufacturers to change to timing chains, which are typically engineered to at least150k mile replacement intervals. However, long OCIs and failure to maintain oil levels will have a negative effect on chain life. In addition, the stupid decision to not change the oil filter didn't help matters, as this filter could have been installed for 10-15k miles!
Ivan, great series of videos on this car, Merry Christmas to you and your family. Looking forward to seeing the final part.
Good news Ivan, Maserati is looking for techs. LOL. I bet what your decision is. AThank you for the ride
😂😂
I am so troubled by the two arrows not lining up on the bank 2 phasers as is depicted in the manual. Bank 1 they are aligned, Bank 2 should be as well. That is a big STOP NOW for me.
On our Opel, the phaser lines do not line up per OEM instructions. The Maserati instructions are not good enough so what does one do?
I was looking for this exact comment and was surprised I had to look so far down. While Ivan points this out he never explained the reason nor why it's ok to button things up with this persisting.
It was because the cams were under tension from the valve springs and the valve springs were fighting against the springs in the phasers and the timing chain. So after that cam snapped when he took the chain off, the phaser would have zeroed out to the cam and the arrows would have been aligned. It is also possible that the chains were so worn that the arrows would not line up as well. What would have troubled me more, was how he said that the jack shaft didn't have marks on it for the colored link on the timing chain- that would have drove me nuts and i would have been really cussing Fiat for their oversight.
I am so enjoying this series!
Hi Ivan,
Awesome job getting the new chains installed. Now to get the cover back on without smearing the gasket sealer. Happy Holidays to you and your entire family.
Nice job, Ivan. Very logical and scientific.
Merry Christmas.
There is no doubt in my mind that it will run great when you get done with it. Merry Christmas
YOUR MY HERO !! GREAT JOB THANKS FOR THIS EDUCATION . HERES TO YOUR CONTINUED SUCCESS. THANKS AGAIN MY HATS OFF TO YOU FOR MAKING ALL OF MY PROBLEMS SEEM LIKE CHILDS PLAY ... NEIL
The outlaws have just arrived for Christmas and I'm hiding in the study enjoying this 🤣🎄🎉
Merry Christmas, great video
So I am questioning the arrows not being aligned on the driver's side. Do you think the phasers have slipped slightly? If the cams are aligned judging from the flat surface on top the phaser arrow should be aligned correct? If that is the case does the cam to phasers use a diamond washer which could have slipped possibly.
Great work Ivan, love these videos. One thing I'd recommend is soaking the chains in engine oil before install to assure pre-start lubrication, eliminating metal to metal contact. (old motorcycle trick). The owner should reduce miles between changes as 10K miles is probably part of the issue on the chain wearout.
Go Ivan, Merry Christmas.
great job, can't wait for part 5. Vrolijk Kerstfeest en een gelukkig Nieuwjaar =(merry christmas and happy new year)
Great job, Ivan! I can't wait to see it run again. I must say that when we replaced my wife's 1997 Camry with the 2007 model with the timing chain instead of the belt, I was relieved that maintenance would decrease. She drives a lot of miles, and it seemed I was constantly replacing the timing belt, cam seal, crank seal, and oil pump seal and gasket. One time, the new cam seal lasted only a few thousand miles before it was pouring oil out - so I think replacing it that time was a mistake - the old one was better. So the 2007 Camry now has right at 200,000 miles (maybe a bit over). I think I can hear a little noise from the chain, but no fuss from the ECM about timing. The 2007 is an oil burner, though - or was until I switched to heavier than recommended oil. Compared to a Maserati, the Camry is looking pretty good, but the dash, sun visors, and the A/C evaporator were all weak points. I don't think you missed a thing on the Maserati, but with the tool bolted to the cams, any slop in the cam phasers might have been made more visible. I'm new to VVT and those long timing chains, but I've noticed that some people recommend replacing the phasers when replacing the chains and guides. Until the 2007 Camry, all I maintained were engines with timing belts and a small-block Chevy with a relatively short timing chain. Motorcycle drive chains were where I learned about worn chains climbing out of the sprocket teeth. Keep up the great work, and Merry Christmas to you and yours!
Very good install. Hope this all works out well.
Timing chains and timing belts are super rewarding to do. Pulling that grenade pin is the best feeling! You can't do a timing job without an adjustable wrench handy. lol You're doing great Ivan!
You can use 4 pairs of long nosed vice grips to lock the cams in proper position you just grab the cams in a place between lobes, and buck them up against the head somewhere.
Ivan your methodical, very well thought-out approach to tackling such a formidable repair makes it seem "almost" simple! You will be well positioned to replace the timing system at the 120K mark for this vehicle, haha! I am looking forward to final reassembly and start up vid(s). Merry Christmas.
I was hoping you'd upload this. Thanks Ivan.
Happy Holidays Ivan and crew
It's just turned Christmas Day here (10 minutes ago) and Santa has already delivered!
Love your videos brother, Happy Holidays!
Ivan, I'm holding my breath on this one. Probably a lot of other viewers are doing the same thing! Merry Christmas. Thanks for Sharing!
I would drop the sump pan on that checking the oil pick-up pipe strainer seeing the amount of missing material from the chain guides
The specialtool to hold the camshafts looks easy to construct yourself, 2 bolts and a metal bracket
Good luck, Ivan. And Merry Christmas. 🎄✨
Anyone who is fortunately to have you work on their vehicle are very very lucky not only because of your highly skilled but you do a proper methodical job well done Merry Christmas and a happy New Year to you and your family🎉😀🍻👍👍
Merry Christmas Paul!
Merry Christmas Ivan!
Great episode !
That was a surprise !
Never thought the left chain was so warn it could run loose.
Have not seen that before to such an extent on a 60kmiles/100kkm engine
IVAN, Bravo and great series full off ups and downs and how to approach this problem to fix it but with ur awesome thought process and thinking u did win to do the job well I hope the timing marks will be all good with the chains installed the way u did can not wait to see this is car is running. cheeeees
Thank you Ivan for a very nice Christmas present, part four! I didn't expect that one so soon ;-)
Me either.
Ivan certainly timed (pun intended) this one to great perfection.😀
Merry Christmas and a Happy New Year
Are usually don’t get on here to make no comments who is like your videos hope you and your family have a merry Christmas and a happy new year. Keep keep up the good work, and may God be with you.
Lookin like some light at the end of the tunnel now. I’m sure You had those timing marks figured out on the drinkers side, but I was scratching my head a bit on that but not worried. I just did a t-belt service on the 3.3 Toyota and the lower mark on the new belt was one tooth off but I knew everything was right, and it was. Nice work Ivan 👍👍
Merry Christmas Ivan to you and your family. God bless
If I had to work around that giant plastic POS air tube for hours on end I think I would lose it. Congrats on being so patient with this thing.
awesome sir, awesome. Merry Christmas.
You’ve got some guts doing that Ivan I had to put air in the tyres on my Aston once that was nerve wracking enough ! 😂❤
Merry Christmas!
Awe dawg.. you moved on out of frame
to make a part 5 now. Ya got me..
Hook, line, and sinker! Can't wait to see
The outcome.
I somehow expected more stretch, but I did not know how much stretch equates to big changes in these systems
It's not just stretch, it's also wear and tear. If you micrometer the wear surfaces there will be wear on the contact surfaces that's also cumulative.
@@groosbro1 makes sense... Just expected a more noticeable difference. But this ain't my world, just a taking a tour! 😁
Another great series. Maserati's have always been like this. If you have a Mazzer and you have to ask how much?...The first engine that used an intermediate cam-chain that I am aware of is the Jaguar XK in 1948, but it may be unusual in a V. At least your client ponied up the money in advance and they were trying to maintain their car. You could also teach plenty others how to stop yourself getting stiffed by a client. All the best for the hols.
For a job you "weren't going to be the one to do", excellent work as always! :)
My understanding (correct or not) about coloured links is they are often *not* mentioned in factory service info because they aren't actually *required* to set the timing and aren't useful to check/set the timing other than when installing new chains. It's sort of similar how most FSMs never tell you to mark the belt and sprockets or count belt teeth when you're doing a timing belt job...but almost everyone does this stuff anyway as it's more reassurance they set it right.
The coloured links are used at the factory as it makes engine assembly faster but on a service job they just tell you to go by the timing marks; theoretically you could disregard the colour links/put them anywhere so long as the timing is right. You can use the coloured links of course, if you determine where they need to be, or it's pictured/obvious, or find someone that has mentioned it along with number of links, etc. online already. In any event it *would* be much nicer if they just told you what the coloured links meant/where they go, right in the manual.
Ivan, if you want to compare a new timing chain to a used one just hold both chains horizontally in mid air and compare the droop from one to the other. The newer chain will be the straightest of the two.
A lot of the parts remind me of the 4.7 ltr V8 Chrysler engine. The last one of those I did had a tick like a bad lifter. I found broken guides and some of the bolts where nearly cut through by the chain. Also the engine was full of sludge. I had never seen such a dirty engine. The timing gears looked like a tunnel boring machine. I manually cleaned the engine the best I could and after an engine flush I had to drop the oil pan since there was an inch of sludge in the pan that blocked the oil pump intake. I would say the car needs more frequent oil changes for sure.
Merry Christmas.
Good luck and happy holidays ivan.
love those "exotic" Chrysler parts.
Getting there now Ivan .👍👍
Since you can see the pentastar on the side of each component, no doubt it's a Chrysler motor. You have wonder though if this is an engine that Maserati chose because it fit a spec, and then added turbos on top of it stressing it beyond what was expected by the original engineers.
What's not clear is how much oil starvation may have caused some of this problem, and if so, what else was damaged.
May be true anytime you put turbo's on a standard motor the motor usually doesn't last long.
I wonder if the bits that broke off clogged the oil pic up causing filter collapse and extra chain wear.... What's in the sump?? Merry Xmas to all...
Then he could have also replaced the primary chain and oil pump chain.
Merry Christmas Ivan, always great work and videos. As I write your comment and watch your video, I am using my 2300 LB saturn to jump start my 26,000 LB bus. Lol.
Merry Christmas
From what I've read, a big problem is carbon particles in the oil from direct injected engines. These particles basically abrade the timing chains and wear out the links, which is why they "stretch." One of the big OTHER contributors to this is extremely long oil change intervals on modern engines, especially when the owner doesn't check the oil between changes. So with this vehicle, we have a very extreme example of this phenomenon. Plus the filter wasn't really doing its job on top of potential lack of lube.
Good thoughts, but I think it is just natural for metal chains to just "wear". It happens on bicycles, motorcycles, and from my experience, motorized fence gates pulled by a chain. The cleaner and well-oiled you keep them the less wear and stretching will take place.
I agree. It is probably uninevitable that the chains will wear but it can hopefully be reduced with good oil. It is always easy to say bad things about stuff, and that is general way people are these days. If something breaks it is a pos no matter what it is. But in reality most engines are very good in a lot of ways. We don’t know exactly what caused the chains to wear, but most probably it has to do with too low quality oil for that application or neglected service.
Genius at work! Merry Christmas to you and your family Bill N LI NY

I wonder how common this issue actually is?
@@eugenealymov2723 Probably not too common if you keep up with your oil changes.
@@bcad4066 Only one word that is vital MAINTANCE people buy high spec vehicles & expect them to be bullet proof the opposite is usually the case.
It’s very common with timing chains, it’s the same 3.6 engine found in a dodge caravan
Thanks Ivan. Can't wait for the finale. However, I thought you would have lubricated the guides and chain a bit before installing. Maybe that is upcoming.
You're very talented. One criticism if you want to take it that way, is when I do timing chains, I always soak the chains in oil for a half hour for pre lube it so it doesn't run dry for as long as it take to get oil to the whole chain.
Great tip!
Now I know how to price a used Maserati with timing codes when I want to buy one. 🤣
Ivan, we're learning now why these expensive cars only come with a 4 year 50,000 mile warranty! Merry Christmas to you and the Mrs.
4 years is a lot for premium German cars :D Traditionally just 2 years without any extensions.
Better you than me! That car makes my head hurt!
Hi Ivan, you have got a new oil filter to fit as well I hope, and a spare to put in the boot so this doesn't happen again.
Merry Christmas and Happy New Year to you and yours.
You're the open-heart surgeon of that Maserati Ivan and Merry Christmas. If the owner can afford the car they should be able to afford the labor so 5 grand to him might be like $200.00 to others, as you know the same with BMW, MB. etc. after 3-4 years or 50-60K expensive problems set in.
Cant wait to hear it run and you taking it for it's shake down drive
Yeah designed to look good & go fast for a short time for rich people to play with & probably only lease them .
@@LesReeves Thats why so many BMW's and MB are leases and when 'average' people see them for sale they think it's only 3 years old with 45,000 miles so what could be wrong? Unfortunately they dont know their lack of reliability records.
And even worse is PLENTY of dealerships cant fix them properly, not everyone is as good as Ivan or Diagnose Dan so they can easily waste thousands on the same problem never getting fixed.
Ivan, be careful. The owner said the oil filter collapsed you see metal that has been filed away. If mettel got past that filter there is more damage then you see. there is more to the story.
Ivan, in your last vid, all the lines were where they should be after you turned the phaser. You was peeking through the phaser solenoid cover.
It concerns me that the arrows don't line up on the left bank phasers !
No way No how, That engine goes back together without answering that Question. New actuators are mandatory in my book. Ivan's lack of curiosity here concerns me. Silence on this issue is a tell.
It was weird but cams lined up perfectly and left bank wasn't setting codes to begin with so wasn't going to disturb that 👍
@@PineHollowAutoDiagnostics My thoughts that it may have jumped when you were checking chain stretch and turning the engine backwards. .
I'm still worried about the driver side phaser positions.
Cant wait for the moment when you start this piece of sheet. Im sure its gonna be a success. If for some reason it is not , I already sourced some lakes around you area. A lot of European cars manufactured in the last 5-7 years have problems with low mileage timing chains lengthening. Its just terrible.
The amount of stretch on that chain is insane. Coupled with the wear on the guides and I’m surprised the engine didn’t grenade itself unless it was a non interference engine.
You should definitely clean the oil sump and suction strainer on that car. I did the same timing chain job on a Saab 9-5 turbo and the amount of plastic and metal stuck in the strainer was crazy🙈
The cam "jumping" as you took off chain on driver side made me 'pucker' ,well ,a little bit.I would have been thinking -uh oh should held em some way.Definately will stay tuned for next episode!
since its a chrysler engine maybe an upgraded ratchet tensioner for the passengers side? in any event you're a brave man to take on this horror show of a job...merry christmas Ivan & family!
Fiat Chrysler + Mazarati = Expensive Disposable Vehicle. Continue with your experiments. I find them intriguing but I have no envy. 👍
That's a great engine the f160 your are a misinformed retard
Hey Ivan! Merry Christmas! Does it strike you as odd that the arrows on Bank 2 variators do not line up as in the service data, but the marks and plated links do, as well as the flats on the cam? Even odder, the lines and marks AND plated links on Bank 1 DO line up. Perhaps the variators on Bank 2 aren't locked at base timing for some reason or another? I have done more timing jobs than I care to admit, (and none on an exotic) but that would scare me shitless.
