Merry ChristMASERATI! (Part 2 - Parts Required?)

The owner of the 2016 MASERATI GHIBLI Twin Turbo provided me with the OEM Service Manual, and wants the car FIXED no matter what the cost.
Let's dig a bit deeper and see why the camshaft TIMING is off on Bank 1, and if any parts will be required to perform the proper repair.

If you can turn the chain on the sprocket without removing the tensioner it needs parts!

[@throttlebottle5906]

yeah, a whole engine or rebuild.......

[@reneneron2971]

Nice work and confirmation. Something is definitely wrong if chain is going slack, even with no oil pressure. The hydraulic tensioner may have an internal spring or check valve internally that failed. Loss of oil pressure and/or contaminated oil may have created issue. Collapsed oil filter illustrates how bad things had gotten. An expensive mistake. Running contaminated oil (or not changing oil regularly) is a recipe for disaster on modern engines.

[@fsaneil]

Agree... I was thinking that too.... but gigantic BUT..... Bank 2 tentioner works. so, most likely just the tentioner failed on the Bank1 side

Yeah, that engine is pretty dark for only 60k miles... I think "10k miles" was more like 15 to 20 on multiple occasions. I'm betting on a broken spring in that tensioner that appears to be the non ratcheting type. It probably slapped around for too long and broke it.

Ford uses tensioner similar to this. The older ones would blow the gasket out allowing the oil to leak by. This would not allow the tensioner to work.

[@jessicav2031]

Pretty lucky it jumped again immediately rather than a few miles down the road! Why not compare to the "known good"? If it is that loose just because it has no oil pressure, wouldn't you expect the chain to jump during crank before full pressure is built?

[@randy1ization]

thats my thoughts as well.. there is something else that failed . likely a spring that provides a constant tension . the oil pressure is likely an assist to keep more tension on the chain during higher rpms..

[@mikechiodetti4482]

2 things. 1. What is the oil pressure at cold startup and hot idle. 2. What is the oil pressure at 2000 RPM engine at normal operating temperature. Based on what numbers 1 and 2, I'd be telling the customer what's good and not good, plus let him know about the varnish coating in the engine from a lack of oil changes. Those gear teeth on the VVT actuators look worn down. The chain is stretched, and that tensioner either has a broken internal spring or a broken internal ratchet. That engine's way to noisy. I apologize for the negative review of this engine but I can hear the frustration in your voice and I sure don't want you to "own" this vehicle everytime there's a problem especially with the engine.

I suspect that tensioner has an internal oil check valve of some sort and its now buggered. Maybe the old oil issue has effected a screen that delivers the flow of oil to it to some degree. Whatever has happened the oil in the tensioner has to hold that chain under tension at all times and its simply not working anymore.

[@scr454]

You need to replace the cam phasers ability control valves which are the bolts to the phasers. Those are the same phaser that are on 3.6 pentastar engines and p0017 is a common failure with star case to replace mentioned parts. The failure is phaser lock pin sticking. Most commonly due to the condition of the oil as seen that gold color is a visual sign of moisture buildup in oil that normally vaprizes on long heat soak drive times such as highway driving. The moisture cause the oil to break down causing the plaque like buildup causing timing component operations to stick.

[@callumcurtis15]

I'm unsure how this would cause the chain to jump ?

[@scr454]

@Callum Curtis he drove the car in. It wasn't until he tried to turn the engine from the cams(which you should never do) that the chain slipped. No oil pressure to the tensioner will cause the amount of slack. As to how the cam phaser operates to compound the slack that he found is something you would have to watch an animated video to understand.

@@scr454 It looked like the exhaust phaser jumped one tooth as he manually turned over the engine... The tensioner would not have had oil pressure with the engine not running when he moved the chain... Looks like that tensioner relies on oil pressure and it relaxes when the engine pressure drops to zero... Loss of oil pressure from a plugged oil filter before the oil bypass valve opened might allow the timing chain to jump during that time... Clean oil and a proper (new) oil filter is mandatory on newer designed engines... The car should have been parked until a proper filter and new oil was installed... I agree with what you said...

@@scr454 how does the tensioner keep tension at start up with no oil pressure ?

May sound stupid, but did they put the correct grade of oil in it? I have had issues with hydraulic lifters in the past when the wrong grade of oil was fitted, so just wondering how the wrong oil could potentially effect how a tensioner would work if it was adjusted by oil pressure alone. But somehow I think it's going to be something more than that, there must be some mechanical issue causing so much slack in that chain, if it were oil pressure alone creating the tension then surely there would always be a chance of the chain jumping when starting up. Going to be interesting to see what you find.

I know you were looking for a mechanical tension, I think that tensioner in there has just a spring for when you're just starting the car, once started it's hydraulic. At least that's how it was in my 2006 Ford Exploder, which exploded its timing because buying used I didn't know this major flaw of those engines and bought blind.

[@HouseCallAutoRepair]

Nissan had a similar design, and an aftermarket solution was a limiting cap on the adjuster piston.

[@golfmaniac]

Right away it looks like the chain may have stretched more than the tensioner can make up, or the tensioner is leaking, and can't apply enough force. My guess is the chain, due to lack of oil.

[@chrishopkins3079]

You might want to hook up some kind of pressure tank with oil in it and put 25psi oil into the pressure sensor port. (I use a cheap A/C flush can with an air regulator on it) See if that chain tensioner is getting any oil at all. I would be concerned that some junk or filter media got pushed into a passage and flow is restricted to the right side chain. It would be a lot of work to find out that the bad tensioner is just a symptom, not the cause. Keep up the good fight!

With a loose timing chain on the exhaust vale, always remove the timing chain tensioner for that bank and examine for internal destruction, clogged oil ports, etc. Chain tension on a DOHC engine is critical, obviously.

My last post on part one I asked what I will learn on part two. Very important lesson. Never buy a Maserati. Let's see what I will learn on part three. Thanks again and please keep them coming.

You mean a Masa-chrysler? Looks like you're just paying an "Italian" premium for the usual chysler junk

Great detective work. It seems their reputation as being an unreliable brand is exemplified here. Sadly now owned by a Franco/Italian/US corp, Stellantis, I'm unconvinced things will change much in the near future

Ivan this is going to be a challenge for sure. Don't you miss the good old days in the middle 1960's and the Chevy small blocks??? Pete

Good Morning Ivan,great series,just a thought,do you think the tensioners would interchange? Giving the more stressed chain a ratcheting/locking tensioner it really needs. Have a great Christmas!!
