Vf calais v 6.0 litre lifter replacement issues

[vf calais]

It all sounds confusing as it's a warranty claim yet you have to pay something ($1500) out of pocket while the mechanic couldn't fix a simple lifter issue on an AFM V8. I'd still focus on sorting out the warranty side and why AFM now doesn't work (something any capable mechanic should be able to explain)...

Guess it all comes down to what you really wanted as the repair decision should have occured and been costed before work was started.

If you wanted to retain AFM to keep the car standard so you don't have to tell an insurnace company it's modified, then you definately need to sort out the above warranty repair of AFM lifters. If you actually wanted to delete AFM, once you decided to act on the lifter tick and chase some extra power, that's a different issue which you would have first researched and decised before your car was in bits... I'd not want a mechanics incompetance with AFM issues to cost me more $$ on a warranty repair that should not cost me nothing to begin with

As to installing a LS3 cam in L76 V8, not sure what that even means as a CAM is speced on value timing, lobe sepatation and lift and other stuff i don't know about. And i don't think LS3 only came with one CAM spec (it's used in lots of applications) so who knows what he is actually planning to use and whether i'd be ideal on your L76? There just isn't enough info to state anything other than he can't sort AFM issues so of him in doing a CAM upgrade on my car.

Seems like the mechanic me be pushing you around and telling you some stories for his own benefit and i guess i just don't like doing business in that way

Thanks for the info...will look into this and call up holden on there recommendation on what's right...

Isn't the LS3 cam the main reason for the >30kW increase in power over the L77?

The L77 is 6.0L V8 with active AFM and E85 capability puching out 260kw (though manual version had AFM deactivated and punched out an extra 10kw).

Meanwhile LS3 is a 6.2L V8 lacking AFM & flexfuel but produces 304kw in Holdens (and 317kw/325kw/340kw in various HSV;s)
I suspect that there are things other than just CC and CAM that are different between the L77 & LS3 I've read injectors are different but i'm sure there are more differences

The cats been in the shop now 2mnths diagnosed as lifters due to ticking sound when starting, mechanics replaced lifters and everything associated with it, valley plate and what not...upon starting the car after everything was put back together and cold starting, informed me that the car was only using 4 cylinders when running, now hes getting some dude from Holden to hook up a laptop to the car and said that it may just need reprogramming to get the other 4 cylinders to engage...im confused...

These people that worked on your car sound like idiots ! And this is WHY I as a mechanic won’t work in Automotive workshops they rush through their work to get quick money , fail to research most jobs they do from start to finish they make mistakes you take it back and they still have no clues to fix it ! I’m a very experienced specialist but I won’t work for a bunch of plebs in Workshops who claim they are mechanics but really are not

Give me your thoughts then mate...

I suspect you've had backyarders work on your car. For starters, the cam and lifters should be replaced as a set according to the workshop manual.

I would also suspect that if they've done a random "lets throw some lifters in it" then they've perhaps not used the right lifters. The lifters on 2/4/6/8 are different to 1/3/5/7 as one set is collapsible and the other set is not.

@Smashfist, the workshop manual states 1,4,6 & 7 are the AFM cylinders and thus need the collapsible lifters...

@vf calais issue was that his repaired engine started with only 4 cylinders so there was something seriously wrong either with the AFM solenoids or AFM wiring... I suspect the mechanics screwed up the VLOM when installing it or crushed some AFM related wiring causing shorts to ground (thus activating the solenoids where oil pressure then collapses the lifters).

Even though it sounds like a business did the work (since warranty was involved) they still behaved like back yarders so I agree on that point

 

[vf calais]

The car was only put in because the mechanic said it was lifters making the ticking noise, since replacing the lifters upon start up he said that only 1,4,6 and 7 cylinders weren't working...
