Hi Ek,

The dealership didn't open the engine. Their analysis was that "Metal Shaving on Oil Pan" and after they see that they blamed it on the tune because I have a recent visit at 2,000 miles and they noticed the "NON-OEM Calibration" message on the 2,000 miles visit.

A third party mechanic opened the engine for me as I want to have a second opinion about it.

 

No pics yet. I'll try to get some tomorrow. Thank you.

 

It sounds like it's a personal mechanic.

The AJ133 is a pretty robust engine that's used since 2009 in it's current 5.0L capacity in basically every JLR product line. I cant remember seeing any issues about the oil pan design being faulty?

 

Hi Shaun,

Yes, its a third party Jaguar Mechanic.

 

Without insinuating that there is a design fault with the oil pan in the F-type 5.0L, but did they not modify the oil pan design when they introduced the awd F-type V8?

So why didn't the tuning company warrant the engine ? It is they who modified it so why no warranty from them ?

 

My 5 cents is as I have said before. You modify the engine, it breaks, do not expect warranty coverage. Go ahead and argue that your mods were not the cause but I am pleased to see the manufacturer refuse warranty coverage or we would all be paying more to buy the cars initially.
I had a car that I significantly modified and I used a tuner that provided a warranty with his work, Lingenfelter. Maybe my mod cost more than a shade tree mechanic would have charged, but I prefer honesty.

what conditions were you driving in when the motor went?

what actual damage was done to the motor?

 

Sorry but its unlikely to be an oil pan issue otherwise there would be loads of failures. Remember, this engine only hit 4k miles so if its a design issue , then its very serious and would probably affect every engine. The thing that bothers me is that after buying a new car, you felt the need to mess about with it to get more power? lesson is to buy what you want right from the start , the manufacturers are clear about modifications voiding warranty's

 

Sounds like your "mechanic" may be the same one that did your tune as well, right? Sounds more like he is trying to defend himself from getting sued.

You KNOWINGLY voided your warranty when you put the tune on and ... paid the price.

Hopefully, you have learned your rather expensive lesson.

 

Yup. Talk about burning your bridges........

 

Speculation after speculation..the tuner is not the same as my mechanic.

Thanks.

 

If you're nice to people they will be nice you right? Right grandpa? You're older than me so I'm showing you respect by calling you "GRANDPA". Grandpa.

 

By saying its not the oil pan, can you please tell me if you're a mechanic? Thank you.

 

Gloomy weather..I don't redline this car. But at that time I was shifting at 4000-5000rpm

 

Because DINAN did not do the software installation. To my knowledge, No one who provides software mods for any car will offer a warrenty/gaurentee, other than DINAN. Your rolling the dice with these Indy providers.

 

Sorry that you have had these problems.

When I tune or modify a cars engine I've done it knowing that I may need to buy a new engine or rebuild and as long as I can afford it I can move ahead.

I've heard some discussions at my dealer that supports an approach of trying to carefully determine the actual root cause of the breakdown and not snap so quickly to blaming the tune. And this dealer has tuned cars coming in for service at times. Anyway, good luck and possibly an expert examination and second opinion will prove useful.

Thanks Lawrence! I already have a backup plan and yes it is an expensive lesson but hey we learn from our life lessons. I appreciate you my man.

 

I can understand your sour taste for Jaguar at the moment but in all honesty I don't think they are any worse than the other makes, like Audi and BMW who also conveniently turn blind eyes to a "known problem" - check out Audi forums for "S4 V8 4.2 timing chain guides" and you'll see what I mean. I actually find Jaguar at least easier to contact and get feedback from.

It may be that you were just unlucky getting your engine "mod" before an inherent problem would have shown anyway. If something is going to wrong it's likely to be early in its life or in the senior years. Maybe an assembly compromise, could have been anything from a poorly installed oil filter (I assume you were running on the original fill) causing oil starvation. I'm not a subscriber to the notion that if manufacturers had to cover claims from mods that our cars would cost us more. I don't believe the percentage of Jaguar modders would actually move the balance sheet that much.

You say you have other plans in hand and if I were you I would be looking at getting the advice of a forensic engineer or whatever they might be called who could provide better background on the root cause of the engine failure and what bearing (no pun intended) any mods would have had. You might also want to reach out to Jaguar UK, sometimes the USA arm can get a tap on the hand from the real parent company (I had the same with Audi USA after contacting Audi Ag).

Hopefully some kind of happy ending will come...

 

I'm an automotive engineer and i'll tell you its not the oil pan. I feel like that trumps being a mechanic. I'll also tell you not to trust a mechanic who tells you to change your oil every 3k; because that is clearly false. That independent mechanic certainly did not design/test this faulty oil pan, and probably knows nothing about it.
