My Concern is how long will it last. It Is what it is.
Just another nail in. I am truly shocked at the build quality.


Have a read through this.....https://www.ftypeforums.co.uk/viewtopic.php?f=27&t=5188
 
👍

As you can see from that link, the corrosion issue on those alloy parts (cylinder head, block and bell housing) is not unusual.

I’ve assumed that you’re not losing engine coolant as you haven’t said so.

Hopefully you won’t have any further water ingress related issues.

Purchased from JLR Just had 3 Fuel injectors replaced NOT under warranty. Water ingress. apparently with every bolt they touched they snapped.

Speaking of corroded and snapped bolts on the F-Type, have a look at the state of what this member found..... https://www.ftypeforums.co.uk/viewtopic.php?p=44684#p44684

Here whats I've done to stop water getting onto the heads and in the vee, Have used EPDM roofing rubber sheet bonded to the underside of the engine cover to deflect water away from the heads, also re-routed the coolant bleed hose as the water was tracking down this and finding its way onto the top edge of the rocker cover.

Nice preventative work on your modified engine top cover 👍

Similar to what I did here....https://www.ftypeforums.co.uk/viewtopic.php?p=59388#p59388

That looks the neatest solution I’ve seen.
What did you use to bond the sheet to the cover ?
Is it holding up ok ?
 
Just bog standard superglue. It's not a whole sheet going all the way under the cover, just a few small pieces around the edges.
It's holding up just fine.
 
Hi all, new to the forum and Jag ownership, sorry to resurrect the thread again but looks like it’s died and come back to life a few times anyway.

Anyway I’ve recently bought a 2015 RWD F-Type S, so precisely the model that suffers from this… it’s got the type of bonnet vent with the one line of tiny holes on rather than the open ones, though this doesn’t look like it makes much difference.

I haven’t had any issues at all (touch wood), before I bought it I had a look on the internet for common issues etc and most articles I came across were vague and just specified that if it’s been regularly serviced it should be good, will have SOME niggles as all cars do. Anyway now I’ve done some deeper digging it looks like this is a common(ish) problem…

I just wanted to know - is this really as common a problem as it sounds? (If you google F Type Injector seizures you get a lot of hits!). But I suppose nobody is posting specifically about NOT getting injector issues?!
And if so is there anything I can do to see whether mine has suffered from this - what am I looking for, is anything even visible in the engine bay or is it just a case of you find out if an injector fails and then is found to be seized?

And, is it worth covering (as RPSN has done) the gaps in the engine cover? Does this stop the water getting to the injectors? If so this seems like a reasonably easy win and I can get some high temperature foil tape and sort over the weekend.

I think I’m just a bit jumpy now I’ve read this and a few bits about splitting coolant pipes… I’ve recently come from owning a Toyota and they’re pretty much bullet proof so now I’m having nightmares about £11000 cylinder replacements :)

TIA!

Hi and welcome to the forum.

Both the shrouded and open mesh bonnet vents allow water into the engine bay as you can see from this topic.

With regards to injector failures/seizure being a common problem, many more people are likely to report this than those who haven’t had any issues (good to hear you’re in the latter group). Of those reported, RWD drive cars seem to be more affected due to the design and position of the bonnet vents which is different to the AWD as explained here....https://www.ftypeforums.co.uk/viewtopic.php?p=48933#p48933
From MY21, cars have the vents positioned further down the bonnet (towards the front of the car).

By simply looking into the engine bay, you wouldn’t see anything visible which would indicate a seized injector.

I’ve had no injector or coolant pipe issues to date. My car (MY16) has the open mesh vents and it isn’t garaged etc i.e. it’s parked outside in the elements all year round.

In answer to your question, yes, as a preventative measure it’s worth covering the cut-outs/gaps in the engine cover as explained in this thread.
 
Water ingress does not cause the injectors to fail, its just that when you come to replace them they are seized in.
I've not had any injector issues myself, the injectors have been revised 5 times over the various model years, I don't know which revision are the worst affected.

Latest revision was from 17607

I also stick to premium petrol for the extra cleaning additives they claim they add to it + lower ethanol as a preventative measure.
Also reading any car forum about a specific car you are going to hear about all the problems people are having with that car because they all come here when they have an issue, but not to report when everything is ok. But this is a good thing because he have a database here off all the known issues and the fixes!
 
Hi jonm - that’s good information, thank you.
Do you also have the part numbers relative to the revised versions?

If you're after the injector part numbers they're all on the excellent JLR Classic website here..... https://parts.jaguarlandroverclassic.com/parts/index/hierarchy/id/C72.C7219.C7219240/brand/jaguar/

The same site as where jonm took the screenshot from ;)
 
Thanks RPSN.
So taking the V6 and in numerical order, there are 5 groups of VIN numbers and the respective number of injector revisions are 4,3,2,3,2 - quite a few then!
However, there are only 2 latest injector part numbers…
C2D55169 up to K15251.
C2D55182 after that.

Not sure how the 2 different current parts relate to any model year or other technical reason.
 
Thanks both, good to know no issues with either of your cars. You’re right that nobody generally posts to say everything’s fine! I’ve got a years warranty from the garage it came from so if I get any surprises in the next 11 months I should be covered, and now I know where to try if the injectors do get stuck rather than paying through the nose for new engine parts!
Thanks for the tip RE not being able to see anything as well, I’ll not go poking about in the engine bay at the weekend - apart from with some tape to cover the edges.
My car is also not garaged, though it sounds like the previous owner kept it in a nice heated garage so hopefully that’s helped with general condition since build, but unfortunately for the new few years she’s going to be exposed to North West rain outside my house so I’ll take extra care to look out for issues.

I’ve always used Shell V-Power in both my cars (previous car needed minimum 98 octane and I have an old Toyota MR2 that can’t cope with E10) so I’ll be carrying that on with the Jag - hopefully I don’t have any injector issues so no reason to ever find out if they seize.

I’ll have a look at my VIN later this week and check vs the list of injectors as well; you’d assume/hope that each different injector was an improvement.

Yes, like many other parts on the JLR Classic website, there are several VIN number ranges with applicable part numbers. As you point out, there are two latest injector part numbers for the 3.0L V6. The part numbers are VIN specific.

For early models, the latest fuel injector part number is C2D55169

For later models, the latest fuel injector part number is C2D55182

I’ve put them into context here....

TO VIN K13519 (C2D55169)
FROM VIN K13520 - TO VIN K14020 (C2D55169)
FROM VIN K14021 - TO VIN K15251 (C2D55169)
FROM VIN K15252 - TO VIN K17606 (C2D55182)
FROM VIN K17607 - TO VIN K58712 (C2D55182)

May that long continue for us! :)

At least the 1 year warranty you have gives reassurance in case anything untoward happens.

I’m still using black 50mm Duck tape over the cut-outs/gaps on my engine cover with no issues. I’ve replaced some of it since I first applied it just over 2 years ago.

If the previous owner of your car kept it in a heated garage, that will definitely have helped with the general condition of it.

Can’t fault the Shell V-Power fuel that you’re using....it should keep the fuel injection system healthy. I vary between Tesco standard unleaded and Tesco Momentum 99 but occasionally I do fill up with Shell V-Power.

I would think the VIN for your 2015 RWD F-Type S is applicable to the latest V6 fuel injector part number C2D55182. Whether or not it’s modified to help prevent any seizure issues I don’t know, but as you say..... “you’d assume/hope that each different injector was an improvement.”
 
Excuse my ignorance, I am a mechanical dunce. If the spark plugs were changed last year, that has nothing to do with injectors? I have a 2015 V6S, looks all good under the bonnet but I'm only a recent owner and do not know if the car was previously garaged.
 
I've just cleaned this thread up.
Technical information is always welcome.
Pedantry and arguing over minutiae isn't.
Please carry on.

Beauty of this forum, and F-Type owners, is disagreement usually polite & respectful 👍 Like two barristers picking over legalese.

My RWD V6 now 8 years old. To date not experienced any injector issues 🙌 Albeit only 28k miles, garaged & only drinks Shell V-Power.

Did change open-mesh bonnet vents to the S ones. I also try not to wash too much & even then never use power washer & always keep hose pipe directly away from that area.

That is correct.....you’re not as much a ‘mechanical dunce’ as you think you are!
