Thanks Geek, that's not exactly 'defusing' the situation now is it? :shock: :lol: :roll:

Did you notice if your radiator cap was replaced?

Got a phone call today, dealer wants my MY15 for 1hr.
In the words of the phone attended, "its a recall on the motor, we can provide you with a courtesy vehicle."
Didn't get too many details out of them and am wondering if they want to perform overheating related tests ?
She also said there is already a letter in the mail.

Does it have a pressure rating noted on it?

Actually though, what this higher pressure cap will do is exactly that.

The higher pressures will cause any engine which may have the porosity problem to fail much more quickly. Possibly even during the testing process. My information is that this is an intentional thing so that any engine which does have the problem can be identified and corrective action taken in the short, rather than long term.

What this means is that MMAL have taken a very positive step to get these fixed rather than have them linger around and get a reputation like the Nissan 3.0 litre grenade. I believe that MMAL should be given serious credit for doing this - it would have been easier and much cheaper to just fix the ones that failed.

The bottom line though, is that if you've received the text/email/letter you should hightail it into your dealership and let them do their tests.

Interesting. I replaced mine a while back with an aftermarket one from CPC. It's rated to 110 kpa. The OEM was also 110 - at least that's how I interpreted the 1.1 stamped on it.

At the time I was being told 90 kpa was what was needed. Still listings on ebay tonight for a 90kpa cap to suit a Triton.

If google maths is correct then the new cap is only about 2.5psi more than I am already running so I don't have that much to worry about I guess. Well I hope anyway.

My guess the higher pressure cap is to make the difference between combustion pressure and cooling pressure closer to help stop the combustion punching through the gasket.

The higher pressure raises the boiling point too

I thought Chris was on the money actually. The way the problem has been described to me - admittedly by about 5 different people so who knows if I've remembered any of it correctly - was that there might be a casting or machining problem with the blocks which makes them potentially porous where they shouldn't be. If that's right then the extra pressure may just be enough to push them over the edge into failure under testing?

Fine, test them under pressure to "push them over the edge"
But why run them near the edge as well

So test to try and boil my car for 5 hours in the dealers workshop at over 4000 rpm and then hand it back with a pass or fail yep I'm happy with that with the pressure on other components in the engine and revving the crap out of my car

Love That Car .....not much love after all the issues my challenger has had and now this

I really wish we had lemon laws like the US cause I would have my money back buy now

They're not idiots, mate. The tests have been designed to identify engines with the problem so they can fix it. Controlled running of the engine isn't going to hurt it one little bit and will be much kinder to other components than something like subjecting the cooling system high pressure testing at levels where the fault may be found but other things like the radiator or seals may be damaged.

I honestly don't get it with some of you blokes. They have a problem, they're trying to identify something you can't see, hear or touch, they've devised tests to find the affected engines and have voluntarily asked owners who may have affected vehicles to bring them in and, if faulty, they'll probably give you a new engine, free. But still you whinge and bitch. :?

Couldn't agree with you more 5th ;)

I've never had an issue in over 4years and 140k plus km's yet they still voluntarily submitted the changes whilst my vehicle was in for something completely different. It hasn't and probably won't change anything but at least my vehicle is marked down now as having the "change" done so if it does decide to (as geek has pointed out explode :roll: ) then at least I'll be covered :D

Their are no losers in this when you think about it if anything does happen, it'll be more of an unfortunate inconvenience possibly.

The fact is they are still using the same casting methods on the new engines or they would not be recalled, they know there is a problem so fix the casting problem. As for the comment controlled running of the engine isn't going to hurt it one little bit, I hope they are running fans just like they do when you have a dyno tune!
And we have right to bitch and whinge when they are still using piss poor blocks that they know could be faulty!

Perhaps you'd be kind enough to describe for us (since you clearly know better about such things) exactly what the nature of this casting problem is and what they're doing wrong?

I'd love to know more about it since all I've really heard is that there's this porosity issue and maybe something connected with tooling wearing down and being out of spec at the end of some production runs.

The ones that get delayed will likely be replaced in due course if they also fail but if they do manage to spread them out a bit with the current campaign then they will spread the pain out a bit and we shouldn't get stuck with massive backlogs as we wait for more new engines to come in.


Spot on Dave. Engines have to be shipped, not air freight.
