3.6 TDV8 inlet manifold repair

There seems to have been a large number of manifold cracks recently reported on the forum (maybe it just seems that way to me as mine has just gone) so perhaps the early 3.6 motors are reaching an age/mileage where this is going to be an issue for more and more of us?
I don't normally believe in "bodging" a job but looking at the price of a new manifold and the work involved to replace it this is going to be either an expensive bill or long DIY job. I figured that as mine has cracked in the same place as the bulk of those reported, on the drivers side on the top in the middle it was worth chancing £25 and an hour to try and fix it, after all worst case is I'll have to change it if it doesn't work. I don't expect this to last forever but it might last until something else terminal happens to the car.
There's loads of info on the forum about symptoms and diagnosis but I can't find much follow up on the details /results of the repair, ie what did you use, how long did it last/was it worth the effort? Perhaps it lasts for ages (wishful thinking) maybe it only lasted long enough to part ex it (surely not) or perhaps it didn't work at all.
I've been in contact with one member who did a repair with Sikaflex Marine, this lasted for 12 months which sounds very reasonable to me, I planned to use this on mine however a delivery cock-up prevented this.
Anyone care to post details of how your repair went? This could be useful to help someone considering this.
Details of mine - 2007 TDV8 144K miles, I cleaned and degreased the affected area repeatedly until there were no more black marks on the alcohol and cotton wool I was using. Roughed up the area with Scotchbrite then cleaned it again.
I used JB Weld original and allowed it to set for an hour, then put some fine fibreglass mesh (plasterboard joint tape) and another layer of JB Weld on top then allowed it to cure for 24Hrs.
It's early days but 5 days and 400 miles it still isn't leaking or showing any faults.
Anybody else care to comment on their repair?

I used JB Weld first. Lasted about a week then heat expansion made the repair come away.

Then I tried RTV. Lasted 10 miles and came away. Heat loosened it.

Then I really thoroughly cleaned the whole area again and plastered it in Sikaflex in several layers letting dry for 24hrs between and it lasted 1000 miles without trouble. I suspect it will last long term as it showed no signs of coming away, and has just enough flex to cope with expansion.

Part to replace properly is £400 alone, plus you ought to replace injector pipes and leak off seals if removing them, which adds to the cost. And it's a mission to remove all that.

The manifolds all seem to crack in the same place. Clearly a design/manufacturing issue. __

So it looks like sikaflex does a long term job - I'm pleased I've now got some if/when the JB weld fails.
I am expecting to replace the manifold at some point and I would normally plan on replacing both manifolds when I had it stripped down however as far as I can see there never seem to be any issues with the passenger side.
Has anyone had a passenger side manifold fail or are they all on the drivers side?
Thanks

The 4.4 manifolds and air intake have had 1 revision with Microcat showing them first installed on the first L405. However with all the minor engine improvements in early 2012-built vehicles I suspect that the revised parts may have been introduced at the same time. Maybe one day I'll check mine's air intake to see if I can find anything indicating that it is the revised part.

I saw a YouTube video of Bondic UV activated sealer/repairer and I thought it might work on cracked inlet manifolds

I have not tried it myself since as far as I can tell with soapy water mine is not cracked. But this stuff looks very good. 2008MY Tonga Green Vogue SE TDV8

You may need to leave it to warm up a bit and get someone to rev the engine to see the bubbles. Current 2007 TDV8 Vogue Buckingham Blue

The split on the top left of the engine block. Remove the plastic cover and it's by the injectors on the left side.

To the left of the two grey plugs is the top of the inlet manifold and it normally splits at the top. Here is a pic of mine when I put the soapy water on to track down the air leak. The angle is from the driver's side of the engine bay so different angle
