what about the boot handle, mine leaked did everything under the sun to fix it,
the boot handle always felt a bit flimsy so took the trim off ,nicked it up the bolts seems to have stopped..
Just a thought cos we all know water settles at its lowest point ..

When I silicone sealed the entire boot seal and adjusted the compression on the seal with the boot closed, that did the trick for me. With heavy rain the water flow from the roof overwhelms the boot seal unless it's perfect. I ended up having to seal a brand new boot seal, so if yours is old, check no cracks/splits anywhere and the holes are on the inside. Heavy rain would overwhelm a dodgy seam so I'd definitely try Trikey's tip. I have a bottle of Captain Tolley's ready for the next leak, but nothing so far on the V8 lol. I do unfortunately have a small leak in the rear of the tourer with damp carpet on both sides and ending up in the wheel well. That's be my next project when I find time. Good luck. Watching this thread with great interest.
It's definitely not the boot seal on ours, although I've already sealed this as did find a small bit of water was seeping through past the underside of the seal when testing for leaks. This car has had a few boot leaks over the years and they'd always been easy to find. This is the first time I cant find the leak at all.

I then got my waxoyle out, and used a brush to force it down into the said join by the boot hinge. Never had anymore trouble with water getting in. Just try it. Costs next to nothing and five minutes of your valuable time.
I've already sealed all along there from the rear screen to the tail light. isn't coming from there unfortunately.

No definitely not coming from the boot handle. Had a check of the 4 studs from the plinth and they're completely dry.

So applied a bit more sealant in the bottom left corner of the rear screen where the black trim all the along the bottom of the windscreen finishes under the chrome trim, and applied a bit more over the joint in the metal at the top left between the bottom of the rear screen and the boot seal and that seems to have stopped the leak coming through the joint in the metal on the underside in the boot as that now appears to be staying dry (would be wet before when I'd touch the black sealant over that joint).

So this leak hopefully has now stopped


However there is still a lot of water leaking into the boot in the same spot and have found water to be leaking from here:





Water is leaking through higher up somewhere and is running down the metal and then dripping down from here. As the gap up there is pretty small I can't get my hand up there or see up there to follow where the water is coming from.

Where could the leak be that would run the water to here?

The whole left side of the boot where the seam joins the boot to the rear quarter has been thoroughly sealed from the tail light to the rear screen. The bottom windscreen clips have been sealed with overkill. The side windscreen clips look like rivets? and had a check of those whilst I had the chrome trim off and doesn't look like there's any chance water could be leaking through them.

we only had drizzly light rain last night and still this much water in the boot again this morning.

I'm also pulling my hair out (what little is left!) but I think just sealing that joint from the inside might stop the water getting onto you boot liner but it's forming a nice incubation site for rust to cook away between the spot welded lap joints; try and find/seal the outside of the same joint otherwise nasty issues down the line.

Read most of this thread but may have missed something. Just seen assistance springs on the boot struts, are these maybe holding the lid off the seal?

Give that man a gold star, the auto boot lift mod causes the exact type of leaks you are experiencing Rick.


I had this on the ZT, removed the spring set up, refitted the standard gas struts and the problem disappeared overnight.

Best of luck

Surely it can't be the boot springs if its not leaking from the boot seal? Its leaking from a different area as shown in the pics above. The water seems to be running down from the bottom left of the windscreen area and then dripping from the point highlighted in my last reply.

Hi Rick, my saloon (no sunroof) is dripping from same place but on the offside. I have tried all the suggestions on this forum but it is still dripping. I have removed the trim from the rear window and thoroughly cleaned under the edge of the glass. When it is dry I am going to completely fill the gap all round the rear window with sealer. I will let you know if it fixes the leak.

Hi Rick. I still think that your problem is the joint I referred to before. The one between the rear wing, where the hinge for the boot lid is bolted to the side. Try this. Pull the side panel away from the side concerned. Put you hand up underneath the side of the wing inside the boot. You will feel a bracket. Feel on the top of that to see if it is wet. If it is dry, put some kitchen towel on the top of it, and then spray WD40 into the joint between the wing and where the hinge mechanism is. Spray all along that joint, and if you give it a couple of minutes, you may find that the towelling is wet. You have found your leak. That’s how I found mine. I used a half inch brush and forced a lot of Waxoyle down into the joint. No more leaks now. This was on the KV6. Best of luck.

Rick, I had very similar symptoms which appeared to be the same seam. The cure consisted of:

1:Rotating the bump stops on the boot lid inwards half a turn;
2: Removing the seal around the boot opening, cleaning out all the old sealant and smearing silicone sealant around the lip before replacing the seal; pushing it down really hard over the lip and tapping with a rubber mallet to force it down onto the metal
3: Smearing more sealant under the edge of the seal and wiping off the excess

No. 1 stopped most of the leak and No.2 seems to be a complete cure following last week's heavy rain but will know for sure when this week's snow melts as I have deliberately let it pile up on the bootlid as a test.

I expect you have done all or most of this already...
