StephenFord Posted September 19, 2019 Share Posted September 19, 2019 On 'spring cleaning' my boot and checking the spare, I saw a puddle of water sitting in the wheel well. After drying everything up, I noticed 2 x bungs (?) which instinctively I thought should have had some sort of drain hole to allow water to escape rather than just gather. Am I wrong?

iantt Posted September 19, 2019 Share Posted September 19, 2019 No, it shouldn't leak water in the first instance to require holes to let it out. You need to find the source of the leak. 2 Quote Link to comment Share on other sites More sharing options...

LOL, I know that, but my GT4 has drain holes, as did my old C class Merc. What are the 2 x bungs for then? 1 Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted September 19, 2019 Share Posted September 19, 2019 Drain holes in the boot!? That's pessimistic! They're just manufacturing holes filled in with grommets, you can pp the grommets out to let the water out but they're not designed to constantly drain. 1 Quote Link to comment Share on other sites More sharing options...

What are the 2 x bungs for then? Could be two prongs which support a stack of boot trays on the production line, stop them falling around aswell as allowing excess paint to drain when dipped The rubber bungs then fill these holes, I assume your boot spoiler seals around the bolts have deteriorated as there only made of foam, I recommend getting a blanket and placing it on the roof outside of the car; Open the boot then unbolt the spoiler following this guide: The spoiler then rests on the blanket not scratching the roof of the car, Clean the area and ensure its dry; Use a tube of bathroom silicone to form a ring around each bolt hole on the outter boot panel surface between the boot and the spoiler itself much like cucumber slices in a sandwich This will prevent the leak Then refit the spoiler to the boot, They end.... Vehicle will smell like a chip shop for around three days due to the acetic acid in the silicone but will be fine forever more there after. 2 Quote Link to comment Share on other sites More sharing options...

Do it yourself not difficult atall just count the number of full clock face rotations to removing each bolt; This way it wont be too tight when refitting or pull through the spoiler 🤯 Quote Link to comment Share on other sites More sharing options...

RAIDER32 Posted September 19, 2019 Share Posted September 19, 2019 I'd try the lights before tackling the spoiler, I had water getting in on my old Mk2.5 Focus from the lights, It's really easy removing the rear lamps, just a screwdriver I think, They get loads of dirt underneath creating space for water to get in, just give everything a good clean underneath and tighten back up. 2 1 Quote Link to comment Share on other sites More sharing options...

Heres a guide for removing the lights too; https://www.fordownersclub.com/forums/topic/43587-guide-fitting-ford-rs-led-rear-light-units-focus-mk25/ The one tube of silicone sealant should do the lot on the same dry day 😂 1 Quote Link to comment Share on other sites More sharing options...
Lenny Posted September 19, 2019 Share Posted September 19, 2019 @StephenFord Also the windscreen washer jets; there seals deteriorate and allow water to drip inside the bonnet from the outside in; This issue really affects the 1.6 petrol focus because the ignition plugs are positioned directly below the jets which if not sealed allows the plug tunnels to fill with water and rust, So a bit of silicone around the jets under the bonnet works well too. Really only affects the 1.6 petrol the most though. Some owners fit a Volvo engine cover straight fit to the 1.6 petrol focus 1 Quote Link to comment Share on other sites More sharing options...

Through the bolt holes in the boot spoiler because the original washers were just polystyrene seals much like stationary folder ring stickers, It then drips down the inside panel along the side of the boot and ultimately in to the well, These are all common issues 2005-2011 You need to remove spoiler to seal between it and the boot for best results, I done mine as preventative maintenance, Look up about bonnet leaking and water ingress on ignition plugs on the 1.6 petrol focus if your doubting me lol I didn't realise you had that engine though I was just saying the jet seals are another common issue Quote Link to comment Share on other sites More sharing options...

We had a similar pool of water in boot. Turned out a join in the rear washer feed pipe in where it meet the tailgate had come loose, so every it was used some water ran down the back of the roof trim and ended up in the boot. 1 Quote Link to comment Share on other sites More sharing options...

StephenFord Posted September 20, 2019 Author Share Posted September 20, 2019 Well I have just cleaned the rear lights, my goodness there was some crud in them! I feel quite hopeful now that all cleaned up and hopefully getting a proper seal, it may have done the trick! Some 'before' and 'after' shots... 2 Quote Link to comment Share on other sites More sharing options...
StephenFord Posted September 22, 2019 Author Share Posted September 22, 2019 Well, after 24 hours of a brilliant Northern Ireland summer (read constant rain 😀!), my leak is not fixed. It is definitely sourced on the RHS of the rear, and I just cannot see it being the spoiler as the tailgate is bone dry. However, as can be seen from the attached photos, the trim of the rear wing is wet. When I removed the rear light, the grommets for the 2 x locating pins looked in great condition with no obvious tears or gaps. Has anyone any more suggestions of possible source of leak? (Ignore any raindrops in photos, as they are, actual raindrops!) Quote Link to comment Share on other sites More sharing options...
RAIDER32 Posted September 22, 2019 Share Posted September 22, 2019 If it was me I'd have to check the light again, they are right above the leak, Maybe dry off around the light before taking it off, then if it's wet underneath then it must be that, Maybe use a clear silicone sealant. 1 Quote Link to comment Share on other sites More sharing options...
F0CUE Posted September 22, 2019 Share Posted September 22, 2019 Best bet would be to take the trim off and try to follow the source of the drip. Are you sure the rubber trim just above is not deteriorated? You can maybe consider this later lol 2 Quote Link to comment Share on other sites More sharing options...
StephenFord Posted September 22, 2019 Author Share Posted September 22, 2019 Was just having a look at my photos I took with the lights removed, and have a query - what is the question marked grommet for? I never paid any attention to it before... The photo is of the LHS and looks in good condition, but can't remember what the RHS one looks like. 1 Quote Link to comment Share on other sites More sharing options...
F0CUE Posted September 22, 2019 Share Posted September 22, 2019 I would say to cushion the light so it doesn't rattle/rub on the paintwork. Or they were originally going to separately wire the lights sections. Quote Link to comment Share on other sites More sharing options...
south_bound Posted September 22, 2019 Share Posted September 22, 2019 I had exactly the same issue, and on the right side as well! What I did was to clean off all the gunk and put a good dollop of grease around the screw holes as that is where I think the water was getting in, especially as it only happened on the right side which is the side I have had to replace a bulb in the past by opening up the lens. I haven't had an issue since, although to be fair it hasn't rained a whole lot through the summer. I will wait till be get a good downpour to see if it has permanently sorted out the problem. 1 Quote Link to comment Share on other sites More sharing options...

Mine was right side too, maybe a design flaw? I can't remember any difference from the left side, it was about 5 years ago. 1 Quote Link to comment Share on other sites More sharing options...
