This is my first post on this forum, which I have come to learn is an excellent source of friendly wisdom and advice. For 7 weeks I've been the delighted owner of a 2004 UK model Bentley Continental GT. It's a fantastic car - to be honest, probably rather more than my driving skills are up to - but it has one minor problem and I hope someone can help.

The boot smelt musty, so I investigated and found a fairly good-sized pool of water under the spare tyre. I dried it all out and did the "jug of water along the top of the spoiler" test and could see it running out across the bumper on both sides. However, if I wash the car or it rains heavily, when I open the boot lid a pretty good waterfall comes down into the boot, so I think that must be the source. This happens even with the area around the spoiler and boot lid, on the outside of the car, completely dried off. If I open the boot lid slowly and carefully, the water will fall onto the area just rear of the spoiler and run away harmlessly. Is this expected behaviour or does it suggest that the drainage system is partially bunged up?

Any advice or guidance gratefully received!

Best wishes to all,
Chris (near Bristol, UK).

 

Have a look at these to start and there are even more on YouTube:

 

Many thanks BruceR. I had seen the Bentley on a Budget video but not the other one. I guess I will need to take the boot lid liner off and see if there's any particular reason for water to collect somewhere up there and only drain out when the lid is raised. Thanks again!

 

I think the drain tubes from the spoiler area would be the 1st to look at.

 

I had problems on my Range Rover with blocked drains and I used WD40 to clear them out.

 

Easy job to remove the boot liner and check the drain lines. To me it sounds like one is split.

Hello @Clunkfish ,
Welcome to 6speedonline !

As to your issue, as others have said, +.

Being that you have water coming out of each drain across the bumper, I would say the each hose/tube is connected to the black plastic funnels on each side of the bootlid spoiler area, one or both my be split as mentioned, BUT, I think the issue may be the black plastic funnels themselves, as I had the same situation, but mine didn't start to leak into the boot until after I had the spoiler cable fasteners issue, which in turn broke the clips on the top of the right side funnel, my drain tubes were intact and clear, as I had removed the complete spoiler assembly and drain tubes during my rebuild to clean all the areas and drains, when the spoiler cable retainers let loose, I did the repair (2 hose clamps and a piece of rod) found here on 6Speed by @flyc2c , but also saw that the bottom of the right side funnel was sticking out further than the left, so much, that I could see the white gasket/seal not seated, and also signs on the inner side of the bootlid carpet/cardboard of water, I am not sure how with the angle of the bootlid, but it was like the water that leaked from the funnel, was trapped on top of the carpet, then when the bootlid was lifted, the water came out between the carpet and the lid, not out of the spoiler and onto the rear glass.

I used the blue sealant as shown to put the funnel back in place, I did place foil tape over the funnel to hold it in place while the sealant cured, then gently removed the tape while holding said funnel in place.

See pics.

Many thanks to all who have replied and especially to Johnny Hotspur for the very helpful pictures.
I removed the boot liner and as far as I can see, the drain hoses look in good condition. Both funnels looked iffy; the left hand one had been bodged with some kind of hard glue and on the right the white gasket was visible but also looked discontinuous. I used black Sikaflex-522 adhesive/sealant around the edges of both funnels. My attempts were slightly less tidy than Johnny's

It will take 24-48 hours for the Sikaflex to cure, at which point I can try drenching the area again and see what happens.

Sorry Bro that looks a right mess ... A finger in a latex glove would have tidied it up abit

 

I think I'll leave fingers in latex gloves to the medical professionals

 

We had a good downpour last night so I checked the boot this morning. No cascade as I raised the boot lid and the well under the spare tyre is dry. It might look messy but it worked! Thank you to all for help and advice.

 

Glad it worked. Fortunately, no one will have to look at it!

 

Hello @Clunkfish ,
Agreed, I need the true feel of the finger, wet finger for caulk, dry finger for silicone, and the Doctors gloves for other adventures... also a micro fiber does a great job of clean up for the edges, although the towel is now trash, but worth the excellent outcome.

And don't worry about how yours looks, if it seals it seals, I have been caulking and sealing for years in HVAC, finish plumbing, finish electrical, windows and doors, I had done so many shower door/wall installations that I learned to keep it neat and tidy, never use too much to start, I used to joke that I won the "Caulker of the Year Award" 10 year running.

Glad it worked out.

Johnny

 

I actually got a pre-nuptial agreement that I will not have to do any bathtub caulking. What a pain and it never looks good for me!!!
