IIRC there are a number of obstructions, such as spacers to keep the 2 c sections apart prior to welding, on a 90 the front tub mount is a tube welded through the chassis. I am sure there may be others where bolts go right through chassis with strengthening tube to stop crushing of chassis etc.

If you look at the start of this video Mike has already drills drain holes into the underside of this 110 chassis
Hope this helps |

Hi Mossberg
Apologies as I was in a bit of a hurry earlier, you know what it is like, make dinner, washing up, impending apocolypse. What I did on my 90 hardtop to get a hosepipe in to clean out the ends of the crossmember was to simply drill a hole in the rear side panels in line with the crossmember ends, painted the hole and added a grommet. When cleaning I just place the hosepipe next to it and blow the crud out. once dry I then spray oil into it. I also have rear bumperettes with corner protectors so not immediately obvious that there is a hole there. Another thing to note (I forgot at the time). If you have rear mud flaps, the bracket covers the drain holes in that part of the crossmember. I drilled a matching hole in the bracket so that I can get a hose in there as well. Hope all that make sense 
Have fun and stay safe |

Many thanks folks, I really appreciate your help.
Nice video showing the chassis wash out, though it is great doing it when the chassis is off. Does anyone know where the internal plates/braces are on the chassis? It would be good to putt access points in the chassis where a good jetwash could get in - that video just shows the importance of clearing the mud out. Thanks Mick |

I've ended up getting a drain cleaning attachment for my pressure washer. I am able to then feed it into the multiple holes already in the chassis rails.
First time I cleaned it I was very surprised how much mud and sand came out! Can't remember the exact one, but it was something similar to this: https://www.ebay.co.uk/itm/Drain-Cleaner-H...SwHv1eBH0j |

Thread revival!
When using a drain cleaner attachment inside the chassis rails.... Where does it drain from? Plenty of holes to get it in, but not sure if there are really any big enough to get muddy water and sand back out again and concerned it'll just permanently fill the chassis up with water! |

That of cause is the issue, all the holes are along the sides of the chassis and not in the underside.
Hence on the vid I attached Mike drilled holes in the underside. Interestingly because of where he is based in Canada he did an earlier video where he drilled drain holes into the underside of some rock sliders and explained that an earlier set split when the condensation froze and split the seam. In ye oldie days it was the reason that old engine oil was kept and pumped into the chassis as it would soak into any dirt and aid protection where wax oil just sits on top. It might be frowned on today but if you can protect the ground oil is still a great way to go, you can even use something like a hand pump weed sprayer to apply it, just make you own tube to enter the chassis. And yes, I’ve done it. |

I seem to remember that the use of oil like that was banned because it's carcinogenic. Darren

Thanks for the thoughts. Am wondering how on earth the chassis treaters who do the insides manage to get them clean enough to then apply wax to, without just creating dirt that's waxed over and holding water against the metal constantly.
So in terms of obstructions... if I managed to park the 110 up at enough of an angle that all the chassis angles ran downwards towards the front, would water run out of the chassis if i put the lance in at the rear and wandered it around a bit down the drain cleaner? Particularly interested if we reckon there is internal bracing around the front spring mounts.  |

^^ Whatever makes you think that they do? It probably isn't possible.

Desperate hope, blind faith and innocence!
Strikes me it's probably better not to treat the insides if you can't get them clean, at least they then remain dry whenever the weather is? Otherwise you've just waxed in a load of wet mud permanently that can't even dry when the weather is? Or am I missing something...  |

Does this hole he's using exist at the back of every chassis? I know he's drilled in the bottom of the main rails half way along... but just pondering winching the front up, making safe, and then being able to have it all run out the back.

Um at least on my chassis (300Tdi 110) there are quite a lot of drain holes along the bottom of the chassis rails at each of the low points. OK they do get plugged up fairly frequently with my use but easy enough to poke around with a screwdriver and clean out. Ed 82 Hotspur Sandringham 6x6 95 Defender 110 300Tdi |
