Quick tip for all Daihatsu owners of 4X4's, too many are now suffering the terminal chassis rot, particularly those who use them extensively for their designed purpose; off roading.
When it is wet and muddy, place a hosepipe in the chassis rails and wash them out regularly, this is best achieved with one end of the vehicle raised, this washes out any mud and debris which accumulates inside the chassis rails. Do not be tempted to use a jet wash, as these are often too powerful and wash away any rustproofing still inside the chassis.
chassis rot
It's also a good idea to waxoyl every two years all the internal chassis faces and the cross pipes and rails. This will replace any lost protection and there are enough holes in the chassis to give good access with a pressure wand. I would do it when the weather gets warmer and then leave it on some paper to drip freely

Good point. It's a good idea
Good point. It's a good idea to remember that Waxoyl can also be diluted with white spirit to about 30% without reducing it's effectiveness... it also makes it much easier to use as it does not clog up the nozzle, you don't need to keep shaking it and runs freely throughout the members.
I use one of the small Hozelock pump sprayers you get from Wilkinsons for about a fiver for the external surfaces. Great for ensuring that all the nooks and crannies are covered.
Happy new year all.

CHASSIS ROT
Hi Dave
All the best for 2008
I tend to put a 5 ltr can on the Primus, lid off of course and then put it in hot at about 60lb pressure. It then creates a fine steam spray that gets everywhere. Wife keeps her distance for a few days as I stink of the stuff.:D

Steaming
Used to use rope dubbin, we would spray this into vehicle chassis with high pressure steam, usually when we were on nights at work, this stopped the most ardent of rot boxes from rotting. Whatever happened to the good old days of industry having high pressure steam fueled by coal.
Rotter
One thing I do whenever possible is to fill the chassis with industrial paint, to do this you have to get one end of the vehicle up high enough to fill the chassis. Using hydraulic hose bungs, I bung every hole in the chassis, I fill the ends with two plastic bungs as well, pour enough paint into the chassis to fill it, leave for about 10 minutes, and remove the bungs one by one; starting at the upper end. Drain the paint back into the cans, and work down the chassis, removing the bungs; this is time consuming and you require a lot of industrial paint, this etches into the steel and gives fantastic protection.
Once dried, I tend to fire old engine oil at high pressure into the chassis rails, this uses the old oil, and ensures an unlimited supply of protection, you need a large number of pots under the chassis holes to catch whatever drips out.
