what you have is an example of good maintenance and repair being conducted on a vehicle that is already in good condition.

IF your intercooler hoses aren't delaminating or sucking closed then changing them wont make any difference to the performance of the vehicle. Changing them does ward off their eventual failure for quite some time as well as allowing you to conduct other maintenance such as cleaning the pipes and intercooler.

IF your lash adjustment is correctly set then checking it and making a poompteenth adjustment on one or 2 is not going to make a difference but when you come to check them next time it provides you with a better reference for how things are wearing out and when you need to check the lash caps for replacement.

IF youve gone to the effort of inspecting and retensioning the timing belt cool, now you know its condition and know that the pump is playing correctly.

IF youve been doing all your own maintenance or have bought the vehicle from someone that claims they have done all their own work and maintained it well any maintenance adjustment that you check but dont have to adjust is merely an indication of a well looked after item that will continue to offer you good service.

When you make a check then need to do an adjustment and you get a gain as large as 10% in performance then that calls into doubt the quality of the work that was done prior, is a warning of an impeding component failure or is an indicator of a component failure that has been rectified by its replacement, servicing or adjustment.

Personally it makes me happy when I do a major service on a vehicle and the customer is unable to detect any change in performance.

Just to clarify, we (Tank and I) replaced the belt, along with the pulley and the tensioner.

Before I bought the vehicle (from a Toyota dealer) at 111,000 km, it wasn't clear whether the belt had been replaced, in spite of the fact that there was documentary evidence of regular servicing and good maintenance. So I insisted on the belt being replaced as a condition of purchase. I asked that they give me the old belt in the hope that it would tell me if it had done 111,000km or 31,000km. Comparing it with the one I took out after another 80,000 km suggests that the original may have been replaced on schedule at 80,000km.

After some of the horror stories about belts, I had expected more signs of deterioration after 80.000 km. Perhaps the fact that the belt still looked in excellent condition means that my theory about the advantages of buying the last year of a model run rather than the first has some validity. By then I hoped LR had solved some of the problems of alignment and tension. It is probably another indication that the vehicle was maintained properly.

Allan, I know what you done wrong, you should have bought "Blue" silicon hoses, much faster, LOL. Anyway serious now. BTW I believe we both have the same test hill, the big bugger at the end of the Coila Lake straight (coming from your end).
When I purchased my 94 TDi 300 Disco it had 388,000klms up and it ran like a dog so I ran it up the test hill and noted the result, I knew it had problems, the rubber intercooler hoses would swell up like party balloons. Replaced with "Blue" silicon hoses and cleaned intercooler, speed over the top (held like yours) improved from 80klm/h to just under 90klm/h(110klm/h at the bottom of hill), all my speeds are from the gps.
Every time I made a change, I tested again, changing the air inlet from the Safari (snorkle) position on the side of the canister to the front got me another 5klm/h, removing the muffler and new air filter gets me over the top at 100klm/h. Not really noticable in normal driving, but noticable off the mark and pulls much better at low revs, so not a big HP increase but noticable Torque increase, Regards Frank.
P.S. have you heard from the kayaker, any trips planned?

BTW I believe we both have the same test hill, the big bugger at the end of the Coila Lake straight (coming from your end).That is the one. I'm convinced that the way the speed stays constant near the top of the hill makes it a useful measure.

Just truncate your quote of my quote to read

still apples...

as a side thought...


did you inspect the lash caps?

Go on, you know you want one. HiCloneTestimonials

Land-Rover Discovery 200TDI: When the second unit was fitted, the vehicle was transformed – it runs very well even uphill when cold.

Land-Rover Discovery 300TDI: After using the Hiclone for two weeks on the Discovery, I found it does reduce the turbo lag, enough to convince me to purchase another one.

Land-Rover Discovery 300TDI: I must say I had my doubts before but I actually got about 15% better fuel consumption on the freeway.

I had checked them about a month before I did the belt and they still looked almost brand new.

I was prompted to check them by the thread about someone's lash caps disintegrating with monotonous regularity and was pleasantly surprised to see how good mine looked.
