V8Pete

I got an HD one from Brookwell. It looks original and fitted without a problem.

It's worth checking that all the pedestals are the same heights by putting a flat edge across the tops of the bolts. If they're OK and the valves are all the same height then that leaves the rockers, pushrods or followers. The main issue seems to be the big variation between them all. Are you definitely checking them correctly in terms of camshaft angle? I used the following when I did mine recently.

When the engine is not running the silicon fluid in the viscous fan settles at the bottom at fills both chambers. So when you start it, for a short time, the fan will run as if the engine is hot as the fluid provides drive. Once centrifugal force has pushed the fluid into the correct chamber it will lose drive. To test it you need to leave the engine running for a few minutes before trying to stop the fan with a piece of card. It could be that your replacement unit was fine.

I thought a Q plate was used when they couldn't define a proper age for the car. It was a 1999 model so originally a diesel but had been fitted with a v8. The log book said it was a 3.5 but the engine number started 40D which means it's a 4.2. It had also been converted from a pick up to a station wagon. It had clearly had a lot of money spent on it looking through the receipts and it wasn't cheap parts that were used. But it sounds like the green tag could be valid if it's on a Q plate. However, the missing 60,000 miles was enough to put me off. Thanks for the answers.

I had a look at a Defender 90 over the weekend that was for sale at a local car dealer. It was a 1999 model on a Q plate. The dealer claimed it was on a Q plate because it had been exported and then re-imported, although I think that's rubbish. But what was strange is the fact that I couldn't see a chassis number on the chassis itself and there was no chassis plate on the brake servo mount. What it did have was a small green tag with 6 numbers followed by 'LR' riveted on the brake servo mount. This matched the chassis number on the V5 document. Has anyone see this before or have any idea if there's a reason for this? I decided it was all too dodgy, especially as they claimed the mileage was 73,000 but an online check of the MOT showed it was 112,000 back in 2007.

The bar style pedal came in around chassis number LA939892 so yours much have been one of the last U shaped ones. Didn't your kit come complete with a new pedal? i did the same swap on my 1988 110 and it came as a whole pedal box assembly including the new style pedal.

I believe the Santana gearbox is the standard V8 LT85 one. Assuming the crossmember is the same on the 90 as it is on the 110 then you need part number NTC1963. That's what I used on my 1988 110 which was exactly the same as the original.

I thought I was the only person sad/bored enough to do this. I previously put together a spreadsheet based on the service schedule in the pre-1993 workshop manual. I don't do the whole service in one go so I write the mileage in the box to ensure it's all recorded properly. I've added the whole schedule (petrol and diesels) and just hide the rows that aren't relevant to me. I've also added in 'Replace coolant' and 'Replace brake/clutch fluid' as these aren't listed as service items for some reason. If I get really bored then I might add an option to select the engine type so it automatically hides the service items that aren't relevant. Spreadsheet is below for anyone interested in it.

I fitted the Hawk system and it works well. Had problems initially with the central locking but traced it to a poor earth.

It looked like an ordinary deep socket but apparently it had lots of small teeth inside, rather than the 6 that the Irwin sets have.

SUCCESS! Tried a couple of garages who were unsure how to get it off. Tried an 'old fashioned' garage and he said he'd just bought some new sockets for this sort of job that he hadn't tried yet. And they work with no problem at all. Couple of taps with a hammer and perfect grip. Came straight off. And he didn't want a money for it - customer service isn't dead. If anyone's interested they were these http://www.welzhwerkzeug.com/products/product_view.php?product_id=502 Need to get myself a set. Thanks to everyone for your suggestions.

I'm just outside Chepstow - anyone nearby? Can't get the angle grinder in without damaging the hub or calliper and air sabre saw won't cut into it. Irwin bolts have now lost the sharpness on their teeth so won't bite into the bolts. Looks like heat and welding are the only options now.

I tried levering the calliper up and down and it moved a bit but hasn't loosened the bolt yet. I'll try a few more times. I don't have a welder so would need to take it to a garage to get a bolt/nut welded to it. Current plan is to cut a groove across it with an angle grinder and then use an impact driver and with an impact flat head screwdriver bit.

Sounds like I might have to take it to a garage and see if they can weld a nut on it. I'll given the Irwin sockets one more go and hammer them on but so far it just seems to have damaged the teeth on them (are the calliper bolts high tensile steel?). Thanks for the replies everyone.

Yes, I bought the extension set as well to get a 13mm as the 1/2" wouldn't fit. I even squeezed them on with a clamp while undoing them but they still didn't grip.
