If it's tapping it's time to replace. That one if refitted is rapidly going to get worse & you'd be taking it all to bits again. An idea of tappet wear: http://www.v8engines.com/faq-gen.htm#worntappets

The camshaft needs replacing. Normal to replace camshaft and the followers at the same time, any damage or wear will rapidly affect new items if you don't. If the compression is fine I wouldn't worry about the bore - although if you've got it in bits then no reason (and might give you peace of...

www.optimabatteries.com/experience/blog/fact-alternators-are-not-designed-to-charge-dead-batteries Ignore the advertising of their own batteries. Your neighbour's battery needs fully charging with a battery charger & then see what happens, but likely it's knackered. 20 miles will achieve...

Weak mixture flashback? Unmetered air entering the system after the airflow meter?

Is it actually misfiring or do the revs just dip then pick up again? Check the wiring connection of the harness at the AFM. The flapper doesn't have the stepper motor idle valve of the later ones.

I think more likely 'the number of the beast'. Revelations 13 verse 18: Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six. Bit more: https://en.wikipedia.org/wiki/Revelation_13

LRcat ( https://new.lrcat.com/#!/1233/64319/64443/5280/64552 ) comes up with these part numbers: PCH118133 for the one with the airblast PCH118134 for the one without the airblast. Pics of the two: www.johncraddockltd.co.uk/pch118133-genuine-top-hose-radiator.html...

Removal section in my factory manual starts with a warning in bold type that the unit is pressurised, must not be dismantled and repair is by replacement of the complete unit. Issue with twin axle stuff is that they're heavy & like to sit level & unlike the smaller single axles you can't really...

Uses fluid and gas & is under high pressure. Someone did try with the Defender one in conjunction with a citroen suspension specialist but it didn't work out: https://forums.lr4x4.com/topic/77667-self-leveling-unit-repair/#comments Might be of interest...

My thoughts too. If the Boge self levelling unit has failed then the rear won't self level. Don't forget the car needs to be driven for the Boge to pump up. They're no longer available although Kingsley list remanufactured units, but at 2k +VAT you're probably better fitting Disco 1 rear...

The head bolts - or the stud washers & nuts if you've fitted a stud kit - effectively seal against the head so oil can't pass up or down them. There are oil passageways from the block up through the heads & rocker shaft pedestal into the rocker shafts which are hollow. Then out of the rocker...

I very much doubt it's the gauge & light. Check the connector plugs on the wires near the tank. May be corrosion issues in the connectors or penetration & corrosion in the wires themselves. Had that with the fuel pump live feed on my petrol '86 3.5EFi - down to a couple of strands inside the...

Perhaps he's going to claim he's a showman & tow more than one trailer at a time.

If it requires dealer level diagnostics to clear it & there are no independent Land Rover specialists in your area you may unfortunately have no choice.

Never heard of one & neither has the workshop foreman/manager of the caravan place I do bodywork for so it looks like you'll have to make one.

Difficult to be certain without pressurising the system & seeing where water escapes which is likely to prove difficult now it's in bits. That said I'd be more surprised if it isn't leaking between the hose & that part of the pipe that the hose fits over & I don't think the metal pipe is...

That pipe's not looking good.😲 Think it's No6 in this link. https://new.lrcat.com/#!/1230/73417/74385/5985/74837 ERC2126 although what your chances of getting one are I wouldn't like to guess at.

STC1856? https://simonbbc.com/search.php?search_query=stc1856&section=product

^^^^Good guide. It's the foam backing on the material that's the issue. Deteriorates over time with heat & just ends up as a crumbly mess even though the material is still fine. It all needs to be scraped off the backing board & if you're trying to refix the old covering it all needs to be...

The rubber seals at each end of the valley gasket harden over time & are a source of oil leaks esp at the rear. You may need to change to the later valley gasket clamps & seals if you use the composite gasket. I did. Clean the faces of the heads & inlet manifold. Thinners & a rag work well -...
