Just make sure that you don't go to a bad MOT tester like a friend did. The tester failed the classic BMW (7 series I think it was) for "Excessive Steering Play". Doug was extremely miffed to say the least and asked for my opinion. "How was the steering tested?" I asked. "Oh on full lock"...

My test on the Delphi pump was done OFF THE ENGINE. Although it is slightly yucky one can place ones tongue over each port in turn and operate the lever that is driven by the camshaft. When this was done it was found that the output port would blow but the input port would not suck so in my...

I think we know about the pipes mate. There is even a little arrow that shows which port is the input. No the simple fact is that there are loads and loads of defective pattern-part pumps out there which are basically worthless. For instance when the hand lever produces strong spurts of...

15 miles, eeh luxury! My new lift pump knackered itself in less than three. The pump was new and was bought on eBay. Prior to my little test drive the hand lever would produce strong spurts of fuel from the fuel filter and the engine ticked over OK. On the return journey of my little test...

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ There seems to be a bad batch of pumps out there! The Delphi pump which did not look very old, on my 300 TDi was faulty. It would blow but not suck. (I found this out after getting filthy cleaning out the sedimenter bowl) A new...

Its the timing belt or valve timing I guarantee it! The reason why I know is that back along I bought yet another Discovery in order to move a boat (I've not had much luck at all with 4x4s) The white Disco ran OK on the test drive although it seemed low on power, however on twisty country...

Those lift pumps are one of the car's many Achilles Heels. I hate them. I had a 300 TDi Discovery running badly, jerking and running as if the engine had a misfire. Google said "Sedimenter Bowl" so I did that. After removing the rotten egg yolk, water and grit it was hoped that things would...

Yes the three way valve can be cleaned out! I've been there on a very bad dog of a Discovery 300TDi (the white one) that gave me a LOT of trouble. Fortunately I had already bought hundreds of pounds-worth of spares for an even worse dog of a Discovery (the red one) that went belly-up after...

Thanks everybody I'll now try the propshafts! (I was going to pull the injectors) The Disco is rather old and had a leaking diff pan but I needed it to do some towing. The quick fix was to pump in a cartridge of EP grease followed by a quart of EP90 oil. Hopefully the grease would fill the...

A lot depends on whether the nut is severely rusted. Now I'm a Senior Citizen who used to work in Technical Support at British Leyland and other places. There are many many methods available. (1) You could try British made genuine Mole Grips (these are made from high quality steel and other...

Hmm, I take that with a large grain of salt. For instance they WOULD NOT ENTERTAIN insuring a classic Nissan Patrol just because it had alloy wheels with 31 10.5 15 tyres. (These are not actually bolt-on-goodies from the local spot-lamp shop they are genuine Nissan parts - a Nissan Plus-Pack...

Not really but there is a possibility that either the cam timing or the pump timing is slightly out. These cars will run even when the valves are hitting the pistons. The clue is broken or badly worn valve caps. When these cars are old a top speed of 65 is fairly common but what is it that...

Please note that it should be possible to even make Britpart parts work OK. C'mon a pulley on a shaft - its not rocket science! There are numerous grades of Loctite. The common grade is for easy undoing but you can also purchase the High Temperature Retainer grade (also sold by Vapormatic in...

They look the same and measure the same diameter but possibly the number denotes the supplier OR it could be an OEM number. I do know that the spark plugs at Austin Rover Longbridge used to have an OEM number and Joe Public only got these plugs when he bought a brand new car. The idea was that...

Careful! You don't want to end up like the Nissan Navara D22s that had a bad batch of O rings for about two years. Some of these O rings shrink with age and possibly its due to the modern "Semi-Synthetic" oils that are now so popular. For example the old Petter industrial engines must...

Oh dear! I hope you've got plenty of tools as you will need them! Re the cooling system, you should check the small pipe that goes from the thermostat housing to the header tank. It joins to a plastic three-way widget that can easily get blocked-up. The one on my white 300TDi was blocked...

What was the valve stand-down? (how much they protrude from the head) The clearances on these engines is fag paper thin and its easy to get dents in pistons. F'rinstance my white 300 TDi had little aluminium tubes extruded from pistons 1 and 4. It looks as if the red hot exhaust valves had...

Here's my 10 cents worth. Its very odd that this has all happened since a cam belt change. Could it be that the valve timing is very slightly out? My white Disco 300TDi had valve dents on pistons 1 and 4. This with a 3 hole gasket (the thickest). The car has never run properly in all the...
