How long should radius arm bushes last?

I’ve just pulled the back axle out so I can do a diff swap and fix anything else I find in there that needs doing. I was a little disappointed to find both radius arm bushes were starting to tear. These were replaced a couple of years ago, so haven’t been in long and have probably done no more than ...

Re: Camshafts

Sit both camshafts side by side as they’d be orientated in the car, rotated so the timing slots are both facing up. The front lobe on the inlet cam should point to the right (carburettor) side. The front lobe on exhaust cam should point to the left (exhaust) side. If both lobes point the same way, y...

Re: Steering rack mounting

You should have the tubular spacers on the driver’s side only. The passenger side should have the bolts passing through from the front to back, with washers under the heads that contact the plate on the steering rack. Adjustment for the “level” of contact on the passenger side is provided by the nut...

Re: Plugging the two extra cooling holes in an XJ6 head.

There’s some risk of corrosion as brass an aluminium are separate on the galvanic scale. https://www.fastenal.com/content/feds/pdf/Article%20-%20Corrosion.pdf Brass and aluminium together is not ideal, even though they do already exist in together in the cooling circuit. I always find it nerve wrack...

Re: Steering column too short!

Was your car originally equipped with power steering? Power steering lower columns are shorter, to accommodate the longer rack tower. Alternatively, it could be someone has given the column a whack and sheared the nylon pins causing it to collapse.

Re: Belt position.

Are you sure the belts are the correct lengths? When I set mine up properly, I went to the motor factors and bought a selection of belts to see what fitted best, as I wasn’t sure exactly what I needed. The water pump belt should be easy to fit. Fit it to the water pump first as it’s too short to fit...

Re: Belt position.

The water pump should be driven off the crank pulley groove nearest the engine block. The belt is tensioned by the spring loaded jockey wheel just in front of the distributor. The power steering is driven from the second groove on the crank pulley. The belt doesn’t go around anything else besides th...

Re: Crank Bolt Tightening

I did mine on the drive with the car in 4th gear and the handbrake on. I chocked the rear wheels too, and had the front wheels under the sills as an extra precaution as the front was on axle stands. I was able to do the nut up to 140lbft with my torque wrench. It took a bit of effort, but it’s possi...

If you have a Lucas 11ac alternator, it’s best not to leave the ignition on without the engine running.

Re: Help 3 Intermittent cutting out on hot idle

I’ve just re-read your first post. My comment about the over advanced ignition causing difficulty starting isn’t likely to apply if the starter spins the engine easily. I would think it unlikely that all the plug wires fail simultaneously. Maybe the king lead has a problem? You could check if there’...

Mine broke a couple of years ago. The angle drive spat it’s inners out. On the 4.2 S2 at least, the angle drive is on the RHS, and there’s a blanking plug on the tunnel just behind it, along side the propshaft UJ. Someone had already been in and butchered the transmission tunnel, cutting two slots f...

Re: Help 3 Intermittent cutting out on hot idle

20degrees BTDC sounds high if the engine is otherwise standard. Over advanced timing can make for difficult starting. The mixture ignited and burns before the piston has reached the power stroke, so it pushes back against the rotation of the starter. Having said that, this isn’t really temperature d...

Wrong gearbox oil, will I have done any harm?

I decided to change the gearbox oil in my S2 yesterday. It has the standard Jag synchro gearbox. The chassis plate said 20w50, the workshop manual said EP90. I remember reading on here a reference to the manual being incorrect, so I used 20w50. Now, problem is my car has had a replacement chassis pl...

Re: another voltage question

Measure the battery voltage using a multi meter with the engine off, at idle and at a 2000rpm. This will tell you what your alternator is doing. Also, measure the voltage at the voltage stabiliser to see whether that’s working correctly.

Re: Radiator coolant

If the heater was set to cold when you drained the coolant, the tap that controls flow through the matrix would have been closed, so the heater may not drain. It only blocks one side of the circuit, so coolant could still drain from the other side, but there’s no way for air to get in to replace it,...

It seems very easy got get airlocks on the S2. Park the car On a slope facing up hill so the radiator is the highest point. Make sure the heater is set to hot too. If you didn’t drain the heater, that could account for the difference in coolant volume. A slightly sludges block or radiator will reduc...
