What did you do with your Range Rover today

[Datatek]

What's the point in the foam blocks where the wing/a pillar/scuttle meet? Do they actually do anything?

Accumulate water to aid the rusting process.

As part of the service do I replace the HT leads with Red, Bosch, Lucas or Magnacore?

Magnacore of very good.

 

[kermit_rr]

Personally.. any will be fine.. they are all silicone based with the same core

 

[kermit_rr]

Magnacore of very good.

Also very expensive

 

[Henry_b]

Also very expensive

indeed, Bosch make a good 2nd best

I think so long as you don't get some cheap Chinese knockoff , they are all of a muchness.. with an expensive label.. or not

 

[Scotiawhiskers]

Eh?

Noise, vibration, harshness.
Basically making it quieter and smoother.

Every 4 months? You must have money to burn Every 6K miles or 12 months is more than enough.

Call me paranoid but after loosing one engine like to keep on top of things

 

[Grrrrrr]

I think it's a problem with the large 4x4 tyres tbh.. so much air in them and when it's cold overnight, the heavier air molecules separate to the bottom, causing the flat spot

The heavier molecules may settle to the bottom but it won't affect the pressure or volume noticeably in the tyre as it is the number of molecules not the weight of the molecules that will mainly affect the pressure. It is the temperature drop that leaves less energetic molecules that leads to a drop in pressure and or volume. The difference in density could unbalance the tyre slightly until it is mixed up again although you'd think the effect would be marginal, especially after a couple of tyre revolutions. All this business with using nitrogen gas as air is too impure and inconsistent is unlikely to make any difference unless you're in Formula 1.

if its not heavier molecules sinking to the bottom, why else is the flat spot only ever at the bottom????????

 

[Grrrrrr]

Because the weight of the car is on top of it when the volume / pressure decreases and the ground isn't as soft as the air around the rest of the tyre.

now you're being far too sensible
the earth presses up against the heavy air molecules which are too heavy to move out of the way, thus causing a flat spot

Well air we breath is about 75 perc nitrogen so you only getting a bit more
BUT

Find a hot day - unlikely in your mud island but still

Fill one of your rear tyres with the nitrogen stuff
lower tyre pressure by about 10 perc each side
Find a highway and do 120 kph - clearly not for the welsh

find or use your tyre pressure gauge and you will be very very surprised at the new pressure difference between the two tyres - and That's what causes blowouts

Think I'm gonna treat the landy and replace the power steering fluid.. not a full flush but drain and refill the reservoir

What about your flat tyre?

 

[badfluffy]

What about your flat tyre?

just turn it round so the flat bit is at the top

 

[kermit_rr]

It can spend some time with my flat cap

I had those 32”ers on 16” rims for many many years. Never had this issue
