Discovery 2a 2003 V8 4L (Australian) Symptoms: (1) Oscillating between only 0V and 1.13V readings in the bank 2 oxygen sensor (bank 1 normal) (2) Had collected up error codes: P1171, P1174, P0150, P0174 (3) Exhaust sprays out liquid on ignition, quite a lot, then calms down mostly (4) Exhaust...

So I think I've spotted two issues with my Discovery 2 ACE: 1. There seems to be a PAS fluid leak somewhere from the actuator. Can I fix this with new seals or does the whole unit have to go? 2. Bushing of the actuator is buggered? Is this easy to replace? Here's how it looks. What's your...

I cleaned it off and then filmed it fresh. It drips onto the front diff and oil filter, and seems to pool under an aluminum surface higher up. I've tried to show those locations in this video (my coolant is blue): Looking from the engine bay downwards, I can't see anything. It's got a new...

Give it a nice tug. Play in which direction? What's acceptable wear on the bushes? Anything else? I'm asking because I sometimes get a clunk from the back somewhere and trying to rule things out

I've got a vacuum leak from the brake booster connector on the intake manifold: (I've put another video of the leak at the end) Question: I'm debating whether to replace the whole assembly or just the red bit. Is it easy to get just the red bit out? It's cheaper to just buy this LR052965...

I'm considering this "best 4x4 mod" from another forum, it's basically a slight PCV valve relocation on the Discovery 2a What could potential downsides of it be? Unintended consequences? Essentially you're moving the PCV valve higher up, closer to the intake manifold, so oil would be...

Here's how much it moves in park and handbrake: I often hear a loud clank when abruptly giving gas or abruptly taking the foot off after accelerating/being at inclines. Probably from that play, right? Specs of note: - About a 10mm lift above factory in the front, and about 20-25mm lift in...

I’m planning on doing my head lining in the next few weeks as it’s sagging V8 Discovery 2a HSE with two sunroofs I’m gonna also add cheap AliExpress sound deadening to the roof to help with wind noise and potentially the Australian sun What else should I replace when I’ve got it off? A)...

There's this handy guide on a PCV valve mod for the Discovery II on another forum with tons of part numbers. I googled each one of them and looked for online stores that ship to Australia. They're all in the US and most don't ship to Australia. It's a $5 part, but the ones that do, it'd come...

I have my vehicle set to Australian standards in the Nanocom. So I've been playing with the Nanocom for my Discovery 2a 2003 V8 and noticed this option in the Nanocom manual: https://www.nanocom-diagnostics.com/uploads/downloads/Discovery II Valeo BCU ECU Guide.pdf I tried it and here's what...

Hub center to wheel arch with factory coils and shocks: - Front driver: 484mm - Front passenger: 493mm After installing Dobinsons springs and standard Terrafirma shocks: - Front driver: 515mm - Front passenger: 526mm The driver’s side coil is longer… why does that side sit lower? D2a V8...

I recently changed my front coils from factory to Dobinsons C51-032 and put the longer one in the driver's side, but now the passenger side sits higher, for some reason: Front driver: 515mm Front passenger: 526mm Rear driver: 482mm (new air springs) Rear passenger: 482mm (new air springs) Is...

Whenever I turn my steering wheel to the left (and only left) at parking speeds, I get a rubbing/squeal/whine noise in certain points but not all the way through. I changed the PAS fluid in the reservoir twice already, it somewhat helped after each time (never 100% gone), but then comes back...

I've measured my suspension heights and something seems wrong Bump stop to axle bracket: Front driver 96/97 mm Front passenger 100 mm Rear driver 121/122 mm Rear passenger 125 mm The RAVE manual says that the rear (with SLS/air springs) should be 61.5 mm for the bump stop clearance. Mine is...

Normally everything is a 2 inch lift, I'm working with something less here :D My car currently: - D2 V2 4.0L with SLS and ACE - Standard height, no bullbar, factory rear bumper - All factory shocks, factory front coils, and OEM rear air suspension, factory bump stops A friend gave me some...

I opened up the door to fix my window actuator: And found some rust at the bottom, is it bad? What's a cheap and easy way to treat it?

I connected my smoke machine to the throttle body and got smoke coming out of this pipe round the back of the engine. Specs: - Right hand drive (Australian) - V8 4L - 2003 Discovery 2a (facelift) Here's a photo of the engine bay:

Discovery 2 V8 4L 2003 with a DIY smoke machine connected to the throttle body: I'm seeing smoke come out of the part with the spring where the actual throttle pivots. (That rubber glove is on there tight, nothing is getting past it.) Qs: 1) Can I repair that? Needs a new o-ring or...

Update: I found out this is the charcoal canister breather hose and that it's normal? - Discovery 2a, 4L V8 from 2003 - Car had been sitting for 24h - On the driver's side of engine bay (right hand drive) I connected my DIY smoke machine to the air intake, pumped smoke into it, and in addition...

Hard to explain this feeling, but here goes: I bought a D2a V8 with stock suspension and (probably) the factory shocks with about 75k miles on them. Sometimes when I drive on very bumpy roads and apply brakes, it feels like the brakes give out. It feels like I slightly slide forward more than...
