I've got ACE and SLS (airbags) in my D2a V8 4L and I've noticed two things when stopping at traffic lights: 1) Sometimes the rear will lower a little. It looks like the front is raising but obviously that can't be since it's got coils, right? Or can ACE do this? Is that normal? Does yours do...

Thanks! Oh wow, that's interesting to know. Yeah good point that it didn't make it to the oil filler. Rocker cover gaskets and the valley gasket replaced by the mechanic, but I had the rough idle before that work. I hope it’s this and not deeper (like a gasket). I will try! Some plastic in my...

Thanks! This is all really great advice. I ran a DIY smoke machine through it and found some vacuum leaks coming deep from somewhere. I made a new thread for that with videos...

I have rough idle in a 4L V8 Discovery 2 I bought a few months ago and I've changed a lot of parts (see post here with symptoms and list of all work done). I made a DIY smoke machine and have smoke coming out from somewhere deep in the engine. But I can't see where exactly: Questions: 1...

Thanks for the reply! Yeah, I wouldn't know the difference. Driver turning into a mechanic due to D2 purchase here :D I took another video from the back, maybe helps? Short answer: yes, probably positive. Long answer: no negative symbol before it, but when the short term trims go negative...

Super interesting, thanks so much for your help! Here's a video of the wobble at idle from a semi-warm start: Not the worst it's been but gives an idea. Normally wobbles a lot more at traffic lights that the whole body moves. Here's a video from the exhaust: In progress: - I bought a...

Yep, it's a V8 4L D2a Side question: do the TD5s have oxygen sensors?

I had a rocker cover gasket leak, which was rectified and the bottom of the engine cleaned, but now I'm seeing this. Right above the driver's side oxygen sensor something is leaking:

Thanks everyone! Here are some replies/next steps: My mechanic said he looked visually but doesn't have a smoke machine. I tried making a homemade smoke machine with a cigar and a siphon, but it didn't work :D Yes, tried a few tankfuls of premium 98 and still the same issue. (Running E10 94...

Thanks, Sydney!

Thanks mate! D2a V8! Pretty straight too apart from a rough idle issue I'm trying to fix (made another thread) You?

I hope that someone can help me! Been at this for a few weeks with no luck. My D2a V8 has a rough idling issue which I can't seem to fix. It also throws up a lot of O2 diagnostic trouble codes. Car has around 120,000 km on it. It wobbles at traffic lights and when stopped, but runs smooth when...
