dann2707 Posted September 30, 2013 Report Share Posted September 30, 2013 I'm in final year now so i'm deciding on a final year project. I've gone for, or around this area "Research into the effects of MPG and power when boost pipes cease to retain pressure on a turbo diesel engine" What do people think? I could also look at different materials and how they retain pressure better than others, along with different joining methods of the boost clips like the shitty ones on mine that use alloy nipples that wear away and lose presh!

Dave Borat Posted September 30, 2013 Report Share Posted September 30, 2013 Hi there, guys. What do you think about this cutie: GS 430 2002, costs 11500 EUR good condition, 145000 km/90098 miles. Who knows something about this cars, possible problems, how expensive they are in service? Quote Link to comment Share on other sites More sharing options...

Duncy H Posted September 30, 2013 Report Share Posted September 30, 2013 What's people's opinions on this? I really quickly painted my spare wheel with hammerite and it came out quite good. Think black steelies will look better all round? Quote Link to comment Share on other sites More sharing options...
N.Wood Posted September 30, 2013 Report Share Posted September 30, 2013 I woulda painted them silver personally, but the finish looks great on that black one. Quote Link to comment Share on other sites More sharing options...

Azarathal Posted October 1, 2013 Report Share Posted October 1, 2013 Does anyone have any idea about my steering and choking situation? Have had a read and think the choke can be solved with some contact cleaner (and welding the hole in the exhaust ) but still stuck on the steering and as I found yesterday it's getting dangerous or is it something too varied to diagnose without having a look?

RobinJI Posted October 1, 2013 Report Share Posted October 1, 2013 We can't really say without seeing it unfortunately. Dan, yeah, I'd agree with Nick, it's probably not the best bet for a dissertation. That said, you can do pretty much anything if you go into it deep enough, just beware that anything where you're analyzing an effect on performance/efficiency is going to be expensive/difficult to do any real-world testing in a scientifically accurate manner, it also limits how good job you can do when time inevitably runs short. You could probably drag out something to do with hose coupling methods into a decent paper, in which you could discuss the effects of inadequate/failed methods. MOT next week for the Leon. Shouldn't really need anything other than a wishbone bush that's on it's way out with any joy. To remedy this, I have a set of polybushed LCR cast wishbones with LCR hubs en route. Need to get my hands on some LCR front coilovers for the arb mount though which is a pain as mine are only 6 months old. Wish you could just buy fronts instead of a whole set - hoping to track some down second hand for now. It could be worth trying a Jackson Tuning on Club-Polo (The guys called Phil Jackson, he's on other forums and stuff too). He imports and sells loads of coilovers, and seems pretty flexible with people just wanting pairs or replacement parts. How complex is the mount on the strut? Is it something that could be welded to your current coilovers fairly easily? The dampers in yours should be removable, so you can weld to them easily enough, and it should be easier than trying to weld to the arms. 1 Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted October 1, 2013 Report Share Posted October 1, 2013 I've managed to pick up a pair of front LCR struts and droplinks for next to nothing which I'm going to pop on for the MOT (will raise the rear end to match obviously) so will have a proper look then.The mount itself isn't anything complex at all, effectively little more than a nut welded on there perpendicular to the strut itself. Will take a look at the possibility of getting something added if the damper is removable but I'm not sure whether they were or not (budget setup so potentially produced with no intention of being replaceable). I've also looked into a collar that could sit around the strut and act as a removable mount, so if welding isn't an option I'll look more seriously into getting a pair of those knocked up.Think that other than new ball joints (for fitting cast wishbones and LCR hubs) that should be pretty much everything done handling-wise for a while as well as obviously being MOT-ready. A little time to let the bank balance recover and I may even start thinking about power, but given that I'll be away for the best part of 9 months without access to the car I may hold fire on that for now...

RobinJI Posted October 1, 2013 Report Share Posted October 1, 2013 I'd be amazed if the damper isn't removable, every set of 'ebay' coilovers I've seen so far have been, even my Scirocco ones are, despite the fact the standard struts wouldn't have had removable inserts. Usually there's a screw in cap in the top of the lower leg of the strut, with 2 holes in it, it's not that obvious as it sits flush with the top, and they some with a boot covering all that up, but a well chosen big pair of cir-clip pliers or just a hammer and a punch will unscrew it. (I'm sure there's a proper tool for it, but I can't remember what it is right now.) Or like you say, a clap on thing would work just fine. Glad you've got something sorted for the MOT. Watch the back-end with the difference in spring rates though! 1 Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted October 1, 2013 Report Share Posted October 1, 2013 Indeed - short-term fix at best! Just means I have more than a week to source another set of front coils if required 1 Quote Link to comment Share on other sites More sharing options...
Azarathal Posted October 1, 2013 Report Share Posted October 1, 2013 Might be scrappy job if repairs cost too much, in an attempt to self diagnose the steering issue I started fault finding, started with the power steering belt, looked under the car to find a new problem - oil sump covered in oil, only checked the oil level for now (spot on) but it choked so bad yesterday I almost crashed, smoked a bit Sunday and since Sunday I've noticed the temp gauge doesn't quite hit half anymore.

TROYston Posted October 2, 2013 Report Share Posted October 2, 2013 So this happened: Diff is being welded up on Thursday. M50 manifold On Saturday. Oh the seatbelts are now gone from the rear, picture still has them in. Quote Link to comment Share on other sites More sharing options...

dann2707 Posted October 2, 2013 Report Share Posted October 2, 2013 (edited) Is anyone good at diagnosing problems?! I have a suspected boost leak when accelerating as I can hear the turbo whistling more than normal and what sounds like a big gush of air. Got some heatshrink wrap on the way to secure all the boost hoses as it's a tried and tested pikey method for my engine. I just went out and logged some data although i'm not sure if I did it right, accelerated in 3rd gear up to around 4k. Engine is a PD130 diesel. I don't really know what i'm looking for, although I think isn't the actual vs specified supposed to be on the same kind of wavelength? I had to let off throttle at one point due to speedbump Edited October 2, 2013 by dann2707 Quote Link to comment Share on other sites More sharing options...

Enlighten me please, haven't heard of this one Was going to get it De-limited so it revs up to 8500rmp costs £80 so I'll have to ask them to sort the flat spot!
