Well done Des, I am surprised a certain other few members managed it though!

Today's tinkerings yielded a hopefully fixed water leak. I say hopefully, it's rather wet outside and I was working on the car in said wetness, meaning it was difficult to see if the hose-thermostat joint was still leaking. I needed a new thermostat seal in the end, you can see that there are a few imperfections around the edge of the seal.

Image

I didn't even manage to burn my fingers! Quite a lot of water came out though, I reckon I must have put back in 3 or 4 liters (water and antifreeze, of course). I then waited for the stat to open and the water level dropped significantly so topped it back up, waited for the fan to come on, then go off again shortly after. Interestingly only 1 fan came on, does the secondary one only come on at a higher temp again?

It was booked in today for sphere regassing, but the bloke said it was so soft that he wouldn't bother - it wasn't worth it even if they were 5 or so bar down. After a chat with Mark on the tech weekend, I may have a look at doing it DIY.

That's all for now, next on the list will be hopefully be bumper painting - then I can get my splitter on. At a similar time, I would like to respray the trims, they are scratched and dull.

Little update, serviced the TXD today. New oil, filter and air filter. I was quite surprised how oily the air filter was, and the connecting pipework too - would this suggest a clogged breather somewhere?

The pipe photo's are of the two pipes that connect to the lid of the air filter housing. It was all quite oily in this upper part - perhaps accounting for the occasional blue smoke on startup. What are peoples thoughts?

Still liking this car, turbo lag and boost is still fun :D It also does over 50 mpg regularly with seeming no effort - I haven't even tried doing an economical tank yet, although it would be very interesting how well it could do. It will need welding fairly soon though, probably just both sill ends (but might get a whole new sill panel for each side, thoughts?) and the drivers door pillar; although the sunroof surround and a patch on the passenger rear footwell may also be structural.

From the last post, one water leak fixed, there may be another one - can't tell what is going on behind the engine, it always leaves two or three black pound coin sized patches where it sits for more than 2/3 hours, but I think it's a fluid running down the back of the engine block, then dripping off various low slung bits, like the gearbox drain plug etc - not sure if it's water or LHM either, the engine is SO oily behind here a water leak would look black (as would an LHM leak). There is usage of LHM, had to top it up for the first time since it had the front HC sorted back along, I check all it's fluids weekly as it seems to use all of them at varying rates :(

Ho Hum, it only cost me £300 to buy, so I can't complain too much, and for what it is I still think that was a bargain!

My TZD does the same. I'm pretty sure the breather system is not functioning correctly. Might also explain why it's so keen to lose its engine oil (though it's still nowhere near as bad as our Mini was!). You may find that if you can sort the breather out, oil leaks may reduce - though I'd guess that the cam cover gasket is past its best.

Check the 'wire wool' breather pieces. In the petrols it maks a significant difference about keeping the air filter clean. As Malcolm says be aware there is a 'wool filter' in the oil filler neck, and this may apply to the diesels. Agree with you on costs, mine was £300 and will need about £500 of welding to keep her on the road for at least another 10 years. It's still good value. V similar - new sills, o/s inner wing, above rear sub frame. I'm no welder but know when it needs doing. Don't want to get it to the point like Jaba discovered! Good luck.

The turbo diesels do seem to blow a bit of oil into the air filter, i had the exact same thing on mine, although it was less than your piccy, how old is the filter? I always give the air filter box a hoover as well, its amazing how much dirt is at the bottom of it, so when you put a new filter in, it gets clogged up immediately by the crap in the bottom. Some of the dirt may be ingrained, so i just use a flat blade screwdriver to dig it out before hoovering, jobbed :)

As far as the MOT is concerned, the rot in the roof wouldn't be counted as structural, unless maybe if they thought the sunroof was about to fall out.

As for the rear footwell, it depends exactly where it's gone - bear in mind that because the front seatbelt buckles are on the seats, anything within 12" of the seat mounts will be structural, which is most of the rear footwells anyway. If you're not worried about recreating the pressings in the floor, the rear footwells are pretty straight forward, although bear in mind that there's pipework under each outer edge, and the fuel tank immediately behind them under the back seat.

Thanks for the advice chaps, i'll have a go at cleaning out the breather system. Which hoses are included in this system? There's lots of 'em, and they go all over the place! I'd also like to clean out the intercooler, is this just a matter of taking it off and cleaning something? Not had any dealings with them before - not even sure how they work (apart from cooling the incoming air).

Sunroof should be ok then, quite sure it isn't going to fall off, but I expect the footwell will be structural then, it's just where the footwell starts sweeping up to give the fuel tank space.

I also would like to change the LHM soon, i'm sure it's probably not been done for some time, the front struts are really quite sticky too - would the return pipe in bottle of LHM trick improve things? I have been reading up on changing the LHM, sounds fairly simple.

The intercooler is very simple to remove & easy to clean, don't use a high pressure jet wash as it can damaged the fins, i just used a hosepipe & some engine oil cleaner stuff to clean mine up, seemed to work fine. LHM changes aren't too bad, just takes time, the only issue that you may come across is the bleed nipples being seized on the calipers. I clean them up & put some plusgas on them before i do the lhm change & then gently try to get them moving by going backwards & forwards & re-spraying some more plus gas when i've unwound them a little bit more each time.

Well somethings going on that's good, the last tank was 58.2mpg! My best before that was 53.9. Not really sure why it was so good a tank, fuel was the same (shell ultimate) and the roads and trips were the same (mostly to and from work, dual carriageways and A roads). But it was serviced before this tank, and for most of the tank (last two weeks) i've been on earlies (leave home 6am) so it's been quite cold, and I for this tank i've been sitting behind lorries at 55mph so I don't get to work too early. Pleasant surprise at fill up today :D

Got next week off, so plan on painting the bumpers and wheel trims, haven't priced up paint yet so we'll see what gets done. I'd like to clean out the intercooler too, and check all the intake hoses for leaks - it's making that noise that Mitsubishi Pajero's do, that high pitched wooshing/roaring noise - it didn't do so before I changed the air filter. like this.

Regarding the noise, does it seem down on power a bit?

A little bit, might be my granny driving recently, but there is a little more smoke - a black puff when giving it the boot.

Could there be a split in the turbo pipe so extra air is getting in?

Had a little tinker with the TXD yesterday, the weather was quite beautiful down here so I decided housy jobs can wait! I thought i'd try to investigate this poor starting some of you may have read about in the technical section. Funny thing is, it has started perfectly since last Thursday, so not sure what was going on there.

I had all of the air intake pipes off and the intercooler for cleaning. Probably should have bought a new D shaped gasket for the 'cooler but the old one wasn't too bad, i've added it to the shopping list along with other GT things (poor, GT, haven't done anything with it for ages). All the pipes had some oil and grunge inside them, some alot worse than others, oddly I was expecting the intercooler-boost compensator hose to be clogged but this was the cleanest.

Image

Doesn't this look bad? This is the intercooler-boost comp hose, after figuring out how to get the funny clip off (used mole grips in the end and pinched the sticking out bit) had to really wriggle and cajole the thing before it would move, hence the tear in the pipe. BUT, it wouldn't have torn if there wasn't an imperfection/split/hole in the first place, now would it? So I trimmed it back a bit, cleaned it and put it back on. Only thing is I couldn't get the funny clip done back up, so at the moment it's just sitting there - it's that tight a fit though that I doubt it'll come off. I'll have to go find a dinky jubilee.

Image

This is either the oil filler-round thingy (Mick! I have one on my TXD!) or round thingy-air box hose, very oily they both were. Anyone know what the round thingy is? When I blew through it and passed water through it something rotated when it passed through one way, but not the other.

Image

Round thingy, mounted on the RHS of the intercooler. Slots into a metal clip and connects the oil filler and the air box.

Image

Oilyness of the turbo air intake pipe just after the flexy section, this I didn't remove cos it looked like a right PITA to get the other end off, I didn't look, but from previous endeavors I know just how limited access in the turbo area, so didn't bother! Should really have done, but I only had an afternoon and needed to use the car this morning.

Image

Clean intercooler! Yes, I know, it's not that clean, but it's the best I could do with the materials to hand. I used the kitchen sink, fairy liquid and the hot tap. Managed to avoid getting told off too :D Steve walked in just as I was cleaning up the mess i'd made, 10 minutes previous and I think he'd have been upset!

I also had a look at looking at the boost compensator thingy on the pump. How on earth do you investigate this? Unless there is a bolt/nut or something under the end cap I couldn't see any way of taking it apart. One thing I did notice though, is that the whole module would rotate a little when I was putting the hose back on - this can't be good? I probably should have consulted HBOL, but it was at the GT garage 10 miles away, and the TXD had no intake system on it...

So still need to look at the boost compensator diaphragm, the MOT is due at the end of November, and my local BX man said it may not be worth repairing depending on the extent of welding needed - this is something I will decide though. Not him. So we're going to put it in for a MOT at the beginning of November and they'll give me a price for the work needed.

After all that cleaning, I have noticed it's a bit perkier off boost, especially at lower revs, it's smoother too. No perceived difference on boost or top end though. Looks like I will have to look at the boost compensator unit...
