  1. I suspect the £700 is all the parts required for MOT and labour,not just the subframe.
  2. It's getting very very hard to find parts for older cars through the normal channels. I think many supply chains broke during covid and the less lucrative ones have never been re-established. I this is one of the main reasons mechanics are tending to avoid working on older cars and are so keen to write them off for simple problems. Forums such as this one are a godsend as they provide information on specialist suppliers, specialist garages and even the technical knowledge for DIY.
  3. Wales is so full of little gems it's hard to go along all of them in one lifetime.
  4. Last time I sold a car (other than to friends) was 20-30 years ago and autotrader worked the best, paper version back then. For buying, I've found gumtree tends to have much more genuine sellers. Ebay is just full of con merchants both buyers and sellers. If it's in particularly good condition (sounds like it is) it may even be worth looking at Mathewsons, though it's probably too new still.
  5. I had something along similar lines on my SS1 but that also included very rough changes which gave a bit of a thump in the bavk changing up at higher revs. The gearbox eventually went bang overtaking and left me with reverse or neutral. Sorted with a gearbox change, wasn't ecu.
  6. I think classifieds were moved from being a sub-forum to their own separate place which may have caused some confusion.
  7. i would try TCB or gT4 play as first port of call.
  8. I've got a pile of centre caps at the factory. I never fit them as they can fall off. That was my old workhorse back when they were cheap - I rescued that one from scrap as it had LPG so was as cheap to run as my diesel clio on long runs.
  9. Worth trying TCB as well. www.tcbparts.co.uk They also do secondhand parts and loads that's not listed on the site.
  10. On the gen 6 you don't actually need the engine running, just ignition on and push the throttle. If you have a second person they can keep the throttle down to keep it running.
  11. In both cases the Toyota red is the best stuff to use. I've seen inside engines run with Toyota red, and engines run with normal aftermarket stuff. I also forgot to mention, blipping the throttle with ignition on also provides confirmation the pump is working. It's becoming increasingly common as the age goes up for these to stop working. It's usually worn out brushes in the motor but often worth getting a re-con pump. Available from GT4-play or TCB. Either low level or failed pump will produce the code 54 error.
  12. What they don't tell you is to do it with the pump running as this drops the level at the cap. Blip the throttle with the ignition on and the pump should run for about 30 seconds.
  13. I would tend to contact Martin Kingston as a first port of call. MK autos in Blackburn. Standard pistons plus standard rings cost nearly the same as forged which come with rings.
  14. Not looked in a gen 7. The gen 6 has quite a few SMT but still quite a bit of through hole. To a certain extent I was forced into SMT as many of the newer chips just aren't made in through hole. I'm fortunate to have a local SMT production company which does small quantities without huge charges so it's actually become cheaper than through hole even in 25's. I am starting to be able to handle SMT myself although only for prototypes, not for production as I don't have an oven to ensure the correct heating profile to solder reliably under chips whithout overheating them. These things help enourmously: https://uk.rs-online.com/web/p/magnifiers/1830966 Tantalums are fine provided you stay within the voltage ratings, they are very intolerant of voltage surges. Although they are low ESR I still tend to use them with a paralell ceramic, this may also make a difference.
  15. I've certainly heard that E10 goes stale faster. Water in small quantities isn't harmful other than causing local corrosion if it's stood - some of the GT4 guys fit water injection when running high boost to keep things cooler and reduce detonation. From my experience garden machinary isn't made to the same standard as cars unless buying top quality professional stuff. Cars have much more legislation governing things like fuel compatibility, garden machinary it's just market forces. If a £150 mower goes wrong after 3 years people just shrug their shoulders and buy another. It's very different with a £15K car.
  16. Polymer capacitors are fairly new and I don't have much experience. I tend to use Tantalum for the medium capacity / low ESR applications. For the higher capacity / higher voltage stuff where Tantalum isn't available, neither is polymer so I stick with the traditional electrolytic plus paralell ceramic or polyester. Nowadays for a 10uF / 12V decoupling application like the main caps that fail in the ECU I would just use ceramic, although Polymer may cope with over-voltage surges better.
  17. When these ecu's were designed, 10uF ceramics were unhears of. I think 0.47 was about the limit.The surface mount era has brought about minaturisation of all components. You can now get 10uF in 0402 size (1mm x 1/2mm) although not up to 16V. This has also impacted on through hole versions. ESR is part and parcel of why electrolytics don't like ripple, particularly high freqency ripple. Where the larger capacity of an electrolytic is needed, it is normal to put a ceramic capacitor in paralell to handle the high frequency / sharp edges of any ripple. This wasn't done on the capacitors I've looked at in the ECU. Electrolytics are much less common in modern designs, mainly because they don't apply well to surface mount for 2 reasons. Firstly the larger sizes would just break off the board with any vibration or shock. Secondly, surface mount soldering is done in an oven which heats the component as well as the board up to soldering temperature. Although through hole electrolytics can be used, it's very difficult to automate the through hole assembly so it;s not ecconomic for mass market.
  18. http://www.gt4dc.co.uk/forum/viewtopic.php?f=2&t=5617 A good few years on now and while it's been mostly gt4's it's also affected other models and the gen 6's as well. I suspect it's more apparent in the rarest models where spares aren't readily available so people ask fot help. My opinion is that it isn't poor quality capacitors although that is a possibility. We're also starting to get some of the other values failing now. I suspect it's probably a combination of age, temperature and use. Heat is one of the primary causes of ageing, and the ECU is mounted under the heater outlet on top of the exhaust tunnel !! The other ageing factor is high frequency / high ripple current, and the first capacitors to fail were on the power rail feeding the idle solenoid. I did switch to ceramic capacitors for replacement of the 10uF as these don't suffer the above problems and are more suited to 'decoupling' on supply rails, however someone reported having a problem with the ecu, changed back to electrolytics and it was fine.
  19. The rm380 in one go is very poor quality and virtually unreadable in places but useful to have as a single document. All my collection has come from the net, when I see something I don't have I add it so always useful to add links. I'll try to keep my external links maiintained, the problem is that so many free hosting places close down public links sooner or later. Already been through photobucket, dropbox and google drive. As I said, hopefully we can host the files within this site eventually.
  20. I've now posted all my stuff in stickies for each gen section.
  21. Looks like pcloud may do the job. I've uploaded an ST205 manual to try if someone can try downloading it. I think it pops up an advert to the service with the download. https://e1.pcloud.link/publink/show?code=XZWpVLZ2HLAABFqblHujw7SNKE7K0xPbTs7 If it's successful I'll upload all my stuff and put it in stickies in each section.
  22. Maybe we'll look at putting storage within the site as & when we move to a new server and we have more control over it. Meanwhile I'll look at one of the free file hosts mentioned and see if I can upload my stuff there.
