I got her running again :O When I unplugged the CAS from the loom to fix the wiring that burnt through, I must have damaged the wires into the plug - it really didn't want to come undone... anyway, after alot of messing around, I repaired that this arvo and she fired straight up :) took it for another quick spin around the block and blew absolutely no smoke this time, except some black smoke at about 5000rpm in 2nd gear at full noise. It doesn't idle very smooth, but I still have the AFM just loosely connected, and god knows when it last had a set of plugs! I've give it a full service on Sunday, change all fluids & filters, plugs, test the leads etc.

Now all it really needs is some seatbelts, tyres, and a few bulbs to get into roadworthy condition, but it might be a few weeks before I have a chance to get any of that done between work and other commitments. But its really close now, and everything is working as it should again, so I'm pretty happy atm :) . Seems to go better than i remembered too, but maybe that's just because I'm used to driving the diesel patrol all the time now :D :lol:

stagefumer11, painting and prep is sort of hard to cover just in words on a forum, but here goes...

- these old Dattos are all painted in enamel. Acrylic is the best option for a home respray, which unfortunately means you have to prime the whole car before you can paint new top coats. Can't spray acrylic straight on enamel.

- start by doing any repairs needed - rust, dents, stone chips.

- wherever you are using filler, its best to do it on bare metal rather than paint.

- cracks or crazing in the existing paint, means those panels really need to go back to metal too. You can be bodgy and use spray putty to fill them, but you'll be seeing them again before too long and that'll be the end of your nice new paint job.

- use spray putty or spot putty (aka blade putty) to fill stone chips. both of these products must only be applied over paint or primer - never on bare metal or directly on filler.

- allow any filler time to properly cure before spraying a primer over them, otherwise the thinners in the primer will cause the filler to recede, leaving tell-tale outlines through the top coats. this may not happen for up to a day after you paint the primer on the filler.

- any primer can be applied to bare metal, you do not need etch primer.

- I only ever use one step primer (aka hi-fill or hi-build primer). It can be used to fill minor imperfections missed when you were doing repairs. Its useful over filler for smoothing the join between filler and the existing paint that was around the repair. It can be used straight with a putty gun, or thinned to the desired consistency for use in a conventional spray gun, and can thinned down enough to just perform as a normal primer over the rest of the enamel paint.

- concentrate on the repair sections first. do the repair, filling, and sanding, then prime, guide coat and wet rub. repeat until you are happy with all the repairs.

- filler is pourous (sp?). it absorbs water. always dry sand it, never allow water anywhere near it.

- guide coats are your friend. a light mist of black acrylic (from a aeresol can is fine) over the repair when you think its getting close to being right, then sand lightly with a good size block. You will see where the high and low areas of your repair are. More filler may be required, or if its really close, spray putty can be used for minor finishing touches to a repair. Then prime when you really think its right with the one step primer, guide coat and sand with 600 wet and dry to see. pay particular attention to the border of the repair and existing paint. One step primer is great for this problem area.

- when you are happy with all the repairs, scuff the existing enamel paint with 400 wet and dry before priming the whole car.

- if you are careful, you can sucessfully mask off windscreens and stuff, but all easily removeable parts - door handles, locks, lights, body mouldings, grill etc should be removed. Get narrow masking tape for edging stuff, and a medium width tape for masking with paper, and a big motha wide tape is very handy too. Masking edges is tedious, but it needs to be done carefully to get a good finish. use your thumb nail to make sure the edge is nice. do not leave masking tape on for more than 1 week. and if it gets wet or is out in the sun for more than a day, remove it and re-apply - trust me.

that's all I can think of for now, but I'm sure I've missed heaps of stuff.

happy sanding!

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Duncan's V37.......race car?

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.

      My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
