Just read every page mate. Bang on, when it comes to body work and welding I'm a novice and it scares me but you've shown me there's nothing to be scared of! 

 

Matt.

Cheers Matt. It's been a trek and congratulations for reading it all! Must have taken you a while! I would say that it's not he best how to guide! But the cars in one piece still!

Little update.

Still waiting on my pistons to be sorted

House offer has been accepted! Estimated move in time. This year? Haha, I'll take some garage pics soon!

Bear with people.

Little update,

Solicitors are moving ahead on the house :)

Still waiting on pistons to come back from the garage, bank holiday weekend has put me back.

I thought I would do some painting of the engine bay and removed the remaining part of the mini engine steady bracket

Looking pretty grubby, paint is flaking in places also

Bracket removed and surface rust ground off

Nice coat of paint

May fit some foam to protect the frame when I refit the engine too.

Update again soon :)

Well then, little update.

 

Went and popped into specialist components, they do some real tasty alloys there. Hmmm.

41159878442_ebc3a89ab9_z.jpg20180402_145000 by Lawrence Balls, on Flickr

 

This doesn’t look right

39394628670_ec24a7f072_z.jpg20180402_182058 by Lawrence Balls, on Flickr

 

Im missing a clip and the one remaining doesn’t look complete. I wonder if that’s the cause of that strange noise during idle when the clutch release bearing is in freewheel.

 

Contacted Nissan the other week and they ordered one up from London for me and I picked em up today.

 

On that topic. Gearbox removed

41205101661_a8f3dc016a_z.jpg20180402_185923 by Lawrence Balls, on Flickr

 

cleaned up and a few air holes drilled

27330794698_21de55f506_z.jpg20180402_205053 by Lawrence Balls, on Flickr

 

made a reinforcer for the gearbox steady

39483222060_3ca465ccde_z.jpg20180403_175222 by Lawrence Balls, on Flickr

not finshed it yet tho.

 

Also done some grinding on the exhaust. Needs some more welding. 41292483111_0f9503612d_z.jpg20180403_180706 by Lawrence Balls, on Flickr

40396086395_ee1df26705_z.jpg20180403_191311 by Lawrence Balls, on Flickr

 

Currently im using bolts but im worried im going to cross thread the head. So ive bought some new stainless studs to go into the head and also will modify the exhaust to allow me to leave the majority of the manifold in situ should I remove the engine. (in pic below)

41292482031_8472c44b10_z.jpg20180406_113004 by Lawrence Balls, on Flickr

also bought an adaptor plate for the oil filter allowing me to fit the sensors for the digidash to the engine.

 

Sharkfin antenna arrived also. Bit big. May not fit

27420170128_ef3cf624a8_z.jpg20180406_113029 by Lawrence Balls, on Flickr

 

Have bought some new bits tho called rubnuts. Drilled out for the headlamps

40396084855_52d207b081_z.jpg20180406_115817 by Lawrence Balls, on Flickr

 

I need to paint where I have drilled tho. But they work great. Ive bought another 50 to fit the wheel arches with. Basically they are like rivnuts but rubber and brass. So no corrosion and easy to remove.

 

Then my parents car overheated

27478232868_f3a13d61d6_z.jpg20180408_195425 by Lawrence Balls, on Flickr

I diagnosed it as water pump failure due to the erratic occourance. Its being fixed under warrantly.

 

Back to mini, still stripped waiting for parts

40454398775_4e8acd53ed_z.jpg20180409_105107 by Lawrence Balls, on Flickr

 

got these to fit too

39541125610_6ccaaf5dfd_z.jpg20180409_110334 by Lawrence Balls, on Flickr

ill let you guess what it is but ill hint it involved vinyl.

 

Pistons back from the mechanics. They never bothered doing them. Could have bloody told me they didn’t have the skills to do them as opposed to wasting 2 weeks of my time and countless phone calls.

 

Chain drilled the conrod

39541071070_12bf525054_z.jpg20180409_190839 by Lawrence Balls, on Flickr

41349675201_6d1b959f49_z.jpg20180409_194315 by Lawrence Balls, on Flickr

 

all the pistons free of their rods

41306921842_2103e8ea06_z.jpg20180409_204022 by Lawrence Balls, on Flickr

 

ive dropped the other rods that I want to keep into another engine shop who are pressing them for me.

 

Interesting note. One of the above rods are bent! Far right one.

 

That’s all for now. My vinyl surprise will be unveiled soon. And hopefully the piston will be sorted soon!

 

Lawrence

So I gave her a good clean and polish today, the paint at the back is definitely the better paint!
41327999172_64baafd214_b.jpg20180410_131924 by Lawrence Balls, on Flickr

And then made a start on her new look :)
27499841158_a426a48817_b.jpgIMG-20180410-WA0002 by Lawrence Balls, on Flickr

And from the front
27499844658_a45de8f4d1_b.jpg20180410_192459 by Lawrence Balls, on Flickr

I need to do a little paintwork round the front and need to buy some more vinyl to to the offside of her. Running out!
Pistons will be dropped off soon

Hope people like the new look :)

I wouldn't fit that shark fine personally, had one on my Minus and it looked terrible, ruined the paint and has left a hole in my roof that'll be a pain to fill and paint.

Vinyl looks good, I have a similar plan for mine, but just doors, boot and bonnet and incorporating number boards.

Cheers for the comments guys always nice to get motivation! I'm unsure about the sharkfin currently. It's not essential to getting her in the road so I'll have a think

Well I've don't nothing to her in the last 2 weeks basically. I've been working a lot to try and build my money up and have also paid for just under a grand for all the house fees and a holiday this month. The house purchase is coming on nicely and I can't wait to start making my own custom garage layout!!

So plan is post payday. Order the rest of the vinyl. Order some wing paint protectors so I stop scuffing the paint on the wings now they look nice.

Pistons are finally pressed on!
41627646642_ce4f5f3d6e_b.jpg20180423_115707 by Lawrence Balls, on Flickr
Cost me £65 in the end. They are fitted lovely now tho and I didn't have to stress about them.

Orange sister mini encouraging work
41473222652_21ddd68016_b.jpg20180412_094016 by Lawrence Balls, on Flickr

And I'm just doing some mods to the lower arm mount.
40762843125_8d83bc8b37_b.jpg20180423_190152 by Lawrence Balls, on Flickr
You can see where the pot joint has smoothed the metal somewhat. I thought I may a single we'll make some more clearance now it's all apart

But as always there's an issue. The piston rings I bought were for the wrong age micra. K12 not k11. The seller had advertised them wrongly as fitting a cg10de engine. I've got my money back today (£45) but I am having trouble buying any online. Nissan do stock them but over £100im reluctant to pay that much. Watch this space the next week or so. Things will be happening!

Little bit from today.

New piston rings ordered! Found some for £73delivered! So I'll get cracking with them next Tuesday and Wednesday when the gf is at work!

Onwards to some head work
Cleaned up the exhaust gasket sealing surfaces and fitted new studs.
41675015471_e03db2733a_b.jpg20180424_154927 by Lawrence Balls, on Flickr
Like I said previously I was worried stripping threads in the head using stainless bolts like I was before.

Drilled and tapped the head for the temp sender for megasquirt
26807986927_7b04681a0d_b.jpg20180424_154930 by Lawrence Balls, on Flickr
Bit nerve wracking that! Didn't want to bugger the head up. My lucks not great haha

Then I capped the other sender holes. Was going to buy some new brass bungs but in the end I cut up the old sensors and silver soldered them up.
40785116945_8be575b46e_b.jpg20180424_170428 by Lawrence Balls, on Flickr

39868852100_c1a247214f_b.jpg20180424_170634 by Lawrence Balls, on Flickr

41635899002_3f2a025e02_b.jpg20180424_170958 by Lawrence Balls, on Flickr

Sure buying the brass bits would have been faster but it was much more fun making my own and recycling :)

And I'm working my way along the head lapping in the valves. The tool I have from Halfords is very poor quality, I think I will replace it after pay day.

Good evening people,

 

This is the first of this weeks updates. There will be plenty coming this week as I crack on!

 

Correct rings finally fitted to the pistons!

41761485582_cd67acf9b5_z.jpg20180430_102438 by Lawrence Balls, on Flickr

 

work desk cleared and block dug out

27934768968_8634823dd8_z.jpg20180430_103247 by Lawrence Balls, on Flickr

 

Crank and cage fitted. Oil filter adaptor plate fitted also.

41086221514_d82900c10c_z.jpg20180430_124218 by Lawrence Balls, on Flickr

 

I also tested the end float and its within spec. For this build im not changing any bearings etc as all of them are fine. These engines don’t tend to wear like the a series ones do and it’s a 5 bearing crank too so less flex etc.

 

And pistons all fitted. Considering ive never done this before it all went nice and smoothly.

41086227604_62e0f9e2ce_z.jpg20180430_152203 by Lawrence Balls, on Flickr

 

Crank turns nicely and I can turn it by hand so im happy ive put it together ok. Used most of a kitchen roll and a whole can of degreaser. Although the exterior of the block looks grubby all the mating faces and bearing holders etc ive cleaned the best I can.

 

Ive put it to one side for now.

 

Onwards to the sump. Need that to protect my oily bits!

 

Hammered out bit cut out to be replaced

41766111022_5bc0df8f24_z.jpg20180430_154717 by Lawrence Balls, on Flickr

 

panel made and partly welded in, my cad template is there too

27939558528_8544305e29_z.jpg20180430_155850 by Lawrence Balls, on Flickr

 

weldy weldy – the blue tray is to catch oil and snuff out any chances of remaining oil going up in flames. Fire extinguisher was nearby!

41807940131_e051f0045c_z.jpg20180430_161047 by Lawrence Balls, on Flickr

 

Painted – cut out bit next to it

41766078672_500c67eccb_z.jpg20180430_162303 by Lawrence Balls, on Flickr

 

I have also rewelded the exhaust where I ground it back

26939753707_152d68cf31_z.jpg20180430_164005 by Lawrence Balls, on Flickr

sorry for the poor photo.

 

In addition to that ive bought some carbide bits to clean up the exhaust and open it out a little so ill tidy the ports up when they arrive.

 

Ive also redesigned part of the exhaust where it enters the Y piece. Its all tacked currently (note the pigeon pooh welding)

 

Instead of the 2 clamps that seems to fail after only a few miles ive devised a new system of keeping the exhaust more air tight. One part slots inside the other

41766473462_44b1296aa5_z.jpg20180430_184454 by Lawrence Balls, on Flickr

41766468772_17cb40ba67_z.jpg20180430_184617 by Lawrence Balls, on Flickr

 

In addition to being more gas proof its also a low profile as this part of the exhaust is snug to my subframe.

 

More tomorrow.

Exhaust finished and painted using scraps of paint left in the garage!
27956171728_22d264829d_h.jpg20180501_103503 by Lawrence Balls, on Flickr

Making the most of the nice weather while it's not raining! Suspension all stripped down.

40017284170_542c9fcc7c_h.jpg20180501_114743 by Lawrence Balls, on Flickr

Cutout for more clearance and welded up to keep the strength up. I'm finally happy with this area!

Evening update
40932588965_4128ee8996_b.jpg20180501_174537 by Lawrence Balls, on Flickr

Lower arms fitted and suspension rebuilt back up. Everything is done up but not yet retorqued. I'll do that once the engine is refitted incase I need to take bits apart again.

Gearbox is now also refitted. I wanted to check my new gearbox mount and clearance where I did my welding this morning. Clearance is really good. I still have to have my driveshaft gaitor transfer thing fitted to fully avoid any chance of the gaitor being shredded but I expected that unless I was going to redesign more of my frame in that area.

More on Thursday. I've ordered a new valve lapping kit that hopefully will be better than the current one I have!

That's all for now.
Lawrence

Cheers bud, I've set them the same as my current arms so hopefully will be accurate and the adjustability will be great.

Few bits from today
Went to lap in valve with my current tool
27999736478_37fc1974d0_b.jpg20180503_103907 by Lawrence Balls, on Flickr
Waste of time, tools rubbish. So rather than waste my time I cleaned up all the bolts and chain etc and sorted all my shims out and cleaned my gasket faces. Means when I finally get my new valve lapping tool I'll be able to put the engine together fairly swiftly.
40969940625_dde36e895c_b.jpg20180503_120832 by Lawrence Balls, on Flickr

27999650508_e407d0a0f0_b.jpg20180503_171816 by Lawrence Balls, on Flickr
Also refitted the light and did other bits to tidy the front up.

That's all for now. Night shift Saturday night so I've got all day then to sort the engine should my parts finally arrive! Also bought a micrometer to allow me to shim the valve clearances appropriately

Lawrence
