things have been s**t for my 5 the last fortnight. was out for a run then It suddenly felt like running on 3 cylinders. I got home (slowly :( ) and did some investigating.

one of the retaining nuts on the rocker arm came loose so valve no7 was not opening.

to make it worse. the nut went down one of the pushrod channels in the head so the only way I could remove it was to remove the head   :(


back of the 5 now looks like this...



whille head was off, did some tests and it looks like one, possibly 2 piston rings are worn.

so the 5 is off the road for the forseeable future till I can afford all the parts.

I am also considering selling my turbo to raise funds, its a turbo technics stage2 T25/2
http://www.turbotechnics.com/turbo/s117.htm

it has .48 cold side and now with a .47 rear. minimal side play, no in-out play.

will come will a k-tec T3 actuator. Anyone interested drop me a PM.

removed pistons & liners this afternoon with engine in situ....





was pretty straight forward, although I found it a bit awkward teasing the sump out between the subframe and engine mount - any tips to make it easier going back in?

just need to order up all the new parts and get the pistons to the engineers for new rings to be fitted and hone the liners  :D

Easiest way is to find something to take the weight of the engine and remove the engine mount that gets in the way. Although with some carefull manovering it is possible to refit it with the mount in place.

You will find it twice as hard to refit without smudging off the new sealant. A pig of a job which i have had the misfortune of doing more times then i would like.

cheers Ash, I will try that and get the mount removed when I get round to refitting   :D

in that last pic James?   :(                  thanks for the concern :D  :D

I had a cooland pipe split at the degassing pot some time ago and pink coolant soaked that area. The discoloured (rusty looking colour) is the paint that was affected. I had rubbed part of it with a sponge and the tungsten paint flaked off revealing the original white paint underneath.

I have been looking for a decent rattle can colour to re-do the bay in...Now seems a pretty good time to get it sorted as the engine is more or less in the boot............. :mrgreen:

been a long time since I have updated this....

about 2 weeks after I replaced the rings etc I had major engine failure.... I initially thought that I had spun a bearing or something........... but once I stripped the engine I soon realised it was MUCH worse  :(

A conrod tried to escape through the front of the block  :lol:


the completley mangled piston & liner





so since then I have bought a standard bottom end which I have completley rebuilt. as well as poly-bushing the front end and replacing whishbones, track rods and ball joints, rear disks and pads.


the new engine will be of slightly higher compression to the last one, namley due to a slightly skimmed head and ditching the low comp pistons setup and using standard comp pistons





so this is where im at now  :D   engine is good to go  8)


I just need to repaint part of the bay and the lump is ready to be dropped back in this weekend  :mrgreen:

Fingers crossed for you Graeme :D

Do you know how thick your cylinder head is?? prob with running higher comp is det / knock matey.  Might be worth investing in det scope so you can make sure you keep the car tune on the correct side of it :)

cheers James, I hope I have some luck with this one :D  

I had the head measured at 73.3mm.....so its not had a bad life and been skimmed to death :lol:

so engine will only be slightly higher comp than standard ( i think/maybe not with the h/g :?: ) ... I tried using a comp ratio calculator online but I got a little confused on what values it was asking for. So I ditched it!


 I will not be running any boost - or maybe just a little... for a while till I rack up some miles, so I will see if I can make some det cans in the mean time! although I would not have a clue what to listen for :mrgreen:

:lol:

cheers James.....I have not really driven the 5 properly yet!  I am dying to though!. I have been mad busy with work/uni assesments I have not had much time.  I have had it out my parents garage a couple of times and around their area to check everything works with no leaks...... it sounds awesome with the standard exh mani back on & sidey  :mrgreen: ! - really happy with it :D

I have changed the oil+filter twice though in this short time! and I think I am going to be really strick with it so it wont break on me! - Im sure I will lose the fear (of breaking it) once im boosting properly!

my mate is coming round tomorrow so we will be attacking some electrical gremlins and giving it a good clean!

freshly de-rusted & painted


and here it it all back in 8)
