Doctor, I forgot.

I've tried the (free/lite version) Torque app with a cheap reader and when it came to anything more than the very basic OBD2 stuff, I quite frankly didn't trust it at all.
I'm not saying it's automatically wrong, but it threw out stuff that wasn't consistent, imo.

lol, thats easy to answer lol, their usually it begins rattling then they get broken up badly or end up empty, plus bear in mind once ive replaced it cat problem related codes are gone, till next time.....
So thats self explanitory but its obviously an end result not a cause
Personally I belive its a combination of a lot of engine issues and I feel sure im going to end up doing much much more to eventually get this fixed properly, the stuff here that im playing witn atm is just the begining and im pretty sure the engine is incorectly timed too but thats for another day
Oh and as goes for the torque app, I have the paid for version and ive used it a lot recently and if im honest I cant really see a problem, its not 100% but it gives you a fair idea as to what is going on and for what it cost im not complaining
but the car is now back together again and it will be on the t4 at the thryberg meet on the 21st (asuming someone is there with one lol) where I can confirm things better and get a more up to date version of events

This makes more sense, although I wouldn't dare doubt anyone's work from what I've read here.
But, even then, the ECU should be picking this up and throwing more than low level misfires, imo.

Whatever, it seems obvious that there's something majorly wrong and there's no way breathers etc will be causing this, imo.

ello, right here's the next part

ok so now to remove the thermostat
remove the 2 clips holding the left hand pipe and take off the 3 pipes on the right of the thermostat housing
DSCN0429.jpg
then remove the securing bolt
DSCN0430.jpg
then pull out the thermostat housing and the rear pipe
DSCN0432.jpg
as you can see SD1 was correct and the housing was leaking at the bottom seal
DSCN0433.jpg
then clean the area ready for fitting of the new one which is just reversal of removal
i used a little clean engine oil on all of the rubber seals to aid fitting
DSCN0442.jpg

Delirious · 6th March 2015, 17:44

ok next job are the gauzes which were pretty simple
it was just a case of pushing them into their place in the rocker cover
and cleaned the faces on the cylinder head and rocker covers
DSCN0438.jpg
DSCN0441.jpg
then i used sealant on the faces ready for re-fitting
new gasket used
DSCN0436.jpg
and then refitted and re torqued the bolts down in the correct order
DSCN0439.jpg
DSCN0444.jpg
job done

Delirious · 6th March 2015, 18:35

ok next was the injectors
the seal kit i bought had each seal labelled A. being the top B the center and C the bottom
DSCN0449.jpg
so really easy to set up, lubricated each seal with a little clean engine oil and pushed the injector into place in the manifold

then cleaned both the faces on the cylinder heads for the manifolds to be fitted and again used some sealant on those faces
DSCN0450.jpg
DSCN0451.jpg

fitted a new gasket
DSCN0453.jpg

And then bolted the manifolds into place
DSCN0454.jpg
all good

Delirious · 6th March 2015, 18:48

Next was the Fuel Rail

The top of each injector was lubricated with a little engine oil
and the rail pushed into place
the end cap seal was replaced and the interconnecting pipe seal was also replaced, again a little engine oil to lubricate and they pushed home
DSCN0461.jpg
DSCN0463.jpg
then the clip was fitted, this was a little tricky as the end cap didnt want to fit fully in at first, but it went in the end
then i fitted the front bank fuel rail the same way
DSCN0465.jpg
tightened the 4 bolts up and checked the fitting
at this point i thought id reconnect the fuel pipe and check for leaks
DSCN0466.jpg
fortunatly for me all good

Delirious · 6th March 2015, 19:04

next was reconnecting the electronics
fitted the cam sensor back onto the front bank cylinder head
DSCN0468.jpg
and laid out the main front bank wiring loom, reconnecting the crank sensor
reconnected the injector wiring and plugged the alternator back in

DSCN0469.jpg
DSCN0469.jpg

and the front bank coil packs
DSCN0470.jpg
and then the rear injector wiring and coil packs
DSCN0472.jpg
and this is the mystery earth tag that you will see mentioned lots of times on this site as it is usually accidentally missed when refitting
DSCN0473.jpg

Delirious · 6th March 2015, 19:13

next is the black manifold
firstly fitted the 3 green seals onto the rear manifold
DSCN0475.jpg
then fitted the black seals into the black manifold
DSCN0476.jpg
DSCN0478.jpg
then its just a case of lowering the black manifold onto the metal ones and tightening
DSCN0480.jpg
then re-attach all the throttle wiring and breather pipes
DSCN0481.jpg

Delirious · 6th March 2015, 19:21

just a case of reattaching the last few bits
so front water pipes to the radiator
DSCN0482.jpg
the coolant bottle
DSCN0484.jpg
the airbox
DSCN0483.jpg
and the breather pipework
DSCN0487.jpg
DSCN0485.jpg
top up the coolant and bleed it through using the bleed screw on the lower coolant pipe
and job done
