My valver/172 project

[Matteh]

yeh geesus

the project is starting to get to me now

got the deadline looming and it still needs so many more bits to get it running

Reckon I still need:

172 downpipe - hopefully getting this tomorrow (and hopefully it'll include the lambdas!! but knowing how much i seem to have been stitched up on parts, it wont

idle control valve

crank position sensor (bought, but not sure when it will arrive)

vacuum tube for fuel rail

bracket made up to support the mk1 fuel rail

coolant temp sensor!! (why is this missing?!)

bit of pipe for one of the breathers (I think)

roll pin for the driveshaft (gave my last one away, I'm too kind )

2x adapters for the heater matrix (after the pipes were chopped, they're too small)


then I need to wire up the mk1 fan and get a fuel pump relay (it works atm, but on a constant live only)

I need to get my alternator charge light to work too

then things like guages etc would be nice

I need to find out why my aux belt is jumping 1 tooth towards the engine too


and ofcourse I need to see if this engine will actually work (or else Dan if you're reading this, I know where you live!!)

Nice one on getting it running! Will it idle? Take is that puff of blue smoke was just oil in the head after the rebuild?

 

[geesus69]

got more than me there mate!

as above why wont it idle?

 

[ben_p]

no ICV

 

[mini-valver]

^^It should still idle, just like a sack of s**t....

 

[ben_p]

well it would idle at about 4000rpm as there would be a huge hole after the TB

 

[Matteh]

yeh, i need to fit an ICV still

the battery is weak as fook and i dunno if the alternator is charging properly, so maybe it was just drained...

but im happy!

 

[geesus69]

i bet you are! i'd be over the moon if mine did that

 

[Beaniemoo]

WELL DONE THAT MAN TOP BOMBING!!!!

 

[Matteh]

well chuffed with it!

I just need to find somewhere to make me a downpipe tomorrow and ill be ready!

the problem i had is there is an 'earth' which seems to have about 80k resistance on it? hadnt connected it to the engine... as soon as i did, it fired in to (asbo) life!

 

[Mark One]

nice! good work there

 

[Matteh]

Beanie, could you give me a clue as to how to wire up the coolant temp guage and the rev counter (even if it only reads half for now?)

 

[Beaniemoo]

No trouble fella, moo's over tomorrow so i'll grab you on MSN.

 

[Matteh]

brilliant!

 

[Jay Payne]

well done Matt, excelent work.

 

[Matteh]

plugged in my fan relay... and now my fuel pump primes! crazy thing!

I'm insured on it (172 and mods declared!)

I taxed it today (and declared it as a 1998cc)

It has MOT (even though its been rebuilt )

the coolant is in! (my hose adapters arrived)

all I need is my exhaust really, the a few little bugs to iron out, like a coolant fan and the idle control valve and a bracket for my fuel rail

tomorrows plan is the exhaust though...

Got a downpipe off a pug 405 which fits the 172 manifold!

but the fun will be cutting and welding it to fit my existing exhaust


progress!

 

[Jay Payne]

not long now then mate

 

[Matteh]

if i felt like getting an ASBO, i'd go drive it now!

 

[Sean_J]

Good lad! How the hell did you find out that about the 405?!?!?!

Have you seen the forecast?! Need some thermals!

 

[geesus69]

that earth you were on about, towards the back of the engine is it? around the starter area ish?

 

[Jay Payne]

Could that be your earth wire i couldnt find on mine the other day?

 

[Matteh]

went to an exhaust place and just tried a few downpipes!

forecast looks grim!

 

[Matteh]

that earth you were on about, towards the back of the engine is it? around the starter area ish?

thats the one

orange and black covering?

 

[geesus69]

yeh sounds like it

that earth you were on about, towards the back of the engine is it? around the starter area ish?

thats the one

orange and black covering?

where have you connected it to? just anywhere on the block?

 

[Matteh]

yeh (thermostat housing as it was easiest - need to move it somewhere more secure i think)

spent all day today running around trying to sort my exhaust...

cut and measured all the pieces myself under the car and got them welded up

looks brilliant, but the bend right after the flange is about an inch and a half too far away from the flange, so i need to chop a section out and get it welded to bring it closer ... it just hits the bulkhead atm

so close!!

 

[Jay Payne]

What bore size is it matt? Looks a tad small in the pics

You could use this one as a template now and go get yourself a nice stainless made up

 

[Matteh]

the 'old' looking bits are my old 16v exhaust.. so only 2" i think

not measured the new stuff, but it looks big!

but yeh, at some point i'll replace it with a bigger size

the fact im not running a mid box or cat should help though?

 

[Matteh]

it's alive... sorta...

it runs but then after a while just dies - looks like its using oil too, but im not sure if thats cause the engien was completely dry before and the oil is still finding its way around?

 

[Matteh]

exhaust is on

i have gears

ive adjusted the clutch pedal so i can actually select gears...

problem i'm having is that the car will start and idle fine... occasionaly it might cut out... but restarting it is impossible

Im using a CTS out of a 1.6 as it looked the same - could this be causing issues, i've heard of this sort of problem being CTS related...

 

[geesus69]

i reckon that could well be your problem

can you cross reference the part numbers and see of they are the same?

 

[Matteh]

don't know the dialogys code for a 1.6

 

[geesus69]

ive got my old cps sensor in the garage if you want to try that (i put the new one on thinking that was causing my starting problem)

give me the part number for it tho as ive mixed the valver one up with the 172 one

 

[Matteh]

the connectors are different

ive not got any lambdas connected.. would that fox it?

 

[Matteh]

oooo

i still need to post your crash switch!!

I completely forgot

 

[geesus69]

the 2 black cps sensors i have both fit the same plug?! its the new blue style cps that has a different connector :S

i've only got the upstream lambda connected

oooo

i still need to post your crash switch!!

I completely forgot

no worries, in no rush

 

[Matteh]

posted off just now

 

[bmh.01]

don't know the dialogys code for a 1.6

CB1D for a Ph2 and afaik all the coolant temp sensors are the same.

hang on a minute, ive just realised you put CTS aswell matteh, i assume you mean CPS as what would the coolant temp sensor do to stop it running?!

 

[Matteh]

i meant CTS as on the mk1s its been known to cause issues with bad idle and hot starts
